13-3-2020 KERALA, INDIA - BLACK KITE (Milvus migrans)


The black kite was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1770. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Falco migrans in his catalogue of the Planches Enluminées. The type locality is France. The current genus Milvus was erected by the French naturalist Bernard Germain de Lacépède in 1799. Milvus is the Latin word for a red kite; the specific migrans means "migrating" from the Latin migrare "to migrate".


The red kite has been known to hybridize with the black kite (in captivity where both species were kept together, and in the wild on the Cape Verde Islands).

Recent DNA studies suggest that the yellow-billed African races parasitus and aegyptius differ significantly from black kites in the Eurasian clade, and should be considered a separate allopatric species: yellow-billed kite, M. aegyptius. They occur throughout Africa except for the Congo Basin and the Sahara Desert. There have been some suggestions that the black-eared kite (M. m. lineatus) should be elevated to full species status as M. lineatus, but this is not well supported.

Black kites can be distinguished from red kites by the slightly smaller size, less forked tail (visible in flight), and generally dark plumage without any rufous. The sexes are alike though the male is a little smaller and less aggressive (this is the case in most birds of prey). They weigh on average 735 grams. The upper plumage is brown but the head and neck tend to be paler. The patch behind the eye appears darker. The outer flight feathers are black and the feathers have dark cross bars and are mottled at the base. The lower parts of the body are pale brown, becoming lighter towards the chin.


The body feathers have dark shafts giving it a streaked appearance. The cere and gape are yellow, but the bill is black (unlike that of the yellow-billed kite). The legs are yellow and the claws are black. They have a distinctive shrill whistle followed by a rapid whinnying call. Males and females have the same plumage but females are longer than males and have a little larger wingspan. Their wingspan is around 150 cm.

The species is found in Europe, Asia, Africa and Australia. The temperate populations of this kite tend to be migratory while the tropical ones are resident. European and central Asian birds (subspecies M. m. migrans and black-eared kite M. m. lineatus, respectively) are migratory, moving to the tropics in winter, but races in warmer regions such as the Indian M. m. govinda (small Indian/pariah kite), or the Australasian M. m. affinis (fork-tailed kite), are resident. In some areas such as in the United Kingdom, the black kite occurs only as a wanderer on migration. These birds are usually of the nominate race, but in November 2006 a juvenile of the eastern lineatus, not previously recorded in western Europe, was found in Lincolnshire.

14-3-2020 KERALA, INDIA - ORIENTAL RAT SNAKE (Ptyas mucosa)


Ptyas mucosa, commonly known as the Oriental rat snake, or Indian rat snake, is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia. These are large snakes. Typical mature total length is around 1.5 to 1.95 m (4 ft 11 in to 6 ft 5 in) though some exceed 2 m (6 ft 7 in). The record length for this species was 3.7 m (12 ft 2 in), second only to their cousin Ptyas carinata among living colubrid snakes. Despite their large size, oriental ratsnakes are usually quite slender with even a specimen of 2 m (6 ft 7 in) commonly measuring 4 to 6 cm (1.6 to 2.4 in) only around in diameter[which?]. Furthermore, the average weight of ratsnakes caught in Java was around 877 to 940 g (1.933 to 2.072 lb), though larger males of over 2.3 m (7 ft 7 in) (which average mildly larger of the two sexes in the species) may easily weigh over 2.5 kg (5.5 lb). Their color varies from pale browns in dry regions to nearly black in moist forest areas. Rat snakes are diurnal, semi-arboreal, non-venomous, and fast-moving. Rat snakes eat a variety of prey and are frequently found in urban areas where rodents thrive.

Found in Afghanistan, Bangladesh, Myanmar, Cambodia, China (Zhejiang, Hubei, Jiangxi, Fujian, Guangdong, Hainan, Guangxi, Yunnan, Tibet, Hong Kong), Taiwan, India (including Andaman and Nicobar Islands), Sri Lanka, Indonesia (Sumatra, Java, Bali), Iran, Laos, West Malaysia, Nepal, Myanmar, Pakistan (Sindh area), Thailand, Turkmenistan and Vietnam.

12-3-2020 KERALA, INDIA - BLUE TAILED BEE-EATER (Merops philippinus)


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.


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 - TAILED PALMFLY BUTTERFLY (Elymnias caudata)


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 HIBISCUS (Hibiscus syriacus)


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)


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)

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)




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.
