26-6-2024 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)

Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

The Common wall gecko is a small lizard native to the western Mediterranean area of North Africa and Europe. It is commonly observed on walls in urban environments, mainly in warm coastal areas. However, the Common wall gecko can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as insect hunter. This little creature is brownish-grey or brown in color with darker or lighter spots. These colors change in intensity according to the light. When geckos are active by day their color is darker than during the night.

Common wall geckos are mainly nocturnal or crepuscular. They may also be active during the day, on sunny days especially at the end of the winter. They like to receive sunlight near their refuge. They prefer to forage and spend their time singly; in the warmer months of the year, geckos can often be seen hunting nocturnal insects near light sources and street lamps.

26-6-2024 RACO DE OLLA, VALENCIA - MEDITERRANEAN GULL (JUVENILE) (ichthyaetus melanocephalus)


Formerly restricted to the Black Sea and the eastern Mediterranean this species has now expanded over most of Europe as far as Great Britain and Ireland, with 37 sites: 543–592 pairs in the United Kingdom in 2008. In Ireland breeding has been recorded in at least four counties. Breeding has also occurred in Belgium, the Netherlands, Denmark, Sweden, Estonia, Switzerland, the Czech Republic, Hungary and the Balkans.

In winter, this bird migrates to Mediterranean and Atlantic coasts.


The Mediterranean gull is slightly larger and bulkier than the black-headed gull with a heavier bill and longer, darker legs. The breeding plumage adult is a distinctive white gull, with a very pale grey mantle and wings with white primary feathers without black tips. The black hood extends down the nape and shows distinct white eye crescents. The blunt tipped, parallel sided, dark red bill has a black subterminal band. The non breeding adult is similar but the hood is reduced to an extensive dusky "bandit" mask through the eye. This bird takes two years to reach maturity. First year birds have a black terminal tail band and more black areas in the upperwings, but have pale underwings.

25-6-2024 MONTE CORONA, VALENCIA - SPIDERLING PLUME MOTH (Megalorhipida leucodactylus)


Megalorhipida leucodactyla is a species of moth of the family Pterophoridae that has a pantropical distribution.

The larvae have been recorded on a wide range of plants, including Boerhavia diffusa, Okenia hypogaea, Acacia neovernicosa, Amaranthus, Mimosa tenuiflora and Commicarpus tuberosus.

24-6-2026 MONTE CORONA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


 The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

25-6-2024 MONTE CORONA, VALENCIA - HALF EDGED WALL JUMPING SPIDER (Menemerus semilimbatus)


Menemerus semilimbatus is a spider in the family Salticidae.

Menemerus semilimbatus are about 6.5–8.4 millimetres (0.26–0.33 in) long, the male being slightly smaller than the female. These fairly big jumping spiders are dorso-ventrally flattened and are covered with short dense, grayish-white hairs, with hairy whitish palps and a white band on the side margins of the carapace, showing also a small white, triangular marking in the middle. The eyes are large and forward-facing.

The legs are light brown with darker rings and patches, while the abdomen is dorsally yellowish or grayish, with a characteristic pattern of several bright V-shaped markings. The females show a notch at the posterior edge of the epigyne and two oval depressions in the anterior half.


Menemerus semilimbatus is a Mediterranean species widely distributed in Europe, southern Asia and in Africa. In the Americas, it has been reported for Argentina, Chile, Ecuador and USA.

These spiders are synanthropic living in gardens and inside and on the outside of houses. It is usually found on the walls of buildings where it stalks its prey.

26-6-2024 LAGUNA DE SILLA, VALENCIA - BLACK WINGED STILT (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".

Adults are 33–36 cm (13–14 in) long, with long, pink legs, and a long, rather thin black bill. The birds are generally black above and white below, with a white head and neck (with a varying amount of black, species-dependent). Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year-round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter.[citation needed]

Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.


The breeding habitat of all these stilts is marshes, shallow lakes and ponds. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. In Europe, the black-winged stilt is a regular spring overshoot vagrant north of its normal range, occasionally remaining to breed in northern European countries. Pairs successfully bred in Britain in 1987, and after a 27-year hiatus there were two instances of successful breeding in Southern England in 2014. 13 young were fledged in southern England in 2017.Four chicks were successfully fledged in northern England in 2022; this is believed to be the most northerly breeding success for the black-winged stilt.

