Nesting Habits of the Black Drongo
The bird builds its nest in a fork of a tree, generally 10-30 feet from the ground. The nest of the King-Crow is usually composed of tiny twigs and fine grass-stems, and the roots of khus-khus grass, neatly and tightly woven together, and exteriorly bound round with a good deal of cobweb, in which a few feathers are sometimes entangled; the nest is generally a flimsy concern and the eggs are often visible from below. The cavity is broad and shallow, and at times lined with horsehair or fine grass, but most commonly only with khus. The bottom of the nest is very thin, but the sides or rim rather firm and thick; with cavity around 4 inches in diameter, and about 1½ in depth. This bird lays from between 3-5 eggs varying in size from 0·87 to 1·15 inch, and in breadth from 0·7 to 0·85. With the eggs varying greatly in colour, with some almost a pure white, and others spotted and blotched, especially at the larger end, with claret and light purple on a rich salmon-colored ground
The Black Drongo i.e. King-Crow, so conspicuous on the backs of cattle, telegraph-wires, all through the cold and hot seasons, is conspicuous by its absence during the breeding-season. Many of them retire to woods and gardens to breed, but even when they do not, they keep very quiet while they have their nests and hardly ever show themselves out of the tree.

"Drongos Attack!
You’re invited to join me for a morning jog… Just be prepared for a possible attack from above! Actually, possible attack from above, from below, from the right, from the left, and especially from the rear. It’s a bird; it’s a plane-- No! It’s the Black Drongo! The Black Drongo is a large, loud, black bird that has absolutely no fear of humans. To read more. Go to this link>>>

Indian Treepie
This very pretty bird is a regular visitor to my garden. Bearing in mind its very dashing good looks, I was surprised to learn that it is in fact a member of the Corvidae (crow) family.
This bird is common throughout Tiruvannamalai District and equally happy in open forest, scrub, plantations and gardens
It lives on fruits, invertebrates, small reptiles and the eggs and young of birds; it has also been known to take carrion. It is extremely agile while searching for food, clinging and clambering through branches and will sometimes travel in small mixed hunting parties with unrelated species such as drongos and babblers.
The Indian Treepie has a variety of calls, some loud, harsh and guttural and others pleasing and melodious. One of its commonest calls is kokila and a bob-o-link!

So Many Babblers!
They are many varieties of Babblers to clear up some confusion, I list some differences in two varieties of this bird species.

Salim Ali – Ornithologist
Salim Ali was introduced to the serious study of birds by the Secretary of the Bombay Natural History Society, a Mr. W.S. Millard, which was to fuel Salim's pursuit of a career in ornithology. After a difficult early education at St.Xavier's College, Mumbai, he dropped out and went to Tavoy, Burma, which gave him the opportunity to develop skills as a naturalist and hunter.
In 1917, Salim returned to India, resumed his education, graduating with a Bachelor of Arts degree in Zoology and in the following year married a distant relation. In 1926 he was hired as a guide lecturer at the History Section of the Prince of Wales Museum, Mumbai. In 1930, as the position of guide lecturer has been eliminated due to lack of funds, Salim moved to a coastal village near Mumbai, where he began making observations of the Baya Weaver bird.
Salim Ali was very influential in ensuring the survival of the Bombay Natural History Society, the Bharatpur Bird Sanctuary and the Silent Valley National Park. In 1990, the Salim Ali Centre for Ornithology and Natural History was established at Anaikatty, Coimbatore aided by the Government of India, Ministry of Environment and Forests. Salim also took an interest in bird photograph with a friend Loke Wan Tho.
Ifyou are interested in obtaining what is regarded as the definitive compendium of Indian ornithology, you could do no better than purchasing a copy of Salim Ali, Book of Indian Birds.

Indian Roller
On several occasions I have noticed the Rollers standing guard against predatory Indian squirrels and crows, who have threatened the nest. These birds have a reputation of fearlessness and will dive and roll not only at animal intruders but also at humans.
The Indian Roller is the size of a Pigeon, blue with biggish head, heavy black bill, rufous brown breast, and pale blue abdomen and undertail. But it is dark and pale blue portions of the wings that show up as brilliant bands in flight.
The Roller generally prefers open cultivated country and light forest. From a lookout on a telegraph wire or high spot, it pounces upon some large insect, frog or lizard on the ground, returning with it either to the same perch or flying to another. This bird is regarded as highly beneficial to agriclture as it destroys vast quantities of injurious insects to farmers.

