7-12-2024 MONTE CORONA, VALENCIA - CANDELABRA ALOE (Aloe arborescens)

Aloe arborescens, the krantz aloe or candelabra aloe, is a species of flowering succulent perennial plant that belongs to the genus Aloe, which it shares with the well known and studied Aloe vera. The specific epithet arborescens means "tree-like". Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, winter blooming, and attraction for birds, bees, and butterflies.

Aloe arborescens is a large, multi-headed, sprawling succulent, and its specific name indicates that it sometimes reaches tree size. A typical height for this species is 2–3 metres (6.6–9.8 ft) high. Its leaves are succulent and are green with a slight blue tint. Its leaves have small spikes along its edges and are arranged in rosettes situated at the end of branches. Flowers are arranged in a type of inflorescence called a raceme. The racemes are not branched but two to several can sprout from each rosette. Flowers are cylindrical in shape and are a vibrant red-orange color.

Taxonomically, it forms part of the Arborescentes series of very closely related Aloe species, together with Aloe pluridens and Aloe mutabilis.

Aloe arborescens is endemic to the south eastern part of Southern Africa. Specifically, this range includes the countries of South Africa, Malawi, Mozambique, and Zimbabwe. It has the third largest distribution amongst the aloe genus. Although Aloe arborescens has adapted to many different habitats, its natural habitat usually consists of mountainous areas, including rocky outcrops and exposed ridges. Its common name krantz aloe refers to the Afrikaans word "krans" (spelling possibly influenced by German "Kranz"), which means a rocky cliff. Its habitat can vary, and it is one of only a few species of aloe that is found growing from sea level up to the tops of mountains.

It is also widely distributed (to the point of becoming naturalized) in the western Mediterranean, Australia, California, Japan, South Korea and the Marshall Islands. It is an invasive species in Portugal.

Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, and winter blooming. The sweet nectar attracts birds, butterflies, and bees. With a minimum temperature of 10 °C (50 °F), in temperate regions it is grown under glass. The cultivar A. arborescens 'Variegata' has gained the Royal Horticultural Society's Award of Garden Merit. In Southern Africa, Aloe arborescens is traditionally planted around kraals (domestic stock enclosures) as a living fence or security hedge. It often happens that the position of old kraals can still be seen many years after they have been abandoned, because the aloes persist. It is easily propagated by cuttings.

6-12-2024 CREU DE LONGA, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)


The common kestrel, Falco tinnunculus, is a bird of prey from the kestrel group within the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, it is often simply referred to as the "kestrel." This raptor is small compared to other birds of prey but larger than most songbirds, with long wings and a distinctive long tail.

Males and females exhibit sexual dimorphism in their plumage. The male has a blue-grey cap and tail with a black tip bordered by a narrow white rim. Its back is chestnut with black spots, and the underside is buff with black streaks. The female is larger and lacks the blue-grey coloring, having a brown back with black bars and a similar underside to the male. Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.

The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

6-12-2024 CREU DE LONGA, ALBUFERA - BLACK HEADED GULL (Chroicocephalus ridibundus)

The black-headed gull (Chroicocephalus ridibundus) is a small, nimble gull with a wingspan ranging from 94 to 110 cm and a body length of 37 to 44 cm. It weighs between 190 and 400 grams. Despite its name, the adult's summer plumage features a chocolate-brown head, which can appear black from a distance. The body is pale grey, and the primary wing feathers are tipped with black. The bill and legs are a striking red. In winter, the brown head is replaced by a white one with dark spots. Juveniles are mottled with brown spots and have a black band on the tail. There is no sexual dimorphism in plumage.

This species nests in colonies on the ground in large reed beds, marshes, or islands within lakes. It is not pelagic and is seldom seen far from coasts.

The black-headed gull breeds across much of the Palearctic, including Europe and coastal eastern Canada. It is migratory, wintering further south, but some remain in the milder westernmost areas of Europe. It is also present in northeastern North America and occasionally seen as far south as Virginia and some Caribbean islands.

6-12-2024 CREU DE LONGA, ALBUFERA - EURASIAN GREATER CORMORANT


The great cormorant (Phalacrocorax carbo), a robust seabird, is cloaked in predominantly black plumage. It is a member of the cormorant family, with a widespread distribution. The species exhibits considerable size variation across its range, with males generally larger than females. Notable features include a longish tail and a distinctive yellow throat-patch. During the breeding season, adults boast white patches on their thighs and throat.

To identify the great cormorant, look for its large size, heavy build, and thick bill. It lacks a crest and its plumage does not have a green tinge, distinguishing it from the common shag. In North America, it is bulkier than the double-crested cormorant and has less yellow on the throat and bill. The white thigh patches are a key identifier.

