10-9-2016 MONTE CORONA, VALENCIA - BROAD SCARLET DRAGONFLY (MALE) (Crocothemis erythraea)

The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.

The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China. It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.

A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.

Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.

15-5-2015 EBRO DELTA, TARRAGONA - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)

The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.

The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.

The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist Gerard Troost. Trachemys scripta troostii is now the scientific name for another subspecies, the Cumberland slider.

The carapace of this species can reach more than 40 cm (16 in) in length, but the typical length ranges from 15 to 20 cm (6 to 8 in). The females of the species are usually larger than the males. They typically live between 20-30  years, although some individuals can live for more than 70 years. Their life expectancy is shorter when they are kept in captivity. The quality of their living environment has a strong influence on their lifespans and well being.

The shell is divided into the upper or dorsal carapace, and the lower, ventral carapace or plastron. The upper carapace consists of the vertebral scutes, which form the central, elevated portion; pleural scutes that are located around the vertebral scutes; and then the marginal scutes around the edge of the carapace. The rear marginal scutes are notched. The scutes are bony keratinous elements. The carapace is oval and flattened (especially in the male) and has a weak keel that is more pronounced in the young. The color of the carapace changes depending on the age of the turtle. It usually has a dark green background with light and dark, highly variable markings. In young or recently hatched turtles, it is leaf green and gets slightly darker as a turtle gets older, until it is a very dark green, and then turns a shade between brown and olive green. The plastron is always a light yellow with dark, paired, irregular markings in the centre of most scutes. The plastron is highly variable in pattern. The head, legs, and tail are green with fine, irregular, yellow lines. The whole shell is covered in these stripes and markings that aid in camouflaging an individual.

These turtles also have a complete skeletal system, with partially webbed feet that help them to swim and that can be withdrawn inside the carapace along with the head and tail. The red stripe on each side of the head distinguishes the red-eared slider from all other North American species and gives this species its name, as the stripe is located behind the eyes, where their (external) ears would be. These stripes may lose their color over time. Color and vibrance of ear stripe can indicate immune health, with bright red having higher immune response than yellow stripes. Some individuals can also have a small mark of the same color on the top of their heads. The red-eared slider does not have a visible outer ear or an external auditory canal; instead, it relies on a middle ear entirely covered by a cartilaginous tympanic disc.

Like other turtles, the species is poikilotherm and thus dependent on the temperature of its environment. For this reason, it needs to sunbathe frequently to warm up and maintain body temperature.

15-5-2015 EBRO DELTA, TARRAGONA - PAINTED LADY BUTTERFLY (Vanessa cardui)

Painted Lady butterflies are best known for their impressive migrations, which unlike many other migratory species, do not follow a seasonal pattern. Some hypothesize that their migratory patterns are influenced by heavy rains like El Niño, which may impact the abundance of their larval hostplants.

The Painted Lady butterflies are one of the brush-footed butterflies (family Nymphalidae), also called four-footed butterflies. They have a five to nine-centimeter wingspan and live for about two to four weeks.

Archive. This butterfly is known by three names; Cosmopolitan for its global span, Thistle for its favored food, and Painted Lady for its impressive display. Painted lady butterflies migrate like monarchs. Unlike them, they don't seem to follow seasonal or geographic patterns.

The Painted Lady butterflies are one of the brush-footed butterflies (family Nymphalidae), also called four-footed butterflies. They have a five to nine-centimeter wingspan and live for about two to four weeks.

15-5-2015 EBRO DELTA, TARRAGONA - BARN SWALLOW (Hirundo rustica)

The sight of an early spring Swallow with its long, forked tail, red throat and white belly signals that summer is not far away.

A long-distance migrant, many of our Swallows spend the winter months in South Africa. The first Swallows begin to arrive in the UK during March and stay here into October. In recent years a small number of birds have attempted, in some years successfully, to overwinter in the UK.

The Swallow can be found across Britain & Ireland and can be seen flying at speed just inches above its favoured grassland feeding habitat as it snatches its insect prey. UK Swallow have fluctuated sharply in recent decades, with declines seen in England, Wales, Scotland and Northern Ireland since about 2010.

