31-3-2025 GOATFELL LODGE, SRI LANKA - COMMON MYNA (Acridotheres tristis)

The common myna or Indian myna (Acridotheres tristis), sometimes spelled mynah, is a bird in the family Sturnidae, native to Asia. An omnivorous open woodland bird with a strong territorial instinct, the common myna 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. In particular, the species poses a serious threat to the ecosystems of Australia, where it was named "The Most Important Pest/Problem" in 2008.

The common myna is readily identified by the brown body, black hooded head and the bare yellow patch behind the eye. The bill and legs are bright yellow. They have rounded wings as well, and a round square tipped tail. There is a white patch on the outer primaries and the wing lining on the underside is white, as well as having a white tail tip. The sexes are similar and birds are usually seen in pairs. The common myna obeys Gloger's rule in that the birds from northwestern India tend to be paler than their darker counterparts in southern India.

The calls includes croaks, squawks, chirps, clicks, whistles and 'growls', and the bird often fluffs its feathers and bobs its head in singing. The common myna screeches warnings to its mate or other birds in cases of predators in proximity or when it is about to take off flying. Common mynas are popular as cage birds for their singing and "speaking" abilities. Before sleeping in communal roosts, common mynas vocalise in unison, which is known as "communal noise".

The common myna is native to Asia, with its initial home range spanning Iran, Pakistan, India, Nepal, Bhutan, Bangladesh and Sri Lanka, Afghanistan, Uzbekistan, Tajikistan, Turkmenistan, Myanmar, Malaysia, Singapore, peninsular Thailand, Indochina, Japan (both mainland Japan and the Ryukyu Islands) and China.

The common myna has been introduced to many other parts of the world such as Canada, Australia, Israel, New Zealand, New Caledonia, Fiji, the United States (South Florida only), South Africa, Kazakhstan, Kyrgyzstan Uzbekistan, the Cayman Islands, islands in the Indian Ocean (the Seychelles – from which it was subsequently eradicated at great expense, Mauritius, Réunion, Madagascar, the Maldives, the Andaman and Nicobar Islands and the Lakshadweep archipelago) and also in islands of the Atlantic (such as Ascension and Saint Helena, Pacific Ocean and Cyprus February 2022. The range of the common myna is increasing to the extent that in 2000 the IUCN Species Survival Commission declared it among 100 of the world's worst invasive species.

It is typically found in open woodland, cultivation and around habitation. Although it is an adaptable species, its population is abnormal and very much considered a pest in Singapore (where it is locally called as gembala kerbau, literally 'buffalo shepherd') due to competition with the related introduced Javan myna.

The common myna thrives in urban and suburban environments; in Canberra, for instance, 110 common mynas were released between 1968 and 1971. By 1991, common myna population density in Canberra averaged 15 birds per square kilometer. Only three years later, a second study found an average population density of 75 birds per square kilometer in the same area.

31-3-2025 GOATFELL LODGE, SRI LANKA - INDIAN BLACKBIRD (Turdus simillimus)

The Indian blackbird (Turdus simillimus) is a member of the thrush family Turdidae. It was formerly considered a subspecies of the common blackbird. It is found only in India and Sri Lanka. The subspecies from most of the Indian subcontinent, simillimus, nigropileus, bourdilloni and spencei, are small, only 19–20 centimetres (7.5–7.9 inches) long, and have broad eye-rings. They also differ in proportions, wing formula, egg colour and voice from the common blackbird. 

Dark thrush with a bright orange bill. Male is slightly darker than the female. Plumage varies slightly throughout range, Sri Lanka birds being midnight-black and central Indian “Black-capped” birds being brown with a black head and wings. Note the small teardrop-shaped patch of bare orange skin around the eye. Beautiful fluting song often heard from foothill forests, forest edge, and orchards; winters at lower altitudes, often in closer proximity to people, though typically not in outright urban areas like Chinese and Eurasian Blackbirds.

31-3-2025 GOATFELL LODGE, SRI LANKA - CINCEROUS TIT (Parus cinereus)

The cinereous tit (Parus cinereus) is a species of bird in the tit family Paridae. This species is made up of several populations that were earlier treated as subspecies of the great tit (Parus major). These birds are grey backed with white undersides. The great tit in the new sense is distinguishable by the greenish-back and yellowish underside. The distribution of this species extends from parts of West Asia across South Asia and into Southeast Asia.

