22-3-2025 GAL OYA, SRILANKA - WHITE BREASTED WATERHEN (Amaurornis phoenicurus)

The white-breasted waterhen (Amaurornis phoenicurus) is a waterbird of the rail and crake family, Rallidae, that is widely distributed across South and Southeast Asia. They are dark slaty birds with a clean white face, breast and belly. They are somewhat bolder than most other rails and are often seen stepping slowly with their tail cocked upright in open marshes or even drains near busy roads. They are largely crepuscular in activity and during the breeding season, just after the first rains, make loud and repetitive croaking calls.

Adult white-breasted waterhens have mainly dark grey upperparts and flanks, and a white face, neck and breast. The lower belly and undertail are cinnamon or white coloured. The body is flattened laterally to allow easier passage through the reeds or undergrowth. They have long toes, a short tail and a yellow bill and legs. Sexes are similar but females measure slightly smaller. Immature birds are much duller versions of the adults. The downy chicks are black, as with all rails. 

Several subspecies are named for the populations that are widely distributed. The nominate subspecies is described from Sri Lanka but is often widened to include chinensis of mainland India and adjoining regions in Asia, west to Arabia and east nearly to Japan. The remaining subspecies are those from islands and include insularis of the Andaman and Nicobar Islands, midnicobaricus of the central Nicobars, leucocephala of Car Nicobar, maldivus of the Maldives, javanicus of Java and leucomelanus of Sulawesi and the Lesser Sundas.

Their breeding habitat is marshes across tropical Asia from Pakistan east to Indonesia. They are mainly seen in the plains but have been known from the higher hills such as in Nainital (1300m) and the High Range (1500m) in Kerala. These large 32 cm (13 in) long rails are permanent residents throughout their range. They make short distance movements and are known to colonize new areas. They have been noted as some of the early colonizers on the volcanic island of Rakata. Although most often found near freshwater, they are also found near brackish water and even the seashore when there is no freshwater as on the volcanic Barren Island in the Andamans.

3-4-2025 WALLAWWA LODGE, SRI LANKA - COMMON HOUR GLASS TREE FROG (Polypedates cruciger)

Polypedates cruciger (commonly known as the Sri Lanka whipping frog or common hour-glass tree-frog) is a species of frog in the family Rhacophoridae endemic to Sri Lanka. It has been osbserved as high as 1600 meters above sea level.

This frog can tolerate different habitats, including secondary forest, banana farms, gardens, and buildings. Scientists have not seen this frog in primary forest.

Scientists say this frog is not in danger of dying out because of its large range and tolerance to altered habitat.

Scientists used to think frog was conspecific with Polypedates pseudocruciger, which lives in India's Western Ghat mountains. 

18-3-2025 WATER GARDENS LODGE SIGIRIYA, SRI LANKA - LAND MONITOR (Varanus bengalensis)

The Bengal monitor (Varanus bengalensis), also called the Indian monitor, is a species of monitor lizard distributed widely in the Indian subcontinent, as well as parts of Southeast Asia and West Asia.

Juveniles are patterned and more colourful

The Bengal monitor can reach 175 cm (69 in) with a snout-to-vent length (SVL) of 75 cm (30 in) and a tail of 100 cm (39 in). Males are generally larger than females. Heavy individuals may weigh nearly 7.2 kg (16 lb).

The populations of monitors in India and Sri Lanka differ in the scalation from those of Myanmar; these populations were once considered subspecies of the Bengal monitor, but are now considered two species within the V. bengalensis species complex. What was once the nominate subspecies, V. bengalensis, is found west of Myanmar, while the clouded monitor (V. nebulosus) is found to the east. Clouded monitors can be differentiated by the presence of a series of enlarged scales in the supraocular region. The number of ventral scales varies, decreasing from 108 in the west to 75 in the east (Java).