Great cormorants are found in a variety of aquatic environments including seas, estuaries, freshwater lakes, and rivers. They often nest in colonies close to these water bodies.

This species has a broad distribution, breeding across the Old World, Australia, and the Atlantic coast of North America. Northern populations tend to migrate southward in winter, seeking coasts rich in fish. 


Great cormorants are generally silent but may emit guttural noises at breeding colonies. They are known for their wing-drying posture, often seen with wings outstretched to dry after diving.

Mostly silent, the great cormorant vocalizes with guttural sounds in the vicinity of its breeding colonies.

Great cormorants typically nest in colonies near wetlands, rivers, or sheltered inshore waters, often returning to the same site annually. Their nests are constructed from sticks and can be located in trees, on cliff ledges, or on predator-free ground. They lay clutches of three to five pale blue or green eggs, which are incubated for about 28 to 31 days.

These birds are piscivorous, diving to catch fish such as wrasses, sand smelt, flathead, and common soles. They exhibit seasonal dietary shifts, preferring larger fish in colder temperatures. Their foraging efficiency is influenced by the size of the prey rather than the quantity.

The great cormorant is currently listed as Least Concern by the IUCN. Conservation efforts have led to a population rebound, with approximately 1.2 million birds in Europe alone. However, their increasing numbers have led to conflicts with fisheries due to predation on fish stocks.

4-12-2024 CREU DE LONGA, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)


The common kestrel (Falco tinnunculus), also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".

This species occurs over a large native range. It is widespread in Europe, Asia and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.

In the cool-temperate parts of its range, the common kestrel migrates south in winter; otherwise it is sedentary, though juveniles may wander around in search for a good place to settle down as they become mature. It is a diurnal animal of the lowlands and prefers open habitat such as fields, heaths, shrubland and marshland. It does not require woodland to be present as long as there are alternative perching and nesting sites like rocks or buildings. It will thrive in treeless steppe where there are abundant herbaceous plants and shrubs to support a population of prey animals. The common kestrel readily adapts to human settlement, as long as sufficient swathes of vegetation are available, and may even be found in wetlands, moorlands and arid savanna. It is found from the sea to the lower mountain ranges, reaching elevations up to 4,500 m (14,800 ft) ASL in the hottest tropical parts of its range but only to about 1,750 m (5,740 ft) in the subtropical climate of the Himalayan foothills.

4-12-2024 CREU DE LONGA, ALBUFERA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


The Great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Males are typically larger and heavier than females. It has a longish tail and yellow throat patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters, the Great cormorant can be distinguished from the Common shag by its larger size, heavier build, thicker bill, lack of a crest, and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the Double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants.

Great cormorants occur throughout Europe, Asia, Australia, Africa, and northeastern coastal North America. They may be both resident and migratory. Throughout the year in some areas, large groups remain within the breeding range. Greta cormorants frequent open marine environments and inland waters. They inhabit sandy or rocky sheltered coasts and estuaries and are rarely seen any distance from the coast. This species breeds on cliffs and inshore islands, among boulders and man-made structures. Birds that nest inland will breed on trees, bushes, and reedbeds, and even on bare ground.


The Black stork (Ciconia nigra) is a large elegant wading bird that is widespread but uncommon species throught its native range. Black storks are long-distance migrants traveling on average between 37 and 80 days. During their long migration, they must cross the Mediterranean at the narrowest points, and many birds travel south through the Bosphorus, as well as the Sinai and Gibraltar.

The Black stork has long red legs, a long neck, and a long, straight, pointed red beak. The plumage is black with a purplish green sheen, except for the white lower breast, belly, armpits, axillaries, and undertail coverts. The breast feathers are long and shaggy, forming a ruff that is used in some courtship displays. The black stork has brown irises and bare red skin around its eyes. The sexes are identical in appearance, except that males are larger than females on average. Molting takes place in spring, with the iridescent sheen brighter in new plumage. It walks slowly and steadily on the ground and like all storks, it flies with its neck outstretched. The juvenile resembles the adult in plumage, but the areas corresponding to the adult black feathers are browner and less glossy. The scapulars, wing, and upper tail coverts have pale tips. The legs, bill, and bare skin around the eyes are greyish-green. It could possibly be confused with the juvenile yellow-billed stork, but the latter has paler wings and mantle, a longer bill, and white under the wings.