The Japanese tit was formerly treated as a separate species but is now lumped together with the cinereous tit. These birds are usually seen in pairs or small groups that sometimes join mixed-species foraging flocks. They forage mainly by gleaning, capturing insects (mainly caterpillars, bugs and beetles) that are disturbed and will also feeding on buds and fruits They sometimes use their feet to hold insects which are then torn with their beak. They may also wedge hard seeds in a bark crevice before hammering them with their beak (noted in ssp. caschmirensis). Like others in the genus, it has a broad black ventral line and has no crest. 

This tit is part of a confusing group of species but is distinct in having a grey-back, black hood, white cheek patch and a white wing-bar. The underparts are white with the black central stripe running along the length. The female has a narrower ventral line and is slightly duller. The upper tail coverts are ashy while the tail is black with the central 4 pairs of feathers ashy on the outer webs and all but the central pair are tipped white. The fifth pair is white with a black rachis and a band of black on the inner web. The outermost pair of tail feathers are all white with a black shaft. The undertail coverts are black towards the centre but white on the sides.

30-3-2025 LEOPARD TRAILS LODGE, SRI LANKA - PALE BILLED FLOWERPECKER (Dicaeum erythrorhynchos)

The pale-billed flowerpecker or Tickell's flowerpecker (Dicaeum erythrorhynchos) is a tiny bird that feeds on nectar and berries, found in India, Sri Lanka, Bangladesh and western Myanmar. The bird is common especially in urban gardens with berry bearing trees. They have a rapid chipping call and the pinkish curved beak separates it from other species in the region.

This is a tiny bird, 8 cm long, and is one of the smallest birds occurring in most parts of southern India and Sri Lanka. The bird is plain brownish to olive green. The underside is buff olive and does not contrast greatly with the upperparts and not whitish as in the Nilgiri flowerpecker of the Western Ghats and Nilgiri hills nor is it streaked as in the thick-billed flowerpecker. The Nilgiri flowerpecker has a pale supercilium unlike this species which has no marking on the head. The Sri Lankan race ceylonense Babault, 1920 - is greyer and smaller than the nominate race of peninsular India. It has been considered one of the early flowerpeckers, originating in the Malay Peninsula, to colonize the Indian Subcontinent.

30-3-2025 GOATFELL NUMARA ELIYA, 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

29-3-2025 YALA NAT PARK, SRI LANKA - COMMON WATER HYACINTH (Pontederia crassipes)

Pontederia crassipes (formerly Eichhornia crassipes), commonly known as common water hyacinth, is an aquatic plant native to South America, naturalized throughout the world, and often invasive outside its native range. It is the sole species of the subgenus Oshunae within the genus Pontederia. Anecdotally, it is known as the "terror of Bengal" due to its invasive growth tendencies.

29-3-2025 YALA NAT PARK, SRI LANKA - GREY HERON (Ardea cinerea)

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

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

29-3-2025 LEOPARD TRAILS LODGE, SRILANKA - LITTLE CORMORANT (Microcarbo niger)

The little cormorant (Microcarbo niger ) is a member of the cormorant family of seabirds. Slightly smaller than the Indian cormorant it lacks a peaked head and has a shorter beak. It is widely distributed across the Indian Subcontinent and extends east to Java, where it is sometimes called the Javanese cormorant. It forages singly or sometimes in loose groups in lowland freshwater bodies, including small ponds, large lakes, streams and sometimes coastal estuaries. Like other cormorants, it is often found perched on a waterside rock with its wings spread out after coming out of the water. The entire body is black in the breeding season but the plumage is brownish, and the throat has a small whitish patch in the non-breeding season. These birds breed gregariously in trees, often joining other waterbirds at heronries.

Little cormorants are vocal near their nest and roosts where they produce low roaring sounds. They also produce grunts and groans, a low pitched ah-ah-ah and kok-kok-kok calls. They roost communally often in the company of other waterbirds.

