12-3-2020 KERALA, INDIA - BLUE TAILED BEE-EATER (Merops philippinus)
%2020.jpg)
The Blue-tailed Bee-eater, Merops philippinus, is a near passerine bird belonging to the family Meropidae. It is a slender bird with a rich palette of colors, predominantly green with a blue tail. The face features a narrow blue patch with a black eye stripe, and the throat is a mix of yellow and brown. Notably, the beak is black, and the three outer toes are fused at the base. Both sexes are similar in appearance, with a body length of 23–26 cm, including the elongated central tail feathers.
When identifying the Blue-tailed Bee-eater, look for the blue rather than green rump and tail, distinguishing it from the similar Blue-cheeked Bee-eater. The under-tail coverts are bluish, and the blue cheek patch is smaller. The chestnut on the throat and breast is darker and more extensive.
This species is typically found in open habitats near water bodies.

The Blue-tailed Bee-eater has a widespread distribution across South and Southeast Asia. It is migratory in many parts of its range, with breeding colonies often found in river valleys.
These birds are known for their colonial breeding habits, nesting in close proximity within vertical mudbanks or sloping land. They exhibit communal feeding and roosting behaviors and may have helpers assisting the breeding pair.
The Blue-tailed Bee-eater's call is a rolling chirping whistle, described as a "teerp," primarily heard during flight.
%2022.jpg)
Breeding occurs from April to May in India, with nests tunneled into loamy sand banks. The species lays 5 to 7 near-spherical eggs, with both parents involved in care. They guard against brood parasitism and extra-pair copulation.
The Blue-cheeked Bee-eater is the most similar species within its range but can be differentiated by its drier habitat preference and distinct coloration differences.
The diet consists mainly of flying insects such as bees, wasps, and hornets, which are caught in the air from an open perch. The insects are beaten on the perch to kill them and break the exoskeleton.
The Blue-tailed Bee-eater is listed as Least Concern by the International Union for Conservation of Nature (IUCN), indicating a stable population.
14-3-2020 KERALA, INDIA - GOLDEN TRUMPET (Allamanda cathartica)
Allamanda cathartica, commonly called golden trumpet, common trumpetvine, and yellow allamanda, is a species of flowering plant in the family Apocynaceae. It is native to Bolivia, Brazil, French Guiana, Guyana, Suriname, and Venezuela, and widely naturalised elsewhere in the tropics. This plant is cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius.
It does not twine, nor does it have tendrils or aerial roots. It can be pruned into a shrub form. If not pruned it can sprawl to a height of 6 m (20 ft). According to McMullen, it can be up to 15 m (49 ft) in length in the Galapagos Islands where it is naturalised.
The city of Canóvanas, Puerto Rico has adopted this species, known locally as canario amarillo, as its official flower.
The species is cultivated as a house plant. It requires a soil rich in organic matter, temperatures of not less than 18 °C (64 °F) during the growing season, plenty of moisture, and bright light but not direct sunlight. During the rest season from October to March, the plant should be watered more sparingly and can endure temperatures down to 13 °C (55 °F). It should be repotted every year until it is in a container of 40–50 cm (16–20 in). Propagation is by cuttings taken from April to May.
14-3-2020 KERALA, INDIA - CROWN FLOWER (Calotropis gigantea)
Calotropis gigantea, the crown flower, is a species of Calotropis native to Cambodia, Vietnam, Bangladesh, Indonesia, Malaysia, Philippines,Thailand, Sri Lanka, India, China, Pakistan, and Nepal.
It is a large shrub growing to 4 m (13 ft) tall. It has clusters of waxy flowers that are either white or lavender in colour. Each flower consists of five pointed petals and a small "crown" rising from the center which holds the stamens. The aestivation found in calotropis is valvate i.e. sepals or petals in a whorl just touch one another at the margin, without overlapping. The plant has oval, light green leaves and milky stem. The latex of Calotropis gigantea contains cardiac glycosides, fatty acids, and calcium oxalate. The roots also contain Calotropone.