Young monitor lizards are more colourful than adults. Young have a series of dark crossbars on the neck, throat and back. The belly is white, banded with dark crossbars and are spotted with grey or yellow (particularly in the eastern part of the range). On the dorsal surface of young monitors, there are a series of yellow spots with dark transverse bars connecting them. As they mature, the ground colour becomes light brown or grey, and dark spots give them a speckled appearance. Clouded monitor hatchlings by comparison tend to have a series of backward-pointing, V-shaped bands on their necks.

Bengal monitors have external nostril openings (nares) that is slit-like and oriented near horizontal, and positions between the eye and the tip of the snout. The nares can be closed at will, especially to keep away debris or water. The scales of the skin are rougher in patches and on the sides, they have minute pits, especially well distributed in males. These scales with micropores have glandular structures in the underlying dermal tissue and produce a secretion which may be a pheromone-like substance. Like other monitors, Bengal monitors have a forked tongue similar to snakes. The function is mainly sensory, and is not very involved in the transport of food down the throat. Bengal monitors have fat deposits in the tail and body that serve them in conditions when prey are not easily available.

18-3-2025 WATER GARDENS LODGE SIGIRIYA, 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 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.

Indian pond herons are stocky with short necks, short thick bills and buff-brown backs. In summer, adults have long neck feathers. Their appearance is transformed from dull colours when they take to flight and the white of the wings makes them very prominent. They are very similar to the squacco herons, Ardeola ralloides, but darker backed. To the east of their range, they are replaced by the Chinese pond herons, Ardeola bacchus.

During the breeding season, there are records of individuals with red legs. The numbers do not suggest that this is a normal change for adults during the breeding season and some have suggested the possibility of it being genetic variants.

Erythristic plumage has been noted. The race phillipsi has been suggested for the populations found in the Maldives, without much acceptance. It forms a superspecies with the closely related Chinese pond heron, Javan pond heron and the Madagascar pond heron.

They are usually silent but may make a harsh croak in alarm when flushed or near their nests.

18-3-2025 WATER GARDENS LODGE SIGIRIYA, SRI LANKA - INDIAN PEAFOWL (MALE) (Pavo cristatus),

The Indian peafowl (Pavo cristatus), also known as the common peafowl, or blue peafowl, is a peafowl species native to the Indian subcontinent. While it originated in the Indian subcontinent, it has since been introduced to many other parts of the world. Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens, although both sexes are often referred to colloquially as a "peacock".

The Indian peafowl displays a marked form of sexual dimorphism. The brightly coloured male has a blue coloured head with a fan-shaped crest and is best known for their long train. The train is made up of elongated upper-tail covert feathers with colourful eyespots. These stiff feathers are raised into a fan and quivered in a display during courtship. The peahen is predominantly brown in colour, with a white face and iridescent green lower neck, and lack the elaborate train. There are several colour mutations of the Indian peafowl including the leucistic white peafowl. 

Despite the length and size of the covert feathers, the peacock is still capable of flight. The peafowl lives mainly on the ground in open forests or on cultivable lands where it forages for berries and grains, and also preys on snakes, lizards and small rodents. It makes loud calls, which makes it easier to detect, and are often used to indicate the presence of a predator in the forest areas. It forages on the ground in small groups and usually escapes on foot through undergrowth and avoids flying, though it flies into tall trees to roost.

The function of the Indian peacock's elaborate train has been debated for more than a century. In the 19th century, Charles Darwin found it a puzzle, hard to explain through ordinary natural selection. His later explanation, sexual selection, is widely but not universally accepted. In the 20th century, Amotz Zahavi argued that the train was a handicap, and that males were honestly signalling their fitness in proportion to the splendour of their trains. Despite extensive study, opinions remain divided on the mechanisms involved.

The Indian peafowl is listed as Least Concern on the IUC

17-3-2025 COLOMBO CITY, SRI LANKA - QUEEN'S WREATH (Petrea volubilis)

Petrea volubilis, commonly known as purple wreath, queen's wreath or sandpaper vine, is an evergreen flowering vine in the family Verbenaceae, native to tropical America, that is valued especially for its display of violet flowers.