Little cormorants tend to forage mainly in small loose groups and are often seen foraging alone. They swim underwater to capture their prey, mainly fish. A study in northern India found that the little cormorant fished in water which was less than a metre deep and captured fishes of about 2–8 centimetres (0.79–3.15 in) length. They propel themselves underwater using their webbed feet. Captured fishes are often brought up to the surface to swallow them and during this time other birds including other little cormorants, painted storks, gulls and egrets may attempt to steal them. Indian cormorants tend to fish communally in larger groups. Like all other cormorants, they will emerge from water and will hold out their wings and stay immobile for a while. The behaviour has been suggested to be for wing-drying, but this interpretation is debated. A study in Sri Lanka found that the time spent with spread wings was always after they had spent some time underwater, and that the duration was related to time spent underwater and inversely related to the temperature and dryness of air. These observations support the theory that the studied behaviour aids drying of the wings.

The breeding season of the little cormorant is between July to September in Pakistan and northern India and November to February in southern India. In Sri Lanka it is December to May. A study in Bangladesh found them to breed from May to October. Males display at the nest site by fluttering their wings while holding their head back and bill raised. They then lower the bill, and after pairing the male also provides food to the female in courtship feeding. Both parents take part in building the nest, which is a platform of sticks placed on trees and sometimes even on coconut palms. They may nest beside Indian pond herons and little egrets in colonies. The nest is built in about two weeks. The whitish eggs turn muddy with age and incubation begins when the first egg is laid. This leads to asynchronous hatching and the chicks in a nest can vary considerably in age. The clutch size can vary from two to six eggs laid at intervals of about two days. The eggs hatch after 15 to 21 days. The downy chicks have a bare red head. The young birds are able to leave the nest after about a month.

28-3-2025 BUNDALA NAT PARK, SRI LANKA - RUDDY TURNSTONE (Arenaria interpres)

The ruddy turnstone (Arenaria interpres ) is a small wading bird, one of two species of turnstone in the genus Arenaria.

It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and is often known simply as turnstone.

Ruddy turnstones are small highly migratory wading birds. In all seasons, their plumage is dominated by a harlequin-like pattern of black and white. Breeding birds have reddish-brown upperparts with black markings. The head is mainly white with black streaks on the crown and a black pattern on the face. The breast is mainly black apart from a white patch on the sides. The rest of the underparts are white. The females are slightly duller than the males and have a browner head with more streaking. Non-breeding adults are duller than breeding birds and have dark grey-brown upperparts with black mottling and a dark head with little white. Juvenile birds have a pale brown head and pale fringes to the upperpart feathers creating a scaly impression.

The ruddy turnstone breeds in northern latitudes, usually no more than a few kilometres from the sea. The subspecies A. i. morinella occurs in northern Alaska and in Arctic Canada as far east as Baffin Island. A. i. interpres breeds in western Alaska, Ellesmere Island, Greenland, Norway, Denmark, Sweden, Finland, Estonia and northern Russia. It formerly bred on the Baltic coast of Germany and has possibly bred in Scotland and the Faroe Islands.

In the Americas, the species winters on coastlines from Washington and Massachusetts southwards to the southern tip of South America although it is scarce in southern parts of Chile and Argentina and is only an unconfirmed vagrant in the Falkland Islands. In Europe, it winters in western regions from Iceland, Norway and Denmark southwards. Only small numbers are found on Mediterranean coasts. In Africa, it is common all the way down to South Africa with good numbers on many offshore islands. In Asia, it is widespread in the south with birds wintering as far north as southern China and Japan (mainly in the Ryukyu Islands). It occurs south to Tasmania and New Zealand and is present on many Pacific islands. Some non-breeding birds remain year round in many parts of the wintering range, with some of those birds still taking on breeding plumage in the spring and summer.

The ruddy turnstone has a varied diet including carrion, eggs, fish and plant material but it feeds mainly on invertebrates. Insects and their larvae are particularly important in the breeding season. At other times it also takes crustaceans, spiders, molluscs, and worms. It often flips over stones and other objects to get at prey items hiding underneath; this behaviour is the origin of the name "turnstone". It usually forages in flocks.

They have also been observed preying on the eggs of other bird species such as gulls, terns, ducks, and even other turnstones, though this behaviour is uncommon. In the majority of observed cases, turnstones typically go after undefended or unattended nests, puncturing the shells with their beaks to get at the contents within.

Ruddy turnstones engage in a variety of behaviours to locate and capture prey. These behaviours can be placed into six general categories:-

Routing: The turnstone manipulates piles of seaweed through flicking, bulldozing, and pecking to expose small crustaceans or gastropod molluscs hidden underneath.

