Abstract: In 2015 selected breeding bird species were investigated in the SPA Wkrzańska Forest in NW Poland (146 km2, 92% of total forest area). In total, 17 species from the EU Birds Directive Appendix 1 and 6 listed in the Polish Red Data Book of Animals, were classified as breeders. This area is a significant breeding site in Poland for the Gadwall Mareca strepera (17–21 pairs; 0.5% of the national population), European Nightjar Caprimulgus europaeus (34–101 pairs; 0.8%), White-tailed Eagle Haliaeetus albicilla (7–8 pairs; 0.6%), Boreal Owl Aegolius funereus (10 territories; 0.5%) and Peregrine Falcon Falco peregrinus (1 pair; 2.5%). Relatively large regional populations (at Pomerania scale) of the Stock Dove Columba oenas (54–63 pairs), Common Crane Grus grus (43–49 pairs), Green Sandpiper Tringa ochropus (27–33 pairs), Red Kite Milvus milvus (6–7 pairs), Eurasian Green Woodpecker Picus viridis (26–32 pairs), Black Woodpecker Dryocopus martius (77–112 pairs) and Middle Spotted Woodpecker Dendrocoptes medius (32–38 pairs) inhabit the SPA Wkrzańska Forest. Forest management serves as the most important threat to the key breeding species of the studied SPA.
