Abstract: The report of the Rare Birds Panel presents abundance estimates for 32 rare breeding taxa (30 species and 2 subspecies) in Poland for 2019. The high or maximum numbers were recorded for: the Whooper Swan Cygnus cygnus (190 pairs), Egyptian Goose Alopochen aegyptiaca (27 p.), Red-crested Pochard Netta rufina (52 p.), Ferruginous Duck Aythya nyroca (131 p.), Mandarin Duck Aix galericulata (96 p.), Great Snipe Gallinago media (345 males), Black-crowned Night Heron Nycticorax nycticorax (1293 p.), Great Egret Ardea alba (378 p.), Great Grey Owl Strix nebulosa (10 p.), Peregrine Falcon Falco peregrinus (49 p.) and Aquatic Warbler Acrocephalus paludicola (4500 m.). The declining trend concerned the Mediterranean Gull Ichthyaetus melanocephalus (42 p.), Western Osprey Pandion haliaaetus (27 p.) and European Roller Coracias garrulus (13 p.). The population of the Eurasian Oystercatcher Haematopus ostralegus (26 p.), Eurasian Curlew Numenius arquata (167 p.), Greater Spotted Eagle Clanga clanga (17 p.; including 8 pure pairs) and Golden Eagle Aquila chrysaetos (33 p.) remained stable. The population of the Sandwich Tern Thalasseus sandvicensis (130 p.) failed to produce any young. Outside the Biebrza Marshes 35 p. of the Citrine Wagtail Motacilla citreola were found. No more than 5 pairs were recorded for the Canada Goose Branta canadensis (1 p.), Black-winged Stilt Himantopus himantopus (1 p.), Short-toed Snake Eagle Circaetus gallicus (3 p.), Short-eared Owl Asio flammeus (5 p.), Homeyer’s Grey Great Shrike Lanius excubitor homeyeri (1 p.), Carrion Crow Corvus corone (3 p. mixed with Hooded Crow C. cornix), Wallcreeper Tichodroma muraria (min. 1 p.) and Grey-headed Wagtail M. flava thunbergi (4 p.). There were no breeding records of the Pied Avocet Recurvirostra avosetta, Rose-ringed Parakeet Psittacula krameri, Greenish Warbler Phylloscopus trochiloides and Redwing Turdus iliacus.
