11-10-2017 DEVESA, VALENCIA - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)



Striking large black-and-white wader with a thin, straight bill and bright pink legs, found in wetlands with open shallow water throughout much of Africa and Eurasia, often in brackish habitats. Some populations are migratory, departing northerly breeding grounds for warmer southern regions. Often forms noisy colonies on bare ground near water. Essentially unmistakable throughout much of its range, but compare with Pied Stilt in parts of Southeast Asia. Feeds by wading in water, picking from the water surface with its needle-like bill. In flight, long pink legs stick out far beyond the tail. Calls loudly and stridently, especially when alarmed during the breeding season.


The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".

11-10-2017 ULAL DE BOLDOVI, VALENCIA - RED ADMIRAL BUTTERFLY (Vanessa atalanta)


Vanessa atalanta, the red admiral or, previously, the red admirable, is a well-characterized, medium-sized butterfly with black wings, red bands, and white spots. It has a wingspan of about 2 inches (5 cm). It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The red admiral is widely distributed across temperate regions of North Africa, the Americas, Europe, Asia, and the Caribbean. It resides in warmer areas, but migrates north in spring and sometimes again in autumn. Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). The adult butterfly drinks from flowering plants like Buddleia and overripe fruit. Red admirals are territorial; females will only mate with males that hold territory. Males with superior flight abilities are more likely to successfully court females. It is known as an unusually calm butterfly, often allowing observation at a very close distance before flying away, also landing on and using humans as perches.


The forewing of this butterfly bears on a black ground an oblique vermilion bandand a group of white subapical spots. On the hindwing the larger portion of the distal margin is red, with a row of small black spots and at the anal angle an elongate blue spot. The underside is partly variegated with blue; the forewing is on the whole similar in markings to the upper, while the hindwing is brightly variegated and clouded, bearing black markings, of which those in the cell resemble a figure (on the left wing 18 or 98, on the right 81 or 89); in the middle of the costal area there is a pale patch and in the distal marginal area a row of ocellus-like spots. Sometimes, especially in the female, the red band of the forewing bearsa small white spot in the middle.

The red admiral is found in temperate regions of North Africa, North and Central America, Europe, Asia, and island regions of Hawaii, and the Caribbean.

In northern Europe, it is one of the last butterflies to be seen before winter sets in, often feeding on the flowers of ivy on sunny days. The red admiral is also known to hibernate, re-emerging individuals showing prominently darker colors than the first brood. The butterfly also flies on sunny winter days, especially in southern Europe.

In North America, the red admiral generally has two broods from March through October. Most of North America must be recolonized each spring by southern migrants, but the species overwinters in south Texas.

Male red admirals are territorial and perch during the afternoon until sunset. Larger territories are optimal and subject to intrusion by other males more frequently than smaller territories. Territories tend to be oval, 8–24 feet (2.4–7.3 m) long and 13–42 feet (4.0–12.8 m) wide. Males patrol their territory by flying around the perimeter between 7 and 30 times per hour. On average, territory holders interact with intruders 10 to 15 times per hour.


When another male encroaches on a red admiral's territory, the resident chases away the intruder, often in a vertical, helical path to disorient or tire out the intruder while minimizing the horizontal distance it travels from its perch. The red admiral immediately returns to its territory after chasing off encroaching males. Time spent patrolling increases as number of the intruder interactions increases.

Patrolling behavior is correlated with warmer air temperatures, so males begin patrolling early and continue later on warmer days. Overcast skies usually led to patrolling later in the day. It is not clear whether this later start time is due to lower air temperature or a direct effect of decreased solar radiation. Another theory is that males believe it is earlier in the morning on cloudy days because of the reduced solar radiation.

Mating usually occurs in late autumn or early winter following collective migration to southern regions with a warmer climate. The red admiral's main host plant, stinging nettle, is most abundant during this migration. Larval development proceeds through winter and adults are first sighted in early spring. The new generation of adults migrates north before mating, because food is usually diminished by late spring. In Europe, the cyclic nature of this migration has been confirmed by analysing stable isotopes of wing samples. In spring, individuals arriving at northern Europe (Kaliningrad) were of a southern origin, while in autumn the isotope analyses revealed that samples came from the surrounding area or northern latitudes. During migration, the red admiral flies at high altitudes where high-speed winds carry the butterfly, reducing energy expenditure.