14-3-2020 KERALA, INDIA - PIED PADDY SKIMMER DRAGONFLY (Neurothemis tullia)
Neurothemis tullia, the pied paddy skimmer, is a species of dragonfly found in south and south-east Asia. It appears in Bangladesh, China, Hong Kong, India, Malaysia (Peninsular Malaysia), Myanmar, Nepal, Sri Lanka, Taiwan, Thailand, Cambodia and Viet Nam.
It is a black dragonfly with a pale yellow mid-dorsal carina of thorax. Wings are hyaline for apical half and opaque steely blue-black for basal half which is bordered by a milky white patch towards the tip. Females differ remarkably from the males both in body-colouring and markings and in marking of the wings. Its body is greenish yellow with a bright yellow mid-dorsal carina of thorax. Base of wings are amber yellow followed by a blackish brown patch. Apices of all wings are broadly opaque blackish brown and the remaining halves are pale yellow.
It breeds in marshes, well vegetated ponds, lakes and rice fields. It perches very close to ground and its flight is very weak.
14-3-2020 KERALA, INDIA - BAYA WEAVER (Ploceus philippinus)
The baya weaver (Ploceus philippinus) is a weaverbird found across the Indian Subcontinent and Southeast Asia. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability.
Among the population variations, five subspecies are recognized. The nominate race P. p. philippinus is found through much of mainland India while P. p. burmanicus is found eastwards into Southeast Asia. The population in southwest India is darker above and referred to as subspecies P. p. travancoreensis.
Baya weavers are social and gregarious birds. They forage in flocks for seeds, both on the plants and on the ground. Flocks fly in close formations, often performing complicated manoeuvres. They are known to glean paddy and other grain in harvested fields, and occasionally damage ripening crops and are therefore sometimes considered as pests. They roost in reed-beds bordering waterbodies. They depend on wild grasses such as Guinea grass (Panicum maximum) as well as crops like rice for both their food (feeding on seedlings in the germination stage as well as on early stages of grain) and nesting material.
They also feed on insects (including butterflies[, sometimes taking small frogs, geckos and molluscs, especially to feed their young. Their seasonal movements are governed by food availability. Their calls are a continuous chit-chit-... sometimes ending in a wheezy cheee-eee-ee that is produced by males in a chorus. A lower intensity call is produced in the non-breeding season.
They are occasionally known to descend to the ground and indulge in dust bathing.
In captivity, individuals are known to form stable peck orders.
14-3-2020 TURTLE BEECH KERALA, INDIA - PHILIPPINE GROUND ORCHID (Spathoglottis plicata)
Spathoglottis plicata, commonly known as the Philippine ground orchid, or large purple orchid is an evergreen, terrestrial plant with crowded pseudobulbs, three or four large, pleated leaves and up to forty resupinate, pink to purple flowers. It is found from tropical and subtropical Asia to Australia and the western Pacific including Tonga and Samoa.
Spathoglottis plicata is an evergreen, terrestrial herb that forms tall clumps. It has crowded pseudobulbs 40–60 mm (1.6–2.4 in) long and 20–40 mm (0.8–2 in) wide, each with three or four pleated leaves 50–90 mm (2–4 in) long and 8–15 mm (0.3–0.6 in) wide on a stalk 80–150 mm (3–6 in) long. Up to forty deep pink to purple resupinate flowers 35–55 mm (1–2 in) long and wide are borne on a hairy flowering stem 50–100 cm (20–40 in) tall. The dorsal sepal is 20–30 mm (0.8–1 in) long and the lateral sepals are slightly narrower. The petals are about the same length as the sepals but significantly wider. The labellum is T-shaped, a similar size to the dorsal sepal and has three lobes with the side lobes close to vertical. At the tip of the column there is a cap, under which masses of yellow pollen grains can be seen.
Flowering occurs from September to April in Australia and in most months in China and New Guinea. The fruit is a capsule about 3 mm (0.1 in) long, green and cylindrical. After the flower is fertilized, the seeds take about six weeks to develop. When ripe, the capsule splits open and thousands of tiny seeds are carried away by wind.