As a climbing plant, it grows to a height of 12 m (39 ft), but as a shrub it grows to 4 m (13 ft) tall. It is a vine or semi-climbing shrub with puberulent stems, sometimes reaching 10 cm (3.9 in) in diameter. Leaves are elliptical-oblong, 5–16cm long and 3–8cm wide, apex acute or obtuse, base wedge-shaped, entire margin, sometimes sinuous, glabrous or pubescent, rough to the touch; petiole 0.2–1 cm long.

The flowers emerge from bracts. Racemose inflorescences 8–20 cm long, axillary or terminal, solitary, puberulent rachis, 5-mere flowers on puberulent pedicels supported by a deciduous bract ; calyx tube 0.2–0.7 cm long, glabrous or puberulent, corolla infundibuliform, 1 cm long, puberulent, blue; ovary and glabrous style. Drupaceous fruit completely enclosed in the acrid calyx which acts as wings or floats.

It is found especially on the banks of rivers and streams, from northern Mexico to Bolivia, Brazil and Paraguay in the Antilles and in Venezuela. Depending on the climate, it can have up to two blooms in the year. Its very nectar-bearing flowers attract butterflies.

2-4-2025 CONCORDIA ESTATE GOATFELL, SRI LANKA - ASHY PRINIA (Prinia socialis)

The ashy prinia or ashy wren-warbler (Prinia socialis) is a small warbler in the family Cisticolidae. This prinia is a resident breeder in the Indian subcontinent, ranging across most of India, Nepal, Bangladesh, eastern Pakistan, Bhutan, Sri Lanka and western Myanmar. It is a common bird in urban gardens and farmlands in many parts of India and its small size, distinctive colours and upright tail make it easy to identify. The northern populations have a rufous rump and back and have a distinct breeding and non-breeding plumage while other populations lack such variation.

These 13–14 cm long warblers have short rounded wings and a longish graduated cream tail tipped with black subterminal spots. The tail is usually held upright and the strong legs are used for clambering about and hopping on the ground. They have a short black bill. The crown is grey and the underparts are rufous in most plumages. In breeding plumage, adults of the northern population are ash grey above, with a black crown and cheek with no supercilium and coppery brown wings. In non-breeding season, this population has a short and narrow white supercilium and the tail is longer. They are found singly or in pairs in shrubbery and will often visit the ground. 

In winter, the northern subspecies, P. s. stewartii Blyth, 1847, has warm brown upperparts and a longer tail and has seasonal variation in plumage. The other races retain summer plumage all year round. West Bengal and eastwards has the race inglisi Whistler & Kinnear, 1933, which is slatier above than the nominate race of the Peninsula and deeper rufous on the flanks with a finer and shorter beak. The distinctive endemic race in Sri Lanka, P. s. brevicauda Legge, 1879, has a shorter tail and the juveniles have yellowish underparts apart from a distinct call. This passerine bird is found in dry open grassland, open woodland, scrub and in home gardens in many cities. The northern limits of the species are along the Himalayan foothills extending into the upper Indus river system. The species is absent from the dry desert zone of the west of India and extends east into Burma. The Sri Lankan population is found mainly in the lowlands but going up into the hills to about 1600 m.

Like most warblers, the ashy prinia is insectivorous. Their song is a repetitive tchup, tchup, tchup or zeet-zeet-zeet. Another call is a nasal tee-tee-tee. It also makes a sound like "electric sparks" during its fluttery flight, which is thought to be produced by the wings, although one author suggests that it is made by the beak.

16-3-2025 ISHQ COLOMBO, SRI LANKA - RED WATER LILY (Nymphaea rubra)

Nymphaea rubra is a species of waterlily native to the region spanning from Sri Lanka and northeastern India to western and central Malesia. Additionally, it has been introduced to regions such as Southeast China, Cuba, Guyana, Hungary, and Suriname.

