Invertebrates Flora Botanical gardens Civil societies Sri Lanka is a tropical island situated close to the southern tip of India.
In addition to the many resident birds, a considerable number of migratory species winter in the country to escape their northern breeding grounds.
The wet zone, with two monsoons, is in the south western quarter of the island, where the few remaining rain forests are found and humidity is high.
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: 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.
They have lobed toes and are excellent swimmers and divers; however, their feet are placed far back on their bodies, making them quite ungainly on land.
Order: Charadriiformes Family: Haematopodidae The oystercatchers are large and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.
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.
Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head.
Order: Phaethontiformes Family: Phaethontidae Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers.
Order: Procellariiformes Family: Oceanitidae Southern storm-petrels are small birds which spend most of their lives at sea, coming ashore only to breed.
Order: Procellariiformes Family: Hydrobatidae Northern storm-petrels are small birds which spend most of their lives at sea, coming ashore only to breed.
Order: Procellariiformes Family: Procellariidae The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium septum and a long outer functional primary.
Order: Ciconiiformes Family: Ciconiidae Storks are large, long-legged, long-necked, wading birds with long, stout bills.
Order: Suliformes Family: Anhingidae Anhingas or darters are often called "snake-birds" because they have long thin necks, which gives a snake-like appearance when they swim with their bodies submerged.
Found in tropical woodlands worldwide, they feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits.
Order: Bucerotiformes Family: Upupidae Hoopoes have black, white and orangey-pink colouring with a large erectile crest on their head.
Order: Bucerotiformes Family: Bucerotidae Hornbills are a group of birds whose bill is shaped like a cow's horn, but without a twist, sometimes with a casque on the upper mandible.
Order: Coraciiformes Family: Alcedinidae Kingfishers are medium-sized birds with large heads, long, pointed bills, short legs and stubby tails.
Order: Coraciiformes Family: Coraciidae Rollers resemble crows in size and build, but are more closely related to the kingfishers and bee-eaters.
Order: Piciformes Family: Picidae Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails and long tongues used for capturing insects.
Order: Passeriformes Family: Pittidae Pittas are medium-sized by passerine standards and are stocky, with fairly long, strong legs, short tails and stout bills.
Some are colourful with yellow, red or orange vents, cheeks, throats or supercilia, but most are drab, with uniform olive-brown to black plumage.
They mainly occur as breeding species, as the common name implies, in Europe, Asia and, to a lesser extent, Africa.
Order: Passeriformes Family: Zosteropidae The white-eyes are small and mostly undistinguished, their plumage above being generally some dull colour like greenish-olive, but some species have a white or bright yellow throat, breast or lower parts, and several have buff flanks.
Order: Passeriformes Family: Timaliidae The babblers, or timaliids, are somewhat diverse in size and colouration, but are characterised by soft fluffy plumage.
• Acridotheres tristis melanosternus Order: Passeriformes Family: Turdidae The thrushes are a group of passerine birds that occur mainly in the Old World.