These birds pick up their food from sand or water. They eat mainly insects and crustaceans.

The nest site is a bare spot on the ground near water. These birds often nest in small groups, sometimes with avocets.

26-6-2024 RACO DE OLLA, VALENCIA - PIED AVOCET (JUVENILE) (Recurvirostra avosetta)

The pied avocet (Recurvirostra avosetta ) is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

The pied avocet is a striking white wader with bold black markings. Adults have white plumage except for a black cap and black patches in the wings and on the back. They have long, upturned bills and long, bluish legs. It is approximately 16.5–17.75 in (41.9–45.1 cm) in length of which the bill is approximately 2.95–3.35 in (7.5–8.5 cm) and the legs are approximately 3–4 in (7.6–10.2 cm). Its wingspan is approximately 30–31.5 in (76–80 cm). Males and females look alike. The juvenile resembles the adult but with more greyish and sepia tones.

The call of the avocet is a far-carrying, liquid, melodious kluit kluit.

These birds forage in shallow brackish water or on mud flats, often scything their bills from side to side in water (a feeding technique that is unique to the avocets). They mainly eat crustaceans and insects.

Their breeding habitat is shallow lakes with brackish water and exposed bare mud. They nest on open ground, often in small groups, sometimes with other waders. Three to five eggs are laid in a lined scrape or on a mound of vegetation.

26-6-2024 RACO DE OLLA, VALENCIA - COMMON SHELDUCK (MALE) (Tadorna tadorna)


The common shelduck (Tadorna tadorna ) is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb.

Fossil bones from Dorkovo (Bulgaria) described as Balcanas pliocaenica may actually belong to this species. More likely, they are an extinct species of Tadorna (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/Early Pleistocene).

The common shelduck resembles a small short-necked goose in size and shape. It is a striking bird, with a reddish-pink bill, pink feet, a white body with chestnut patches and a black belly, and a dark green head and neck. The wing coverts are white, the primary remiges black, and the secondaries green (only showing in flight) and chestnut. The underwings are almost entirely white. Sexes are similar, but the female is smaller, with some white facial markings, while the male is particularly crisply coloured in the breeding season, his bill bright red and bearing a prominent knob at the forehead.

Ducklings are white, with black cap, hindneck and wing and back patches. Juveniles are similarly coloured, greyish above and mostly white below, but already have the adult's wing pattern.

The call is a loud honk.

26-6-2024 RACO DE OLLA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)

The Black-headed gull (Chroicocephalus ridibundus) is a small and one of the most abundant gulls in much of Europe and Asia, and also in eastern Canada. It displays a variety of compelling behaviors and adaptations. Some of these include removing eggshells from one's nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity.

The summer adult has a chocolate-brown head (not black, although does look black from a distance), a pale grey body, black tips to the primary wing feathers, and a red bill and legs. The hood is lost in winter, leaving just two dark spots. Immature birds have a mottled pattern of brown spots over most of the body and a black band on the tail. There is no difference in plumage between the sexes. In flight, the white leading edge to the wing is a good field mark. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood.

Black-headed gulls breed in much of Europe, Asia, and in coastal eastern Canada. Most of their populations are migratory and winter further south, but some birds reside in the milder westernmost areas of Europe. Some Black-headed gulls also spend the winter in northeastern North America. They breed in large reed beds or marshes, or on islands in lakes, rivers, lagoons, deltas, and estuaries. They may also occur in ponds, canals, and flood lands, nesting on the heather moors, sand dunes, or beaches. During the winter these birds are found in estuaries with sandy or muddy beaches, ploughed fields, moist grasslands, reservoirs, urban parks, farmland, and gardens.

Black-headed gulls are highly gregarious birds, both when feeding or in evening roosts; they also breed in colonies. They are rarely seen at sea far from coasts. Black-headed gulls are active during the day and feed mainly by taking prey from the surface while swimming, or by dipping the head under the surface. They also walk along the coasts and probe for aquatic prey or catch flying insects on the wings. Black-headed birds are noisy, especially in colonies, with a familiar "kree-ar" call. When feeding they utter a sharp “kek-kek”.

