Brachipteryx Mayor

Identificación

The great shortwing is a stocky bird with short rounded wings, growing to a length of about 17.5 cm (7 in). In general size and shape it resembles a European robin (Erithacus rubecula). The male is almost entirely very dark blue apart from a small patch of white at either side of the base of the tail. The female is a similar blue colour but has a white spot in front of the eye and a reddish-brown rump. It has a reddish-brown sheen to the throat and upper breast, and greyish-blue underparts. Both sexes have red irises, black beaks and greyish legs.

Comportamiento

The great shortwing is a shy and secretive bird which lurks in dense foliage, tangled thickets, vines, deep gullies and streamside vegetation. It can sometimes be heard singing in the early morning from dense cover, often with two birds singing in duet. The song is a high-pitched, wavering series of whistles that increase in pitch and volume, the phrase being repeated, over and over again, for up to a minute. The bird feeds on the ground, foraging through the leaf litter, mosses and lichens, presumably feeding on insects, grubs and other small invertebrates. The nesting habits are unknown, but a juvenile was observed in Lore Lindu National Park in September 2016.