Turning stones: As suggested by its name, the turnstone flicks stones with its bill to uncover hidden littorinids and gammarid amphipods.

Digging: With small flicks of its bill, the turnstone creates holes in the ground substrate (usually sand or mud) and then pecks at the exposed prey – often sandhoppers or seaweed flies.

Probing: The turnstone inserts its bill more than a quarter-length into the ground to get at littorinids and other gastropods.

Hammer–probing: The turnstone cracks open its prey's shell by using its bill as a hammer, and then extracts the animal inside through pecking and probing.

Surface pecking: The turnstone uses short, shallow pecks (less than a quarter bill-length) to get at prey at or just below the ground's surface.

There is evidence that turnstones vary between these feeding behaviours based on individual preference, sex, and even social status with respect to other turnstones. In one studied population, dominant individuals tended to engage in routing while preventing subordinates from doing the same. When these dominant individuals were temporarily removed, some of the subordinates started to rout, while others enacted no change in foraging strategy.

28-3-2025 BUNDALA NAT PARK, SRI LANKA - GREAT CRESTED TERN (Thalasseus bergii)

The greater crested tern (Thalasseus bergii), also called crested tern, swift tern, or great crested tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its four or five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to other species in its genus, but can be distinguished by its darker, battleship-grey upperparts, white forehead even in full breeding plumage, and greenish-tinged yellow (not orange or black) bill colour.

The greater crested tern has dark grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter. Its young have a distinctive appearance, with strongly patterned grey, brown and white plumage, and rely on their parents for food for several months after they have fledged. Like all members of the genus Thalasseus, the greater crested tern feeds by plunge diving for fish, usually in marine environments; the male offers fish to the female as part of the courtship ritual.

This is an adaptable species that has learned to follow fishing boats for jettisoned bycatch, and to use unusual nest sites such as the roofs of buildings and artificial islands in salt pans and sewage works. Its eggs and young are taken by gulls and ibises, and human activities such as fishing, shooting and egg harvesting have caused local population declines. There are no global conservation concerns for this bird, which has a stable total population of more than 500,000 individuals.

28-3-2025 BUNDALA NAT PARK, SRI LANKA - 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".

In winter, the forehead becomes white and the body plumage a much paler grey. Juvenile whiskered terns have a ginger scaly back, and otherwise look much like winter adults. The first winter plumage is intermediate between juvenile and adult winter, with patchy ginger on the back.

The whiskered tern eats small fish, amphibians, insects and crustaceans.

The size, black cap, strong bill (29–34 mm in males, 25–27 mm and stubbier in females, with a pronounced gonys) and more positive flight recall common or Arctic tern, but the short, forked-looking tail and dark grey breeding plumage above and below are typically marsh tern characteristics. The summer adult has white cheeks and red legs and bill. The crown is flecked with white in the juvenile, and the hindcrown is more uniformly blackish, though in the winter adult this too is flecked with white. The black ear-coverts are joined to the black of the hindcrown, and the space above is mottled with white, causing the black to appear as a C-shaped band. The sides of the neck are white; this sometimes continues across the nape. The collar is less sharply defined. All through the year the rump is pale grey. In the juvenile, the mantle has a variegated pattern. The feathers of the back and scapulars are dark brown, with prominent broad buff edgings and often subterminal buff bars or centers. There is usually an admixture of new gray feathers, especially on the mantle, quite early in the fall. The mantle is silvery-gray in the adult. The call is a characteristic krekk.

28-3-2025 BUNDALA NAT PARK, SRI LANKA - TIBETAN SAND PLOVER (Anarhynchus atrifrons)

The Tibetan sand plover (Anarhynchus atrifrons) is a small wader in the plover family of birds, breeds in Pamir Mountains, Tian Shan, Tibetan Plateau and south Mongolia, winters in east and south Africa, south, east and southeast Asia.

It was previously considered conspecific with the Siberian (lesser) sand plover, and includes three subspecies: A. a. atrifrons, breeds in Tibet, A. a. pamirensis breeds in Pamir Mountains, and A. a. schaeferi, breeds in Qinghai. 

A study published in 2022 proposed that the "mongolus" group of lesser sand plover is the sister group of greater sand plover, and "atrifrons" group is the sister group of them also. So a taxonomic split of lesser sand plover was needed. The authors suggested new scientific and common English name for them:

Siberian sand plover (Anarhynchus mongolus), A. m. mongolus and A. m. stegmanni;

Tibetan sand plover (Anarhynchus atrifrons), A. a. atrifrons, A. a. pamirensis and A. a. schaeferi;

Desert sand plover (Anarhynchus leschenaultii), currently greater sand plover.