11-10-2017 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)


Grey herons are the largest birds most of us ever see in our garden: the wing span is around 6ft.

Despite their size, they are surprisingly light, weighing on average only half as much as a greylag goose.

The old English name for a heron was hragra; other names now largely fallen into disuse include harn, hernser and hernshaw. Heron comes from the French, for the French name is héron céndre.

In medieval times the heron was a favourite quarry of falconers who valued its great flying skills and ability to evade the falcon's stoops.
Roast herons were also popular at medieval banquets: the young birds, called branchers, were thought to be the best to eat.
The fat of a heron killed at full moon was once believed to be a cure for rheumatism.


Herons are sociable birds when nesting, invariably nesting in long-established heronries.
Most heronries are in trees, with the majority of nests at least 25m above the ground. However, reed-bed heronries are not unusual, and they will also nest on cliffs, bushes, sometimes even on buildings of bridges.
Heronries can reach a prodigious size: one at Great Snowden's Wood, near Brede in Sussex, contained around 400 nests in 1866.
The biggest heronry in Britain is currently at Northward Hill in Kent, an RSPB reserve. Numbers here have peaked at over 200 nests, but the current total is around 150.
It's not unusual for a single tree to hold as many as 10 nests.
The annual count of heronries is the British Trust for Ornithology's longest running survey. The first took place in 1928.

It's quite normal for herons, disturbed at their nest, to regurgitate their last half-digested meal, an unpleasant experience for anyone unfortunate enough to be underneath the nest.

An increasing number of British heronries now also have little egrets nesting alongside the herons.

Herons are among the earliest nesters. It's not unusual for some birds to lay their first eggs in early February, though the normal start is early March, peaking at the end of the month.

11-10-2017 DEVESA, VALENCIA - KENTISH PLOVER (Charadrius alexandrinus)


The Kentish plover (Charadrius alexandrinus ) is a small cosmopolitan shorebird (40-44 g) of the family Charadriidae that breeds on the shores of saline lakes, lagoons, and coasts, populating sand dunes, marshes, semi-arid desert, and tundra. Both male and female birds have pale plumages with a white underside, grey/brown back, dark legs and a dark bill, however additionally the male birds also exhibit very dark incomplete breast bands, and dark markings either side of their head, therefore the Kentish plover is regarded as sexually dimorphic

Charadrius alexandrinus has a large geographical distribution, ranging from latitudes of 10º to 55º, occupying North Africa, both mainland, such as Senegal, and island, such as the Cape Verde archipelago, Central Asia, for example alkaline lakes in China, and Europe, including small populations in Spain and Austria. Some populations are migratory and often winter in Africa, whereas other populations, such as various island populations, do not migrate. Its common English name comes from the county of Kent, where it was once found, but it has not bred in Britain since 1979.


Kentish plovers are ground-nesting birds, often with a preference for low, open, moist nesting sites away from thick vegetation and human activity. They use a number of materials to build their nests, mainly consisting of shells, pebbles, grass and leaves in a small scrape in the ground. Like most plovers, the Kentish plovers are predominantly insectivores, feeding on a large range of arthropods and invertebrates depending on the environment, by using a run and stop method.

The Kentish plover is a small shorebird weighing around 40 g as an adult. Both male and female birds have black bills and dark legs, however adults have dimorphic plumage. During the breeding season, males have a black horizontal head bar, two incomplete dark breast-bands on each side of their breast, black ear coverts and a rufous nape and crown (although there is some variation between breeding populations), whereas the females are paler in these areas, without the dark markings. In the early breeding season, it is easy to distinguish between males and females since the ornaments are very pronounced, but as the breeding season progresses, the differences between the two sexes decrease. Moreover, males have longer tarsi and longer flank feathers than females. Longer flank feathers are thought to be an advantage for incubation and brood care, as the quality of feathers is associated with heat insulation.There are multiple significant predictors of plumage ornamentation in Kentish plovers. Firstly, the interaction between the advancement of the breeding season and rainfall seem to affect ornamentation. 


