Sažetak
The research was conducted on 36 points in the northern area of the Special Nature Reserve Upper Danube. The survey of forest songbird communities was carried out using the point transect method, in parallel with the survey of vegetation characteristic on the same points, using the circular plot method. In total, 50 bird species were recorded, 24 of which (forest
songbirds) underwent qualitative analysis. Investigated points were grouped in three forest types: riparian forest and young and mature hybrid poplar Populus x euroamericana plantations. The average estimated population densities of forest songbirds were 693 pairs per km2. The most abundant species in riparian forests and mature poplar plantations were the Chaffinch Fringilla coelebs and the Great Tit Parus major, while in young poplar plantations,
the most abundant species were the Great Tit, the Blackcap Sylvia atricapilla, and the Greenfinch Chloris chloris. The greatest density and the highest number of species were recorded in the riparian forest, while mature poplar plantations had the greatest diversity and evenness of birds.