The International Ornithologists' Union accepted the split and renaming of the lesser sand plover in 2023, erecting the Tibetan sand plover as a full species.

Tibetan Sand Plover is a very rare vagrant to the UK.

Formerly a subspecies of ‘Lesser Sand Plover’, this taxon was only recognised as a full species following genetic analysis in 2022. At the time of the review there were six previous UK records of ‘Lesser Sand Plover’, of which just two were of the form now recognised as Tibetan Sand Plover.

Tibetan Sand Plover breeds in mountains and plateaus of Asia and winters widely around the coasts of Asia, the Middle East and south and east Africa.

This species and Siberian Sand Plover were formerly lumped under the name of Lesser Sand Plover (sometimes instead named Mongolian (Sand) Plover).

Subspecies

Clements recognizes these subspecies[1]:

A. a. pamirensis: Pamirs to western China (western Xinjiang); winters to Africa and western India

A. a. atrifrons Himalayas and southern Tibet: winters from India to Sumatra

A. a. schaeferi: Eastern Tibet to southern Mongolia; winters Thailand to Greater Sundas

Breeds at high elevation, above the tree line, usually in dry areas that are near temporary water sources. During migration and winter, their habitat is similar to what would be expected for other plovers.

Strongly migratory; however, birds in their second calendar year may stay in the wintering grounds.

28-3-2025 BUNDALA NAT PARK, SRI LANKA - SRI LANKAN SWALLOW (Cecropis hyperythra)

This bird has been  recently recognized as a distinct species and added to the Sri Lankan endemic list. Sparrow sized and stockier than our other swallows, it is unmistakable with purple-blue glossed upperparts and rusty underparts and rump. Both sexes are alike. Young are duller.

The species is well distributed throughout the island up to about 1500 metres elevation. The birds associate in pairs or more often in scattered groups and spend their time flying after the insect prey they feed on. The usual habitat is open areas such as paddy fields, roadsides, grasslands, grass covered hillsides etc. The flight is typical swallow type with the wings being open and shut at the wrist joint. The birds flutter the wings rapidly and then glide gracefully before fluttering the wings again. The flight is however not as fast as the other swallows’. This species commonly associates with other swallows as well as swifts. They fly high as well as within a few feet from ground level. When not flying the birds sit in an open perch like a bare twig or power cable and preen themselves. The call is a pleasant muffled t’lee easily recognized when once heard. The birds also utter a loud twitter accompanied by a shuffling of wings. 

The Sri Lanka swallow (Cecropis hyperythra) is a resident breeder endemic to Sri Lanka. It is closely related to the red-rumped swallow, and was formerly considered a subspecies.

It is a large swallow with a tail which forks deeply, and the combination of deep rufous underside and navy blue rump without any marks is a unique feature of this species. Its rufous underside can be used to tell it apart from the red-rumped swallow. It is a passerine, which means it has three toes pointing forward and one pointing backward, allowing it to perch.

It is found in a variety of open country habitats in both the lowlands and foothills in Sri Lanka, including farm fields and lightly wooded areas.

27-3-2025 LEOPARD TRAILS LODGE, SRI LANKA - ORIENTAL MAGPIE ROBIN (Copsychus saularis)

The Oriental magpie-robin (Copsychus saularis ) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. These birds are particularly well known for their songs and were once popular as cagebirds.

The Oriental magpie-robin is 19 cm (7.5 in) long, including the long tail, which is usually held cocked upright when hopping on the ground. It is similar in shape to the smaller European robin, but is longer-tailed. The male has black upperparts, head, and throat apart from a white shoulder patch. The underparts and the sides of the long tail are white. Females are greyish black above and greyish white. Young birds have scaly brown upperparts and heads.

Oriental magpie-robins are resident breeders in tropical southern Asia from Nepal, Bangladesh, India, Sri Lanka, and eastern Pakistan, eastern Indonesia, Thailand, south China, Malaysia, and Singapore. They inhabit open woodlands, mangroves, and cultivated areas often close to human habitations.