14-3-2020 TURTLE BEECH KERALA, INDIA - COMMON PICTURE WING DRAGONFLY (Rhyothemis variegata)
Rhyothemis variegata, known as the common picture wing, variegated flutterer, yellow-striped flutterer or yellow-barred flutterer, is a species of dragonfly of the family Libellulidae, found in South Asia, Indochina, southern China, Indonesia, Papua New Guinea, Australia and islands in the Pacific Ocean.
Rhyothemis variegata is a medium-sized dark bodied dragonfly with colorful wings tinted with pale yellow. There are a few black spots on the apices and nodes of the fore-wings. There is a large patch in the base of the hind-wings, marked with black and golden yellow. In females, the apical half of the fore-wings are transparent; basal half tinted with golden-yellow with black marks. The apical ends of the hind-wings are transparent; rest of wings marked with golden-yellow and black.
It breeds in marshes, ponds and paddy fields. They appear to have weak flight and can easily be mistaken for butterflies.
13-3-2020 TURTLE BEECH KERALA, INDIA - TAWNY COSTER BUTTERFLY (Acraea terpsicore)
Acraea terpsicore, the tawny coster, is a small, 53–64 millimetres (2.1–2.5 in), leathery-winged butterfly common in grassland and scrub habitats. It belongs to the Nymphalidae or brush-footed butterfly family. It has a weak fluttery flight. It is avoided by most insect predators. This species and the yellow coster (Acraea issoria) are the only two Indian representatives of the predominantly African tribe Acraeini. It is found in India, Sri Lanka, Maldives to Myanmar, Thailand, Laos, Cambodia, Vietnam, Bangladesh, Singapore, and recently Australia.
This species does not fly high, but seems to keep within 3 m of the ground and tends to rest on vegetation in the regions of a meter off the ground. Acraea terpsicore can be seen in abundance wherever its larval food plant (Passiflora species) is found. The adult tends to avoid dense undergrowth and shady areas, instead keeping to open spaces in all types of vegetation.
The adult flies slowly with weak seemingly unsteady wing beats. It is one of the boldest butterflies, protected as it is from predators by a nauseous chemical. When attacked it plays dead and exudes a noxious yellowish fluid from glands in the joints of the legs. Like all butterflies protected in this manner, Acraea terpsicore has a tough exoskeleton which enables the adult to survive a few pecks of a bird or even the bites of a lizard. Once left alone the adult immediately takes off and resumes its uncaring flight.
When feeding on flowers, this butterfly is unhurried, often spending a long time sitting on the same flower. When sitting it either spreads its wings or closes them over its back the hindwings covering the forewings to a large extent. Sometimes the butterfly will not sit, but rest gently on the flower while feeding, while doing this, to maintain balance, it beats only its forewings while keeping the hindwings completely steady.
14-3-2020 TURTLE BEECH KERALA, INDIA - SCARLET SKIMMER DRAGONFLY (MALE) (Crocothemis servilia)
%20(Crocothemis%20servilia)%2020.jpg)
The scarlet skimmer or ruddy marsh skimmer, Crocothemis servilia, is a species of dragonfly of the family Libellulidae, native to east and southeast Asia and introduced to Jamaica, Florida, and Hawaii.
It is a medium sized blood-red dragonfly with a thin black line along the mid-dorsal abdomen. Its eyes are blood-red above, purple laterally. Thorax is bright ferruginous, often blood-red on dorsum. Abdomen is blood-red, with a narrow black mid-dorsal carina. Anal appendages are blood-red. Female is similar to the male; but with olivaceous-brown thorax and abdomen. The black mid-dorsal carina is rather broad.
It breeds in ponds, ditches, marshes, open swamps and rice fields.

13-3-2020 TURTLE BEECH KERALA, INDIA - PLAIN TIGER BUTTERFLY (Danaus chrysippus)
Danaus chrysippus, also known as the plain tiger, African queen, or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae. Danainae primarily consume plants in the genus Asclepias, more commonly called milkweed. Milkweed contains toxic compounds, cardenolides, which are often consumed and stored by many butterflies. Because of their emetic properties, the plain tiger is unpalatable to most predators. As a result, its colouration is widely mimicked by other species of butterflies. The plain tiger inhabits a wide variety of habitats, although it is less likely to thrive in jungle-like conditions and is most often found in drier, wide-open areas.
