Batrachostomus javensis

The Javan frogmouth (Batrachostomus javensis ), sometimes known as Horsfield's frogmouth, is a species of bird in the family Podargidae. It is sometimes considered conspecific with the Blyth's and Palawan frogmouths. Found in Southeast Asia, Indonesia and the Philippines, it lives in subtropical or tropical moist lowland forest.

Appearance

The species grows to a length of about 22 cm (9 in). The upper parts are a mixture of brown, grey, buff and white, spotted with black. The scapulars have several large oval white spots. There is a white stripe above the eye and a white semi-collar. The underparts are brown with buff, cinnamon and white speckling. The flanks and belly are generally paler, with some brown barring. Female birds are rather tawnier and brighter than males, and juveniles are similar to the adults but paler and duller. The beak is brown, the iris yellow and the legs brown.

Habits and Lifestyle

Like other frogmouths, this species is nocturnal and crepuscular. It feeds on such insects as butterflies and moths, ants, grasshoppers, cicadas, beetles, earwigs, cockroaches, caterpillars and small molluscs. Food may be picked up from the ground or gleaned from foliage and branches, or perhaps caught on the wing. It roosts fairly close to the ground, singly or in pairs, crosswise on small branches. It sometimes perches at the top of tall trees during the night.

The nest is built on a low, level branch about 4.5 cm (1.8 in) in diameter and is a very shallow cup made of moss, downy feathers and bark fragments. One or two oval white eggs are laid and are incubated by the parent bird lying along the branch.

Population number

B. javensis is generally considered to be an uncommon bird but it has a very wide range and no particular threats have been recognised, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". It is probably under-recorded in most parts of its range.
