Dombrowski A. 2021. BREEDING BIRD COMMUNITY OF FISH PONDS IN SZOSTEK (SOUTH PODLASIE LOWLAND) IN 2021 – CHANGES AFTER 30 YEARS Kulon 26: 1-17.

Abstract. In 2021, 9 counts of breeding avifauna of fish ponds in Szostek (120 ha) in the Kostrzyń river valley in the Siedlce county (Mazowieckie voivodeship) were conducted using the combined cartographic method. 49 species were breeding in 2021, and the total number of pairs was 446 (37.2pairs/10 ha). The highest density was noted in the Eurasian Reed Warbler Acrocephalus scirpaceus (10 pairs/10 ha: entire fish pond area and 64.4 pairs/10 ha: only reedbeds). The percentage of reedbed species was the highest, i.e., 59.8% of the bird community, and the next most abundant morphological and ecological group were swimming birds accounting for 25.7%. Among trophic groups, the most abundant were insectivorous species constituting 68.5% of the bird community and herbivorous – 14.5%. Between 1990 and 2021, the majority of 26 species (53.1%) increased in their numbers, of which 12 were new species: Whooper Swan Cygnus cygnus, Greylag Goose Anser anser, Common Goldeneye Bucephala clangula, Gadwall Mareca strepera, Garganey Spatula querquedula, Little Bittern Ixobrychus minutus, Common Crane Grus grus, Bearded Reedling Panurus biarmicus, Common Wood Pigeon Columba palumbus, Eurasian Magpie Pica pica, Hooded Crow Corvus cornix, and the Common Starling Sturnus vulgaris. 17 species declined, including 6 breeding species that disappeared from the surveyed area: Eurasian Teal Anas crecca, Northern Shoveler Spatula clypeata, Common Pochard Aythya ferina, Little Ringed Plover Charadrius dubius, Common Snipe Gallinago gallinago, and the Bluethroat Luscinia svecica. During the period 1990-2021, changes in bird species abundance and their causes for most wetland and waterbird species were like those shown on fish ponds of the central part of the South Podlasie Lowland.

Abstract. In 2015-2016 the survey of breeding bird assemblage associated with river beds (wetland Non-Passeriformes and Sand Martin Riparia riparia) was carried out. The study was conducted at the sections of small rivers, each several dozen kilometres long, running through the Mazovian Lowland: Wkra, Liwiec, Pilica, and Wieprz. Two canoe surveys were carried out on each river – in the first half of May and first half of June. 5 to 6-7 species representing the studied group were recorded on these rivers. The Mallard Anas platyrhynchos, Little Ringed Plover Charadrius dubius, Common Sandpiper Actitis hypoleucos, Kingfisher Alcedo atthis, and Sand Martin were recorded on all rivers. Moreover, breeding Goosander Mergus merganser was recorded on three of the surveyed rivers, while a pair of the Mandarin Duck Aix galericulata, probably breeding, was recorded on the Wkra river. On a national scale, the studied rivers were the most important for the Common Sandpiper (Liwiec and Pilica), Sand Martin (Wieprz), and Goosander (Wkra and Pilica).

Abstract. This note reports the abundant occurrence of Hymenoptera species: Scolia sexmaculata documented at the site in the Masurian Lake District (NE Poland). On the lakeside slope of the southern exposure covered with xerothermic vegetation, a swarm of these insects, consisting of ca 50-60 individuals, was found.

Murawski M. 2021. COMMUNAL ROOSTING OF WESTERN MARSH-HARRIERS CIRCUS AERUGINOSUS IN THE AGRICULTURAL LANDSCAPE OF THE CIECHANÓW UPLAND. Kulon 26: 43-48.

Abstract. On 22 August 2020 field observations were carried out in the agricultural landscape of the Ciechanów and Przasnysz counties. A roost of 36 individuals of the Western Marsh-harrier Circus aeruginosus was found near Golany (Przasnysz municipality, Przasnysz county) in a sugar beet field Beta vulgaris subsp. vulgaris overgrown with the common lambsquarters Chenopodium album. Next controls documented the increase in the number of harriers and on 5th September there was a group of 62-65 birds. Several Montagu’s harriers C. pygargus and an adult male of the Pallid Harrier C. macrourus were also recorded at that roosting site. The latter stayed in the area for about 3 weeks and used two roosting sites alternatively. Another roosting site was also found nearby. There were 12 western marsh-harriers, 1-2 Montagu’s harriers, and the aforementioned male Pallid Harrier. On 12 September the large roost near Golany disappeared due to a beet harvest and ploughing the field. The increase in the breeding population of the Western Marsh-harrier in Poland caused by inter alia development of field populations of this species, results in the increasing number of the records of communal roosting in the agricultural landscape. Therefore, efforts should be made to develop counting methods on such roosting sites and to protect the largest regional roosts of the Western Marsh-harrier and Montagu’s Harrier.

