Eastern Bonelli's Warbler
The Balkan Warbler (Phylloscopus orientalis ) is a passerine bird in the genus of warblers (Phylloscopus ) and the family of the warbler -like ( Sylviidae ). We distinguish between no subspecies. It forms together with the mountain warbler a super species. As rare Irrgast the Balkan Warbler is occasionally observed in Central Europe.
Description
The Balkan Warbler was once seen as a subspecies of the eastern mountain warbler. In the light of recent research results ( Sangster et al. 2002, Parkin 2003), he is now commonly regarded as a separate species. He is about 11 to 12 cm long - a total of something larger than the mountain warbler. Its top is like the mountain warbler gray-brown, but this comparatively slightly more brownish tint while under wing-coverts and axillaries have a paler yellow. Males and females have the same coloring.
The reputation of the Balkan warbler is monosyllabic and harder in comparison to the mountain warbler: " Tschip " (similar to a young house sparrow ), or even a wooden " tut ", the train also a quieter " iss ". The song is faster than that of mountain warbler, reminiscent of the trill in the blue tit song.
Habitat and inventory
The breeding range of the Balkan warbler extends from the Balkans to Turkey. The Dinaric Mountain range that separates the distribution area of the Balkans warbler from that of the mountain warbler. The European population is estimated at about 28000-108000 breeding pairs. Large populations live, in Greece, Bulgaria and Turkey.
Mainly wooded slopes are chosen as a habitat - areas that would otherwise occupied elsewhere by the related mountain warbler. The altitudinal distribution ranges up to 1800 meters above sea level. The breeding area is populated by early April to September and the species overwinters in East Africa from Sudan to Ethiopia.