Male ornaments become more elaborated over the course of a breeding season in regions with high rainfall, whereas in regions with low rainfall, male ornaments become lighter. Secondly, the interaction between the breeding system and the sex can predict the degree of plumage ornamentation. In polygamous populations, the sexual ornaments are more pronounced, generating a stronger sexual dimorphism than in monogamous populations. The difference is especially witnessed in males, whereby the ornaments are darker and smaller in polygamous populations compared to monogamous populations, where males have lighter and larger ornaments. This is thought to be the result of a trade-off between the size and intensity of the ornaments.

Kentish plovers have an extremely wide geographical distribution and their habitats vary not just spatially but environmentally too. They are known to reside and breed in multiple types of habitat, from desert with ground temperatures reaching 50 °C to tundra. The distribution of this species’ breeding areas covers Europe, Asia and Africa,). In Europe, populations are typically found in the west; although there was once a breeding population in Hungary, Kentish plovers no longer breed there. In Africa, populations are found on the southern coast of Senegal and along the Northern coast of the Mediterranean, and the Red Sea coast. The breeding area continues along the Arabian Peninsula, Saudi Arabia, Qatar, and Bahrain in the Middle East. Small populations can be found on islands too, such as the Cape Verde archipelago, the Canary Islands, and the Azores. It is a rare vagrant in Australia. Some populations do not migrate, such as the Maio (Cape Verde) population, however other populations can migrate reasonable distances, for example, plovers that spend winter in North Africa have been known to migrate to Turkey and Greece in the spring. Some birds breeding in western Europe are not known to travel very far, just within Europe, however some do travel, mainly to Western Africa.

11-10-2017 DEVESA, VALENCIA - LITTLE STINT (Calidris minuta)


The Little Stint, scientifically known as Calidris minuta, is a diminutive wader, a member of the family Scolopacidae. It is recognized by its small stature, fine dark bill, and dark legs, which set it apart from other waders, save for its close relatives, the dark-legged stints. This species exhibits a fine bill tip, unwebbed toes, and a notable long primary projection.

In breeding plumage, the adult Little Stint can be identified by an orange hue on the breast, a stark white throat, and a pronounced white V on the back. Winter plumage makes identification more challenging, while juveniles can be spotted by their pale crown stripes and a faintly pinkish breast. The bird's call is a distinctive sharp "stit."


The Little Stint is found in arctic regions during the breeding season, favoring open, bare ground for nesting.

A true long-distance migrant, the Little Stint breeds in the arctic realms of Europe and Asia. When not breeding, it travels extensively to wintering grounds in Africa and south Asia. It has also been recorded as a vagrant in North America and Australia.

The Little Stint is known for its gregarious nature during the non-breeding season, often forming substantial flocks with other Calidris waders, particularly the Dunlin. These flocks are commonly seen on coastal mudflats or at the edges of inland pools.


Polygamous by nature, the Little Stint lays 3-5 eggs in a scrape on the ground. Both males and females may incubate separate clutches, a unique aspect of their breeding behavior.

The diet of the Little Stint consists of small invertebrates, which it picks off from the mud.

The Little Stint is currently listed as Least Concern by the IUCN, indicating that it is not at immediate risk of population decline. However, its numbers are influenced by the population dynamics of lemmings, which in turn affect predation rates by other Arctic species. The Little Stint is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

11-10-2017 ALBUFERA, VALENCIA - EURASIAN KESTREL (MALE) (Falco tinnunculus)


Small falcon with distinctive male plumage: gray head, rusty back, gray tail with broad black tip. Female is brownish above, with barring on the back, wings, and tail. Note rather pointed wingtips (unlike rounded wings of Accipiter hawks), and distinct dark spotting on the breast. Inhabits open and lightly wooded country, farmlands, grasslands, and heathlands; often seen over grassy areas beside roads and at airports. Perches on wires and posts, and typically hunts by hovering, at times fairly high overhead. Very similar to Lesser Kestrel.

11-10-2017 DEVESA, VALENCIA - CRESTED LARK (Galerida cristata)


The crested lark (Galerida cristata ) is a species of lark widespread across Eurasia and northern Africa. It is a non-migratory bird, but can occasionally be found as a vagrant in Great Britain.

