Winter Plumage of Black-headed gull

Identification tip: It is a small gull. In flight, the white leading edge to the wing is a good field mark. The summer adult has a chocolate-brown head, pale grey body, black tips to the primary wing feathers, and red bill and legs. The hood is lost in winter, leaving just 2 dark spots.

The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal relish. It is a noisy species, especially in colonies. It is not seen at sea far from coasts

Identification tip: It is a long-billed nectar-feeding bird. Unlike typical sunbirds, males and females are very similar in plumage

Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests. It is usually found below the canopy. They are also found in gardens, attracted especially by flowers that yield nectar

In southern India it breeds from December to August. Two eggs are the usual clutch. The nest is a compact cup attached under a leaf of banana or similar broad leaved plant. The nest is suspended from the underside of the leaf using 150 or so "pop-rivets" of cobwebs and vegetable fibre, a unique method of using spider silk for animal architecture

The red junglefowl was first domesticated at least five thousand years ago in Asia, since then it has spread around the world, and the domestic form is kept globally as a very productive food source of both meat and eggs.

Identification tip: 
Male and female birds show very strong sexual dimorphism. Males are much larger; they have large red fleshy wattles and comb on the head. The tail is composed of long, arching feathers that initially look black but shimmer with blue, purple and green in good light. The female has no fleshy wattles or comb on the head.

They are omnivorous and feed on insects, seeds and fruits including those that are cultivated such as those of the oil palm. Red junglefowl regularly bathe in dust to keep just the right balance in their plumage.The dust absorbs extra oil and subsequently falls off

The Indian cormorant or Indian shag

Identification tip: 
It is a gregarious species that can be easily distinguished from the similar sized little cormorant by its blue eye, small head with a sloping forehead and a long narrow bill ending in a hooked tip.

This cormorant fishes gregariously in inland rivers or large wetlands of peninsular India and northern part of Sri Lanka. The Indian cormorant makes short dives to capture fish and a group will often fish communally, forming a broad front to drive fish into a corner

Identification tip: The Indian robin is sexually dimorphic in plumage with the male being mainly black with a white shoulder patch or stripe whose visible extent can vary with posture. Their long tails are held erect and their chestnut undertail covert and dark body make them easily distinguishable from the pied bushchat and the oriental magpie robin.

Behavior: It is widespread in the Indian subcontinent. They are commonly found in open scrub areas and often seen running along the ground or perching on low thorny shrubs and rocks.
All populations are resident and non-migratory. It can come close to human habitation and can be seen frequently perch on rooftops.

They feed mostly on insects but are known to take frogs and lizards especially when feeding young at the nest. Nests are generally built between rocks, in holes in walls or in a tree hollow

It is gregarious and a very social bird. It forage in small groups of seven to ten birds, a habit that has given them the popular name of Seven Sisters. They feed mainly on insects, but also eats grains, nectar and berries. When foraging, some birds take up a high vantage point and act as sentinels. They are known to gather and mob potential predators such as snakes

Identification tip:  The sexes are identical, drably colored in brownish grey with a yellow-bill

Read more at Wikipedia

Identification tip: Dark crown, nape, eyestripe. Blue speculum with white borders; orange legs and feet. The male has a red spot on the base of the bill. They are almost identical to Indian spot-billed duck just that the speculum is Blue instead of Green as in Indian spot-bill
Female Koel
Koel - Male

Koel - Female In flight

Identification tip: The male of the nominate race is glossy bluish-black, with a pale greenish grey bill, the iris is crimson, and it has grey legs and feet. The female of the nominate race is brownish on the crown and has rufous streaks on the head. The back, rump and wing coverts are dark brown with white and buff spots. The underparts are whitish, but is heavily striped

They are very vocal during the breeding season (March to August in the Indian Subcontinent), with a range of different calls. The familiar song of the male is a repeated koo-Ooo

Behavior: The Asian koel is a brood parasite, and lays its single egg in the nests of a variety of birds - long-tailed shrike, common myna, and most commonly - jungle crow and house crow. Sometimes it has been found to parasitize the black drongo and black-hooded oriole as well. The koel is not known to lay eggs in an empty host nest. A female may remove a host egg before laying. Eggs hatch in 12 to 14 days. The young koel does not always push out eggs or evict the host chicks, and initially calls like a crow. The young usually fledge in about a months time

Lesser golden-backed woodpecker or Lesser goldenback - also known as Black-rumped flameback woodpecker

Identification tip: The black throat finely marked with white immediately separates it from other golden backed woodpeckers in the Indian region. The head is whitish with a black nape and throat. Unlike the greater flameback it has no dark moustachial stripes

The adult male has a red crown and crest. Females have a black forecrown spotted with white, with red only on the rear crest. Young birds are like the female, but duller

Like other woodpeckers, this species has a straight pointed bill, a stiff tail to provide support against tree trunks. Two toes pointing forward, and two backward. The long tongue can be darted forward to capture insects