Peacock
The male (peacock) Indian Peafowl has iridescent blue-green or green coloured plumage. The so-called "tail" of the peacock, also termed the "train", is not the tail quill feathers but highly elongated upper tail coverts. The train feathers have a series of eyes that are best seen when the tail is fanned. Peafowl are best known for the male's extravagant tail, which it displays as part of courtship. Peacocks don't develop their long trains until they are 3 years old and they molt the train yearly.
Males possess metatarsal spurs or "thorns" used primarily during fights. Suitable males may gather harems of several females, each of which will lay three to five eggs. Wild peafowl often roost in forest trees and gather in groups called parties. The female (peahen) Indian Peafowl has a mixture of dull green, brown, and grey in her plumage. Although she lacks the long upper tail coverts of the male, she does have a crest. Females can also display their plumage to ward off danger to their young or other female competition. The average lifespan of these birds in the wild is 20 years. The male size: Body, 35 to 50 in (90 to 130 cm); Tail, 5 ft (1.5 m) and Weight: 8.75 to 13 lbs (4 to 6 kg).
Colour in nature occurs due to two basic processes: pigmentation and structural coloring. Pigment is a substance that, like a dye, gives colour to living and inanimate objects. Peacocks and other structurally coloured animals and things, such as rainbows, soap bubbles and the blue sky, instead get most of their colour from light reflection. In peacock feathers, colour is produced by the reflection of light with frequencies within the partial photonic band gap. If you change the view angle, the partial photonic band gap will shift to short wavelengths for oblique incidence.
During mating season the bird will often emit a very loud high pitched cry, "may-awe, may-awe, may-awe." Peafowl are omnivorous and eat plant parts, flower petals, seed heads, insects and other arthropods, reptiles, and amphibians. A peahen's clutch may range from 3—12 eggs, although 4—6 is average. The eggs are usually laid 2 days apart and in the later afternoon. Peafowl eggs take 28 days to hatch. The young are known as peachicks.
Baya Weaver
Walking around the partly dried out Samudram Lake, I spotted 3 Baya Weaver nests high up in an inaccessible thorny bush area. The Baya Weaver has been known to nest in trees with a hornet's nest or with the nests of fiercely biting Red Ants, so this bird is careful about protecting its home. Baya Weavers nest in colonies of up to 20-30, usually in trees near freshwater and open ground and is generally found in grassland, cultivated areas, scrub and secondary growths usually near fresh or brackish water.
Baya Weavers eat mainly grass seeds and have large conical beaks to deal with their food. This bird forages in flocks, in grass as well as on the ground and flock flies in close formation, often performing complicated manouvres.
The Baya Weaver's nest is an architectural feat. It hangs from a palm frond or branch and looks like an upside down flask. The general features are a central nesting area with a long tube that leads to a side entrance. This tube makes it difficult even for snakes to enter the nest. Although they look precarious, most nests are very well attached and are impossible to remove without almost destroying the nest. The nests last well through the 3-month breeding season, sometimes even up to a year. After the breeding season, other small birds may roost in the abandoned nests. The nests are made entirely out of strips of grass which the birds collect by cutting a notch in a tall grass, then stripping off a 30-60cm length.
The birds’ breeding season is December-March. At this time, the males put on a brighter costume and they start to build their amazing nests. No stalks or entire grass blades are used. The birds then use their strong beaks to weave and knot the strips of grass. A newly-made nest is green with fresh grass and turns brown as the grass dries. A bird may make up to 500 trips to complete a nest.
The males are promiscuous and try to attract females by building several nests halfway. These half-built "male" nests look like motorcycle helmets complete with chin strap! A female bird first inspects the male's handiwork of a nest before signalling her approval to him. Once a female chooses to mate with him, he might finish the nest. But often, the female completes the nest.
When the female lays and is preoccupied with incubating the eggs, the male abandons her and immediately uses his other half-finished nests to woo a new female. Most males mate with two females, but sometimes three. The males defend his nests from other males. Meanwhile, the female is left to incubate and raise the brood on her own. 3-4 white eggs are laid and the nestlings are fed insects.

White-breasted Kingfisher
This Kingfisher is a beautiful bird that never fails to get attention. It is a brilliant turquoise-blue with deep chocolate-brown head, neck and underparts, a conscious white ‘shirt front’, and long, heavy, pointed red bill. A white wing-patch prominent in flight. It’s size is that between a Myna and a Pigeon. Both sexes are alike but juveniles are a duller version of the adult.
This is a large Kingfisher, 28 cm in length with a flight both rapid and direct with short rounded wings whirring. This bird has a loud musical frequently repeated chattering song delivered from a tree top or some exposed elevated perch. The call is a chuckling chake-ake-ake-ake-ake. This Kingfisher is noisy and territorial. Nesting season is principally March to July and generally takes place in a horizontal tunnel dug into the side of a dry earth cutting or tunnel. Eggs 4 to 7, white, spherical. Both sexes excavate, incubate and feed the young.

Marshy Land
During the last few weeks we have been experiencing spectacularly great weather, so much so that I have been roused to get up early in the mornings to take my 5 dogs out for a walk and run.

Welcome
Bird Watching
The most important point for bird watching is to remember that although birds constantly move about, their activity is greatest in the early mornings. This is also the time birds are generally more vocal and one can hear their songs.
In wooded areas birds often congregate in large assemblies where they mix in co-operative bands of mixed species, often in regular daily circuit. All the members of the association profits through the co-ordinated efforts of the assembly. While Babblers rummage amongst the fallen leaves for insects, they disturb a moth which is presently swooped upon and captured in mid–air by a Drongo on the look-out. A Woodpecker scuttling up a tree-trunk in search of beetles, stampedes numerous winged insects camouflaged upon the protectively coloured bark or lurking within its crevices, thereby sending out insects for a vigilant Flycatcher.
Banyan and Peepul trees when in ripe fig attract a multitude of birds of many species. A lively scene presents itself as the birds arrive, all eager to gorge themselves on the abundance of fruit around. Some of the best venues for bird watching are afforded by the Silk Cotton, Coral Flower, or Flame-of-the-Forest (Butea) trees in bloom. Almost every small bird of the surrounding countryside flocks to the blossom for the sake of the sugary nectar.
Another popular time to view birds is just after rain when winged termites are emerging from their nests. A termite swarm acts like a magnet upon the bird population. At such times, common birds found at Arunachala are in abundance: such birds; Crows, Kites, Kestrels, Crows, Owls, Mynas, Bulbuls, Sparrows, Bayas, Munias, Treepies, Drongos, Woodpeckers and Barbets.