15-5-2015 EBRO DELTA, TARRAGONA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

Cormorants were once entirely coastal in habits but we have seen an increasing trend for inland breeding, a behaviour first documented here in the 1950s.

Our population is made up of birds from two different races, one of which – the continental race – is responsible for the colonisation of inland waterbodies. Cormorants make use of regular roosting sites, with some individuals remarkably faithful to these over time.

The expansion inland has brought the Cormorant into conflict with commercial fisheries and anglers, and the presence of these birds has not been welcomed by all.

15-5-2015 EBRO DELTA, TARRAGONA - EURASIAN REED WARBLER (Acrocephalus scirpaceus)

The common reed warbler (Acrocephalus scirpaceus) is an Old World warbler in the genus Acrocephalus. It breeds across Europe into the temperate western Palaearctic where it is migratory, wintering in sub-Saharan Africa. It is also a resident species over large parts of Africa.

This is a medium-sized warbler, 13 cm (5.1 in) in length with a wing-span of 17–21 cm (6.7–8.3 in). The adult has an unstreaked brown back and buff underparts. The forehead is flattened, and the bill is strong and pointed. The sexes are identical, as with most warblers, but young birds are richer buff below. The common reed warbler looks similar to the great reed warbler, but the great reed warbler is larger in size and has a stronger supercilium.

The song is a slow, chattering jit-jit-jit with typically acrocephaline whistles and mimicry added.

This small passerine bird is a species found almost exclusively in reed beds, usually with some bushes.

Like most warblers, it is insectivorous, but will occasionally take plant material such as berries.

The males return to the breeding grounds two or three weeks before the females. The species is usually monogamous. The first eggs are laid at the end of April. The nest is usually placed in vegetation over water, especially in reeds of the genus Phragmites. The deep cylindrical cup nest is sited on average 65 cm (26 in)—range is between 20 and 140 cm (7.9 and 55.1 in)—above the surface of the water and is built entirely by the female. She takes four days to build the initial cup of grass, reed stems and leaves, and another three days to complete the lining of finer material including hair. The clutch contains three to five eggs that are laid daily. The eggs are very pale green with speckles and blotches of olive green or grey. On average they measure 18.4 mm × 13.6 mm (0.72 in × 0.54 in) and weigh 1.75 g (0.06 oz). They are incubated by both parents, beginning after the penultimate egg is laid. Only the female incubates at night. The eggs hatch after 9–12 days. The nestlings are fed and cared for by both parents. They fledge after 10–12 days but continue to be fed by their parents for another 10–14 days. Up to one third of pairs raise a second brood.

The common reed warbler is one of the species that are brood parasitised by the common cuckoo.

15-5-2015 EBRO DELTA, TARRAGONA - EURASIAN HOOPOE (Upupa epops)

Unmistakable, with its down-curved bill, black, white and sandy brown plumage – not to mention its crest – this is a striking visitor to our shores, most often encountered in spring but with records from all months.

With a wide breeding range, extending from Portugal in the west to China in the east, the Hoopoe breeds as far north as Estonia.

Occasional pairs have bred here in Britain, although we lack the abundance of grasshoppers, crickets and small lizards that are the favoured prey within its core breeding range.

11-5-2015 ADSUBIA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

P. megera L. [— xiphie Boisd. pt (45d). Above reddish yellow, with a black mark which traverses the distal band from the cell of the forewing to the abdominal margin of the hindwing, short black stripes crossing the disc and the cell of the forewing.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

30-4-2015 GANDIA, VALENCIA - EURASIAN BLACKBIRD (FEMALE) (Turdus merula)

The common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. It breeds in Europe, Asiatic Russia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered to be full species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory.

The adult male of the common blackbird (Turdus merula merula, the nominate subspecies), which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a rich, melodious song; the adult female and juvenile have mainly dark brown plumage. This species breeds in woods and gardens, building a neat, cup-shaped nest, bound together with mud. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.

