Thick-billed Warbler

The Thick -billed Warbler ( Phragamaticola aedon, Syn Acrocephalus aedon ) is a species of bird in the family of warbler -like. The species inhabits young forest stages in southern Siberia and winters in India. In Central Europe the species is an extremely rare exception in the fall.

Features

The large -billed reed warbler counts with a body length from 16.0 to 17.5 cm to the great reed warblers. The size is about the great reed warbler. The beak is short and strong, the primaries projection is compared to other members of the genus and the short tail is strongly rounded at the end.

Much like the garden warbler type shows no distinctive coloring or drawing features. The top is gray-brown; Rump, tail base and apex are reddish brown slightly warmer. The underside is dirty white; Breast, flanks and under tail-coverts are tinged beige. The head, in contrast to all other occurring in Europe warblers no significant over- eye-streak. The reins Streif is light gray, the eye-ring whitish beige gray, so that the eye optically clearly stands out. The darker apex often forms an indicated head cap. The upper mandible is dark gray, the lower mandible pale orange - beige. The legs are dark gray.

Vocalizations

The continuous singing resembles that of marsh warbler and Yellow Warbler. He is loud, is often put forward at a rapid pace and consists of numerous imitations of the song of other birds combined with rough chirping sounds. Many verses are repeated several times. Overall, the song is not quite as fast as that of the marsh warbler and it lacks the " zi - uh " elements of the Yellow Warbler singing. At the hatchery, various full of clicks shouts of " tschack " or " tjack " heard.

Distribution, habitat and hikes

The distribution area of the thick -billed warbler is limited to the south of Siberia. He settled there tight Vorwaldstadien from birch and willow at the edge of the taiga bogs, on forest clearings and on older clearcuts. The species overwinters in India.

Inventory and risk

There are no estimates of the size of the world population. The species is IUCN frequently, at least in parts of its range and is therefore considered safely.