During the summer, Black storks are found from Eastern Asia (Siberia and northern China) west to Central Europe, reaching Estonia in the north, Poland, Lower Saxony and Bavaria in Germany, the Czech Republic, Hungary, Italy, and Greece in the south, with an outlying population in the central-southwest region of the Iberian Peninsula. Black storks are migratory and spend winters in tropical Africa and Asia; certain populations are sedentary or dispersive. There is also an isolated population in Southern Africa. Black storks prefer to live in more wooded areas and breed in large marshy wetlands with interspersed coniferous or broadleaved woodlands. They are also found in hills and mountains with creeks nearby. They usually inhabit ponds, rivers, edges of lakes, estuaries, and other freshwater wetlands. Black storks prefer to stay far from areas inhabited by humans and although they occur in more agricultural areas in the Caspian lowlands, they try to avoid close contact with people.

Black storks are wary birds. They usually spend time alone or in pairs, or flocks of up to 100 birds when migrating or during winter. Black storks are active during the day. They forage for food mostly in fresh water, though they may look for food on dry land at times. They wade patiently and slowly in shallow water, often alone or in a small group if food is plentiful. They may shade the water with their wings while hunting. In India, they often forage with White storks, Woolly-necked storks, Demoiselle cranes, and Bar-headed geese. Black storks communicate using various calls. Their main call is a 'chee leee', which sounds like a loud inhalation. They make a hissing call as a warning or threat. When displaying males produce a long series of wheezy raptor-like squealing calls. The young clatter their bills when aroused. Black storks also use an up-down display for a number of interactions with other members of the species. Here a stork positions its body horizontally and quickly bobs its head up from down-facing to around 30 degrees above horizontal and back again while displaying the white segments of its plumage prominently, and this is repeated several times. The display is used as a greeting between birds, and - more vigorously - as a threat display.

1-12-2024 MONTE CORONA, VALENCIA - CAMPONOTIN ANT (Camponotus sylvaticus)

Camponotini is a tribe containing 2 extinct ant genera and 8 extant ant genera, including Camponotus (carpenter ants). Ants in the Camponotini tribe are the primary hosts of Ophiocordyceps unilateralis, also called the zombie-ant fungus.

VILLALONGA RESERVOIR, VALENCIA - WALNUT ORBWEAVER (Nuctenea umbratica)


Nuctenea umbratica, the walnut orb-weaver spider, is a species of spider in the family Araneidae.

The species name umbratica means "living in the shadows" in Latin.

The walnut orb-weaver spider is very wide and flattened, with a leathery skin. Its color ranges from red brown and grey brown to black, with a dark, yellowish to yellow-greenish leaf-like flecked marking on its opisthosoma, where small dents are visible. These are the onsets of muscles that flatten the abdomen.

Female N. umbratica can reach up to 15 mm in size; the males grow only up to 8 mm.

The spider hides during the day outside of buildings in wall crevices or under loose bark. They are very common in Central Europe; females occur all year, while males appear mostly during the summer. This spider has a flattened body, helping it to secrete itself in cracks and crevices. Walnut orb-weaving spiders are capable of concealing themselves in very confined spaces. This tends to act as a defensive advantage and increases the number of locations an orb-web can be effectively constructed.

In the evening the spider constructs an orb-web that can be up to 70 cm in diameter. A signaling thread leads from the web to her hiding place. After dusk she sits in the web's center.

Nuctenea umbratica (Clerck, 1757) – Europe to Azerbaijan

Nuctenea umbratica nigricans (Franganillo, 1909) – Portugal

Nuctenea umbratica obscura (Franganillo, 1909) – Portugal

3-12-2024 VILLALONGA RESERVOIR, VALENCIA - GREY HERON (Ardea cinerea)


The Grey Heron is a large grey heron having white and black accents, a white crown with black plumes, black belly, and white thighs.

Adult: The adult has a white head (including crown, sides, throat) with a broad black eye stripe extending from above the eye to the back of the crown and continuing as a crest with several elongated, black plumes. The long and heavy bill is yellow with a dull brown suffusion along the lower bill and top of the upper bill. The irises are yellow and lores are yellow turning darker green around the eye. The chin, throat, and neck are light grey to white, with the neck being tinged buff at its base. The foreneck is grey-white with two distinct broken black streaks running parallel down the median. The upper back and hind neck are pale grey, the lower back and upper wing blue-grey. Pale grey lanceolate feathers occur along the back. The flight feathers are dark grey to black contrasting with the paler upper wings and uniform grey to white under the wing. At rest, a black “shoulder” patch with a few white feathers is formed at the forward bend of the wing. The flanks are grey, the sides of the belly black, but the rest of the under parts are light grey to white, including the feathered thighs. The breast feathers are loose and elongated. The tail is grey. The legs and feet are green-grey to yellow-brown, varying in shade with age and season; the upper leg is paler (more yellow) than the lower leg.

