Abstract: The presented first report of the Rare Birds Panel in Poland includes the data from 2018 and, for some species, also the data from previous years. The report presents data on 35 rare non-breeding species. In the discussed period high or maximum numbers were recorded for e.g. the Red-breasted Goose Branta ruficollis, Egyptian Goose Alopochen aegyptiaca, Black-winged Stilt Himantopus himantopus, Purple Sandpiper Calidris maritima, Black-legged Kittiwake Rissa tridactyla, Blyth’s Reed Warbler Acrocephalus dumetorum, Yellow-browed Warbler Phylloscopus inornatus and Ring Ouzel Turdus torquatus (outside mountains). On the other hand, the relatively low numbers, compared to long-term data, were recorded for e.g. the Red-necked Phalarope Phalaropus lobatus, Eurasian Spoonbill Platalea leucorodia, Homeyer’s Grey Great Shrike Lanius excubitor homeyeri and Horned Lark Eremophila alpestris.

Breeding bird communities of Niecka Nidziańska
Abstract: In 2011–2016 birds were counted at 18 study plots representing typical habitats of Niecka Nidziańska (SE Poland) using the combined mapping method. Densities of birds ranged 46.9–139.6 pairs/10 ha in forests, 95.3–392.6 pairs/10 ha among village buildings, 37.0–48.3 pairs/10 ha in meadows, 16.3–23.0 pairs/10 ha in farmlands, 162.5–182.8 pairs/10 ha in reedbeds and 27.7 pairs/10 ha in xerothermic grasslands. Species richness and densities were higher by 30% and 50%, respectively, in Niecka compared to other macroregions of Lesser Poland Upland. Values of species richness and densities found in the the Nida Valley were higher by 12% and 28%, respectively, compared to mean values in the studied area, while in flooded meadows and villages higher by 48% and 185%, respectively. Densities of some species were high compared to national means, e.g. Yellow Wagtail Motacilla flava – 5.6 pairs/10 ha in a field, Meadow Pipit Anthus pratensis – 7.5 pairs/10 ha and European Stonechat Saxicola rubicola – 1.9 pairs/10 ha in a xerothermic grassland and Barn Swallows Hirundo rustica – 128.2 pairs/10 ha in some villages. In fishpond reedbeds high densities were found for Savi’s Warbler Locustella luscinioides – 12.2 pairs/10 ha, Sedge Warbler Acrocephalus schoenobaenus – 14.5 pairs/10 ha, Eurasian Reed Warbler Acrocephalus scirpaceus – 47.2 pairs/10 ha, Bearded Reedling Panurus biarmicus – 10.7 pairs/10 ha and Reed Bunting Emberiza schoeniclus – 16.2 pairs/10 ha. High species richness and densities result probably from a warm and dry climate, diversity of habitats, abundance of food and extensive model of agriculture and fishing.

Numbers of some breeding waterbirds in the SPA Dolina Środkowej Warty
Przemysław Wylegała, Michał Przystański
Abstract: This work presents population numbers of some birds nesting in the valley of the Warta river in the area of the SPA Natura 2000 Dolina Środkowej Warty. In 2020 breeding birds were counted while canoeing along the Warta section of 155 km within the SPA area. A single count revealed the presence of 10–25 pairs of Goldeneye Bucephala clangula (up to 0.8% of the national population), 20–30 pairs of Common Merganser Mergus merganser (1–2% of the national population), 52 pairs of Common Kingfisher Alcedo atthis (0.8–2.0% of the national population), 16 pairs of Little Ringed Plover Charadrius dubius (0.1–0.3% of the national population) and 3030 pairs of Bank Swallows Riparia riparia (1–2% of the national population). In comparison with the 70s and 90s of the 20th century, the survey revealed a marked decline of the Common Sandpiper Actitis hypoleucos. We did not observe nesting Ringed Plovers Charadrius hiaticula and Little Terns Sternula albifrons, in line with scarce breeding records of these species after 2010. We conclude that the middle section of the Warta river is an important national breeding site for the Goldeneye, Common Merganser, Common Kingfisher and Bank Swallow.