Oriental magpie-robins breed mainly from March to July in India and January to June in south-east Asia. Males are quite aggressive during this time and defend their territory; they respond to the singing of intruders and even their reflections. Males sing from high perches during courtship. The display of the male involves puffing up the feathers, raising the bill, fanning the tail, and strutting. Oriental magpie-robins nest in tree hollows or niches in walls or buildings, often adopting nest boxes. They line the cavity with grass. The female is involved in most of the nest building, which happens about a week before the eggs are laid. She then lay 4 to 5 eggs at intervals of 24 hours and these are oval and usually pale blue-green with brownish speckles that match the color of hay. The eggs are incubated by the female alone for 8 to 14 days. Both parents take part in raising their chicks which remain in the territory until the next breeding season.

27-3-2025 YALA NAT PARK, SRI LANKA - MUGGER CROCODILE (Crocodylus palustris)

The Mugger crocodile has the broadest snout among living crocodiles. It has a powerful tail and webbed feet. Its visual, hearing, and smelling senses are acute. Hatchlings are pale olive with black spots. Adults are dark olive to grey or brown. The head is rough without any ridges and has large scutes around the neck that are well separated from the back. Scutes usually form 4, rarely 6 longitudinal series and 16 or 17 transverse series. The limbs have keeled scales with serrated fringes on the outer edges, and the outer toes are extensively webbed.

The mugger crocodile occurs in the Indian subcontinent as well as surrounding countries: Sri Lanka in the east, Iran in the west, and also Pakistan and Nepal. This species is found in freshwater lakes, marshes, and ponds, and has also adapted well to reservoirs, human-made ponds, irrigation canals, and coastal saltwater lagoons. This crocodile likes shallow water no more than 5 m deep, and it avoids fast-flowing rivers. It will sometimes bury itself in the mud to avoid the searing heat in India in the dry season.

27-3-2025 YALA NAT PARK, SRI LANKA - INDIAN POND HERON (Ardeola grayii)

The Indian pond heron or paddybird (Ardeola grayii ) is a small heron. It is of Old World origins, breeding in southern Iran and east to the Indian subcontinent, Burma, and Sri Lanka. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations. They are however distinctive when they take off with bright white wings flashing in contrast to the cryptic streaked olive and brown colours of the body. Their camouflage is so excellent that they can be approached closely before they take to flight, a behaviour which has resulted in folk names and beliefs that the birds are short-sighted or blind.

The habit of standing still and flushing only at the last moment has led to widespread folk beliefs that they are semi-blind and their name in many languages includes such suggestions. In Sri Lanka the bird is called kana koka which translates as "half-blind heron" in the Sinhala language. The Hindustani phrase "bagla bhagat" has been used to describe a "wolf in sheep's clothing" or a hypocrite appearing like a meditating saint and occurs in a Marathi proverb. The paddy-bird also appears as a character in the Hitopadesha where, in one story, it takes injury to itself to save a king. The bird was noted by Anglo-Indian naturalist-writers for the surprising transformation in colours. Phil Robinson described the bird as one that sits all dingy gray and flies all white. It is said to have been eaten by many in India in former times.

During the height of the plume trade, feathers were collected from the "paddy bird" and exported to Britain.

27-3-2025 YALA NAT PARK, SRI LANKA - ASIAN COMMON TOAD (Duttaphrynus melanostictus)

Asian common toads occur widely from northern Pakistan through Nepal, Bangladesh, India including the Andaman and Nicobar Islands, Sri Lanka, Myanmar, Thailand, Laos, Vietnam, Cambodia, southern China, Taiwan, Hong Kong and Macau to Malaysia, Singapore, and the Indonesian islands of Sumatra, Java, Borneo, Anambas and Natuna Islands. They have been recorded from sea level up to 1,800 m (5,900 ft) altitude, and live mostly in disturbed lowland habitats, from upper beaches and riverbanks to human-dominated agricultural and urban areas. They are uncommon in closed forests.

27-3-2025 YALA NAT PARK, SRI LANKA - GREY BELLIED CUCKOO (Cacomantis passerinus)

The grey-bellied cuckoo or the Indian plaintive cuckoo (Cacomantis passerinus) is a cuckoo with widespread occurrence throughout Asia.

The grey-bellied cuckoo is one of the smaller cuckoos, at a total length of about 23 cm. Adults are mainly grey with a white lower belly and undertail. There is a white patch on the wings. Some females are dark-barred reddish brown above with an unbarred tail and have strongly dark-barred whitish underparts. The juvenile resembles the female but is of a duller grey.