26-6-2024 RACO DE OLLA, VALENCIA - GREATER FLAMINGO (Phoenicopterus roseus)


The Greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It was described by Peter Simon Pallas in 1811. The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.

Greater flamingos have an attractive coloration and appearance. Their feathers are pinkish/white, the wing coverts are red and the primary and secondary flight feathers are black. They have long pink bills with a black tip, yellow eyes and long pink legs. The male is bigger than the female, and juveniles have a gray-brown coloration, with some pink on their underparts, tail and wings, with the legs and beak being mainly brown.


The Greater flamingo inhabits Africa, the Middle East, southern Europe, and the Indian subcontinent. They occur in relatively shallow water bodies, such as saline lagoons, salt pans, large alkaline or saline lakes, and estuaries. Breeding takes place on sandbanks, mudflats, sandy or rocky islands, or open beaches.

Greater flamingos are very social. They travel in groups numbering up to thousands and they communicate by using visual and auditory cues. Greater flamingos are partially dispersive and migratory. They are traveling constantly, seeking areas with enough resources to sustain the whole flock, especially during the mating season. Greater flamingos keep their chicks together in crèches. Adults supervising crèches tend to act in a hostile way toward hatchlings if their own young are not in that crèche. Greater flamingos are diurnal, feeding during the day. Being bottom feeders, they rely on water levels that are low, and they move to new areas to find appropriate feeding conditions. They often bathe in fresh shallow water and preen their feathers to remove salt from them. They are not territorial birds but during breeding season they do defend their nests.



Greater flamingos are serially monogamous birds, forming pair bonds that remain together only for a single breeding season. They breed in dense colonies numbering up to 20,000 or more pairs. They perform spectacular group displays of courtship, involving ritualized preening, synchronized wing-raising, and head-flagging, where they raise their necks and beaks and turn their heads from side to side. Breeding seasons vary with location, occurring in some areas at irregular intervals, following the rains. Nest-building is done in pairs. A single chalky-white egg is laid, rarely two. Both parents share the incubation of 27-31 days. After several days of being brooded by both parents, the chick joins a crèche with many other chicks. Both parents feed the chick, with the typical milk that is secreted in the adults' upper digestive tract. Chicks fledge between 65 and 90 days after hatching and become reproductively mature between 4 and 6 years of age.

Greater flamingos are threatened by human disturbance and lowering water levels, which increases the salinity of sites where they feed and so can affect food resources, or cause thick soda deposits which can harm the legs of chicks. The potential effects of climate change on rainfall and sea level may therefore impact breeding sites seriously in the future. Further threats to greater flamingos include disease, pollution, lead poisoning (from the ingesting of lead shot), and habitat loss as a result of industrial and harbor development or drainage of the wetlands for agriculture. Large numbers of greater flamingos in Egypt are shot or captured for sale in markets, and the collection of eggs remains a threat in some areas, such as Algeria.

26-6-2024 RACO DE OLLA, VALENCIA - LARGE PSAMMODROMUS LIZARD (Psammodromus algirus)

Psammodromus algirus, known commonly as the Algerian psammodromus or the large psammodromus, is a species of lizard in the family Lacertidae. The species is found in southwestern Europe and northwestern Africa.

Subspecies

There are four subspecies:

Psammodromus algirus algirus (Linnaeus, 1758)

Psammodromus algirus doriae Bedriaga, 1886

Psammodromus algirus nollii Fischer, 1887

Psammodromus algirus ketamensis Galán, 1931

Geographic range

Psammodromus algirus is found in North Africa (Morocco, Algeria, and Tunisia) and in Southwestern Europe (Iberian Peninsula: Portugal, Spain, Andorra, Gibraltar; southernmost France, and Italy near Lampedusa).

The IUCN assessment from 2009 treats Psammodromus algirus nollii and Psammodromus algirus ketamensis as full species and restricts Psammodromus algirus to North Africa.