D. chrysippus encompasses three main subspecies: D. c. alcippus, D. c. chrysippus, and D. c. orientis. These subspecies are found concentrated in specific regions within the larger range of the entire species.
The plain tiger is believed to be one of the first butterflies depicted in art. A 3,500-year-old ancient Egyptian fresco in Luxor features the oldest known illustration of this species.
D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 cm (2.8–3.1 in). The body is black with white spots. The wings are a brownish orange, the upper side brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots in the centre. The wings are bordered in black and outlined with semicircular white spots. This species exhibits slight sexual dimorphism, as the male has large scent glands on his hindwings, which the female lacks. They appear as a large black spot with a white centre if viewed from the underside
D. chrysippus is a polymorphic species, so the exact colouring and patterning vary within and between populations.
It is similar in appearance to the Indian fritillary (Argynnis hyperbius), which may coexist with it.
The plain tiger is found across the entirety of Africa, where the predominant subspecies is D. c. alcippus. Its range extends across the majority of Asia throughout Indian subcontinent, as well as many south Pacific islands. The plain tiger is even present in parts of Australia. D. c. chrysippus is most common throughout Asia and in some select regions in Africa, while D. c. orientis is present in more tropical African regions as well as some African islands, including Madagascar and the Seychelles.It is also found in Southern Europe and Kuwait. These insects are considered bioinvaders in North America.
14-3-2020 TURTLE BEECH KERALA, INDIA - SACRED LOTUS (Nelumbo nucifera)
Nelumbo nucifera, also known as Padma (Sanskrit: पद्म, romanized: Padma, lit. 'Lotus') or Kamala (Sanskrit: कमल, lit. 'Lotus'), sacred lotus, pink lotus, Indian lotus, or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. It is sometimes colloquially called a water lily, though this more often refers to members of the family Nymphaeaceae. The lotus belongs in the order Proteales.
Lotus plants are adapted to grow in the flood plains of slow-moving rivers and delta areas. Stands of lotus drop hundreds of thousands of seeds every year to the bottom of the pond. While some sprout immediately and most are eaten by wildlife, the remaining seeds can remain dormant for an extensive period of time as the pond silts in and dries out. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. It is cultivated in nutrient-rich, loamy, and often flooded soils, requiring warm temperatures and specific planting depths, with propagation via rhizomes, seeds, or tissue culture, and is harvested by hand or machine for stolons, flowers, seeds, and rhizomes over several months depending on climate and variety.
It is the national flower of India and unofficially of Vietnam.
14-3-2020 TURTLE BEECH KERALA, INDIA - INDIAN POND HERON (Ardeola grayii)
%2020.jpg)
The Indian Pond Heron, known colloquially as the paddybird, is a modestly sized heron with a penchant for concealment. Its plumage is a mélange of streaked olive and brown, which serves as excellent camouflage against the marshy landscapes it frequents. However, when this bird takes flight, it reveals a striking contrast with its bright white wings, a feature that is otherwise hidden when at rest.
This stocky bird possesses a short neck and a robust, thick bill. The back is buff-brown, and during the summer, adults boast elongated neck feathers. When in flight, the Indian Pond Heron is unmistakable due to the white of its wings. It bears a resemblance to the squacco herons but is distinguished by its darker back. Observers should note that individuals may occasionally exhibit red legs during the breeding season, though this is not a common trait.
The Indian Pond Heron is often found stalking prey at the edges of small water bodies or roosting near human habitations. It is adept at utilizing floating vegetation to access deeper waters and is known to frequent marshy wetlands.
14-3-2020 TURTLE BEECH KERALA, INDIA - GREEN MARSH HAWK DRAGONFLY (Orthetrum sabina)
%2020.jpg)
Orthetrum sabina, the slender skimmer or green marsh hawk, is a species of dragonfly in the family Libellulidae. It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia.