Both sexes are territorial on the breeding grounds, with distinctive threat displays, but are more gregarious during migration and in wintering areas. Pairs stay in their territory throughout the year where the climate is sufficiently temperate. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

29-4-2015 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).

20-4-2015 NICOSIA, CYPRUS - HOODED CROW (Corvus cornix)

The hooded crow (Corvus cornix), also called the scald-crow or hoodie, is a Eurasian bird species in the genus Corvus. Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.

The hooded crow is so similar in morphology and habits to the carrion crow (Corvus corone) that for many years they were considered by most authorities to be geographical races of one species. Hybridization observed where their ranges overlapped added weight to this view. However, since 2002, the hooded crow has been elevated to full species status after closer observation; the hybridisation was less than expected and hybrids had decreased vigour. Within the hooded crow species, four subspecies are recognized, with one, the Mesopotamian crow, possibly distinct enough to warrant species status itself. 

19-4-2015 JERUSALEM, ISRAEL - HOUSE SPARROW (MALE) (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.

19-4-2015 JERUSALEM, ISRAEL - EGYPTIAN ROCK AGAMA (Laudakia vulgaris)

Laudakia vulgaris, also known as Egyptian rock agama, is a species of agamid lizard. It is found in Egypt, Jordan, Israel, Syria, southern Lebanon, and northern Saudi Arabia.

Rock agamas are diurnal creatures and remain active throughout the day except for the hottest hour when even shady spots can reach 38°C (100°F). Days are spent hunting for food and basking in the sun. Males are territorial and must fight other males to claim their space. Agamas live in social groups including a lead male, about half a dozen females, and subordinate males. Subordinate males can only gain their own group if they eliminate the existing lead male (the "cock") or establish a colony outside all other cocks' territory. The center of a cock's territory is usually marked by the presence of a physical object, such as a tree or boulder, on which the lizards congregate. In urban areas, fights between males are more common because space is at a higher premium.

7-9-2016 MONTE CORONA, VALENCIA - LONG TAILED TIT (Aegithalos caudatus)

The long-tailed tit (Aegithalos caudatus), also named long-tailed bushtit, is a common bird found throughout Europe and the Palearctic. The genus name Aegithalos was a term used by Aristotle for some European tits, including the long-tailed tit.

The long-tailed tit is globally widespread throughout temperate Northern Europe and the Palearctic, into boreal Scandinavia and south into the Mediterranean zone. It inhabits deciduous and mixed woodland with a well-developed shrub layer, favouring edge habitats. It can also be found in scrub, heathland with scattered trees, bushes and hedges, in farmland and riverine woodland, parks and gardens. The bird's year-round diet of insects and social foraging bias habitat choice in winter towards deciduous woodland, typically of oak, ash and locally sycamore species. For nesting, strong preference is shown towards scrub areas. The nest is often built in thorny bushes less than 3 metres (10 feet) above the ground.

The long-tailed tit is insectivorous throughout the year. It eats predominantly arthropods, preferring the eggs and larvae of moths and butterflies. Occasional vegetable matter (such as seeds) is taken in the autumn.

The nest of the long-tailed tit is constructed from four materials: lichen, feathers, spider egg cocoons and moss, with over 6,000 pieces used for a typical nest. The nest is a flexible sac with a small, round entrance at the top, suspended either low in a gorse or bramble bush or high up in the forks of tree branches. The structural stability of the nest is provided by a mesh of moss and spider silk; the tiny leaves of the moss act as hooks and the spider's silken thread provides the loops, thus producing a natural form of velcro. The tit lines the outside with hundreds of flakes of pale lichens to provide camouflage. The inside of the nest is lined with more than 2,000 downy feathers to provide insulation. The nests suffer a high rate of predation, with only 17% success.

18-4-2015 HAIFA, ISRAEL - HOODED CROW (Corvus cornix)

The Hooded crow (Corvus cornix) is a Eurasian bird species in the genus Corvus. Like other corvids, it is an omnivorous and opportunistic forager and feeder. The Hooded crow is so similar in morphology and habits to the Carrion crow that for many years they were considered by most authorities to be geographical races of one species.