The grey-bellied cuckoo breeds in tropical southern Asia from India and Sri Lanka to south China and Indonesia. It has been reported from Bangladesh, Bhutan, India, the Maldives, Myanmar, Nepal, Pakistan, and Sri Lanka. It is a short-distance migrant, since birds at more northerly latitudes and on higher ground are summer visitors, leaving for warmer areas in winter. The species prefers light woodland and cultivated areas.

The grey-bellied cuckoo is a brood parasite and uses warblers as hosts. It lays a single egg. Its diet consists of a variety of insects and caterpillars. This is a noisy species, with a persistent and loud pee-pip-pee-pee call, with its tail depressed.

The Grey-bellied Cuckoo has a broad range across tropical southern Asia, from India and Sri Lanka to southern China and Indonesia. It is known to inhabit countries such as Bangladesh, Bhutan, India, the Maldives, Myanmar, Nepal, Pakistan, and Sri Lanka. The bird is a short-distance migrant, with populations in the north and at higher elevations moving to warmer areas during the winter months.

The Grey-bellied Cuckoo is a brood parasite, laying its eggs in the nests of warblers. It is known for its persistent and loud vocalizations, often accompanied by a characteristic tail movement, with the tail being held in a depressed position.

The call of the Grey-bellied Cuckoo is a distinctive and repetitive pee-pip-pee-pee, which can be heard across its habitat.

Its diet is composed of a variety of insects and caterpillars, which it actively forages for.

27-3-2025 YALA NAT PARK, SRI LANKA - ORIENTAL DARTER (Anhinga melanogaster)

The Oriental darter (Anhinga melanogaster) is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body is submerged in water. It spears a fish underwater, bringing it above the surface, tossing and juggling it before swallowing the fish head first. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry.

The Oriental darter, Anhinga melanogaster, is a water bird of tropical South Asia and Southeast Asia. It is characterized by its long and slender neck, which is reminiscent of a snake, hence its colloquial name "snakebird." The bird's plumage is predominantly black with silvery streaks on the wing coverts and tertials. The underparts are blackish brown, and a pale line over the eye and throat, along with a line running along the sides of the neck, gives it a striped appearance.

Adult Oriental darters can be identified by their white iris with a yellow ring, a dark tip on the upper mandible, and yellowish lower mandible. The legs and webbing on the foot are yellow in immatures and non-breeding birds, while breeding birds have darker grey tarsi and toes with yellow webbing. In flight, the bird's long and slender neck, wide wings, and wedge-shaped tail make it distinctive.

The Oriental darter is typically found in freshwater lakes and streams, where it can be seen foraging alone with its body submerged and neck moving jerkily above the water.

This species is native to tropical regions of South Asia and Southeast Asia.

The Oriental darter hunts by submerging its body in water and darting its neck forward with rapid force to stab fish underwater. It then brings the fish to the surface, tossing it before swallowing head first. The bird is often seen perched on a rock or branch with wings held open to dry, as its feathers are wettable like those of cormorants. It may soar on thermals or alternate flapping and gliding in flight.

The Oriental darter is generally silent except at the nest, where it produces grunts and croaks, and a disyllabic "chigi-chigi-chigi." Chicks are noisy when begging for food.

Breeding occurs in mixed species heronries, where the Oriental darter builds a stick platform on a tree surrounded by water. The breeding season varies by region, with clutches typically consisting of three to six bluish-green eggs. Both parents incubate the eggs, leading to asynchronous hatching.

The Oriental darter's diet consists primarily of fish, which it spears underwater before swallowing.

26-3-2025 YALA NAT PARK, SRI LANKA - MALABAR PIED HORNBILL (Anthracoceros coronatus)

The Malabar pied hornbill (Anthracoceros coronatus), also known as the lesser pied hornbill, is a bird in the hornbill family, a family of tropical near-passerine birds found in the Old World.

The Malabar pied hornbill is a large hornbill, at 65 cm (26 in) in length. It has mainly black plumage, apart from its white belly, throat patch, tail sides and trailing edge to the wings. The bill is yellow with a large, mainly black casque. Females have white orbital skin, which the males lack. Juveniles have no casque. It might be confused with the oriental pied hornbill. They weigh around 1 kg (2.2 pounds).

