6-8-2023 POBLA DE DUC, 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; in addition 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.


6-8-2023 LLUTXENT, VALENCIA - COMMON HOUSE MARTIN (Delichon urbicum)

The western house martin (Delichon urbicum), sometimes called the common house martin, northern house martin or, particularly in Europe, just house martin, is a migratory passerine bird of the swallow family which breeds in Europe, north Africa and across the Palearctic; and winters in sub-Saharan Africa and tropical Asia. It feeds on insects which are caught in flight, and it migrates to climates where flying insects are plentiful. It has a blue head and upperparts, white rump and pure white underparts, and is found in both open country and near human habitation. It is similar in appearance to the two other martin species of the genus Delichon, which are both endemic to eastern and southern Asia. It has two accepted subspecies.

Both the scientific and colloquial name of the bird are related to its use of human-made structures. It builds a closed cup nest from mud pellets under eaves or similar locations on buildings usually in colonies.

It is hunted by the Eurasian hobby (Falco subbuteo), and like other birds is affected by internal parasites and external fleas and mites, although its large range and population mean that it is not threatened globally.

The western house martin breeds across temperate Eurosiberia east to central Mongolia and the Yenisei River, and in Morocco, Tunisia and northern Algeria, and migrates on a broad front to winter in sub-Saharan Africa.

The preferred habitat of the western house martin is open country with low vegetation, such as pasture, meadows and farmland, and preferably near water, although it is also found in mountains up to at least 2,200 m (7,200 ft) elevation. It is much more urban than the barn swallow, and will nest even in city centres if the air is clean enough. It is more likely to be found near trees than other Eurasian swallows, since they provide insect food and also roosting sites. This species does not normally use the reed-bed roosts favoured by migrating barn swallows.

It uses similar open habitats on the wintering grounds, but the western house martin is less conspicuous than wintering barn swallows, tending to fly higher and be more nomadic. In the tropical parts of its wintering range, like East Africa, it appears to be mainly found in the higher areas.

5-8-2023 ADOR CAMPO, VALENCIA - VIOLET DROPWING DRAGONFLY (MALE)

Trithemis annulata is an adaptable species, and the adults are able to tolerate a range of habitats including semi-arid rangeland. They can be seen flying near sluggish rivers, in marshes and also beside still-water ponds. They are sometimes seen in brackish water habitats, although it is unclear whether they actually breed in salty water. The larvae develop rapidly, so these dragonflies are able to make use of temporary water bodies for breeding. Males are often to be seen perching on the twigs of waterside shrubs and on rocks in the sunshine, but in the evening or when the sun is obscured, they move into trees.

The female T. annulata is thought to deposit her eggs by flying over the surface and dipping the tip of her abdomen in the water. The larvae develop in water where they are aggressive predators. The adults are also predators, using their excellent eyesight to detect prey and their legs to hold and carry their victims.


 

5-8-2023 POTRIES, VALENCIA - WHITE FEATHERLEG DAMSELFLY (Platycnemis latipes)

The white-legged damselfly or blue featherleg is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range.


 

5-8-2023 ADOR CAMPO, VALENCIA - ORANGE WINGED DROPWING DRAGONFLY (MALE) (Trithemis kirbyi)

Trithemis kirbyi, also known as the Kirby's dropwing, orange-winged dropwing, or scarlet rock glider is a species of dragonfly in the family Libellulidae.

 It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Chad, Comoros, the Democratic Republic of the Congo, Ivory Coast, Egypt, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Madagascar, Malawi, Morocco, Mozambique, Namibia, Nigeria, Senegal, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Western Sahara, Zambia, Zimbabwe, and possibly Burundi. It is also present in southern Europe, the Arabian Peninsula, the Indian Ocean Islands and South Asia to India.

Since 2003 this African tropical dragonfly has been colonizing Europe helped by a widespread increase in temperatures. It is now breeding successfully in Spain, Portugal and France.


5-8-2023 ADOR CAMPO, VALENCIA - VIOLET DROPWING DRAGONFLY (FEMALE)

Trithemis annulata, known commonly as the violet dropwing, violet-marked darter, purple-blushed darter or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, in the Middle East, in the Arabian Peninsula and southern Europe. These insects are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings while females are yellow and brown. Both sexes have red eyes.

