Black Kite (Milvus Migrans) — Kalu Parandu in Tamil.


I have previously made two postings on Arunachala Birds about the Black Kite, you can view them at this link here and here.

For a number of months this year a colony of around 15 Kites regularly gathered at the Samudram Eri. Because of heavy undergrowth and a number of ponds on the 700 acre Eri, food was plentiful for their community.
 
Small Cluster of 3 Kites on Samudram Eri


My dogs and I walk daily on the Samudram Eri and as some of the ponds dried out, large dead fish were often to be seen on the top of the water and available to the animals frequenting the water-holes.


Max to the rescue

Some of the dead fish were heavy and to help out my Labrador Retriever Max who would jump into the pond, gather the dead fish in his mouth, swim to the side and then deposit the dead fish on the pond’s bank.

In this way the colony of Kites became quite familiar with me and my dog gang and would often hang around for a nice fish dinner. The Kites were so comfortable with our presence that on one occasion when I was holding a dead fish by its tail and looking for a high spot to deposit it for the birds, they clustered over me, flying barely 20 feet from my head, eager to be the sole recipient of the large dead fish. The Kites were respectful of both my space and my 6 dogs and in no way threatened or bullied us. It was a truly a “Disney” moment.

However I am familiar of how opportunistic Black Kites can be, as one day swimming in what was then a Lake, a large Black Kite came swooping down and plucked a nearby duckling (who was swimming with its family) from the water and quickly made off with it.


Description of Black Kite 

This bird is around 24 inches, approximately the size of a Vulture. The Black Kite has dark brown plumage with a paler head and neck and with a dark patch behind the eyes. The outer flight feathers are black and feathers have dark cross bars and are mottled at the base. The cere, gape and legs are yellow. The Black Kite has a distinctive shrill whistling sound followed by a rapid whinnying call — ewe-wir-wir-wir — both uttered whilst on a perch and also on the wing. 

Black Kite

The Black Kite inhabits a wide variety of habitats such as semi-deserts, grasslands and woodlands but avoids dense forests. 


Kalu Parandu in Tamil


It is generally found near human habitations whether city or hamlet. Skilful when flying, turning and twisting to scoop scraps from traffic congested thoroughfares and avoiding tangles of overhead telephone and electric wires. The Indian Black Kite population is well adapted to living in cities and found in densely populated areas. Large numbers may be seen soaring in thermals over cities. In some places, they will readily swoop and snatch food held by humans. The bird which is both resident and migratory remains permanently in tropical regions. 



Black Kite in Flight




Sexes are alike and they singly or gregariously scavenge in towns and villages. Black Kites are opportunistic hunters and are more likely to scavenge. They are attracted to smoke and fires, where they seek escaping prey. This behaviour has led to the belief that Kites spread fires by picking up burning twigs and dropping them on dry grass. They spend a lot of time soaring and gliding in thermals in search of food. The Black Kites' food consists of carrion, garbage, earthworms, winged termites, reptiles, rodents, fish, bats and young birds. 

The breeding season of the Black Kite in India is during winter. At that time the bird forms large communal roosts. Flocks may fly about before settling at the roost. 

The bird’s nest which is an untidy platform of twigs, iron wire, tow, rags and is built in a large tree, roof or the cornice of a building, Both sexes take part in nest building, incubation and care of chicks. 


Black Kite' Eggs


The clutch usually contains 2 or 4 eggs, pinkish white, light spotted and blotched with reddish brown.The incubation period varies from 30–34 days. Chicks of the Indian population stay at the nest for nearly two months. Birds are able to breed after their second year.

Black-winged Stilt: Pavilla Kallan (Tamil)



First identified the Black-winged Stilt last season on the Samudram Eri here in Tiruvannamalai and was able to take several photos of the Stilt wading in the waters, but as my camera is not fit for purpose, am illustrating the below narrative of this bird with photographs taken from the web. 


Black-winged Stilt Juvenile


The Black-winged Stilt in India is both local and migratory. Here at Tiruvannamalai I have only spotted it during the wet season, but in South India its more of a permanent fixture at cooler places such as Karnataka. 


