Abstract. Vocal repertoires of the Common Rosefinch were studied in the Natura 2000 “Kostrzyń Valley” area in 2015. Two different types of songs were recorded and analysed: short and long. Among them 69 different songs were found. 2,304 analysed songs belonged to 63 males. They consisted of 3-9 syllables and lasted for 0.66-2.26 seconds. Most of these songs (81.6%) started with a syllable that was a straight line with increasing frequency. During the recording of an individual male, the changes in the type of song were noted. Local dialects were also identified. The largest was recorded along 4.1 km transect in 14 males.

Abstract. In this paper, we compared microhabitat preferences of two species of terns: Black Tern Chlidonias niger (a non-expansive species) and White-winged Tern Chlidonias leucopterus (an expansive species, new to the region since 1997) on oxbow lakes in eastern Poland. The Black Tern clearly preferred places situated closer to the wall of helophytes and with a larger proportion of such vegetation than at the random sites. While White-winged Tern preferred places situated far from the wall of helophytes and with with deeper water. Probably, White-winged Tern prefers places in the center of the patch of vegetation, because most often there is a lower level of predation pressure. This strategy is unreliable due to the weather, which is responsible for the majority of losses in clutches.

Zakład Planowania Przestrzennego i Badań Ekologicznych EKOS, ul. Traugutta 8, PL-08-110 Siedlce, e-mail: ekos@siedlce.cc.

Abstract. In 1984-1985, a breeding bird survey with the cartographic method was carried out on 4 sample sites (a total of 66.9 ha) in three types of residential areas: old, central part of the town, panel building estate and a district of detached homes in Siedlce. 26 breeding bird species were recorded in total (from 10 to 22 on different sites), and the community density ranged from 93 pairs/10 ha in the panel building estate to 270 pairs/10 ha in the centre of the town (on average 165 pairs/10 ha). The most abundant were: House Sparrow Passer domesticus (72.7 pairs/10 ha, 53.8% in the community), Western Jackdaw Corvus monedula (16.4 and 12.2), Common Starling
Sturnus vulgaris and the Common House Martin Delichon urbicum (9.4 and 7.0, respectively). In 2010 the breeding bird survey was repeated on the same study sites; more breeding species were recorded (30), but their average density was distinctly lower (110 pairs/10 ha). Following species were not recorded as breeding: Common House Martin, Barn Swallow Hirundo rustica, Crested Lark Galerida cristata, Thrush Nightingale Luscinia luscinia and the Willow Warbler Phylloscopus trochilus. In town centre and the panel building estate feral pigeons Columba livia f. urbana started to breed in large numbers, while on all study sites the Common Wood Pigeon Columba palumbus was recorded breeding in moderate numbers. There were also new species recorded, which included: Common Kestrel Falco tinnunculus, Spotted Flycatcher Muscicapa striata, Syrian Woodpecker Dendrocopos syriacus, Common Blackbird Turdus merula, Fieldfare Turdus pilaris, Common Chiffchaff Phylloscopus collybita and the Eurasian Blackcap Sylvia atricapilla. A marked increase in the number of the Common Redstart Phoenicurus phoenicurus, Common Chaffinch Fringilla coelebs, European Serin Serinus serinus, Icterine Warbler Hippolais icterina, Lesser Whitethroat Curruca curruca and the European Goldfinch Carduelis carduelis was also noted. The most distinct changes were observed in the House Sparrow, as its number was 2-4 times lower on 3 sample sites, while in town centre it was even 7 times lower, in the Common Starling (a 2-5-fold decrease) and the Eurasian Tree Sparrow. The number of the Western Jackdaw varied at different sites, but its average density remained at similar level. It was found that the breeding bird communities at four study sites were similar with regard to their species composition, density and dominance in the same breeding season, while they significantly differed when compared between the analysed periods (1984-1985 and 2010). The results of the present study were compared with available data on 18 towns in Poland during 1966-2016 (a total of 77 study sites, where 107 samples were collected). It appeared that the avifauna of urban part of Siedlce was similar regarding the composition of dominant and subdominant species, while it mainly differed when rare and sporadic species were compared. Significant differences in basic parameters that characterized the breeding bird communities (density, percentage share in the community and species frequency) were also documented in three types of residential areas, in different decades during 1961-2016 as well as in the western and eastern part of Poland.

Abstract. In 2012-2014 the Lake Zgorzała located in Ursynów District in Warsaw was reclaimed. This lake disappeared as it was filled up with debris and soil excavated during the development of settlements in Ursynów District. The natural coastline of the lake was restored and the lake was deepened. The construction works commenced with an increase of the maximum area of the lake from 3 ha to 12 ha. Since September 2012 to the middle of 2018, 117 bird species were observed. Out of this number, 50 species were considered breeding or probably breeding. In the group of breeding birds, 20 species represented wetland and waterbird species of Non-Passeriformes. In 2011, i.e., before the reclamation started, 46 species were recorded, which included 15 breeding and 7 probably breeding species. This means that after the reclamation of the lake, the number of all recorded taxa increased 2.5 times, and similar trend was observed in breeding species. The number of breeding wetland and waterbird species increased three times. The restoration of the dome of this reservoir created favourable conditions for migrating Non-Passeriformes. Their number increased from 6 to 23 species. A cost-benefit analysis indicated that the reclamation which involved the restoration of the previous dome of the lake and leaving the part of it for natural succession positively influenced the avifauna of this area.

