List of birds of Tamil Nadu
These birds are adapted to an aquatic existence with webbed feet, flattened bills, and feathers that are excellent at shedding water due to an oily coating.
Order: Otidiformes Family: Otididae Bustards are large terrestrial birds mainly associated with dry open country and steppes in the Old World.
Order: Pterocliformes Family: Pteroclidae Sandgrouse have small, pigeon like heads and necks, but sturdy compact bodies.
Order: Phoenicopteriformes Family: Phoenicopteridae Flamingos are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) tall, found in both the Western and Eastern Hemispheres.
Their oddly shaped beaks are specially adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down.
Order: Charadriiformes Family: Turnicidae The buttonquail are small, drab, running birds which resemble the true quails.

Order: Charadriiformes Family: Rostratulidae Painted-snipes are short-legged, long-billed birds similar in shape to the true snipes, but more brightly coloured.
They are identifiable by their huge feet and claws which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat.
Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.

Order: Ciconiiformes Family: Ciconiidae Storks are large, long-legged, long-necked, wading birds with long, stout bills.

Order: Strigiformes Family: Strigidae The typical owls are small to large solitary nocturnal birds of prey.
Found in tropical woodlands worldwide, they feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits.