Except for the head, throat, wings, tail, and thigh feathers, which are black and mostly glossy, the plumage of the Hooded crow is ash-grey, with the dark shafts giving it a streaky appearance. The bill and legs are black; the iris dark brown. Only one moult occurs, in autumn, as in other crow species. Male Hooded crows tend to be larger than females, although the two sexes are otherwise similar in appearance. Their flight is slow, heavy and usually straight. When first hatched, the young are much blacker than the parents. Juveniles have duller plumage with bluish or greyish eyes, and initially possess a red mouth.

Hooded crows are found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East and Northeast Africa. Some birds are migratory and may move further south in winter. Hooded crows live in various habitats such as woodland edges, coastal cliffs, inshore islands, estuaries, moorland, cultivated areas, city parks, and gardens.

Hooded crows are social birds; they live in pairs ad may also feed in groups. They are active during the day spending most of the time searching for food. Hooded crows are known for their habit of hiding food, especially meat or nuts, in places such as rain gutters, flower pots, or in the earth under bushes, to feed on it later. Other crows often watch if another one hides food and then search this place later when the other crow has left.

Hooded crows are omnivores and scavengers. They feed on insects, berries, grain, mollusks, crabs, and carrion. On coastal cliffs, they often steal the eggs of gulls, cormorants, and other birds. Hooded crows may even enter the burrow of the puffin to steal eggs.

7-4-2015 DUBAI, UAE - WHITE EARED BULBUL (Pycnonotus leucotis)

The white-eared bulbul (Pycnonotus leucotis) is a member of the bulbul family. It is found in south-western Asia from India to the Arabian peninsula.

The white-eared bulbul was originally described in the genus Ixos. The white-eared bulbul is considered to belong to a superspecies along with the Himalayan bulbul, white-spectacled bulbul, African red-eyed bulbul, Cape bulbul, and the common bulbul. Formerly, some authorities considered the white-eared bulbul to be a subspecies of the Himalayan Bulbul.

Two subspecies are recognized:

Arabian white-cheeked bulbul (P. l. mesopotamia) - Ticehurst, 1918: Found in north-eastern Arabia, southern Iraq and south-western Iran

P. l. leucotis - (Gould, 1836): Found in southern Iran, southern Afghanistan, Pakistan and north-western India

The white-eared bulbul is rotund in appearance, and has a brownish-grey body. The tail of this bird is relatively long, tapering outwards. Starting off black, the tail feathers end in white tips. The head of the white-eared bulbul is black, with the area around its cheeks bearing a large white spot. The eye rings of the bulbul are bare, and the beak short. The vent of the bird is bright yellow.

The white-eared bulbul does not have a uniform song but rather a set of notes, which can be used to chirp different melodies. The song is brief, but is described as being "pleasant and fluid."

It is native to the western reaches of India, much of Pakistan, southern Afghanistan, coastal Iran, as well as much of the two-river basin in Iraq, Kuwait, and the island of Bahrain.

It has been introduced to the remaining Persian Gulf countries including Oman, the UAE, and Qatar. 

1-4-2015 ELEPHANTA ISLAND, MUMBAI - COMMON MYNA (Acridotheres tristis)

The Common myna (Acridotheres tristis) is a tropical bird with a strong territorial instinct, which has adapted extremely well to urban environments. The range of the Common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture, and human interests.

Common mynas can be recognized by their brown body, black hooded head, and the bare yellow patch behind the eye. Their bill and legs are bright yellow. There is a white patch on the outer primaries and the wing lining on the underside is white. The male and female look similar and are usually seen in pairs.

29-3-2015 COCHIN, INDIA - HOUSE CROW (Corvus splendens)

The house crow (Corvus splendens), also known as the Indian, greynecked, Ceylon or Colombo crow, is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping. It is between the jackdaw and the carrion crow in size (40 cm (16 in) in length) but is slimmer than either. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in colour. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of colour in areas of the plumage.

