Paddyfield pipit, Oriental Pipit

Description:

The paddyfield pipit or Oriental pipit (Anthus rufulus) is a small passerine bird in the pipit and wagtail family. It is a resident (non-migratory) breeder in open scrub, grassland and cultivation in southern Asia east to the Philippines. Although among the few breeding pipits in the Asian region, identification becomes difficult in winter when several other species migrate into the region. The taxonomy of the species is complex and has undergone considerable changes. This is a large pipit at 15 cm, but is otherwise an undistinguished looking bird, mainly streaked grey-brown above and pale below with breast streaking. It is long legged with a long tail and a long dark bill. Sexes are similar. Summer and winter plumages are similar. Young birds are more richly coloured below than adults and have the pale edges to the feathers of the upper parts more conspicuous with more prominent spotting on the breast. The population waitei from north-western India and Pakistan is pale while the population malayensis from the Western Ghats is larger, darker and more heavily streaked with the nominate rufulus intermediate.[citation needed] In winter some care must be taken to distinguish this from other pipits that winter in the area, such as Richard's pipit, Anthus richardi and Blyth's pipit, Anthus godlewskii. The paddyfield pipit is smaller and dumpier, has a shorter looking tail and has weaker fluttering flight. The usually uttered characteristic chip-chip-chip call is quite different from usual calls of Richard's pipit (an explosive shreep) and Blyth's pipit (a nasal pschreen). The tawny pipit has less streaking on the mantle and has a black loreal stripe and a longer tail. The Western Ghats population can appear very similar to the Nilgiri pipit

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.