Trithemis annulata is found in most of Africa and also in France, Cyprus, Greece, India, Iran, Iraq, Israel, Italy, Jordan, Kuwait, Lebanon, Mauritius, Oman, Portugal, Qatar, Réunion, Syria, Turkey, United Arab Emirates and Yemen. It was also recorded in the Maltese islands in 2005 and found breeding there in 2007. With the advent of global warming, it is increasing its range northwards in Europe and in the late 1990s advanced from southern Spain and southern Italy into France, and from Greece and Turkey into Central Europe. One such place where it has become established is the floodplain of the River Ebro in northeastern Spain.


 

5-8-2023 ADOR CAMPO, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)


 Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

24-5-2023 SUKAU RIVER LODGE, BORNEO - ORIENTAL PIED HORNBILL (Anthracoceros albirostris) (COURTESY OF MRS VALERIE FISHER)

The oriental pied hornbill (Anthracoceros albirostris) is an Indo-Malayan pied hornbill, a large canopy-dwelling bird belonging to the family Bucerotidae. Two other common names for this species are Sunda pied hornbill (convexus) and Malaysian pied hornbill.

The species is considered to be among the smallest and most common of the Asian hornbills. It has the largest distribution in the genus and is found in the Indian Subcontinent and throughout Southeast Asia. Its natural habitat is subtropical or tropical moist lowland forests. The oriental pied hornbill's diet includes fruit, insects, shellfish, small reptiles and, sometimes, small mammals and birds including their eggs.




 

23-5-2023 SUKAU RIVER LODGE, BORNEO - BORNEAN ORANGUTAN (Pongo pygmaeus) COURTESY OF MRS VALERIE FISHER


 The name orangutan means "man of the forest" in the Malay language. In the lowland forests in which they reside, orangutans live solitary existences. They feast on wild fruits like lychees, mangosteens, and figs, and slurp water from holes in trees. They make nests in trees of vegetation to sleep at night and rest during the day. Adult male orangutans can weigh up to 200 pounds. Flanged males have prominent cheek pads called flanges and a throat sac used to make loud verbalizations called long calls. An unflanged male looks like an adult female. In a biological phenomenon unique among primates, an unflanged male can change to a flanged male for reasons that are not yet fully understood.

1-8-2023 MUNTANYETA DEL SANS, ALBUFERA - LITTLE EGRET (Egretta garzetta)

The adult little egret is 55–65 cm (22–26 in) long with an 88–106 cm (35–42 in) wingspan, and weighs 350–550 g (12–19 oz). Its plumage 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. There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.



1-8-2023 ULLAL DE BALDOVI, ALBUFERA - SQUACCO HERON (Ardeola ralloides)

The squacco heron (Ardeola ralloides) is a small heron, 44–47 cm (17+1⁄2–18+1⁄2 in) long, of which the body is 20–23 cm (8–9 in), with 80–92 cm (31+1⁄2–36 in) wingspan. It is of Old World origins, breeding in southern Europe and the Greater Middle East.

The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

The Squacco Heron uses freshwater localities throughout Europe and the Middle East as breeding grounds to later migrate south to the Sub-Saharan African region. Non-breeding Squacco Herons share similar traits with other heron species like the Indian Pond Heron and Malagasy Pond Heron which show tawny color plumage, lighter streaking, smaller bill, and narrower wing tips.


1-8-2023 MUNTANYETA DEL SANS, ALBUFERA - WHISKERED TERN (Chlidonias niger)

The whiskered tern (Chlidonias hybrida) is a tern in the family Laridae. The genus name is from Ancient Greek khelidonios, "swallow-like", from khelidon, "swallow". The specific hybridus is Latin for hybrid; Peter Simon Pallas thought it might be a hybrid of white-winged black tern and common tern, writing "Sterna fissipes [Chlidonias leucopterus] et Hirundine [Sterna hirundo] natam".

This bird has a number of geographical races, differing mainly in size and minor plumage details.

C. h. hybrida breeds in warmer parts of Europe and the Palearctic (northwestern Africa and central and southern Europe to southeastern Siberia, eastern China and south to Pakistan and northern India). The smaller-billed and darker C. h. delalandii is found in east and south Africa, and the paler C. h. javanicus from Java to Australia.

The tropical forms are resident, but European and Asian birds winter south to Africa and the Indian Subcontinent. A tagged whiskered tern was spotted at Manakudi Bird Sanctuary, Kanniyakumari District of Tamil Nadu, India in the month of April 2021.