3-12-2024 VILLALONGA RESERVOIR, VALENCIA - VESPERID BEETLE (Vesperus xatarti)

Vesperus xatarti is a species of brown coloured beetle in the family Vesperidae, found in the Balearic Islands, France, and Spain.

Vesperus xatarti, a species known from Spain ans South-West France, has been described from Pyrénées Orientales by Étienne Mulsant in 1839 [❖]. Larvae of V. xatarti develops in ground at the roots of different plants (often reported from Vitis vinifera). Life cycle several years, with pupation in ground. Adults are active from early autumn over winter, especially in warm littoral areas. Adults are nocturnal - males fly (and can be attracted by light, especially ultra-violet), females (hidden under rocks during the day) move on the ground at night and attract males with a highly active sex pheromone. Mating occurs almost immediately after hatching, females lay eggs approximately six days later, and adult survival does not exceed 24 hours after copulation.

Body length: ♂♂ 18 - 25 mm / ♀♀ 22-35 mm

Life cycle: 3 and more years

Adults in: October - March

Host plant: polyphagous on roots of decidous trees and shrubs (Celtis, Vitis vinifera, Olea etc.)

Distribution: S-W France (Pyrénées Orientales), Spain.

2-12-2024 LORX, VALENCIA - COMMON CHAFFINCH (MALE) (Fringilla coelebs)

The Eurasian chaffinch, common chaffinch, or simply the chaffinch (Fringilla coelebs) is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate.

The chaffinch breeds in much of Europe, across the Palearctic to Siberia. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically four or five eggs, which hatch in about 13 days. The chicks fledge in around 14 days, but are fed by both adults for several weeks after leaving the nest. Outside the breeding season, chaffinches form flocks in open countryside and forage for seeds on the ground. During the breeding season, they forage on trees for invertebrates, especially caterpillars, and feed these to their young. They are partial migrants; birds breeding in warmer regions are sedentary, while those breeding in the colder northern areas of their range winter further south.

The eggs and nestlings of the chaffinch are taken by a variety of mammalian and avian predators. Its large numbers and huge range mean that chaffinches are classed as of least concern by the International Union for Conservation of Nature.

30-11-2024 RIO SERPIS, VALENCIA - GREY HERON (Ardea cinerea)

The Grey Heron is a large grey heron having white and black accents, a white crown with black plumes, black belly, and white thighs.

Adult: The adult has a white head (including crown, sides, throat) with a broad black eye stripe extending from above the eye to the back of the crown and continuing as a crest with several elongated, black plumes. The long and heavy bill is yellow with a dull brown suffusion along the lower bill and top of the upper bill. The irises are yellow and lores are yellow turning darker green around the eye. The chin, throat, and neck are light grey to white, with the neck being tinged buff at its base. The foreneck is grey-white with two distinct broken black streaks running parallel down the median. The upper back and hind neck are pale grey, the lower back and upper wing blue-grey. Pale grey lanceolate feathers occur along the back. The flight feathers are dark grey to black contrasting with the paler upper wings and uniform grey to white under the wing. At rest, a black “shoulder” patch with a few white feathers is formed at the forward bend of the wing. The flanks are grey, the sides of the belly black, but the rest of the under parts are light grey to white, including the feathered thighs. The breast feathers are loose and elongated. The tail is grey. The legs and feet are green-grey to yellow-brown, varying in shade with age and season; the upper leg is paler (more yellow) than the lower leg.

During breeding, the black crest plumes attain full development and long white lanceolate plumes develop along the back, lower foreneck and breast. The iris, bill, and legs flush deep orange to red. The bill may retain some of this color until after the young have hatched.

Variation: The sexes are identical in plumage, but the male averages larger (Boev 1987a, b, c). Considerable individual variation can exist, including birds that are various shades of grey, white, black, brown, or buff (e.g., Krotoski 1983, Sanders and Ebels 1998). Geographic patterns of variation are recognized taxonomically. The European-African race, A. c. cinerea, is as described above. The buff color on the neck decreases geographically from east to west, and the eastern race jouyi typically lacks the buff color and is markedly paler on the neck, upper wing feathers, and back plumes (Vaurie 1965). The island race firasa averages larger, especially in bill and legs than cinerea. The West African monicae is paler, looking sufficiently pale grey to white to be distinguishable from migrant A. c. cinerea (Erard et al. 1986). In the western Indian Ocean, Grey Herons breeding on various islands vary from firasa-type to cinerea–type (Penny 1974, Langrand 1990).