A fairly small lark, the crested lark is roughly the same size as a Eurasian skylark, but shorter overall and bulkier around the head and body, and very similar in appearance, with a height of 17 cm (6.7 in) and a wingspan of 29 to 38 cm (11 to 15 in), weighing between 37 and 55 g (1.3 and 1.9 oz). It is a small, brown bird which has a short tail with light brown outer feathers. Male and females have no real differences, but young crested larks have more spots on their back than their older counterparts. Its plumage is downy but sparse and appears whitish. The distinct crest from which the crested lark gets its name is conspicuous at all times but is more pronounced during territorial or courtship displays and when singing. In flight it shows reddish underwings. It shares many characteristics with the Thekla lark, with the main distinctions between the two being the beak, the Thekla's heavier black-brown streaks and its grey underwing, present in European specimens.

11-10-2017 DEVESA, VALENCIA - BLACK NECKED GREBE (Podiceps nigricollis ssp. nigricollis)


The Black-necked Grebe, also known as the Eared Grebe (Podiceps nigricollis), is a striking member of the grebe family. It is characterized by its distinctive breeding plumage, which includes a black to blackish-brown head, neck, and breast, and ochre-colored feathers that fan out behind the eyes over the ear coverts. The flanks are a rich tawny rufous to maroon-chestnut, while the abdomen remains white. In non-breeding plumage, the bird sports greyish-black upper parts and a white or whitish body. Juveniles have a browner hue in their darker areas.

To identify the Black-necked Grebe, look for the red eye with a narrow yellow ring, the blackish line extending from the gape to the eye, and the thin, upturned black bill. The subspecies californicus typically has a longer bill, while P. n. gurneyi is smaller with a greyer head and lacks non-breeding plumage.

This species favors vegetated freshwater lakes for breeding and migrates to saline lakes and coastal estuaries post-breeding.

The Black-necked Grebe has a wide distribution, breeding across parts of Africa, Eurasia, and the Americas. It winters in locations such as the southwestern Palearctic, eastern parts of Africa and Asia, southern Africa, and as far south as Guatemala in the Americas.

11-10-2017 DEVESA, VALENCIA - DUNLIN (Calidris alpina)


The Dunlin, Calidris alpina, is a small wader, often seen bustling along shorelines with a characteristic "sewing machine" feeding action. In its breeding plumage, it is easily identified by its distinctive black belly patch, a feature unique among waders of similar size. Outside the breeding season, it adopts a more subdued grey and white plumage. Juveniles can be recognized by their brown feathers with whitish "V" shapes on the back.

Adult Dunlins in breeding attire sport a striking black belly that sets them apart from other waders. In winter, they turn grey above and white below. Look for the strong white wingbar in flight, and note the black legs and slightly down-curved bill. The bill, while appearing sharp in deceased specimens, is actually blunt at the tip in living birds, equipped with a sensitive probe for detecting invertebrates.

Dunlins favor coastal mudflats and sandy beaches, where they can be observed in large, sociable flocks, especially outside the breeding season.

This circumpolar species breeds in Arctic or subarctic regions. European and Asian populations are long-distance migrants, wintering as far south as Africa and the Middle East. North American populations tend to migrate shorter distances to coastal areas.


Dunlins exhibit strong philopatry, with individuals often returning to their natal areas to breed. They are highly gregarious in winter and can be seen in large flocks, sometimes performing synchronized aerial displays.

The Dunlin's call is a typical sandpiper "peep," while its display song is a harsh trill.

Nests are shallow ground scrapes lined with vegetation. Both parents incubate the typically four-egg clutch. Chicks are precocial but require brooding early on. Flight is achieved around three weeks, with the male providing most of the brood care post-hatching.

The Dunlin can be confused with other small waders, but its breeding plumage and feeding behavior are distinctive. Hybrids with the White-rumped Sandpiper and the Purple Sandpiper have been reported.

On breeding grounds, Dunlins primarily consume insects. During the rest of the year, their diet includes molluscs, worms, and crustaceans.

The Dunlin is classified as Least Concern by the IUCN, with a very large range and population size. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

10-10-2017 - VILLALONGA RESERVOIR, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


Cormorants live a long time, and some of the older cormorants would keep fishing even without the rings and tethers. Into the 20th century in Macedonia and Greece, fishermen used captive cormorants to herd fish toward their nets. Great Cormorants often hold the wings open when they are out of the water.

