White-throated Kingfisher, white-breasted kingfisher

Halcyon smyrnensis

Description:

The white-throated kingfisher (Halcyon smyrnensis) also known as the white-breasted kingfisher is a tree kingfisher, widely distributed in Asia from the Sinai east through the Indian subcontinent to the Philippines. This kingfisher is a resident over much of its range, although some populations may make short distance movements. It can often be found well away from water where it feeds on a wide range of prey that includes small reptiles, amphibians, crabs, small rodents and even birds. During the breeding season they call loudly in the mornings from prominent perches including the tops of buildings in urban areas or on wires. This is a large kingfisher, 27–28 cm (10.6–11.0 in) in length. The adult has a bright blue back, wings and tail. Its head, shoulders, flanks and lower belly are chestnut, and the throat and breast are white. The large bill and legs are bright red. The flight of the white-throated kingfisher is rapid and direct, the short rounded wings whirring. In flight, large white patches are visible on the blue and black wings. Sexes are similar, but juveniles are a duller version of the adult. This species forms a superspecies with Halcyon cyanoventris and most major works recognize four geographic races. They vary clinally in size, the shades of blue on the mantle which is more greenish in smyrnensis and fusca and more blue or purplish in saturatior. H. s. gularis of the Philippines has only the neck and throat white. It is sometimes treated as a distinct species, H. gularis. Race fusca is found in Peninsular India and Sri Lanka and is slightly smaller, bluer and with a darker brown underside than the nominate race found in northwestern India. Race saturatior is found in the Andaman Islands and is larger with darker brown underparts. Race perpulchra (not always recognized) is found in northeastern India and is smaller than fusca with paler underparts. Albinism has been noted on occasion. The English of white-throated was introduced since the range is large and geographic adjectives would make the name too restrictive, while the older name of white-breasted would not describe the eastern race which has only the throat white. The call of this kingfisher is a chuckling chake-ake-ake-ake-ake. They are particularly noisy in the breeding season

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.