Juvenile: Juvenile Grey Herons are more uniformly grey than adults and lack black plumage highlights and ornamental plumes. They have a grey to dark grey crown. The chin is white and foreneck appears brown-grey. The upper parts are grey-brown and under parts grey with brown grey streaking on the foreneck. The soft parts are duller than in the adult's. Legs are dark grey, the upper legs being paler and tinged yellow-green. In the first autumn and winter the upper parts become more blue-grey. The feathers of the back and breast are moderately elongated. From the second autumn subadult plumage is assumed, differing from the full adult in having the forehead and crown grey instead of white and the black of the sides of the belly less developed. Juvenile plumages are retained into the second year and vary among individuals from relatively more juvenile to more adult.


Chick: The chick is brown-grey above, with notable head crest, and white below. Irises are yellow, bill grey, and legs green-grey.

Voice: The Grey Heron is a rather vocal heron. Its distinctive vocalization is the “Frarnk” call, a loud far carrying flight call. The “Go” call, rendered “go, go, go”, is an alarm call. The “Oooo” call is an aggressive call, also given in the Forward display. The Oooo call is also used in the Stretch display, becoming a more gurgling “oooo” when given by both sexes in the crouched part of the Stretch. At the breeding colony, the species is very vocal, uttering a variety of yelps, squawks and other, softer notes. The “Rwo” call is the male’s advertising call. The “Arre” call is a landing call, rendered “arre, arre”, tending to a clucking on alighting. The Snap Display ends in a “Clop”. A Greeting Display includes bill-snaps. Bill Clappering occurs among pairs during formation and when in contact.

Weights and measurements: Length: 90-98 cm. Weight: 1,020-2,073 g.

30-11-2024 RIO SERPIS, VALENCIA - BLACK REDSTART (MALE) (Phoenicurus ochruros)


The Black redstart (Phoenicurus ochruros) is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae).

The adult male of this species is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the common redstart; at any age, the grey axillaries and underwing coverts are also distinctive. There are two distinct forms in first calendar year males at least in western subspecies, with the first ('carei') being similar to females and the second ('paradoxus') approaching adult males but lacking the whitish wing panel that does only develop during post-breeding molt of wing feathers in the second calendar year. This second form is much rarer than the first.

Black redstarts breed in south and central Europe and Asia and north-west Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. They are resident in the milder parts of their range, but north-eastern birds migrate to winter in southern and western Europe and Asia, and north Africa. In some areas, birds that breed in mountains move to lower elevations in winter. Black redstarts inhabit stony ground in mountains, particularly cliffs and stony slopes with xerophytic vegetation. They are also found in villages, and urban areas and often occur in large industrial complexes that have bare areas and cliff-like buildings.

2-8-2017 CENTRAL PARK, BUDAPEST - DOUBLE BARRED FINCH (Taeniopygia bichenii)


The double-barred finch (Stizoptera bichenovii ) is an estrildid finch found in dry savannah, tropical (lowland) dry grassland and shrubland habitats in northern and eastern Australia. It is sometimes referred to as Bicheno's finch or as the owl finch, the latter of which owing to the dark ring of feathers around the face.

The double-barred finch is a 10–11 cm long munia-like bird. It has a white face bordered with black, brown upperparts and throat, and white underparts. The throat and underparts are separated by another black line. The wings are patterned in brown and white. The sexes are similar, but juveniles are duller and browner. A less common subspecies with brown or black underparts is known to exist.

The double-barred finch is granivorous and highly gregarious. Nests are built in grass, bushes or low trees, with four to six eggs laid per clutch. The call is a soft tet or a louder peew, and the song is a soft fluting, which is somewhat like the zebra finch.

This species occurs in Europe, North Africa and Asia. It was recently rediscovered in the Maltese islands.

Oedipoda caerulescens is a medium-sized grasshopper, between 15 and 21 mm for males and between 22 and 28 mm for females. The body coloration varies greatly depending on the substrate on which the animals have developed: reddish brown, gray, yellowish, or even completely dark or bright. The forewings are crossed most often by two or three pale bands, but the most striking characteristic, very visible when the insect flies away, is the bright coloration of the hind wings, a beautiful turquoise highlighted with a black marginal stripe. Furthermore, the posterior femora have a notch on their upper surface. At rest, confusion is possible with other Oedipoda species such as O. germanica.