Nymphaea rubra has 15.1 cm long, and 7.9 cm wide rhizomes. The petiolate, orbicular leaves are 25–48 cm wide. The adaxial leaf surface is bronzy red to dark green, and the abaxial leaf surface is dark purple. The leaf venation is very prominent. The petiole is 140 cm long.

The flowers are 15–25 cm wide. The four purplish-red sepals are oblong to lanceolate. The 12-20 narrowly oval petals have a rounded apex. The androecium consists of 55 red stamens. The gynoecium consists of 16-21 carpels. The fruit bears 1.85 mm long, and 1.6 mm wide seeds. The peduncle is 116 cm long. The flowers are pleasantly fragrant.

1-4-2025 GOATFELL LODGE, SRI LANKA - SLUG CATERPILLAR MOTH (Oxyplax pallivittal)

A moth found in Sri Lanka which creates a caterpillar. Oxyplax pallivitta, also known as the nettle caterpillar or stinging nettle caterpillar, is a serious invasive pest of agricultural products and a health hazard on the Hawaiian Islands, characterized by larvae containing urticating hairs that causepainful skin swelling and irritation. 

1-4-2025 PEDRO TEA PLANTATION, SRI LANKA - LARGE BILLED CROW (Corvus macrorhynchos)

The large-billed crow (Corvus macrorhynchos ), formerly referred to widely as the jungle crow, is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill, which is the source of its scientific name macrorhynchos (Ancient Greek for "large beak") and it is sometimes known by the common name thick-billed crow. It can also be mistaken for a common raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827. The eastern jungle crow and Indian jungle crow were once considered conspecific and together called the jungle crow.

1-4-2025 GOATFELL LODGE, SRI LANKA - THREE STRIPED PALM SQUIRREL (Funambulus palmarum)

The Indian palm squirrel or three-striped palm squirrel (Funambulus palmarum) is a species of rodent in the family Sciuridae found naturally in India (south of the Vindhyas) and Sri Lanka. In the late 19th century, the palm squirrel was introduced to Madagascar, Réunion, Mayotte, Comoro Islands, Mauritius, and Seychelles. The closely related five-striped palm squirrel, F. pennantii, is found in northern India, and its range partly overlaps with this species.

The palm squirrel is about the size of a large chipmunk, with a bushy tail slightly shorter than its body. The back is a grizzled, grey-brown colour with three conspicuous white stripes which run from head to tail. The two outer stripes run from the forelegs to the hind legs only. It has a creamy-white belly and a tail covered with interspersed, long, black and white hair. The ears are small and triangular. Juvenile squirrels have significantly lighter coloration, which gets progressively darker as they age. Albinism is rare, but exists in this species.

The Indian palm squirrel exhibits a variety of reproductive behaviors; some display cyclical periodicity activity while others show continuous reproductive activity. The gestation period is 34 days; breeding takes place in grass nests during the autumn. Litters of two or three are common, and average 2.75. The young are weaned after about 10 weeks and are sexually mature at 9 months. The adult weight is 100 grams. Little is known about their longevity, but one specimen lived 5.5 years in captivity.

2-4-2025 CONCORDIA ESTATE GOATFELL, SRI LANKA - SRI LANKA WHITE-EYE (Zosterops ceylonensis)

The Sri Lanka white-eye (Zosterops ceylonensis) is a small passerine bird in the white-eye family, which is endemic to Sri Lanka. It is a resident breeder in forests, gardens and plantations, mainly in the highlands.

A study showed that it is not sister to the other Sri Lankan species, the Indian White-eye (Zosterops palpebrosus), and it also suggested that it is the root species which gave rise to all white-eyes on Earth. This raises further questions on white-eye origins.