It has a widespread distribution in southern Asia, being native to Nepal, Bangladesh, India, Pakistan, Sri Lanka, Maldives and Laccadive Islands, southern Myanmar, south Thailand, and coastal southern Iran. It was introduced to East Africa around Zanzibar (about 1897) and Port Sudan. It arrived in Australia via ship but has up to now been exterminated. Recently, it has made its arrival in Europe and has been breeding in the Dutch harbour town Hook of Holland since 1998.

A population between 200 and 400 birds has been present in Sham Shui Po, New Kowloon, Hong Kong, in particular Lai Kok Estate and Sham Shui Po Park, as well as Kowloon Tsai Park in Kowloon Tsai. An individual has been present in Cork Harbour on the south coast of Ireland since early September 2010.

In the New World, a small population of house crows is established in the area around St. Petersburg, Florida. As of April 2009, the introduced population of house crows in Socotra Island, Yemen, has been eradicated to avoid negative ecological effects to endemic species of Socotra.

It is associated with human settlements throughout its range, from small villages to large cities. In Singapore, there was a density of 190 birds/km2 in 2001 with efforts to suppress the population in planning.

Due to a human population explosion in the areas it inhabits, this species has also proportionately multiplied. Being an omnivorous scavenger has enabled it to thrive in such circumstances.

27-3-2015 COLOMBO, SRI LANKA - SPOT BILLED PELICAN (Pelecanus philippensis)

The spot-billed pelican (Pelecanus philippensis ) or grey pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.

This species was once used by fishermen in parts of eastern Bengal as decoys for certain fish. These fishermen believed that an oily secretion from the bird attracted certain fish such as Colisa and Anabas.

The propensity of these birds to nest close to human habitations has been noted from the time of T C Jerdon:

Several colonies have since been discovered and while many of these have vanished others have been protected and a few villages with nesting colonies have become popular tourist attractions. Well known villages with colonies include Kokrebellur, Koothankulam and Uppalapadu.

The spot-billed pelican is a. It is 125–152 cm (49–60 in) long and a weight of 4.1–6 kg (9.0–13.2 lb). It is mainly white, with a grey crest, hindneck and a brownish tail. The feathers on the hind neck are curly and form a greyish nape crest. The pouch is pink to purplish and has large pale spots, and is also spotted on the sides of the upper mandible. The tip of the bill (or nail) is yellow to orange. In breeding plumage, the skin at the base of the beak is dark and the orbital patch is pink. In flight they look not unlike the Dalmatian pelican but the tertials and inner secondaries are darker and a pale band runs along the greater coverts. The tail is rounder.

The newly hatched young are covered in white down. They then moult into a greyish speckled plumage. The spots on the bill appear only after a year. The full adult breeding plumage appears in their third year.

The species is found to breed only in peninsular India, Sri Lanka and in Cambodia. A few birds from India are known to winter in the Gangetic plains but reports of its presence in many other parts of the region such as the Maldives, Pakistan and Bangladesh has been questioned. The main habitat is in shallow lowland freshwaters. The spot-billed pelican is not migratory but are known to make local movements and are more widely distributed in the non-breeding season.

This species is a colonial breeder, often breeding in the company of other waterbirds. The nests are on low trees near wetlands and sometimes near human habitations. Many large breeding colonies have been recorded and several have disappeared over time. In June 1906, C E Rhenius visited a colony in Kundakulam in Tirunelveli district where the villages considered the birds semi-sacred. The same colony was revisited in 1944, and was found to have about 10 nests of pelicans and nearly 200 nests of painted stork.

27-3-2015 GALLE, SRI LANKA - YELLOW BILLED BABBLER (Turdoides affinis)

The yellow-billed babbler is a common resident breeding bird in Sri Lanka and southern India. Its habitat is scrub, cultivation and garden land. This species, like most babblers, is not migratory, and has short rounded wings and a weak flight and is usually seen calling and foraging in groups. It is often mistaken for the jungle babbler, whose range overlaps in parts of southern India, although it has a distinctive call and tends to be found in more vegetated habitats. Its name is also confused with Turdoides leucocephala, which is also known as white-headed babbler.