%2021.jpg)
14-3-2020 TURTLE BEECH KERALA, INDIA - COMMON BARON BUTTERFLY (Euthalia aconthea)
The Common Baron (Euthalia aconthea) is a medium-sized nymphalid butterfly native to South Asia and Southeast Asia. Famous for its caterpillar’s masterclass in camouflage, this butterfly is a common sight in urban gardens and orchards.
Key Characteristics
Appearance: Sexually dimorphic. Males are dark brown with a subtle metallic sheen and small white spots. Females are paler, larger, and feature more prominent, oblique bands of white patches.
Wingspan: 50–70 mm.
Flight Pattern: Glides frequently, utilizing stiff, rapid wing beats that are rarely flapped below the horizontal plane.
Habitat & Diet
Primary Host Plant: The caterpillar feeds almost exclusively on the leaves of the mango tree (Mangifera indica).
Adult Diet: Unlike many butterflies that only seek nectar, adult Barons are strongly drawn to overripe, rotting fruits on trees or the ground. Fermenting nectar can sometimes put them into a stupor-like state.
Caterpillar CamouflageThe caterpillar is an expert in crypsis. It is bright green with a yellow dorsal stripe and feathery, branched spines.This unique structure mimics the mid-vein and lateral veins of a mango leaf perfectly, rendering the larva virtually invisible to predators.
Geographic RangeIndigenous to the Indian subcontinent (India, Sri Lanka, Nepal) and extends throughout Southeast Asia (Thailand, Malaysia, Philippines) and parts of southern China and Indonesia.
14-3-2020 TURTLE BEECH KERALA, INDIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)
The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists' Union) separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.
It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal.
14-3-2020 TURTLE BEECH KERALA, INDIA - BLUE TIGER BUTTERFLY (Tirumala limniace)
%2020.jpg)
Tirumala limniace, the blue tiger, is a species of butterfly found in South Asia, and Southeast Asia that belongs to the brush-footed butterfly family, Nymphalidae. More specifically it is part of the crows and tigers or danaid group. This butterfly shows gregarious migratory behaviour in southern India. In some places, it may be found in congregations with Danaus genutia, Tirumala septentrionis, Euploea sylvester, Euploea core, Parantica aglea, and at high elevations, with Parantica nilgiriensis, on Crotalaria.
Tirumala limniace is a small butterfly with wide wings. It has a wingspan of 90 to 100 millimeters, with the males being smaller than the females. The upper side of the wing is dark brown to black and patterned with bluish-white, semi-transparent spots and lines. The blue of the bluish-white spots consists of the pigment pterobilin. In general, all butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. Studies on blue tiger butterflies show that high-intensity light significantly increased flight activity. Blue tiger butterflies have a wing surface color that is composed of both light and dark colors. The dark areas on the wing surfaces are the heat absorption areas that allow for the facilitation of autonomous flight.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - WESTERN REEF HERON (Egretta gularis)
The Western Reef Heron, Egretta gularis, also known as the Western Reef Egret, is a medium-sized heron exhibiting remarkable plumage polymorphism. It presents itself in two primary color forms: an all-white morph resembling the Little Egret, and a dark grey morph with a distinctive white throat. During the breeding season, both morphs develop reddish legs and facial skin, and two elongated nape feathers.
To distinguish the Western Reef Heron from similar species, observe the larger, yellower bill and the extended yellow on its thicker legs. The white morph is particularly active when foraging, often employing wing movements or shading techniques. The grey morph's whitish throat sets it apart from other herons within its range. The bill of the subspecies gularis is more pointed, while schistacea has a larger bill, especially towards the base.
This heron favors coastal environments, where it can be seen stalking or ambushing its prey in shallow waters.
The Western Reef Heron is found along the coasts of southern Europe, Africa, and parts of Asia. The subspecies gularis inhabits West Africa to Gabon, with some populations breeding in southern Europe. Subspecies schistacea ranges from the Persian Gulf to the eastern coast of India.