Abstract. The research was conducted on the 10,406.87 ha Site of Community Importance Cisowsko-Orłowińskie Forests in 2015-2018. The study site included 3 hill ridges of the southern part of the Świętokrzyskie Mountains, along with adjacent areas. Our research concerned the occurrence and distribution of amphibians and reptiles and the existing threats to these animals in the Cisowsko-Orłowińskie Forests. As a result of the research we recorded 14 species of amphibians and 6 species of reptiles at 25 sites. The following species were found: alpine newt Ichthyosaura alpestris, great crested newt Triturus cristatus, smooth newt Lissotriton vulgaris, European fire-bellied toad Bombina bombina, European common spadefoot Pelobates fuscus, common toad Bufo bufo, European green toad Bufotes viridis, European tree frog Hyla arborea, edible frog Pelophylax esculentus, pool frog Pelophylax lessonae, marsh frog Pelophylax ridibundus, moor frog Rana arvalis and common frog Rana temporaria. Reptiles were represented by the sand lizard Lacerta agilis, viviparous lizard Zootoca vivipara, slow worm Anguis fragilis, grass snake Natrix natrix, smooth snake Coronella austriaca and common European adder Vipera berus. The main threats to the Site of Community Importance are posed by overgrowing and drying of small water reservoirs, which are breeding places of amphibians. The other threats include deadly collisions of migrating batrachofauna with cars, grassland fires and pollution of surface waters.

Abstract. The observations were carried out in the area of the Site of Community Importance Suchedniów Forests (total area – 19,120.9 ha) in the years 2016-2018. The Site of Community Importance was established in the northern part of the Świętokrzyskie Province to protect the north-western part of the Świętokrzyska Primeval Forest. The area is characterized by a high environmental and geological diversity. Mild hills are usually overgrown with forests. The research included inventory of amphibians and reptiles, and identification of threats, along with determining necessary protection measures. As a result of the research we recorded 12 species of amphibians and 5 species of reptiles at 23 sites. The following species were found: alpine newt Ichthyosaura alpestris, smooth newt Lissotriton vulgaris, great crested newt Triturus cristatus, European common spadefoot Pelobates fuscus, common toad Bufo bufo, European green toad Bufotes viridis, European tree frog Hyla arborea, edible frog Pelophylax esculentus, pool frog Pelophylax lessonae, marsh frog Pelophylax ridibundus, moor frog Rana arvalis, common frog Rana temporaria, sand lizard Lacerta agilis, viviparous lizard Zootoca vivipara, slow worm Anguis fragilis, grass snake Natrix natrix and common European adder Vipera berus. The main threats to amphibians and reptiles in this area are: drying out of water bodies, water pollution, human presence and road traffic.

Abstract. Species composition and density of ladybird beetles overwintering in two city parks in Warsaw (central Poland) were investigated. Altogether, 186 samples of litter were collected in Park Skaryszewski (88 samples) and Pole Mokotowskie (98 samples) between 16 November 2017 and 10 March 2018. In total, 38 individuals representing 11 species of ladybird beetles were recorded. All species overwintering in litter were previously noted during the surveys of the ladybird diversity in two city parks in the growing season. The densities of overwintering ladybird beetles in city parks (1.8 ind./m² in Park Skaryszewski, 1.3 ind./m² in Pole Mokotowskie) were lower than those in the suburban zone of Warsaw.

Abstract. On 2 April 2017 I recorded a male Green-winged Teal Anas carolinensis during the observations on the wetlands of the Omulew River near Oborczyska (municipality of Baranowo, Mazowieckie voivodeship). I observed the same individual at the same site on 9 April, and again on 21 April also in the Omulew valley, but several kilometres farther in Długie (municipality of Czarnia, Mazowieckie voivodeship). It was the first record of this species on the Mazovian Lowland, and the fifth for Poland. The observation was verified and accepted by the Polish Avifaunistic Commission.

Abstract. In 2011 and 2012, 48 species of wetland birds were recorded on small (about 6.5 ha), ephemeral reservoir localized in the agricultural landscape in the Mazovian Lowland. 6 species were found nesting in the study area, including few pairs of the Little Ringed Plover Charadrius dubius and Common Ringed Plover Charadrius hiaticula. In spring, further 32 species were recorded and during post-breeding movements and autumn passage 34 species were observed. The study area was particularly important for migrant waders. Among them, some uncommon species were observed, for example: Ruddy Turnstone Arenaria interpres, Red-necked Phalarope Phalaropus lobatus and Red Phalarope Phalaropus fulicarius. The results suggest that wetlands in the agricultural landscape may play an important role for wetland birds, especially waders, when their common, feeding habitats (such as shores and shoals at rivers and water bodies) are flooded.

