Crimson Breasted Barbet

The Coppersmith BarbetCrimson-breasted Barbet or Coppersmith (Megalaima haemacephala), is a bird with crimson forehead and throat which is best known for its metronomic call that has been likened to a coppersmith striking metal with a hammer. It is a resident found in the Indian Subcontinent and parts of Southeast Asia. Like other barbets, they chisel out a hole inside a tree to build their nest. They are mainly fruit eating but will take sometimes insects, especially winged termites.
.
This species of barbet is found to overlap in range with several larger barbets in most of South Asia. In the Western Ghats, it partly overlaps with the Malabar Barbet which is of a very similar size but having a more rapid call. The red forehead, yellow eye-ring and throat patch with streaked underside and green upperparts, it is fairly distinctive. Juveniles are duller and lack the red patches. The sexes are alike. The Sri Lankan form has more black on the face, more red on the breast and darker streaks on the underside.

During the nesting season, the wear and tear on the feathers can cause the plumage of the upper back to appear bluish.

Throughout their wide range they are found in gardens, groves and sparse woodland. Habitats with trees having dead wood suitable for excavation is said to be important. Birds nest and roost in cavities.

Keeps solitary, pairs, or small groups; larger parties occasionally on abundantly fruiting Ficus trees. Fond of sunning themselves in the morning on bare top branches of tall trees, often flitting about to sit next to each other. The flight is straight, with rapid flaps.

The call is a loud rather metallic tuk…tuk…tuk (or tunk), reminiscent of a copper sheet being beaten, giving the bird its name. Repeated monotonously for long periods, starting with a subdued tuk and building up to an even volume and tempo, the latter varying from 108 to 121 per minute and can continue with as many as 204 notes. They are silent and do not call in winter.

The beak remains shut during each call - a patch of bare skin on both sides of the throat inflates and collapses with each tuk like a rubber bulb and the head is bobbed.

They eat nearly 1.5 to nearly 3 times their body weight in berries each day. Prefers BanyanPeepul, and other wild figs, various drupes and berries, and the occasional insect, caught in aerial sallies.Petals of flowers may also be included in their diet. 

Courtship involves singing, puffing of the throat, bobbing of the head, flicking of the tail, ritual feeding and allopreening.They breed through much of the year with local variation. The breeding season is mainly February to April in India and December to September in Sri Lanka. Both sexes excavate the nest on the underside of a narrow horizontal branch. They may also roost inside the nest holes.Three or four eggs are laid and like in many hole nesting birds the incubation period is not well known but has been estimated to be about 2 weeks. Both sexes incubate. Often two broods are raised in quick succession.

White-browed Fantail/ Fantail Flycatcher

The White-browed Fantail (Rhipidura aureola) is a small passerine bird.
The White-browed Fantail breeds across tropical regions of the Indian Subcontinent and Southeast Asia. The species ranges from Indiaeast to Vietnam, also being seen in Sri LankaMyanmarThailandCambodia and Laos. This Old World flycatcher species is found in forest and other woodland. Three eggs are laid in a small cup nest in a tree.
The adult White-browed Fantail is about 18 cm long. It has dark brown upperparts, with white spots on the wings, and whitish underparts. The fan-shaped tail is edged in white, and the long white supercilia meet on the forehead. The throat and eyemask are blackish and border whitish moustachial stripes.
The White-browed Fantail is insectivorous, and often fans its tail as it moves through the undergrowth.

Whiskered Tern

The Whiskered Tern (Chlidonias hybrida) is a seabird of the tern family Sternidae. This bird has a number of geographical races, differing mainly in size and minor plumage details.
C. h. hybrida breeds in warmer parts of Europe and Asia. The smaller-billed and darker C. h. delalandii is found in east and south Africa, and the paler C. h. javanicus from Java to Australia.
The tropical forms are resident, but European and Asian birds winter south to Africa and the Indian Subcontinent.
This species breeds in colonies on inland marshes, sometimes amongst Black-headed Gulls, which provide some protection. The scientific name arises from the fact that this, the largest marsh tern, show similarities in appearance to both the white Sterna terns and to Black Tern.
The size, black cap, strong bill (29–34 mm in males, 25–27 mm and stubbier in females, with a pronounced gonys) and more positive flight recall Common or Arctic Tern, but the short, forked-looking tail and dark grey breeding plumage above and below are typically marsh tern characteristics. The summer adult has white cheeks and red legs and bill. The crown is flecked with white in the juvenile, and the hindcrown is more uniformly blackish, though in the winter adult this too is flecked with white. The black ear-coverts are joined to the black of the hindcrown, and the space above is mottled with white, causing the black to appear as a C-shaped band. The sides of the neck are white; this sometimes continues across the nape. The collar is less sharply defined. All through the year the rump is pale grey. In the juvenile, the mantle (279 mm) has a variegated pattern. The feathers of the back and scapulars are dark brown, with prominent broad buff edgings and often subterminal buff bars or centers. There is usually an admixture of new gray feathers, especially on the mantle, quite early in the fall. The mantle is silvery-gray in the adult. The call is a characteristickrekk.
In winter, the forehead becomes white and the body plumage a much paler grey. Juvenile Whiskered Terns have a ginger scaly back, and otherwise look much like winter adults. The first winter plumage is intermediate between juvenile and adult winter, with patchy ginger on the back.
The Whiskered tern eats small fish, amphibians, insects and crustaceans.