The Western Reef Heron exhibits dynamic foraging behavior, including running through shallow waters, stirring the water with its feet, or using its wings to disturb prey. It is also known to stand motionless, waiting to ambush its next meal.
This species is not particularly vocal, but it does emit a low "kwok" or grating sounds when disturbed or near its nesting site.
Breeding habitats are coastal wetlands. The heron nests in colonies, often on platforms of sticks in trees or shrubs. The usual clutch consists of three to four light blue eggs, with both parents sharing incubation duties.
The Little Egret (Egretta garzetta) is similar in appearance, especially the white morph of the Western Reef Heron. However, the Little Egret has a slimmer bill and lacks the yellow leg extensions seen in the Western Reef Heron.
The diet primarily includes fish, crustaceans, and molluscs. In coastal areas, mudskippers are a regular part of their diet.
The IUCN lists the Western Reef Heron as Least Concern, indicating a stable population without significant immediate threats to its survival.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - LITTLE EGRET (Egretta garzetta)
The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.
Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars.
The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - LITTLE CORMORANT (Microcarbo niger)
The Little Cormorant, Microcarbo niger, is a dainty member of the cormorant family, measuring about 50 centimeters in length. In its breeding attire, it boasts a sleek, all-black plumage adorned with white spots and delicate filoplumes on its face, and a modest crest on the back of its head. The non-breeding or juvenile birds display a more subdued brownish plumage, with a small, distinct white patch on the throat.
Distinguishable from the slightly larger Indian Cormorant by its shorter beak and absence of a peaked head, the Little Cormorant has dark eyes and facial skin. Males and females appear similar, though males are generally larger. A rare silvery-grey plumage has been noted in some individuals.
The Little Cormorant frequents a variety of freshwater bodies, from diminutive village ponds to expansive lakes, and occasionally coastal estuaries.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - INDIAN POND HERON (Ardeola grayii)
%2022.jpg)
The Indian Pond Heron, known colloquially as the paddybird, is a modestly sized heron with a penchant for concealment. Its plumage is a mélange of streaked olive and brown, which serves as excellent camouflage against the marshy landscapes it frequents. However, when this bird takes flight, it reveals a striking contrast with its bright white wings, a feature that is otherwise hidden when at rest.
This stocky bird possesses a short neck and a robust, thick bill. The back is buff-brown, and during the summer, adults boast elongated neck feathers. When in flight, the Indian Pond Heron is unmistakable due to the white of its wings. It bears a resemblance to the squacco herons but is distinguished by its darker back. Observers should note that individuals may occasionally exhibit red legs during the breeding season, though this is not a common trait.
The Indian Pond Heron is often found stalking prey at the edges of small water bodies or roosting near human habitations. It is adept at utilizing floating vegetation to access deeper waters and is known to frequent marshy wetlands.
%2021.jpg)
This heron has its origins in the Old World, with a breeding range that extends from southern Iran across the Indian subcontinent to Burma and Sri Lanka. It is a widespread and common species, yet its cryptic coloration often renders it invisible until it is nearly underfoot.
Typically solitary in its foraging habits, the Indian Pond Heron may gather in numbers during the dry season when prey is concentrated in shrinking wetlands. It is a semi-colonial breeder and has been observed foraging in diverse environments, including garbage heaps and well-watered lawns. The bird's tendency to allow close approaches by humans is notable, and it may form communal roosts in urban areas.
The Indian Pond Heron is generally a silent bird, but it may emit a harsh croak when alarmed or near its nesting sites.
The onset of the monsoons marks the beginning of the breeding season for these herons. They nest in small colonies, often alongside other wading birds, constructing platforms of sticks in trees or shrubs. The nests are typically built at heights of 9 to 10 meters. The male collects materials while the female assembles the nest. Clutches usually consist of three to five eggs, which hatch asynchronously after 18 to 24 days. Both parents are involved in feeding the young, primarily with fish.
%2020.jpg)
The Indian Pond Heron is similar to the squacco heron but can be differentiated by its darker back. To the east of its range, it is replaced by the Chinese Pond Heron.