P. algirus typically occurs in dense bushy vegetation, but it can also venture to more open areas. It can be found at at elevations up to 2,600 m (8,500 ft) above sea level, but it is more common at lower elevations.

Psammodromus algirus mainly feeds on terrestrial arthropods, specifically Orthoptera, Formicidae, Coleoptera, Hemiptera, and Araneae.

P. algirus is threatened by habitat loss.

P. algirus commonly reaches a snout–vent length of about 7.5 cm (3.0 in), occasionally 9 cm (3.5 in). The tail is 2–3 times the body length. Dorsal colouration is usually metallic brownish with a pair of conspicuous white or yellowish stripes on both sides.

26-6-2024 RACO DE OLLA, VALENCIA - SANDWICH TERN (JUVENILE)(Thalasseus sandvicensis)

The Sandwich tern (Thalasseus sandvicensis ) is a tern in the family Laridae. It is very closely related to the lesser crested tern (T. bengalensis ), Chinese crested tern (T. bernsteini ), Cabot's tern (T. acuflavidus ), and elegant tern (T. elegans ) and has been known to interbreed with the lesser crested. It breeds in the Palearctic from Europe to the Caspian Sea wintering to South Africa, India and Sri Lanka.

The Sandwich tern is a medium-large tern with grey upperparts, white underparts, a yellow-tipped black bill and a shaggy black crest which becomes less extensive in winter with a white crown. Young birds bear grey and brown scalloped plumage on their backs and wings. It is a vocal bird. It nests in a ground scrape and lays one to three eggs.

Like all Thalasseus terns, the Sandwich tern feeds by plunge diving for fish, usually in marine environments, and the offering of fish by the male to the female is part of the courtship display.

Like all Thalasseus terns, the Sandwich tern feeds by plunge diving for fish, usually in marine environments, and the offering of fish by the male to the female is part of the courtship display.

This is a medium-large tern, 37–43 cm (15–17 in) long with an 85–97 cm (33–38 in) wingspan, which is unlikely to be confused within most of its range, although the South American race could be confused with the elegant tern. The Sandwich tern's weight ranges from 180-300 g (6.3-10.6 oz).

The Sandwich tern's thin sharp bill is black with a yellow tip, except in the yellow or orange billed South American race. Its short legs are black. Its upperwings are pale grey and its underparts white, and this tern looks very pale in flight, although the primary flight feathers darken during the summer.

The lesser crested tern and elegant tern differ in having all-orange bills; lesser crested also differs in having a grey rump and marginally stouter bill, and elegant in having a slightly longer, more slender bill. The Chinese crested tern is the most similar to the Sandwich tern, but has a reversal of the bill colour, yellow with a black tip; it does not overlap in range with the Sandwich tern so confusion is unlikely.

In winter, the adult Sandwich tern's forehead becomes white. Juvenile Sandwich terns have dark tips to their tails, and a scaly appearance on their back and wings, like juvenile roseate terns.

The Sandwich tern is a vocal bird; its call is a characteristic loud grating kear-ik or kerr ink.

26-6-2024 RACO DE OLLA, VALENCIA - COMMON TERN (Sterna hirundo)

The Common tern (Sterna hirundo) is a seabird that has a circumpolar distribution. it has four subspecies breeding in temperate and subarctic regions of Europe, Asia, and North America. Its large population and huge breeding range mean that this species is classed as being of least concern, although numbers in North America have declined sharply in recent decades.

Known for its attractive plumage and graceful flight, Common terns have a slender body and a smoothly rounded head, and long pointed wings. Their breeding plumage is light silvery-gray upperparts and clear black outer primaries on its wingtips. Outside the breeding season, the birds keep some of their distinguishable black cap, but their forehead and face turn white. Their legs and bill turn black, losing their orange-red coloration. Male and female are similar in appearance throughout the year. Juvenile Common terns have pale grey upper wings with a dark carpal bar. The crown and nape are brown, and the forehead is ginger, wearing to white by autumn. The upper parts are ginger with brown and white scaling, and the tail lacks the adult's long outer feathers. Birds in their first post-juvenile plumage, which normally remain in their wintering areas, resemble the non-breeding adult but have a duskier crown, dark carpal bar, and often very worn plumage. By their second year, most young terns are either indistinguishable from adults, or show only minor differences such as a darker bill or white forehead.