This species breeds in colonies on inland marshes, sometimes amongst black-headed gulls, which provide some protection. The scientific name arises from the fact that this, the largest marsh tern, show similarities in appearance to both the white Sterna terns and to black tern.


 

1-8-2023 ULLAL DE BALDOVI, ALBUFERA - SMALL WHITE BUTTERFLY (Pieris rapae)

Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, New Zealand, and Australia, as a result of accidental introductions. 

1-8-2023 ULLAL DE BALDOVI, ALBUFERA - NOMAD DRAGONFLY (FEMALE) (Sympetrum fonscolombii)

The red-veined darter or nomad(Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.

Sympetrum fonscolombii is a widespread and common species in much of central and southern Europe including most Mediterranean islands, North Africa, the Middle East, Mongolia, south-western Asia, including the Indian Subcontinent, the Indian Ocean Islands and Sri Lanka. In Europe it is resident in the south of its range but in some years it migrates northward. From the 1990s onwards has increasingly been found in northwest Europe, including Belgium, Sweden, Finland, Poland, Britain and Ireland. It is the only Libellulidae to be found in the Azores and it is also found on the Canary Islands and Madeira. 

1-8-2023 MUNTANYETA DEL SANS, ALBUFERA - BLACK CROWNED NIGHT HERON (Nycticorax nycticorax)


The black-crowned night-heron (Nycticorax nycticorax), or black-capped night-heron, commonly shortened to just night-heron in Eurasia, is a medium-sized heron found throughout a large part of the world, including parts of Europe, Asia, and North and South America. In Australasia it is replaced by the closely related nankeen night-heron (N. caledonicus), with which it has hybridized in the area of contact.


Adults have a black crown and back with the remainder of the body white or grey, red eyes, and short yellow legs. They have pale grey wings and white under parts. Two or three long white plumes, erected in greeting and courtship displays, extend from the back of the head. The sexes are similar in appearance although the males are slightly larger. Black-crowned night-herons do not fit the typical body form of the heron family. They are relatively stocky with shorter bills, legs, and necks than their more familiar cousins, the egrets and "day" herons. Their resting posture is normally somewhat hunched but when hunting they extend their necks and look more like other wading birds.

Immature birds have dull grey-brown plumage on their heads, wings, and backs, with numerous pale spots. Their underparts are paler and streaked with brown. The young birds have orange eyes and duller yellowish-green legs. They are very noisy birds in their nesting colonies, with calls that are commonly transcribed as quok or woc.


The breeding habitat is fresh and salt-water wetlands throughout much of the world. The subspecies N. n. hoactli breeds in North and South America from Canada as far south as northern Argentina and Chile, N. n. obscurus in southernmost South America, N. n. falklandicus in the Falkland Islands, and the nominate race N. n. nycticorax in Europe, Asia and Africa. Black-crowned night-herons nest in colonies on platforms of sticks in a group of trees, or on the ground in protected locations such as islands or reedbeds. Three to eight eggs are laid.

This heron is migratory in the northernmost part of its range, but otherwise resident (even in the cold Patagonia). The North American population winters in Mexico, the southern United States, Central America, and the West Indies, and the Old World birds winter in tropical Africa and southern Asia.

A colony of the herons has regularly summered at the National Zoo in Washington, D.C. for more than a century. The birds also prominently live year-round in the shores around the San Francisco Bay, with the largest rookery in Oakland. Their ever presence at Oakland's Lake Merritt and throughout the city's downtown area, as well as their resilience to the urban environment and displacement efforts, have led to them being named Oakland's official city bird.


These birds stand still at the water's edge and wait to ambush prey, mainly at night or early morning. They primarily eat small fish, leeches, earthworms, mussels, squid, crustaceans (such as crayfish), frogs, other amphibians, aquatic insects, terrestrial insects, lizards, snakes, small mammals (such as rodents), small birds, eggs, carrion, plant material, and garbage and refuse at landfills. They are among the seven heron species observed to engage in bait fishing; luring or distracting fish by tossing edible or inedible buoyant objects into water within their striking range – a rare example of tool use among birds. During the day they rest in trees or bushes. N. n. hoactli is more gregarious outside the breeding season than the nominate race.

Idaea eugeniata algeriaca (Culot, 1917).


31-7-2023 MONTE CORONA, VALENCIA - ELM LEAF BEETLE (Xanthogaleruca luteola)

Xanthogaleruca luteola, commonly known as the elm-leaf beetle, is a beetle species in the family Chrysomelidae that is native to Europe but invasive in other parts of the world.