Oedipoda caerulescens frequents dry areas with low and open vegetation: dunes, heathlands, grasslands on sand and sunlit limestone rocks. Many stations correspond to land recently used for human activities, such as coal spoil heaps, quarries and pits, the ballast of railway tracks, etc. It is exclusively a terrestrial insect, and its cryptic coloration often matches its substrate. It presses itself to the ground and remains motionless, and jumps only at the very close approach of danger. A remarkable behavior is the "hook" landing which serves to confuse potential attackers. Thus, the grasshopper lands and swings round to face the direction it has come from. The sudden disappearance of the blue hind wings of the adult makes it difficult for predators to shift quickly enough to a different kind of search to relocate the prey. The female lays her eggs in bare, dry soil. In this species, acoustic emissions are virtually nonexistent. The diet consists mainly of grasses.

29-11-2024 MONTE CORONA, VALENCIA - SLENDER SOWTHISTLE (Sonchus tenerrimus)


Sonchus tenerrimus is a species of flowering plant in the family Asteraceae known by the common name slender sowthistle. It is native to the Mediterranean region of southern Europe, northern Africa, and the Middle East. It has been found as well in several other locations around the world, historically in association with ship ballast in coastal regions. It has become naturalized in a few places, such as California in the United States and Baja California in Mexico.

Sonchus tenerrimus is an annual or perennial herb producing a slender, branching stem up to about 80 centimeters (32 inches) tall. The leaves are deeply divided into many variously shaped lobes which may have toothed edges or smaller lobes. The inflorescence bears flower heads lined with glandular, hairy to woolly phyllaries. They are filled with numerous yellow ray florets but no disc florets. The fruit is an achene up to a centimeter long including its pappus.

27-11-2024 MARJAL DE MOROS PUCOL, VALENCIA - NORTHERN SHOVELER (MALE) (Spatula clypeata)

The Northern shoveler (Spatula clypeata) is a widespread species of duck unmistakable in the northern hemisphere due to its large spatulate bill. In Britain, it is known simply as the shoveler. One part of its scientific name Spatula is the Latin for a "spoon" or "spatula"; the other part is derived from the Latin clypeata and can be translated as "shield-bearing".

During the breeding season, the male of this species has an iridescent dark green head, white breast, and chestnut belly and flanks. In flight, pale blue forewing feathers are revealed, separated from the green speculum by a white border. In early fall the male will have a white crescent on each side of the face. In non-breeding (eclipse) plumage, the male resembles the female. The female is a drab mottled brown like other dabblers, with plumage much like a female mallard, but easily distinguished by the long broad bill, which is gray-tinged with orange on the cutting edge and lower mandible. The female's forewing is gray.


Northern shovelers breed in wide areas across Eurasia, western North America, and the Great Lakes region of the United States. They are strongly migratory and winter in southern Europe, Africa, the Indian Subcontinent, the Caribbean, northern South America, the Malay Archipelago, Japan, and other areas. In North America, they winter south of a line from Washington to Idaho, from New Mexico east to Kentucky, and along the Eastern Seaboard as far north as Massachusetts. Northern shovelers are birds of open wetlands, such as wet grassland or marshes with some emergent vegetation. Preferred feeding areas include lakes, estuaries, coastal shorelines, salt marshes, flooded fields, and agricultural ponds.

Northern shovelers are social ducks that live in small flocks and coexist peacefully with many other species. They feed during the day by dabbling for plant food, often by swinging their bill from side to side and using the bill to strain food from the water. Their wide-flat bill is equipped with well-developed lamellae; these are small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. This adaptation gives them an advantage over other puddle ducks, with which they do not have to compete for food resources during most of the year. Thus, mud-bottomed marshes rich in invertebrate life are their habitat of choice. During the midday heat, the birds usually rest on land near the water. Northern shovelers are fairly quiet and communicate with each other only in certain situations; males have a low clunking call, whereas females have a light Mallard-like quack.

27-11-2024 MARJAL DE MOROS PUCOL, VALENCIA - ZITTING CISTICOLA (Cisticola juncidis)


The zitting cisticola or streaked fantail warbler (Cisticola juncidis ) is a widely distributed Old World warbler whose breeding range includes southern Europe, Africa (outside the deserts and rainforest), and southern Asia down to northern Australia. A small bird found mainly in grasslands, it is best identified by its rufous rump; as well, it lacks any gold on the collar and the brownish tail is tipped with white. During the breeding season, males have a zigzagging flight display accompanied by regular "zitting" calls that have been likened to repeated snips of a scissor. They build their pouch nest suspended within a clump of grass.