Common terns occur from northern Canada to the Caribbean Sea in the south, throughout Europe, Northern Asia, the Middle East and North Africa. Outside of the mating season, these birds winter along the coasts of South America and Central America, along Africa’s coast and the Arabian Peninsula, as well as on islands in the Indian Ocean and throughout Australasia and much of Southeast Asia. They breed on sand spits, beaches and low-lying inshore islands. They also nest inland near slow-flowing rivers, and lakes in open country. This species favors areas that have close shallow waters where they can fish. During migration, they are mainly seen along coasts, at freshwater inland lakes and in estuaries. During winter, they are mostly coastal, in warm tropical and subtropical waters.

Common terns are diurnal birds and they live in colonies with no clear hierarchy among them, with all seeming to be equal. Although Common terns all migrate and live together, the family unit is responsible to feed and care for its own eggs and chicks, and individuals will often defend feeding territories. This species forages by flying above water and hovering, often plunge-diving to catch prey under the surface. It will also swim as it picks up food from the surface of the water or just below it. A highly migratory bird, it leaves the breeding grounds for the wintering sites typically from August to October, soon after all the chicks fledge. These birds communicate mostly by means of their unusual, hoarse voices, having three different and distinct calls. Communication during mating is mainly visual and/or tactile.

Common terns are monogamous, which means they mate with only one partner during a breeding season. At the time of courtship, which starts in April, males establish their territories within the colony before commencing what is known as "courtship feeding," where a male brings a fish to a female to court her. Courtship displays include the male posturing followed by the pair circling each other. Eggs are laid from April to June. Common terns usually breed in huge colonies, though there may be some isolated pairs. Both parents construct their nest on bare ground, sometimes with low vegetation surrounding it or on dead floating vegetation. 2-3 eggs are laid and are incubated by both parents for 21-25 days. Chicks leave their nest after several days, but remain nearby and their parents still feed them. They fledge at around 22-28 days old, remaining in the family group for at least another two months. Common terns become reproductively mature at 3 years of age.

26-6-2024 RACO DE OLLA, VALENCIA - COMMON TERN (JUVENILE) (Sterna hirundo)


The Common tern (Sterna hirundo) is a seabird that has a circumpolar distribution. it has four subspecies breeding in temperate and subarctic regions of Europe, Asia, and North America. Its large population and huge breeding range mean that this species is classed as being of least concern, although numbers in North America have declined sharply in recent decades.

Known for its attractive plumage and graceful flight, Common terns have a slender body and a smoothly rounded head, and long pointed wings. Their breeding plumage is light silvery-gray upperparts and clear black outer primaries on its wingtips. Outside the breeding season, the birds keep some of their distinguishable black cap, but their forehead and face turn white. Their legs and bill turn black, losing their orange-red coloration. Male and female are similar in appearance throughout the year. Juvenile Common terns have pale grey upper wings with a dark carpal bar. The crown and nape are brown, and the forehead is ginger, wearing to white by autumn. The upper parts are ginger with brown and white scaling, and the tail lacks the adult's long outer feathers. Birds in their first post-juvenile plumage, which normally remain in their wintering areas, resemble the non-breeding adult but have a duskier crown, dark carpal bar, and often very worn plumage. By their second year, most young terns are either indistinguishable from adults, or show only minor differences such as a darker bill or white forehead.

15-8-1984 AMBOSELI, KENYA - SOUTHERN LION (FEMALE) (Panthera leo ssp. melanochaita)


The Southern lion is a lion subspecies from Southern and East Africa. In this region, lion populations were referred to by several regional names, including Katanga lion, Transvaal lion, Kalahari lion, Southeast African lion, Southwest African lion, Masai lion, Serengeti lion, Tsavo lion, and Uganda lion. It has also been referred to as 'Eastern-Southern African lion', 'Southern lion', and as 'southern subspecies'.

