In 2001-2004 investigation was made in Rūdiškės forest, which is a part of Trakai Forest Enterprise, Rūdiškės Forestry. 74 bird species were recorded. They belong to 11 orders. Number of local populations, community structure and their dynamics were investigated in breeding, late summer, autumn migration, wintering and spring migration seasons. The local breeding bird community consists of 62 species. Chaffinch (Fringilla coelebs L.) is an absolute dominate. Chiffchaff (Phylloscopus collybita (Vieill.)), Great Tit (Parus major L.) and Tree Pipit (Anthus trivialis (L.)) are dominants. The lowest number of species of the Rūdiškės forest bird community is characteristic for autumn and winter seasons (31 and 24 species respectively). Fluctuations of numbers of the local populations in the some seasons were statistically not significant in 2001-2004. As an exception, population density of Long-tailed Tit (Aegithalos caudatus (L.)) differed considerably in autumn migration season of the 2001-2003. Variation of numbers of the local population of Great Tit (Parus major L.), Chaffinch (Fringilla coelebs L.) and Eurasian (Treecreeper Certhia familiaris L.) was rather high in spring season as well. Most important factors responsible for habitat selection of Mistle Thrush (Turdus viscivorus L.), Stock Dove (Columba oenas L.), Wood Lark (Lullula arborea L.), Common Redstart (Phoenicurus phoenicurus L.), European Nightjar (Caprimulus europaeus (L.)) and Tengmalm’s Owl (Aegolius funereus...
