Yellow-wattled lapwing

Description:

The yellow-wattled lapwing (Vanellus malabaricus) is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food. These are conspicuous and unmistakable birds found in dry stony and open grassland or scrub habitats. They are medium-sized pale brown waders with a black crown which is separated from the brown on the neck by a narrow white band and large yellow facial wattles. The chin and throat are black and the brown neck and upper breast is separated from the white belly by a narrow blackish line. The tail has a subterminal black band which does not extend into the outer tail-feathers. There is a white wingbar on the inner half of the wing. The bill is yellow at the base. They have tiny yellow carpal spurs. The crown feathers can be raised slightly in displays. They are mostly sedentary but populations make long distance movements in response to the monsoons. They are occasional visitors to the Kathmandu valley in Nepal and a vagrant was seen in Malaysia. There are no recognized subspecies, but there is a size increase from south to north. They are 260-280mm long with a wing of 192-211mm, bill 23-26mm, tarsus 57-66mm and tail 71-84mm. Juveniles have a brown crown and the sexes are alike but males have slightly longer wings and tarsi. The call is a sharp tchee-it call

Habitat:

Udawalawe National Park. The national park was created to provide a sanctuary for wild animals displaced by the construction of the Udawalawe Reservoir on the Walawe River, as well as to protect the catchment of the reservoir. The reserve covers 30,821 hectares (119.00 sq mi) of land area and was established on 30 June 1972. Udawalawe is an important habitat for water birds and Sri Lankan elephants. Udawalawe lies on the boundary of Sri Lanka's wet and dry zones. Plains dominate the topography, though there are also some mountainous areas. The Kalthota Range and Diyawini Falls are in the north of the park and the outcrops of Bambaragala and Reminikotha lie within it. The park has an annual rainfall of 1,500 millimetres (59 in), most of which falls during the months of October to January and March to May. The average annual temperature is about 27–28 °C (81–82 °F), while relative humidity varies from 70% to 83%. Well-drained reddish-brown soil is the predominant soil type, with poorly drained low humic grey soils found in the valley bottoms. Mainly alluvial soils form the beds of water courses. The habitat surrounding at the reservoir includes marshes, the Walawe river and its tributaries, forests and grasslands. Dead trees standing in the reservoir are visual reminders of the extent of forest cover before the construction of the Udawalawe Dam. Areas of open grassland are abundant as a result of former chena farming practices.