The fur of Southern lions varies in color from light buff to dark brown. They have rounded ears and a black tail tuft. Mane color varies from sandy, tawny, isabelline, and light reddish yellow to dark brown and black. Mane length varies from short to extending to knee joints and under the belly. Lions without a mane were observed in the Tsavo area. Mane development is related to age: older males have more extensive manes than younger ones; manes continue to grow up to the age of four to five years, long after lions become reproductively mature. Males living in the Kenyan highlands develop heavier manes than lions in the more humid and warmer lowlands of eastern and northern Kenya. White lions have occasionally been encountered in and around South Africa's Kruger National Park and the adjacent Timbavati Private Game Reserve. Their whitish fur is a rare morph caused by a double recessive allele. It has normal pigmentation in the eyes and skin. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool.

25-6-2024 MONTE CORONA, VALENCIA - GRASS CRAB SPIDER (Runcinia grammica)


Runcinia grammica (sometimes also referred to as Runcinia lateralis) is a species of spiders of the genus Runcinia, with a distribution of "Europa, Near East to Iran, Russia, Central Asia, China, Japan. Introduced to St. Helena, South Africa."

The species generally lives in peat bogs, fens, and meadows, although it has also been known to inhabit urban areas They usually mature to adulthood in the summer. They have short, broad bodies, which are covered in hair and spines. They have clear muscular corrugation on their sides, and, on small raised bumps on their heads, eight small eyes. Males are usually 2.5–3.5mm in length, females 4-6mm. They are predators, and eat various species of insects.

Unlike many spiders, they do not spin a web of any kind. Instead, they prowl on the ground, as well as climbing plants and flowers, to find their prey. They can move forwards, backwards, and sideways.

Runcina grammica has reportedly been sighted in various areas of Southeastern Spain and Southwestern Portugal. They are also known to inhabit Armenia, Georgia, Azerbaijan, Caucasus, Italy, India, South Africa, St. Helena, Turkey, France, and in the Carpathian Basin. They are among the most common species of spiders in Portugal. They are one of the many species preserved at the Mountain Zebra National Park, in South Africa.

24-6-2026 PEGO MARJAL, ALICANTE - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)


Rithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red. The prothorax is violet with slightly darker longitudinal stripes. The membranous wings have distinctive red veins, the pterostigma is orange-brown and there is a large orange-brown splash at the base of the hind wings. The abdomen is fairly broad and is pinkish-violet, with purple markings on the top of each segment and blackish markings on the terminal three segments. Females are a similar size to males but the thorax is brownish and the abdomen is yellow with dark brown markings. The wings of females lack the red veins of males but have similar orange-brown patches. It is very similar in appearance to the red-veined dropwing (Trithemis arteriosa), but that species has a more slender abdomen and a wedge-shaped black area on either side of the tip of the abdomen.

24-6-2026 PEGO MARJAL, ALICANTE - PLAIN TIGER BUTTERFLY (Danaus chrysippus)

Danaus chrysippus, also known as the plain tiger, African queen, or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae. Danainae primarily consume plants in the genus Asclepias, more commonly called milkweed. Milkweed contains toxic compounds, cardenolides, which are often consumed and stored by many butterflies. Because of their emetic properties, the plain tiger is unpalatable to most predators. As a result, its coloration is widely mimicked by other species of butterflies. The plain tiger inhabits a wide variety of habitats, although it is less likely to thrive in jungle-like conditions and is most often found in drier, wide-open areas.

24-6-2026 PEGO MARJAL, ALICANTE - BARN SWALLOW (Hirundo rustica)

The Barn swallow (Hirundo rustica) is the most widespread species of swallow in the world. In fact, it has the largest natural distribution of any of the world's passerines, ranging over 251 million square kilometers globally. In Anglophone Europe it is just called the swallow; in northern Europe, it is the only common species called a "swallow" rather than a "martin".

The Barn swallow is a distinctive songbird with blue upperparts and a long, deeply forked tail. There is a line of white spots across the outer end of the upper tail. The female is similar in appearance to the male, but the tail streamers are shorter, the blue of the upperparts and breast band is less glossy, and the underparts paler. The juvenile is browner and has a paler rufous face and whiter underparts. It also lacks the long tail streamers of the adult.