The imago (adult beetle) is 6–8 mm in length, and ranges from yellow to green in colour, with a spot on its head, an hourglass mark and two spots on the pronotum, and a broad, dark stripe along the edge of each elytron. The larvae are usually black, occasionally black and yellow, with multiple rows of dots on the back and on the sides and < 13 mm long. The pupae are orange-yellow with black chaetae. The ova are yellow, and laid in spindle-like clusters of < 25 on the undersides of the elm leaves.

These beetles are common in the Western Palearctic realm from Portugal to Central Asia. Indigenous to Europe, they were accidentally introduced to North America and Australia, and are now widespread, and are serious pests in Australia and parts of North America.

The first and most apparent symptoms are of skeletonization. During feeding, elm leaf beetle larvae skeletonize the leaves. They leave the outer edge and veins of the leaf intact, which gives the foliage a net-like appearance. Areas around the feeding site dry up and die, causing the leaf to drop prematurely. Adults, on the other hand, chew small, irregularly shaped holes in the expanding leaves. Trees that lose their leaves often develop a second set, only to have them consumed when the next generation is produced

28-5-2023 TABIN RESERVE, BORNEO - HORSFIELD'S BARON BUTTERFLY (MALE) (Tanaecia iapis) COURTESY OF MRS VALERIE FISHER


The Horsfield's Baron (Tanaecia iapis puseda). This species prefers the sanctuary of the forested areas in Singapore, although they are sometimes found in public parks and gardens. Males are more often seen than females. The male of this species exhibits 'territorial' behaviour, where it perches on a few favourite locations and dives to chase away any intruders into its space - even a stone thrown into its domain of supervision will be similarly chased away!

27-5-2023 TABIN RESERVE, BORNEO - CHANGEABLE HAWK EAGLE (Nisaetus cirrhatus)


The changeable hawk-eagle (Nisaetus cirrhatus) or crested hawk-eagle is a large bird of prey species of the family Accipitridae. More informal or antiquated English common names include the marsh hawk-eagle or Indian crested hawk-eagle. It is a member of the subfamily Aquilinae, with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus. It was formerly placed in the genus Spizaetus, but studies pointed to the group being paraphyletic resulting in the Old World members being placed in Nisaetus and separated from the New World species. It is a typical “hawk-eagle” in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between birds, mammals or reptiles as well as other vertebrates. Among the members of its genus, the changeable hawk-eagle stands out as the most widely distributed, adaptable and abundant species. Individuals show a wide range of variation in plumage from pale to dark, varying with moult and age giving rise to the name "changeable". 

18-5-2023 SEPILOK, BORNEO - SOUTHERN PIG TAILED MACAQUE (Macaca nemestrina) (FEMALE) (COURTESY OF MRS VALERIE FISHER)


The southern pig-tailed macaque (Macaca nemestrina), also known as the Sundaland pig-tailed macaque and Sunda pig-tailed macaque, is a medium-sized macaque that lives in southern Thailand, Malaysia, and Indonesia. It is known locally as berok.

M. nemestrina is mainly terrestrial, but also a skilled climber. Unlike almost all primates, these macaques love water. They live in large groups that split into smaller groups during daytime when they are foraging. They are omnivorous, feeding mainly on fruits, seeds, berries, cereals, fungi, and invertebrates. A study in peninsular Malaysia found them to be the primary, and perhaps the only, seed dispersers of the rattan species Daemonorops calicarpa and Calamus castaneus.

There is a hierarchy among males, based on strength, and among females, based on heredity. Thus, the daughter of the alpha female will immediately be placed above all other females in the group. The alpha female leads the group, while the male role is more to manage conflict within the group and to defend it.

Female gestation lasts around 5.7 months. She will give birth to one infant every two years. Weaning occurs at 4–5 months. Sexual maturity is reached at 3–5 years.

In Thailand, they have been trained for 400 years to harvest coconuts.

This macaque is mostly found in rainforest up to 2,000 metres (6,600 ft), but will also enter plantations and gardens.

It is found in the southern half of the Malay Peninsula (only just extending into southernmost Thailand), Borneo, Sumatra and Bangka Island. There are reports of the species having been present in Singapore before 1950, but these were likely escaped pets. The only pig-tailed macaques in Singapore today are introduced monkeys.
