Results of one-year studies by the mapping method of breeding communities of birds in a boreal forest association Sphagno Girgensohnii-Piceetum, and in adjacent associations: Carici elongatae-Alnetum and managed 7-15 year old alder forests in spruce forest habitat, are presented. Total density of birds in the complex of habitats surveyed amounted to 60 pairs/10 ha. The following species were dominant: Fringilla coelebs, Erithacus rubecula, Phylloscopus collybita, Sylvia atricapilla and Regulus regulus. Of rare breeding species the following were found: Accipiter nisus, Dendrocopos leucotos, Picoides tridactylus, Carduelis spinus and Loxia curvirostra. The natural bird community of the moss-spruce forest was found to have changed as a result of the small area of the plot and the neighbourhood of managed forests.