Abstract. The diet composition of the Long-eared Owl Asio otus was examined based on the analysis of owl pellets from two wintering sites in the Łowicz Plain: Bednary Kolonia and Głowno (central Poland). 1970 prey individuals of vertebrates which included 11 species of mammals were identified. The dominant prey were the common vole Microtus arvalis (43.3%), european pine vole M. subterraneus (6.3%), striped field mouse Apodemus agrarius (5.2%) and harvest mouse Micromys minutus (5.0%). Very rare prey were the common shrew Sorex araneus and pygmy shrew S. minutus.

ul. Wincentego Witosa 10/5, PL36-200 Brzozów, e-mail: maciej.turzanski@interia.pl

Abstract. On 12-14 August 2018, intensive feeding of rooks Corvus frugilegus was observed on the outskirts of Brzozów (SE Poland, 49°42’17.19”N, 22°01’35.98”E). Birds were pecking seeds from 21 plants of the garden sunflower Helianthus annuus. Every morning, between 7.50 and 9.00 a.m., several rooks were peeling sunflower seeds – during that time some birds left the site, while the others arrived there. After three days, the largest sunflower heads of a diameter of ≤30 cm were eaten up in about 15-35%, while the younger in about 5-10%. On 14 August in the evening, sunflower heads were covered with tights to protect the seeds from birds. After two days, i.e., on 16 August, rooks began to move and puncture the cover and take out - this time in small amounts - seeds from available parts of sunflower heads. Their feeding lasted until 24 August, when all sunflower heads were harvested. The summer energy balance of an adult Rook was calculated, and was equal to χ = 144 (109-192) kcal/day/individual. This corresponds to a daily intake of χ = 50 g (37.8-66.7) of sunflower seeds. In Poland as well as in other parts of the world, sunflower seeds were recorded in the diet of the Rook, yet in small amounts (low frequency), but during the whole year like in Hungary. The above observations confirm that sunflower seeds constituted only an insignificant and occasional food source for the Rook. The economic importance of this species should always be assessed in a complex way, and should also consider its significant and useful role in agrocenoses.

Abstract. The monitoring of the hazel dormouse Muscardinus avellanarius was carried out in 2014-2018. The monitored area (5 study plots) covered the Strążyska Valley (1 study plot), Spadowa Valley (1 study plot), Chochołowska Valley (2 study plots) and the Kościeliska Valley (1 study plot). Thirty monitoring boxes for the hazel dormouse were hung in each plot. From spring to autumn we regularly checked the boxes to find out if they were settled by the hazel dormouse. The study documented the presence of 4 to 8 nests and from 1 to 3 individuals of the hazel dormouse in four areas. The only unsettled area was localized in the Chochołowska Valley. The results of this monitoring showed that the hazel dormouse inhabited spruce forests located higher in the Kościeliska Valley and on the Huciska Glade in the Chochołowska Valley. The hazel dormouse settlements were also found in beech forests. These new sites of the hazel dormouse documented by our survey in the Western Tatras complement the knowledge of the natural occurrence of the species

Abstract. The study on mammals in diet composition of the Tawny Owl Strix aluco was conducted in Wola Zadybska (SE Mazovia) in 2009-2018. Within 623 vertebrate prey items there were 551 mammals – 88.4% (remaining prey: birds – 31 and amphibians – 41). Rodents clearly dominated mammalian prey (near 95%), and among them Myodes glareolus, Apodemus agrarius, Microtus arvalis and Apodemus flavicollis were most abundant. It is worth noting that the locality of Crocidura leucodon was on the border of its range in Poland. Mammal community in Wola Zadybska is typical for the Mazovian agricultural landscapes with a mosaic of habitats (villages, arable fields and small forests).

Abstract. In December 2015 the members of Warsaw Ringing Group TRIDACTYLUS have started the project of ringing of the Mallard Anas platyrhynchos within the boundaries of the Warsaw metropolitan area. The aim of the project was to study wintering, moult and breeding site fidelity of urban mallards and also the origin of birds wintering in the study area. Between December 2015 and February 2018, 1 471 individuals were ringed at 73 localities. In the same period, 7 710 recoveries of 892 ringed birds were obtained. About a half of reported individuals were observed only at the site of ringing. All the rest were, at least once, reported also from other sites within the study area. Immature individuals changed location more often than adults and males changed it more often than females. So far, only 7 individuals (all males) were reported outside the Warsaw metropolitan area. Four individuals were shot in Russia, one was shot in Belarus and one in NE Poland. One individual was observed alive at the fish ponds in Belarus. From birds reported (ringed or observed) in the winter season 2015/2016 in Warsaw approximately 50% was reported again in winter 2016/2017. From birds reported between April and June in Warsaw, 76% were later wintering in the city and in 24% there are no data about their wintering place. There were no reports of birds which after spending breeding period in Warsaw spent winter elsewhere. The number of data collected during our project is the first such large dataset from the Warsaw metropolitan area and one of the largest in Poland.