This bird is slightly larger than the Indian white-eye (about 11 cm long) which it replaces above 4000 ft. The upper parts of the body and sides of neck are dark olive-green. The rump appears paler green while the crown and forehead appear darker. The wings and tail are brown edged with green on the back. The typical ring of tiny white feathers around the eye is present. The lores are dark and there is a dark streak below the eye. The chin, throat and upper breast are greenish-yellow as are the thighs and vent. The belly region is greyish white. The dark bill has a slaty base to the lower mandible. The legs are dark. The iris is yellow to reddish-brown.

This species can be distinguished from the widespread Indian white-eye, Zosterops palpebrosus, by its larger size, duller green back and more extensive yellow on the breast. It has a darker patch between the eye and the bill.

It is sociable, forming large flocks which only disperse with the approach of the breeding season. It builds a tree nest and lays 3 unspotted pale blue eggs.

Though mainly insectivorous, the Sri Lankan white-eye will also eat nectar and fruits of various kinds.

The English and scientific names refer to the conspicuous ring of white feathers around the eyes, Zosterops being Greek for "girdle-eye".

In Sri Lanka, this bird is known as Lanka Sithasiya in the Sinhala language. This bird appears on a 35c Sri Lankan postage stamp first issued in 1983.

1-4-2025 MEDAHINNA, SRI LANKA - CEYLON BLUE OAKLEAF BUTTERFLY (Kallima philarchus)

Kallima philarchus, the Ceylon blue oakleaf, is a nymphalid butterfly found in Sri Lanka. With wings closed, it closely resembles a dry leaf with dark veins and is a spectacular example of camouflage.

The Sri Lankan Blue Oak Leaf only feeds on overripe fruits and tree sap. Males perch on foliage in an opening at a stream to search for mates. This is a migrant species.

This is an iconic butterfly in gloomy wet zone forests, only coming out in openings within forests. Its distribution extends to the intermediate zone and occasionally to dry zone forests along shady streams.  

26-3-2025 YALA NAT PARK, SRI LANKA - BLACK NAPED HARE (Lepus nigricollis)

The Indian hare (Lepus nigricollis), also known as the black-naped hare, is a common species of hare native to the Indian subcontinent, and Java. Its habitat in Java is in rocky highlands.

The Indian hare has a head and body length of 40–60 cm (16–24 in), long ears, large, well-furred hind feet, and a rather long tail of about 10 cm (3.9 in) and weighs up to 6 kg (13 lb).

The Indian hare inhabits open grassy areas, cultivated plains, semi-arid and arid plains, and hills throughout the Indian subcontinent and Sri Lanka.

Its activity pattern has been defined as crepuscular and nocturnal.[citation needed]

It has been introduced to Madagascar, Comoro Islands, Andaman Islands, Western New Guinea, Papua New Guinea, Seychelles, Mayotte, Mauritius and Réunion.

Lepus nigricollis are generally found in areas where large tracts of bush and jungle alternate with farmland. They are also commonly sighted in coastal herb communities. Hilly areas, particularly the depressions at the base of hills, are preferred habitats for L. nigricollis.

Lepus nigricollis are also called black-naped hares due to the patch of black fur that runs along the nape of the neck. The top of the tail is also black and the back and face are brown with black hairs scattered throughout. The underparts are white. Total length ranges from 40 to 70 cm and weight ranges from 1.35 to 7 kg.

Like all hares, they have long ears and large hind feet which are well furred. There is some evidence that hares that have been introduced to islands are smaller than those in mainland India. Regardless of location, female L. nigricollis tend to be larger than males.

During mating season, male L. nigricollis become aggressive, sparring with other males using their forepaws and "boxing" with their hind feet. Males will attempt to mate with as many females as they can.

Reproduction rates tend to be at their highest during the wet season, though L. nigricollis will generally breed year round. The increased rate of reproduction is likely the result of an increase in nutrient rich foods. On average, 69% of adult females are pregnant every year. In L. nigricollis dayanus, a subspecies of Indian hare, reproduction is also dependent on the length of the day. One to eight young are born after a gestation period of 41 to 47 days. Sexual maturity occurs in the year following birth.