Behavior. Great Cormorants form flocks year-round, even in nesting areas, but they seldom gather in large flocks like Double-crested. They spend most of the day quietly perched out of the water, preening, stretching, and resting.

Cormorants are expert divers, with webbed feet, streamlined bodies, and feathers that hold water and reduce buoyancy. They are believed to dive to depths of 8 to 25 feet. After feeding, cormorants characteristically dry their feathers by perching with their wings outstretched.


The Cormorant is a large, black waterbird whose size and colour make it very visible. With a reptilian neck, it has an almost prehistoric appearance. It is often seen standing with its wings held out to dry.

Cormorants' short wings make them incredibly agile swimmers, and cormorants actually use less energy swimming than when flying. In fact, they have the highest flight cost of any flying bird. Some cormorants are also known for their ability to use rocks as tools to help them open the shells of prey they have captured.

The key to their adaptable nature might be their intelligence -- as evidenced by their ability to accurately count beyond the number seven.

The Cormorant is a large, black waterbird whose size and colour make it very visible. With a reptilian neck, it has an almost prehistoric appearance. It is often seen standing with its wings held out to dry. Cormorants are supreme fishers which can bring them into conflict with fisherman and has seen them persecuted in the past. The UK holds internationally significant wintering numbers of cormorants.

10-10-2017 - VILLALONGA RESERVOIR, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen, known scientifically as Gallinula chloropus, is a bird of the rail family, Rallidae. It is a bird of striking appearance, with a mix of black and brown plumage, a white under-tail, and white streaks along its flanks. Its legs are a vibrant yellow, and it sports a distinctive red frontal shield. The bill is a matching red with a yellow tip. Juveniles are a duller brown and do not have the red shield.

Adult moorhens can be identified by their red frontal shield, which has a rounded top and fairly parallel sides. The tailward margin of the red unfeathered area is smoothly curved. Their yellow legs and the combination of their black and brown plumage with white markings make them quite distinctive. The young are browner and lack the red shield, making them less conspicuous.

The common moorhen is found in a variety of wetland habitats, including marshes, ponds, canals, and lakes that are rich in vegetation. It is also known to inhabit city parks with suitable water bodies.

This species has a broad distribution across many parts of the Old World. It is not found in polar regions or many tropical rainforests but is otherwise widespread, often being the most common rail species in its range.

Moorhens are known for their secretive nature but can become quite tame in certain areas. They exhibit territorial behavior during the breeding season and are known to aggressively defend their territory against intruders.

10-10-2017 - VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)


The Green Sandpiper, Tringa ochropus, is a small wader, or shorebird, with a somewhat plump appearance. It boasts a dark greenish-brown back and wings, complemented by a greyish head and breast. The underparts are predominantly white, with the back featuring white spots that vary in extent depending on the season and age of the bird. The legs and short bill are a matching dark green, creating a harmonious color palette for this avian species.

When observing the Green Sandpiper, look for its distinctive flight pattern, which reveals dark wings above and below, punctuated by a striking white rump. This feature is a reliable identifier, setting it apart from its close relative, the slightly smaller Solitary Sandpiper of North America. Additionally, the Green Sandpiper's white-spotted back is most pronounced in breeding adults and less so in winter and juvenile plumage.


The Green Sandpiper is a freshwater aficionado, often found in more confined spaces than other waders, which typically prefer open vistas. It thrives in a variety of freshwater habitats, avoiding the more gregarious nature of some wader congregations.

This bird breeds across subarctic Europe and extends its range east across the Palearctic. It is migratory, seeking winter respite in southern Europe, the Indian Subcontinent, Southeast Asia, and tropical Africa.


The Green Sandpiper is not known for its sociability, as it is rarely seen in large groups. It prefers to forage alone, methodically picking small invertebrate prey from the mud along the edges of ponds and streams.

In flight, the Green Sandpiper emits a characteristic three-note whistle, which can be heard over the quiet waters it frequents.

A unique nester among waders, the Green Sandpiper lays 2 to 4 eggs in the abandoned arboreal nests of other bird species, such as the Fieldfare. The eggs incubate for approximately three weeks before hatching.