Barn swallows are found in Europe, Asia, Africa, and the Americas. These birds are long-distance migrants and their wintering grounds cover much of the Southern Hemisphere as far south as central Argentina, the Cape Province of South Africa, and northern Australia. 

The preferred habitat of Barn swallows is open country with low vegetation, such as pasture, meadows, and farmland, preferably with nearby water. These birds avoid heavily wooded or precipitous areas and densely built-up locations. On their wintering grounds, Barn swallows avoid only dense forests and deserts. They are most common in open, low vegetation habitats, such as savanna and ranch land, and in Venezuela, South Africa, and Trinidad and Tobago the birds are particularly attracted to burnt or harvested sugarcane fields and the waste from the cane.

Barn swallows are gregarious birds and in the absence of suitable roost sites, they sometimes roost on wires where they are more exposed to predators. Individual birds tend to return to the same wintering locality each year and congregate from a large area to roost in reed beds. These roosts can be extremely large and are thought to be a protection from predators. Barn swallows typically feed by day in open areas 7-8 m (23-26 ft) above shallow water or the ground often following animals, humans, or farm machinery to catch disturbed insects; they may also pick prey items from the water surface, walls, and plants. During the breeding, season Barn swallows hunt in pairs, but otherwise form often large flocks. These birds are usually fairly quiet on the wintering grounds. At other times they communicate with constant twittering and chattering. The song of the male Barn swallow is a cheerful warble, often ending with 'su-seer'. Other calls include 'witt' or 'witt-witt' and a loud 'splee-plink' when excited (or trying to chase intruders away from the nest). The alarm calls include a sharp 'siflitt' for predators like cats and a 'flitt-flitt' for birds of prey like the hobby.

24-6-2026 MONTE CORONA, VALENCIA - MADAGASCAN PALM (Pachypodium lamerei)

Pachypodium lamerei is a species of flowering plant in the family Apocynaceae. It is a stem succulent, photosynthesizing mainly through its trunk, and comes from the island of Madagascar, off the east coast of Africa. It has large thorns and leaves mostly just at the top of the plant, and large, fragrant flowers. The species has become one of the best known pachypodiums in cultivation, being relatively easy to propagate and grow. In cultivation it is often marketed as the Madagascar palm, despite its not being a palm at all. A variety called "Ramosum" has been described. It is distinguished mostly by a dwarf growth habit and its more rounded corolla lobe.

Pachypodium lamerei has a tall, silvery-gray trunk covered with sharp 6.25 cm spines. Long, narrow leaves grow only at the top of the trunk, like a palm tree. It rarely branches. Plants grown outdoors will reach up to 6 m (20 ft), but when grown indoors it will slowly reach 1.2–1.8 m (3.9–5.9 ft) tall.

Plants grown outdoors develop large, white, fragrant flowers at the top of the plant. They rarely flower indoors.

Pachypodium lamerei grows best in warm climates and full sun. It will not tolerate hard frosts, and will likely drop most of its leaves if exposed to even a light frost. It is easy to grow as a houseplant, if you can provide the sunlight it needs. Use a fast-draining potting mix, such as a cactus mix and pot in a container with drainage holes to prevent root rot.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.

22-6-2024 MONTE CORONA, VALENCIA - COMMON CREVICE CRICKET (Gryllomorpha dalmatina)


Gryllomorpha dalmatina, common name wingless house-cricket, is a species of cricket belonging to the family Gryllidae subfamily Gryllomorphinae.

This cricket is mainly present in France, Italy, Slovenia, Spain, Switzerland, in the Near East and in North Africa.

Gryllomorpha dalmatina is the largest species of the genus Gryllomorpha. The adults grow up to 15–20 millimetres (0.59–0.79 in). They are wingless. The basic coloration of the body is pale brown, with dark-brown markings on the body and the legs. The antennae are very long. Also legs are rather long. The female ovipositor is long and thin and can reach a length of about 12–17 millimetres (0.47–0.67 in).

They can commonly be encountered in nature from April through early Autumn, but in the domestic environment they are active all year round. They can be found in buildings, especially in dark moist places, as caves, cellars, basements, but also under stones and bark.  As a matter of fact, these crickets fear the light and feed on organic debris.