27-3-2025 YALA NAT PARK, SRI LANKA - SRI LANKA JUNGLEFOWL (Gallus lafayettii)

The Sri Lankan junglefowl (Gallus lafayettii sometimes spelled Gallus lafayetii), also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order .It is a common endemic bird in Sri Lanka, where it is the national bird. It is closely related to the red junglefowl (G. gallus), the wild junglefowl from which the chicken was domesticated. However, it is even more closely related to the grey junglefowl. Sri Lankan junglefowl and red junglefowl diverged about 2.8 million years ago, whereas time of divergence between the Sri Lankan junglefowl and grey junglefowl was 1.8 million years ago.

Evidence of introgressive hybridization from Sri Lanka junglefowl has also been established in domestic chicken. The specific name of the Sri Lankan junglefowl commemorates the French aristocrat Gilbert du Motier, marquis de La Fayette (1757–1834). 

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.

The Yellow-billed Babbler, Argya affinis, is a bird of modest charm, with its grey-brown plumage and a gentle demeanor. It is a resident breeder endemic to the verdant landscapes of southern India and Sri Lanka, where it flits about in scrublands, gardens, and cultivated areas. This species is distinguished by its pale buff belly, grey throat, and breast with subtle mottling, and a head graced with a grey hue. The eyes of this bird are a striking bluish white, adding a touch of intrigue to its otherwise understated appearance.

To identify the Yellow-billed Babbler, look for the whitish crown and nape in the southern Indian subspecies, contrasted with a darker mantle and a broad dark tip on the tail. The Sri Lankan subspecies, A. a. taprobanus, presents a drab pale grey, blending seamlessly with its surroundings. The Indian form is more heavily streaked on the throat and breast, providing a helpful clue for differentiation.

The Yellow-billed Babbler favors lower altitudes and drier habitats than its cousin, the Jungle Babbler. It thrives in areas where human activity has sculpted the landscape, including gardens and urban environments, bringing a touch of the wild to our doorsteps.

This species is patchily distributed across southern India and Sri Lanka. In India, it is found from Andhra Pradesh, south of the Godavari river, and Karnataka south of Belgaum into Tamil Nadu. The Sri Lankan subspecies inhabits the lowlands and hills up to about 1500 meters, avoiding dense forests.

The Yellow-billed Babbler is a gregarious creature, living in flocks that fill the air with their incessant chatter. They forage together, with one acting as a sentinel perched high while others search for food on or near the ground. Their diet is eclectic, ranging from insects to fruit, nectar, and even human food scraps. These birds are not known for their flying prowess, preferring short flights and often gaining altitude through trees or tall shrubs before taking off.

The Yellow-billed Babbler's vocal repertoire includes seven distinctive calls, higher pitched than those of the Jungle Babbler. Its calls lack the harsh, nasal quality of its relative, instead offering a more melodious contribution to the soundscape.

Breeding season peaks before the monsoon, with nests built in trees, hidden among dense foliage. The nests are small cups, often below four meters from the ground. Clutches typically contain two to four turquoise blue eggs, with incubation lasting 14 to 16 days. Brood parasitism by the Pied Cuckoo and the Common Hawk-cuckoo has been recorded.

The Yellow-billed Babbler can be confused with the Jungle Babbler, especially where their ranges overlap. However, the Yellow-billed Babbler's distinctive call and preference for more vegetated habitats can help distinguish between the two.

These babblers are insectivorous but have a varied diet that includes fruit, nectar, and occasionally human food scraps. They have been observed preying on small lizards and whip-scorpions, showcasing their adaptability in foraging.

The IUCN Red List classifies the Yellow-billed Babbler as Least Concern, indicating a stable population that does not currently face significant threats to its survival.

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.