The zitting cisticola is 10 to 12 cm (3.9 to 4.7 in) in length. It is brown above, heavily streaked with black markings. The underparts are whitish, and the tail is broad, white-tipped and flicked frequently, giving rise to the alternative name for the species. The adult males have less crown streaking and more back marking than the females, but there are no great difference between the sexes or the eighteen geographical races. The absence of a nuchal collar separate it from the golden-headed cisticola (Cisticola exilis ). In the non-breeding season, they tend to skulk within the grass and can be hard to spot.


This species is found mainly in grassland habitats, often near water. Most populations are resident, but some East Asian populations migrate south to warmer areas in winter. In the Himalayas, they ascend to about 1,900 m (6,200 ft) during summer but are below 1,300 m (4,300 ft) in the winter. This species is a rare vagrant to northern Europe, mostly as a spring overshoot. Its European range is generally expanding, although northern populations are especially susceptible to hard winters.


Zitting cisticolas are very small insectivorous birds, sometimes found in small groups. The breeding season is associated with the rains. Two broods a year occur in many regions. Males are generally polygynous, but some are monogamous. The male builds the initial nest structure deep in the grasses, and invites females using a special display. Females that accept the male complete the nest. The nest is made by binding living leaves into the soft fabric of felted plant-down, cobwebs, and grass. The zitting cisticola's nest is a cup shape with a canopy of tied-together leaves or grasses overhead for camouflage; 3–6 eggs are laid. The female incubates the egg. The eggs hatch after about 10 days. More than one brood may be raised. Females change their mates frequently and rarely stay within the same territory, while males are less mobile, maintaining non-overlapping song-territories which shift from day to day. Females can sometimes breed in their first year.

27-11-2024 MARJAL DE MOROS PUCOL, VALENCIA - EURASIAN GREEN WINGED TEAL (FEMALE) (Anas crecca ssp. crecca)


The Eurasian teal (Anas crecca), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal.

It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (A. carolinensis) was formerly (and sometimes is still) considered a subspecies of A. crecca.

The Eurasian teal breeds across the Palearctic and mostly winters well south of its breeding range. However, in the milder climate of temperate Europe, the summer and winter ranges overlap. For example, in the United Kingdom and Ireland a small summer population breeds, but far greater numbers of Siberian birds arrive in winter. In the Caucasus region, western Asia Minor, along the northern shores of the Black Sea, and even on the south coast of Iceland and on the Vestmannaeyjar, the species can be encountered all year, too.

In the Caucasus region, western Asia Minor, along the northern shores of the Black Sea, and even on the south coast of Iceland and on the Vestmannaeyjar, the species can be encountered all year, too.

In winter, there are high densities around the Mediterranean, including the entire Iberian Peninsula and extending west to Mauretania; on Japan and Taiwan; as well as in South Asia. Other important wintering locations include almost the entire length of the Nile Valley, the Near East and Persian Gulf region, the mountain ranges of northern Iran, and South Korea and continental East and Southeast Asia. More isolated wintering grounds are Lake Victoria, the Senegal River estuary, the swamps of the upper Congo River, the inland and sea deltas of the Niger River, and the central Indus River valley. Vagrants have been seen in inland Zaire, Malaysia, on Greenland, and on the Marianas, Palau and Yap in Micronesia; they are regularly recorded on the North American coasts south to California and South Carolina, including annual sightings on the island of Newfoundland.

From tracking wintering teal in Italy, most individuals departed the wintering grounds between mid-February and March, using the Black-Sea-Mediterranean flyway to reach their breeding grounds, from central Europe to east of the Urals, by May. This slow migration is due to long stopovers near the start of migration, mainly in south-eastern Europe.

Altogether, the Eurasian teal is much less common than its American counterpart, though still very plentiful. Its numbers are mainly assessed by counts of wintering birds; some 750,000 are recorded annually around the Mediterranean and Black Seas, 250,000 in temperate western Europe, and more than 110,000 in Japan. In 1990 and 1991, a more detailed census was undertaken, yielding over 210,000 birds wintering in Iran, some 109,000 in Pakistan, about 77,000 in Azerbaijan, some 37,000 in India, 28,000 in Israel, over 14,000 in Turkmenistan and almost 12,000 in Taiwan. It appears to be holding its own currently, with its slow decline of maybe 1–2% annually in the 1990s – presumably mainly due to drainage and pollution of wetlands – not warranting action other than continuing to monitor the population and possibly providing better protection for habitat on the wintering grounds. The IUCN and BirdLife International classify the Eurasian teal as a species of Least Concern, unchanged from their assessment before the split of the more numerous A. carolinensis.

27-11-2024 MARJAL DE MOROS PUCOL, VALENCIA - LITTLE EGRET (Egretta garzetta)

The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.