Abstract. In 2013-2015 the survey of the Boreal Owl Aegolius funereus was carried out in a large forest complex in the Przasnysz Forest District within the Mława Heights in the North Mazovian Lowland (N53.232891, E20.710468). Each year all tree stands older than 80 years were controlled within the entire forest complex covering 90 km². In different seasons, from 4 to 6 territorial males were detected. All sites were in the northern part of the complex in the so-called Oak Mountains. The number of breeding pairs was not estimated.

Szczypiński P. 2021. HIGH ABUNDANCE OF THE COMMON KESTREL FALCO TINNUNCULUS IN THE MŁAWKA VALLEY (NORTH MAZOVIAN LOWLAND) IN 2020. Kulon 26: 51-56.

Abstract. In 2020 a high breeding abundance of the Common Kestrel Falco tinnunculus was documented in the valley of the Mławka River in the North Mazovian Lowland. 35-36 breeding pairs were recorded on the 100 km² area, of which 31 pairs were within the Natura 2000 SPA “Doliny Wkry i Mławki”. Most of the occupied nests were located on poplars. Broods of kestrels were also recorded in low-lying nests, which is less common in the country, of the Magpie Pica pica, built in shrubs of the grey willow Salix cinerea and common lilac Syringa vulgaris. Kestrels nested locally in loose clusters. In the vicinity of Proszkowo, 11 occupied nests were recorded on an area of 4 km2. A large number of nesting kestrels was probably the result of the high food abundance in the Mławka Valley in 2020.

Abstract. Data on bats captured in ornithological nets during the bird ringing project were collected at the station located on the Rembeza Island (51.97^oN, 21.27^oE) in the Vistula river valley close to Czersk village in 2013-2014 and 2019-2021. Bat species, their sex and age were determined based on photos made by ornithologists. In total, 32 individuals of six species were recorded. The most abundant were: Plecotus auritus (13) and Myotis daubentonii (9), i.e., species foraging close to vegetation or over the water surface, and flying on relatively low height. Species common in the area but flying higher Nyctalus noctula was captured rarely. Rare and valuable species – Myotis dasycneme – was also recorded, and the presence of an adult female suggests the occurrence of a breeding colony in the vicinity of the study site.

Abstract. The analysis of the composition of the Tawny Owl pellets collected at a study site (Stary Chinów, 51^o37’N, 21^o28’E) in the northern part of the Kozienice Forest in 2019-2021 documented 18 species of small mammals. They represented three orders: Soricomorpha (4), Chiroptera (3), and Rodentia (11). The community of small mammals in the study area was relatively rich. The most frequently noted species were: Sorex araneus, Clethrionomys glareolus, Microtus agrestis and Apodemus flavicollis. The populations of rodents of the family Gliridae (Muscardinus avellanarius, Glis glis) and Microtus agrestis living on the study site are relatively abundant as compared to other areas of central Poland.

Abstract. „Nietoperek” bat reserve is one of the largest bat hibernacula in Europe. Over 30,000 bats of from 9 species hibernate there every year. The reserve is in Lubuskie Voivodeship, at the northern edge of the Grey Long-eared Bat range in Poland. Few individuals of this species were observed in „Nietoperek” in the 1980s and 1990s. Later this species was noted only in bunkers placed on the ground in the reserve. Here we report two observations of the Grey Long-eared Bat in „Nietoperek” reserve on 03.02.2017 and 09.02.2019. These observations were in the first half of February, while the coldest temperatures occurred in January. The presence of this species might result from its reaction to cold temperatures in previous weeks.

Abstract. In the middle of January 2021, the survey of terrestrial and waterbird species wintering on the Mazovian Lowland was conducted. The controls covered 18 rivers (in total 1220 km), the largest towns, dam reservoirs, and other smaller water bodies. The results collected on selected river sections and water bodies were submitted to a country-wide project - Wintering Water Bird Survey (MZPW). January 2021 was mild, and throughout the surveyed period the average temperature was around 0°C. 102268 individuals of 48 waterbird species were recorded wintering in the monitored area. The most abundant were: Mallard Anas platyrhynchos (69.8%, N = 71383), Great Cormorant Phalacrocorax carbo (6.8%, N = 6.998), Common Goldeneye Bucephala clangula (4.9%, N = 4969), Goosander Mergus merganser (2.9%, N = 2970), Greylag Goose Anser anser (2.9%, N = 2946), and the Mute Swan Cygnus olor (2.5%, N = 2552). 68 “terrestrial” bird species were recorded and their total number was 29.039 individuals. The most abundant were: Fieldfare Turdus pilaris (20.5% of the total bird number, N = 5957), Eurasian Siskin Spinus spinus (11%, N = 3201), Great Tit Parus major (7.2%, N = 2103), Western Jackdaw Corvus monedula (6.2%, N = 1807), and the Yellowhammer Emberiza citrinella (5.1%, N = 1487). The average bird density was 238 indiv./10 km. 120 volunteers took part in this winter bird survey.