Indian Silverbill or White-throated munia

Identification tip: It has a conical silver-grey bill, buff-brown upper parts, white underparts, buffy flanks and dark wings. The tail is black and the wings are dark contrasting with a white rump

It feeds mainly on seeds, but also takes insects and has been known to visit nectar bearing flowers. It frequents dry open scrub, fallow land and cultivation, sometimes near water

Identification tip: It is grey backed with white undersides. It has grey-back, black hood, white cheek patch and a white wing-bar. The underparts are white with the black central stripe running along the length. The great tit in the new sense is distinguishable by the greenish-back and yellowish underside

They sometimes use their feet to hold insects which are then torn with their beak. They may also wedge hard seeds in a bark crevice before hammering them with their beak

The nests are placed in hollows in trees or in a wall or mud-bank with a narrow entrance hole and the floor of the cavity is lined with moss, hair and feathers. They sometimes make use of the old nest of a woodpecker or barbet

The Spot-Billed Duck  is known by many names including the Yellow-Nib, Indian Spot-Billed, Spotbill  as well as being locally known as Garm Pai or Gugral. Its name comes from the red spots at the base of their yellow-tipped black bills, which the females of the species lack.

Spot-bills are native to Asia, being found largely in Haryana, India, but also in China, Japan and the USSR. They live in freshwater lakes, ponds, rivers and marshes and are normally found in waters with a depth of 0-1,867 meters or 0-6,125 feet.

They nest on dry ground on top of piles of thick moss, grass, feathers and/or down. Relationships in this species are monogamous and females will lay 7-10 white colored eggs that she incubates for 26-30 days. These ducks are known to hybridize (mate with other similar species of duck) naturally with mallards and in captivity, with the Pacific Black Duck and the Philippine Duck. Breeding season differs between north and south India and with water levels: i.e. from July to October in Northern India and November to December in Southern India.

Identification tip: This duck is around the same size as a mallard and has a scaly patterned body with a green speculum and a band of white tertials that is prominent in flight

The eastern spot-billed duck is darker and browner; its body plumage is more similar to the Pacific black duck. It lacks the red bill spot, and has a blue speculum

The ashy prinia or ashy wren-warbler is a small warbler. This prinia is a resident breeder in the Indian Subcontinent, ranging across most of India, Nepal, Bangladesh, Bhutan, Sri Lanka and western Myanmar. It is a common bird in urban gardens and farmland in many parts of India and its small size, distinctive colours and upright tail make it easy to identify. The northern populations have a rufous rump and back and have a distinct breeding and non-breeding plumage while other populations lack such variation.

Also known as Brainfever bird. The resemblance to hawks gives this group the generic name of hawk-cuckoo and like many other cuckoos these are brood parasites, laying their eggs in nests of babblers. Read more here

Identification tip: They can be confused with the large hawk-cuckoo, which, however, has dark streaks on the throat and breast.

Identification tip: The crown and nape are grey, with a typical shrike black bandit mask through the eye. There is a small white wing patch (its visible in the photo above, observe closely), and the bill and legs are dark grey

The bay-backed shrike inhabits dry, bushy areas with scattered trees or at the edge of woodland

Here is a Youtube video showing the bird in action

Flock of Northern Shoveler

Identification tip: It has a large broad, rounded bill. Dark green head, white neck and rufus belly 

This is a bird of open wetlands and a winter visitor to Indian subcontinent. It feeds by dabbling for plant food, often by swinging its bill from side to side and using the bill to strain food from the water. Their wide-flat bill is equipped with well-developed lamellae – small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. 
This adaptation, more specialized in shovelers, gives them an advantage over other puddle ducks, with which they do not have to compete for food resources during most of the year. Thus, mud-bottomed marshes rich in invertebrate life are their habitat of choices

Black-winged kite - also commonly known as Black-shouldered kite though Black-shouldered kite is the name of similar species found in Australia

Identification tip: This kite is distinctive, with long-wings, white, grey and black plumage and owl like forward-facing eyes with red irises

 The way it hovers the grasslands, it appears as it got stuck in the air. Even after fast flapping of wings, the kite doesn't move an inch. Once it sets the eye on the target, it then dives and rise up with the catch. Here is a beautifully captured video of it hovering the plans

The Wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily.

Also known as Cotton teal

Identification tip: The male has a white head, neck and underparts with a glossy green back that appears black in dull light. In breeding season, the male has a black band around the base of the neck. The female is predominately brown with darker plumage on the wings.

The species tends to avoid running water where deep-water vegetation cannot grow. The species requires dead trees with hollows near water for nesting and roosting sites. Individuals flatten their head and neck on the water surface and rapidly filter water through their bill while swimming fast, swallowing food with an upward jerk of the head (Check the female doing the same in the pic). Aquatic insects are also eaten. The species is likely to be monogamous

Also know as common crow. There are several less known facts about crows. One is that crows are masters at stashing food in many caches, moving it sometimes two or three times, and remembering exactly where they placed it. In fact, for their size, crows have the largest brains of all birds except some parrots. Their brain-to-body ratio is equivalent to that of a chimpanzee and amazingly, not far off that of a human.