The yellow-billed babbler was formerly placed in the genus Turdoides but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Argya.

The yellow-billed babbler (Argya affinis) is a member of the family Leiothrichidae endemic to southern India and Sri Lanka. These birds have grey brown upperparts, a grey throat and breast with some mottling, and a pale buff belly. The head and nape are grey, and the eyes are bluish white. The nominate race, found in southern India, has a whitish crown and nape, with a darker mantle. The rump is pale and the tail has a broad dark tip. The Sri Lankan subspecies A. a. taprobanus is drab pale grey. Birds in the extreme south of India are very similar to the Sri Lankan subspecies with the colour of the crown and back being more grey than the nominate race. The Indian form is more heavily streaked on the throat and breast. The Sri Lankan subspecies resembles the jungle babbler, Turdoides striatus, although that species does not occur on the island.

Seven distinctive vocalisations have been noted in this species and this species has a higher pitched call than the jungle babbler. The jungle babbler has calls that have a harsher and nasal quality.

The taxonomy of this species was confused in the past and confounded with the sympatric jungle babbler and the orange-billed babbler of Sri Lanka.

This species is patchily distributed in southern India and Sri Lanka. The nominate subspecies is found in Andhra Pradesh, south of the Godavari river and Karnataka south of Belgaum into Tamil Nadu. It prefers lower altitudes and drier habitats than the jungle babbler but sometimes is found alongside it. The Sri Lankan subspecies is found in the lowlands and hills up to about 1500m avoiding heavy forest. It is a common garden bird and frequently visits urban and suburban areas.

The yellow-billed babbler lives in flocks of seven to ten or more. It is a very noisy bird, and the presence of a flock may generally be known at some distance by the continual chattering, squeaking and chirping produced by its members. Sometimes, all the members start chattering loud enough to irritate the human ear significantly. One member often perches high and acts as a sentinel while the remaining members of the flock forage on or close to the ground. They feed mainly on insects, but also eat fruit, nectar and human food scraps. They have been known to take Calotes versicolor lizards and whip-scorpions. They do not fly long distances; the maximum distance flown non-stop was about 180 m and prior to flying, they usually gain height by moving up a tree or tall shrub. Black drongos, rufous treepies and Indian palm squirrels are often seen foraging near these babblers.

Yellow-billed babblers allopreening

The babblers wake before dawn around 6:00 AM and begin foraging. They are relatively inactive in the hot hours of the day from 1:30 PM to 4:30 PM. They assemble in groups around 7:00 PM and preen themselves before going to roost. Members of a group roost next to each other with some juveniles wedging themselves in the middle of the group. When foraging the sentinel bird calls with wing fluttering and hopping. Allopreening is a common activity, particularly in winter, and members may beg for food from other members. Yellow-billed babblers particularly like to bathe, and may visit birdbaths in their general territories, usually around late afternoon to evening. Sometimes these birds have been observed visiting bird baths at around 6:30 PM, after sunset.

A study in the Sivakasi plains noted that groups had a home range of 0.4 km2 and the population density was about 55 birds per km2.

Nests of the species are seen throughout the year but the peak breeding season is prior to the onset of the Indian southwest monsoon. Nests are built in trees, concealed in dense masses of foliage. The majority of nests are built below a height of four metres from the ground. The nest is a small cup placed in a fork of a branch. The normal clutch is two to four turquoise blue eggs, although up to five may be laid by birds in the hills of Sri Lanka. The eggs hatch after 14 to 16 days. The brooding parent bird often stands on the rim of the nest rather than sit on the chicks. Brood parasitism of the babblers' nests by the pied cuckoo (Clamator jacobinus) is known from both India and Sri Lanka. The common hawk-cuckoo has also been noted as a brood parasite. In an exceptional case, jungle babblers have been seen feeding the chicks of the yellow-billed babbler. Chicks are mainly fed insects and the occasional lizard. Like most perching birds, the parents take care of nest sanitation, removing the faecal sacs of the young, typically by swallowing them. Helpers have been seen to assist the parents in building the nest as well as in feeding the chicks at the nest.