The Solitary Sandpiper (T. solitaria) is the Green Sandpiper's closest living relative and the most similar in appearance. However, the Solitary Sandpiper can be distinguished by its smaller size and different geographical range, being native to North America.

The diet of the Green Sandpiper consists of small invertebrates, which it diligently collects from the muddy edges of its freshwater habitat.

The IUCN classifies the Green Sandpiper as Least Concern, indicating a stable global population. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), ensuring concerted efforts for its conservation.

10-10-2017 - MONTE CORONA, VALENCIA - LANTANA PLUME MOTH (Lantanophaga pusillidactylus)


Lantanophaga pusillidactyla, the lantana plume moth, is a moth of the family Pterophoridae. It is native to the southern United States, Mexico, the Caribbean, and South America.

Other records include Cape Verde, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Réunion, South Africa, Madagascar, Mauritius, Nigeria, Seychelles, Eswatini, Tanzania, Zambia, Israel, Morocco, India, Indonesia (Java), New Guinea and Sri Lanka.

The wingspan is 11–14 mm.
Adults feed on flowers and lay eggs in flower heads. The larvae feed on Lantana camara, Lantana montevidensis, Lantana hispida, Lantana peduncularis, Lantana indica, Lantana involucrata, Lippia alba, Phyla nodiflora, Phyla lanceolata, Caperonia palustris, Mentha and Utricularia species.

10-10-2017 - MONTE CORONA, VALENCIA - SNAKE MILLIPEDE (Ommatoiulus rutilans)


Ommatoiulus rutilans
Ommatoiulus rutilans (C. L. Koch, 1847) Common name “Millipede”

Length 1.5 to 38mm.

Average lifespan 7 years

Widespread in Spain and into the mid, east and south of Europe.

Millipedes have an Omnivore diet, (both plant and animal matter are eaten) mainly feeding on detritus (decaying plant matter).
Diplopods (known scientifically as the class Diplopoda) are a class of myriads commonly known as “millipedes” (Latin name for a thousand feet) although the maximum number of legs on a millipede recorded does not exceed 750, ( The 750 record goes to the species named “Illacme plenipes”) most millipedes have less than 200.
Although millipedes are sometimes mistaken for their relatives, the centipede. Centipedes belong to a different class. Millipedes differ from them, mainly, in that almost all segments of the trunk have two pairs of legs, while centipedes have only one pair per segment.
Millipedes, are vulnerable to many kinds of predators. It does have a defence mechanism, by curling up rapidly into a spiral and also releasing a pungent smelling liquid. This deters many animals, so as to let the millipede go.
Millipedes are important recyclers because they return chemicals to the soil, for plants to use again. But for the gardener millipedes are mainly regarded as a pest.
The female usually lays her eggs concealed on the ground, in amongst or under decaying decomposing leaves and wood. The larvae will moult eight to twelve times before becoming adult. They will live under stones, rocks, fallen leaves and in crevasses of decaying wood. They can live in damp and arid areas, but cannot survive the dry atmosphere found inside many buildings.

10-10-2017 - MONTE CORONA, VALENCIA - COMMON BAGWORM MOTH (Psyche casta)



Psyche casta is a nocturnal moth from the family Psychidae, the bagworm moths. The wingspan of the males ranges from 12 to 15 millimeters. They have hairy, brown-metallic shiny wings. The grub-like females have legs but do not have wings and are yellowish or light brown, except for some dark brown back plates.
The host plants are from the groups: Poaceae, birch, willow, poplar and Vaccinium. The caterpillars make a protective hull from grass.

The flight time ranges from May to July.

7-10-2017 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN SERIN (FEMALE) (Serinus serinus)


When not breeding European serins are usually seen alone or in pares and also form flocks, sometimes mixed with other finches. They are active and often conspicuous birds. They spend their day walking or hopping on the ground in search of food. They also feed in trees and bushes. The song of European serins is a buzzing trill, very familiar in Mediterranean countries.

European serins are herbivores (granivores) and carnivores (insectivores). Their diet includes mainly seeds, buds, and flowers. During the breeding season, they mainly feed on insects.