The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread.

The Little Egret is a small white heron with attractive white plumes on crest, back and chest, black legs and bill and yellow feet. It first appeared in the UK in significant numbers in 1989 and first bred in Dorset in 1996. Its arrival followed naturally from a range expansion into western and northern France in previous decades. It is now at home on numerous south coast sites, both as a breeding species and as a winter visitor.

With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family.

Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.

The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.

26-11-2024 MONTE CORONA, VALENCIA - SMALL FRUIT FLY (Genus Drosophila)


Drosophila (/drəˈsɒfɪlə, drɒ-, droʊ-/ is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly.

One species of Drosophila in particular, Drosophila melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "Drosophila" are often used synonymously with D. melanogaster in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, behavior, and breeding habitat.

25-11-2024 RIO JUCAR CULLERA, VALENCIA - EURASIAN GREAT CORMORANT

The Great cormorant (Phalacrocorax carbo) is a widespread member of the cormorant family of seabirds. Many fishermen see in the Great cormorant a competitor for fish. Because of this, it was hunted nearly to extinction in the past but luckily due to conservation efforts, its numbers increased.

The Great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Males are typically larger and heavier than females. It has a longish tail and yellow throat patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters, the Great cormorant can be distinguished from the Common shag by its larger size, heavier build, thicker bill, lack of a crest, and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the Double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants.

Great cormorants occur throughout Europe, Asia, Australia, Africa, and northeastern coastal North America. They may be both resident and migratory. Throughout the year in some areas, large groups remain within the breeding range. Greta cormorants frequent open marine environments and inland waters. They inhabit sandy or rocky sheltered coasts and estuaries and are rarely seen any distance from the coast. This species breeds on cliffs and inshore islands, among boulders and man-made structures. Birds that nest inland will breed on trees, bushes, and reedbeds, and even on bare ground.


Great cormorants are active during the day and are social birds, usually leaving roosts to forage early in the morning and returning within an hour. Little time each day is spent foraging, although parents with young tend to forage for longer. Much of the day is spent resting and preening near foraging areas or at roosts. Great cormorants generally are not aggressive towards one another, apart from at nest sites, where they exhibit territorial behavior. There may be dominance hierarchies. Outside of the breeding season, they usually gather in mixed-age, mixed-sex groups.


Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.

25-11-2024 RIO JUCAR CULLERA, VALENCIA - CRETAN VIPER'S-BUGLOSS (Echium creticum)


Echium creticum, the Cretan viper's bugloss, (syn. Echium calycinum Viv., Echium rubrum Moench, Echium sericeum Vahl, Echium violaceum L.) is a species of flowering plant in the family Boraginaceae. It is native to the western Mediterranean Basin. It is also used as an ornamental plant.

Viper's bugloss is a toxic plant of medium severity. All parts of the plant are poisonous when ingested, and can cause symptoms of varying harm, such as pain of the lips, tongue, and throat, vomiting, stomach pain and diarrhea, and liver damage.

24-11-2024 MONTE CORONA, VALENCIA - MEDITERRANEAN MANTIS (MALE) (Iris oratoria)

The European mantis (Mantis religiosa) is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises). Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose. It resembles a praying attitude. Both males and females have elongated bodies with two pairs of wings. The most striking features that all Mantodea share are a very mobile, triangular head with large compound eyes and their first pair of legs (the 'raptorial legs'), which is highly modified for the efficient capture and restraint of fast-moving or flying prey.

In Germany, M. religiosa is listed as Gefährdet on the German Red List on the basis of an assessment from 1998. It is not supposed to be caught or held as a pet. At a global level, it is assessed by the IUCN as least concern.

The great variation in the coloration of M. religiosa from different shades of yellow, brown, green, and sometimes black has been the cause of numerous hypotheses and studies for over 100 years. However, no generally accepted answer about reason, benefit, or mechanism of the coloration or the change of coloration has been found.

Di Cesnola observed in 1904 that green mantids were found on fresh green grass, whereas brown individuals seemed to prefer brown grass burned by the sun. When forced to change the location as to no longer match their coloration, almost all the ‘not matching’ animals were killed by predators such as birds. This indicates a camouflaging purpose of the coloration.

Przibram also observed in 1907 that a change in temperature can trigger a change in coloration: animals that hatched in a cold environment turned green after moulting when heat and sunlight were provided. Without the change in temperature and only a change in the color of the background, no change in coloration occurred. This finding contradicts with Di Cesnola, who claims to have observed the animals within the same time and location (and therefore the same temperature).