The Malabar pied hornbill is a common resident breeder in India and Sri Lanka. Its habitat is evergreen and moist deciduous forests, often near human settlements. It is distributed across three main regions within the Indian sub-continent: Central and Eastern India, along the Western Ghats, and in Sri Lanka. In Central and Eastern India, it ranges from western West Bengal through parts of Jharkhand, Chhattisgarh, Odisha, Madhya Pradesh, northern and eastern Maharashtra, northern Andhra Pradesh, and north-east tip of Telangana. Along the Western Ghats, the species is distributed in pockets along the eastern slopes and in the Konkan belt and west coast from western Maharashtra through Goa, western Karnataka and Tamil Nadu, and in Kerala. In Sri Lanka, the species occurs mainly in the low country and dry zone forests as well as home gardens.

The Malabar pied hornbill exhibits fascinating breeding behaviour. The female lays two to three white eggs in a tree hole, which is then sealed with a mixture of mud, droppings, and fruit pulp, leaving only a narrow aperture. Through this opening, the male provides food to the female and the chicks. Once the chicks grow, the female breaks out to assist in feeding them.

The oriental pied hornbill is similar in appearance but can be differentiated by careful observation of the birds' distinct physical characteristics.

An omnivorous bird, the Malabar pied hornbill's diet consists of fruits, small mammals, birds, small reptiles, and insects. Figs are a staple, making up a significant portion of their diet, especially outside the breeding season. They also consume other fruits, including those of the Strychnos nux-vomica, which are toxic to many vertebrates.

26-3-2025 YALA NAT PARK, SRI LANKA - INDIAN PARADISE FLYCATCHER (FEMALE)

The Indian paradise flycatcher (Terpsiphone paradisi) is a medium-sized passerine bird native to Asia, where it is widely distributed. As the global population is considered stable, it has been listed as Least Concern on the IUCN Red List since 2004. It is native to the Indian subcontinent, Central Asia and Myanmar.

Males have elongated central tail feathers, and a black and rufous plumage in some populations, while others have white plumage. Females are short-tailed with rufous wings and a black head. Indian paradise flycatchers feed on insects, which they capture in the air often below a densely canopied tree.

Indian paradise flycatchers are usually seen singly or in pairs. They are active during the daylight hours spending most of their time foraging. They catch insects in the air often below a densely canopied tree. They move quickly between the branches and are mainly arboreal. Indian paradise flycatchers may sometimes gather in mixed flocks. They communicate with each other using various calls and songs.

Indian paradise flycatchers are socially monogamous; they form pairs in which both males and females take part in nest-building, incubation, brooding, and feeding of the young. They breed from May to July. The nest is sometimes built in the vicinity of a breeding pair of drongos, which keep predators away. The female lays up to 4 eggs in a neat cup nest made with twigs and spider webs on the end of a low branch. Chicks hatch in about 14-16 days. They are altricial (blind and helpless) and stay in the nest for 9 to 12 days.

26-3-2025 YALA NAT PARK, SRI LANKA - BLACK HOODED ORIOLE (Oriolus xanthornus)

The male is striking, with the typical oriole black and yellow colouration. The plumage is predominantly yellow, with a solid black hood, and black also in the wings and tail centre.

The female black-hooded oriole is a drabber bird with greenish underparts, but still has the black hood. Young birds are like the female, but have dark streaking on the underparts, and their hood is not solidly black, especially on the throat.

The black head of this species is an obvious distinction from the Indian golden oriole, which is a summer visitor to northern India. Orioles can be shy, and even the male may be difficult to see in the dappled yellow and green leaves of the canopy.

The black-hooded oriole's flight is somewhat like a thrush, strong and direct with some shallow dips over longer distances. 

Black-hooded orioles are shy, and even the male may be difficult to see in the dappled yellow and green leaves of the canopy. Their flight is somewhat like a thrush, strong and direct with some shallow dips over longer distances. Black-hooded orioles are diurnal and while foraging they use foliage-gleaning, wood-gleaning, or sallying methods.

Little is known about the reproductive habits of Black-hooded orioles. They construct their nests in a tree, and females lay clutches of 2 eggs.

Black-hooded orioles breed from India and Sri Lanka east to Indonesia. They live in open woodlands, mangroves and cultivated areas.