Juvenile in Flight

The Black-winged Stilt’s name in Tamil is Pavilla Kallan and has the scientific name of Himantopus Himantopus. Himantopus comes from Greek meaning “strap foot” or “thong foot”. The long, distinctive legs of the black-winged stilt account for nearly 60 percent of its height. 


Black Winged Stilt Grooming

This bird is about 10 inches long and is a large black and white wader with long orange-red legs and a straight black bill. It has black on the back of the neck, a white collar and a red iris. Both sexes are similar, and the plumage does not change during the year. 

Black-winged Stilts give a repeated high-pitched barking call. Immature Stilts lack black on the back of the neck and have grey-brown wings and their back is speckled with white. They have a smudged grey crown, which extends down the back of the neck as the birds get older. The lifespan of the Black-winged Stilt is about 20 years. 


Stilt with Fish

This bird pairs or flocks in social groups at marshes, jheels, village tanks, salt pans and tidal mudflats. Its stilt legs enable it to wade into comparatively deep water where it probes in the squelchy bottom mud for worms, mollusces and aquatic insects etc. When probing for food its head and neck are submerged at a steep angle with the back part of its body sticking out. 


Stilt Bathing

Black-winged Stilts, like many shorebirds, don't swim while feeding. They feed by pecking at food items while wading in the water. 


Adult Stilt in Flight

However it is in fact a very good swimmer but weak in the air. When flying it flaps its wings with its neck extended and its long red legs trailing beyond the tail.

Black Winged Stilt Coming in to Land

The Black-winged Stilt is a social species, and is usually found in small groups. The call it makes is a squeaky, piping chek-chek-chek.

The nesting season of the Black-Winged Stilt is principally April to August. It generally nests in small colonies, within which, mated pairs strongly defend their individual territories. 


Eggs in Nest

It makes its nest in a depression on the ground on the edge of a jheel or marsh, or on a raised platform of pebbles in shallow water, lined with vegetable scum or flags of reeds. 


Chick already emerged from egg


It often breeds in large colonies and lays around 3 to 4 eggs, light drab in colour, densely blotched with black, which closely resemble the eggs of Red Wattled Lapwing.

Both sexes incubate the eggs and look after the young. The incubation period of the eggs is around 25 days.

Variety of Migratory Waterbirds at Keelnathur Lake


It was reported this week in Nationally syndicated newspapers that a huge flock of Pelicans have been spotted at Keelnathur Lake, an irrigation tank, situated along the Tindivanam Road approximately 30 kms from Tiruvannamalai. Naturists claim that this is the first time Pelicans have been spotted so near Tiruvannamalai and that too in huge numbers. 


Pelicans and Painted Storks, Keelnathur Lake nr. Tiruvannamalai

The Pelican (Koohai Kada) is categorised into four species, with the one spotted at Keelnathur Lake being the Spot Billed Pelican.


Spot Billed Pelican

As well as Pelicans, also a large number of Painted Storks (Manjal Mooku Narai) and Purple Swamphens (Neela Thazhai Kozhi) are also at the Lake. Naturists have stated that “Spotting so many birds including such rare varieties signify the lake’s potential as a bird sanctuary.” 

The lake’s uncontaminated water, good fish population, marshy nature, the presence of bushes and vines and grass cultivation in nearby fields make it a haven for the birds. 


Painted Storks

Other Bird followers state, “We are surprised to spot the Pelican in such huge numbers near Tiruvannamalai. I have never spotted them anywhere near this hilly region. They might be in the lake for a long time. Now only we spotted them and realised the importance of Keelnathur Lake as a marshy wetland, a rare phenomenon in Tiruvannamalai. Even people living nearby don’t seem to be hunting or disturbing them. That’s why they thrive here. The place need to be preserved as such.” 


Purple Swamphen

Heavy rains are expected in the upcoming monsoon season, which bodes well for a large and varied migratory bird population this Winter at our own Samudra Eri at Tiruvannamalai.

