Abstract:
The authors present a critical survey of the birds recorded from the Białowieża Forest based on their own observations carried out in 1950-1981 and on the data from literature. A total of 226 bird species, the occurrence of which has been sufficiently well documented, are listed. Among them there are such faunistic rarities as Ciconia nigra, Milvus milvus, Aquila clanga, Circus pygargus, Falco peregrinus, Gallinago media, Bubo bubo, Strix nebulosa, Glaucidium passerinum, Locustella luscinioides, Acrocephalus paiudicola, Phylloscopus trochiloides and Regulus ignicapillus. The changes observed in the avian fauna of the Forest and detailed suggestions concerning the conservation of birds in the forest complex are also discussed.