European serins are monogamous and form pairs that may nest singly or in loose groups. Their breeding season takes place from February until early August. The female builds the nest in a shrub or tree and lays 3 to 5 eggs. The female incubates the eggs alone for 13-14 days but both parents care and feed the newly hatched chicks. The young start to fly when they are 15-18 days old and become independent 9-10 days later.

7-10-2017 PEGO MARJAL, ALICANTE - WHITE WAGTAIL (Motacilla alba)


The white wagtail (Motacilla alba) is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and the Asian Palearctic and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail or water wagtail (M. a. yarrellii) predominates; this is also called in Ireland willie wagtail, not to be confused with the Australian species Rhipidura leucophrys which bears the same common name. In total, there are between 9 and 11 subspecies of M. alba.

The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and human-made structures.


It is the national bird of Latvia and has featured on the stamps of several countries. Though it is 'of least concern', there are several threats against it, like being kept as pets and being used as food.

The white wagtail is a slender bird, 16.5 to 19 cm (6.5 to 7.5 in) in length (East Asian subspecies are longer, measuring up to 21 cm (8.3 in)), with the characteristic long, constantly wagging tail of its genus. Its average weight is 25 g (0.88 oz) and the maximum lifespan in the wild is about 12 years.


There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The pied wagtail, named for naturalist William Yarrell, exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some races show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish. Phylogenetic studies using mtDNA suggest that some morphological features have evolved more than once, including the back and chin colour. Breeding M. a. yarrellii look much like the nominate race except for the black back, and M. a. alboides of the Himalayas differs from the Central Asian M. a. personata only by its black back. M. a. personata has been recorded breeding in the Siddar Valley of Kashmir of the Western Himalayas. It has also been noted that both back and chin change colour during the pre-basic moult; all black-throated subspecies develop white chins and throats in winter and some black-backed birds are grey-backed in winter.


The call of the white wagtail is a sharp chisick, slightly softer than the version given by the pied wagtail. The song is more regular in white than pied, but with little territorial significance, since the male uses a series of contact calls to attract the female.

Worldwide distribution of the white wagtail. Yellow denotes summer range, green year round range, blue winter range.
This species breeds throughout Eurasia up to latitudes 75°N, only being absent in the Arctic from areas where the July isotherm is less than 4 °C. It also breeds in the mountains of Morocco and western Alaska. It occupies a wide range of habitats, but is absent from deserts. White wagtails are residents in the milder parts of its range such as western Europe and the Mediterranean, but migratory in much of the rest of its range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia.

The most conspicuous habit of this species is a near-constant tail wagging, a trait that has given the species, and indeed the genus, its common name. In spite of the ubiquity of this behaviour, the reasons for it are poorly understood. It has been suggested that it may flush prey, or signal submissiveness to other wagtails. A study in 2004 has suggested instead that it is a signal of vigilance to potential predators.

The exact composition of the diet of white wagtails varies by location, but terrestrial and aquatic insects and other small invertebrates form the major part of the diet. These range from beetles, dragonflies, small snails, spiders, worms, crustaceans, to maggots found in carcasses and, most importantly, flies. Small fish fry have also been recorded in the diet. The white wagtail is somewhat unusual in the parts of its range where it is non-migratory as it is an insectivorous bird that continues to feed on insects during the winter (most other insectivorous birds in temperate climates migrate or switch to more vegetable matter).

The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.

When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.


Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.

Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.

The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.


The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.

Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.


The Grey Heron can be confused with the larger North American Great Blue Heron or the South American Cocoi Heron. However, it can be distinguished by its size and the coloration of its flanks and thighs.

Grey Herons are apex predators within their ecosystem, feeding on a variety of aquatic creatures such as fish, amphibians, crustaceans, and insects. They have also been known to consume small mammals and juvenile birds.

The Grey Heron is classified as Least Concern by the IUCN, indicating a stable and widespread population.

7-10-2017 PEGO MARJAL, ALICANTE - 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.

8-10-2017 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus)


The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

When identifying the booted eagle, look for the white markings on the wings, often referred to as "landing lights," which are visible when the bird is in flight. The pale morph is dominant, but the darker morph can be more prevalent in certain eastern populations. The call of the booted eagle is a distinctive shrill "kli-kli-kli."

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.