Rosy Starling


A report (repeated below) appeared in a National newspaper this week about the sighting of Rosy Starlings in the Tiruvannamalai area. 

“A flock of rosy starlings, a bird resembling a mynah but which has a distinct colour pattern, has been spotted in Tiruvannamalai. It is being claimed that it is the first time the bird is spotted here. Painter and bird watcher Kumar alias Sivakumar spotted the bird in Samudram Eri during his regular bird watching a few days ago. “The birds with light pink pattern in its body came in large numbers like a cloud. They landed in the lake area. This is the first time I am observing them here,” he said. 


Rosy Starlings on the Samudram Eri

V. Arun, a bio diversity activist and expert, associated with Forest Way, an organisation that has been taking up successful afforestation project in the Tiruvannamalai hills, said that he has spotted rosy starlings in Mumbai and other northern part of the nation. 

“They are migratory birds not frequently seen in South India. I have never seen them in Tiruvannamalai and never heard someone else spotting the bird here. Kumar’s spotting the bird is the first time probably,” he said. 

“Ecology in Tiruvannamalai hill and surrounding areas is improving and we spot two-three new species every year here”. When asked how the bird was seen even after the winter is over, he said some migratory birds were seen for a few days in a spot while taking upward journey and they would be seen again for a few days in the same spot during their return journey. Kumar might have seen them on their return journey, he said.” 

Below is information about the Rosy Starling, a new arrival to us at Tiruvannamalai. 


Rosy Starling 


Sturnus Roseus. Summer Plummage: Adult Male (Centre), Female (Below), Juvenile (Behind)

The Rosy Starling (Pastor Roseus) is a Passerine Bird in the Starling family and is also known as the Rose-Coloured Starling or Rose-Coloured Pastor. In Tamil this bird is known as Cholam Kuruvi. It is the size of a Mynah bird. Rose pink colour with glistening black head, neck and upper breast, wings and tail, and pale orange legs and bill. Males in the breeding season have a long, recumbent, pointed crest on the crown and nape which sometimes is more fluffed and prominent. 


Duller and Browner Adults


Females have a short crest and are duller overall, especially without the sharp separation between pink and black. Young birds and adults in winter plumage (non breeding) are duller and browner

Rosy Starling Eating Grain

 
Its keeps near cultivation, particularly Jowari (Sorghum) and ripening grain crops. 


Starling at Indian Coral Tree

This bird is attracted to flowering trees and nectar of Simal Flowers (Salmalia). It likes Banyan and Peepul figs, Lantana, Peeloo (Salvadora) and other berries. The Rosy Starling cross pollinates these types of trees. Its diet is chiefly fruits, berries, flower-nectar, cereal grains and insects. 

Males have a chattering, warbling song of harsh as well as pleasant notes uttered chiefly when satiated and resting in a shady tree during the mid-day heat. As well as its mixture of squeaks and rattles it also exhibits much wing trembling.

The Rosy Starling is a colonial breeder, and like other Starlings, is highly gregarious, forming large winter flocks. It breeds in Eastern Europe and Western and Central Asia on stony hillsides in May and June. The breeding grounds overlaps that of migratory locust and grasshoppers thus providing the staple food of this bird and its young from the time the latter hatch. In years when Grasshoppers and other insects are abundant, it will erupt well beyond its core range.

The Rosy Starling is one of the earliest winter visitors. It begins arriving July-August and departs mid-April. It is often in small clouds of up to 500 birds or more. The bird can be found in winter throughout India. Its abundant in N.W. India and the Deccan and diminishes in number going southwards.

Nature Adapts


I posted a narrative on Arunachala Grace at this link here about the water problem at Samudram Eri (a reservoir south of Arunachala). The 750 area used to a haven for a multitude of bird species but now due to deforestation and the subsequent on-going industrial scale sand quarrying (with heavy machinery), much of the joy of the area has been destroyed for our sweet feathered friends.