The diet of the Indian Pond Heron is varied, including crustaceans, aquatic insects, fishes, tadpoles, and occasionally leeches. Outside of wetlands, these herons will also consume terrestrial insects, fish, and amphibians. They have been observed using innovative techniques such as bait-fishing with bread crumbs to attract fish.
The IUCN Red List classifies the Indian Pond Heron as Least Concern, indicating that the species does not currently face a significant risk of extinction.
The Indian Pond Heron's habit of remaining motionless until the last possible moment has given rise to several folk beliefs about its vision. In Sri Lanka, it is referred to as the "half-blind heron," and in Hindustani, the phrase "bagla bhagat" likens the bird to a wolf in sheep's clothing. The bird has also featured in Indian folklore and literature, often noted for its surprising transformation from dull to bright colors upon taking flight.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - BRAHMINY KITE EAGLE (Haliastur indus)
%2019.jpg)
The brahminy kite is distinctive and contrastingly coloured, with chestnut plumage except for the white head and breast and black wing tips. The juveniles are browner, but can be distinguished from both the resident and migratory races of black kites in Asia by the paler appearance, shorter wings, and rounded tail. The pale patch on the underwing carpal region is of a squarish shape and separated from Buteo buzzards. The brahminy kite is about the same size as the black kite (Milvus migrans) and has a typical kite flight, with wings angled, but its tail is rounded unlike the Milvus species, red kite, and black kite, which have forked tails. The two genera are, however, very close.
The call is a mewing keeyew.
%2020.jpg)
This kite is a familiar sight in the skies of Sri Lanka, Nepal, India, Iran, Pakistan, Bangladesh, and southeast Asia and as far south as New South Wales, Australia, through which region it is widespread and resident. They perform seasonal movements associated with rainfall in some parts of their range.
They are mainly seen in the plains, but can sometimes occur above 5000 feet in the Himalayas.
It is evaluated as being of least concern on the IUCN Red List of Threatened Species. However, the species is on the decline in some parts such as Java.
%2022.jpg)
The breeding season in South Asia is from December to April. In southern and eastern Australia, it is August to October, and April to June in the north and west. The nests are constructed of small branches and sticks with a bowl inside and lined with leaves, and are located in various trees, often mangroves. They show considerable site fidelity nesting in the same area year after year. In some rare instances, they have been seen to nest on the ground under trees. A clutch of two dull-white or bluish-white oval eggs measuring 52 x 41 mm is laid. Both parents take part in nest building and feeding, but likely only the female incubates. The incubation period is about 26 to 27 days.
%2023.jpg)
It is primarily a scavenger, feeding mainly on dead fish and crabs, especially in wetlands and marshland, but occasionally hunts live prey such as hares and bats. They may also indulge in kleptoparasitism and attempt to steal prey from other birds.Brahminy kites have even been recorded taking advantage of Irrawaddy dolphins herding fish to the surface, in the Mekong River. A rare instance of a bird feeding on honey at the hive of Apis florea has been recorded. It also eats rice or cooked food left as an offering in India.
14-3-2020 CHANGARAM WETLANDS KERALA, INDIA - BLACK DRONGO (Dicrurus macrocercus)
%2020.jpg)
The black drongo (Dicrurus macrocercus) is a small Asian passerine bird of the drongo family Dicruridae. It is a common resident breeder in much of tropical southern Asia from southwest Iran through Pakistan, India, Bangladesh and Sri Lanka east to southern China and Indonesia and accidental visitor of Japan. It is an all black bird with a distinctive forked tail and measures 28 cm (11 in) in length. It feeds on insects, and is common in open agricultural areas and light forest throughout its range, perching conspicuously on a bare perch or along power or telephone lines.
The species is known for its aggressive behaviour towards much larger birds, such as crows, never hesitating to dive-bomb any bird of prey that invades its territory. This behaviour earns it the informal name of king crow. Smaller birds often nest in the well-guarded vicinity of a nesting black drongo. Previously grouped along with the African fork-tailed drongo (Dicrurus adsimilis), the Asian forms are now treated as a separate species with several distinct populations.