Thorny bush branches covered by creepers


But its interesting to note how quickly nature is able to adapt to new circumstances. Previously the area was heavily covered with Acaia Arabica Nilotica (what I euphemistically call "thorny bush"). The trees were cut down and transported out by lorry, leaving just residual thorny branches on the ground. Subsequently creepers are now intertwining with the branches, and with great serendipity have become a haven for many species of birds such as Swift, Coucal, Drongos and Francolins. It really is a case of every cloud has a silver lining!

Southern Grey Shrike


Shrikes are passerine birds of the family Laniidae. The family name, and that of the largest genus, Lanius, is derived from the Latin word for "butcher" because of their feeding habits. Among its super family, the closest relatives of the Laniidae are the Corvidae (crows and allies). 


Adult male


The Southern Grey Shrike, Lanius Meridionalis, is a member of the Shrike family. It is closely related to the Great Grey Shrike, Lanius Excubitor, but the species do not interbreed and are separated by choice of habitat. This bird is not a common resident in Tamil Nadu, but I have viewed it several times in the open scrub country (which it prefers to habituate) of the Samudram Eri. 



Bird Preening


The Southern Grey has a narrow black forehead and broad face mask, grey mantle with white scapulars, broad white tips to secondaries, white sides tip to tail, and white underparts. Juveniles have sandy cast to grey upperparts, buff tips to tertials and coverts, and grey mask. 



Bird in Flight from Above


This bird eats small vertebrates and insects. Most important among invertebrate prey are insects, especially beetles, crickets, grasshoppers and bumblebees. To hunt it perches on an elevated spot in a conspicuous upright stance some distance above ground not only to watch for prey but also to advertise its presence to rivals. Alternatively this bird may scan land below during flight, staying in one place during prolonged bouts of hovering that may last up to twenty minutes. 


Bird in flight from below


This Shrike is medium-sized with a hooked beak reminiscent of a bird of prey. It has a harsh strident call. Prey is killed by hitting it with its beak, aiming for the skull in vertebrates. If too large to swallow in one or a few chunks, it is transported to a feeding site by carrying it in the beak or (if too large) in the feet. 

 
Adult Bird with impaled food in its "larder"

It is then impaled upon a sharp point such as thorns or barbed wire or even just wedged between forking branches. These “larders” are typically around a metre above ground and although they can be found anywhere within the birds' territory generally tend to be in the general vicinity of the bird’s nest sites. 


Eggs of the Southern Grey Shrike


Shrikes are territorial and are generally monogamous. Males attract females to their territory with well stocked caches, which may include inedible but brightly coloured items. During courtship the male will perform a ritualised dance which includes actions that mimic the skewering of prey on thorns and will feed the female. To lay its eggs, Shrikes make simple, cup-shaped nests from twigs and grasses, in bushes and the lower branches of trees.

Sirkeer Malkoha



Over the last few weeks have been noticing a Sirkeer Malkoha near my house. Think its probably the same bird, because its usually close or around the same spot. This is a largish bird that is mainly brown and rufous in colour, It has a long heavy tail edged with white tipped graduated tail feathers. It is related to the Coucal (which is commonly observed throughout this area). The bill of the Sirkeer Malkoha is hooked and bright cherry-red and yellow. The sexes are the same but juveniles are duller. 


Bird Preening


The Samudram Eri seems to be the perfect location for this bird because its preference is open scrub and thorn jungle, singly or in pairs. It moves about thickets and undergrowth like the Crow-Pheasant, searching for food such as insects, lizards, fallen fruit and berries. This bird is a feeble flier, and is similar in movement to the Coucal in that it ascends trees rapidly and agilely hops from branch to branch. 


Close up of its Cherry Red and Yellow Beak


The call of the bird is a subdued "bzuk... bzuk" ; also an alarm call of "p'tang" with a metallic quality. It has a sharp kek-kek-kek-kerek-kerek of the quality of the Rose Ringed Parakeet’s shrieks.

Adult Bird on Tree


Its nesting season is from March to August, varying with locallity. It is non parasitic. Its nest is usually a shallow saucer of twigs lined with leaves in a thorn bush or sapling about 2-7 metres up. It lays from 2-3 white eggs.
