    Opis:
    This paper presents an overview of bird research carried out in the Borki Primeval Forest during the last 30 years. The Borki Primeval Forest can be considered as one of the most important forest bird sites in Poland. Its avifauna comprises 139 breeding species, including 11 rare and endangered species listed in the Polish Red Data Book of Animals as well as 30 species listed in Annex I of the EU Birds Directive. Despite its relatively small area, the Borki Primeval Forest holds at least 1% of Polish breeding population of as many as 12 bird species . For seven out of these species it is one of the most important breeding sites in the country. The avifauna of the Borki Primeval Forest consists mostly of typical forest birds including 24 indicator species which are associated with natural forests. The richness of bird species in the Borki Primeval Forest and the abundance of several valuable groups of breeding species are the result of a high landscape and habitat diversity as well as a relatively small anthropopression combined with a high degree of naturalness of forest stands.

    bird assemblage structure
    species richness
    density changes
    forest habitats
    Opis:
    The composition and structure of the breeding bird community in the Borki Forest in north-eastern Poland were investigated during two separate periods: 1994–1996 and 2012–2014. Bird censuses were carried out in three plots located in mature oak-hornbeam, ash-alder and mixed coniferous forest stands. A standard combined mapping technique for estimating the number of breeding birds was applied. A total of 74 bird species bred at least once within any plot during 1994–1996 or 2012–2014. The structure of the bird assemblages on particular plots displayed a high degree of similarity, exceeding 75%, which means that they represent essentially the same bird community. However, the investigated assemblages have changed substantially over the 20 years. Both, the number of breeding bird species and the population densities on all plots, were much higher in 2012–2014 than in 1994–1996. The mean number of breeding species on all plots was over 50% higher in 2012–2014 than in 1994–1996, whereas the mean total density of breeding pairs increased by more than 60%. Total population densities on the plots increased as a result of an increase in population densities of individual bird species combined with an increase in the number of breeding species. Due to different rates of population growth for certain species, also the composition of dominating species group have changed. The observed changes in the avifauna of the Borki Forest were most probably due to an enrichment of the forest habitats structure, which was caused by natural factors, such as ageing of forest stands, forest succession and a change in water regime by beaver dams, as well as by forest management, including group felling within or in the vicinity of plots and uncovering of the forest edge.

    Opis:
    The aim of the study was to combine and summarize data on rare species of breeding forest birds found in the area of the Experimental Forest District near the Rogów village (Łódź Province). Our study area comprised 230 km2 of field and forest mosaic, where forests accounted for almost 17% of the area (13 forest complexes of 37–1000 ha). The results are based on the authors’ own field observations from the years 2000–2015 as well as historical data since 1949 including original research papers, diploma theses, unpublished manuscripts, oral information and analyses of museum collections. The following criteria were used to categorize bird species as rare: (1) species that ceased breeding in the area, (2) taxa that were under strict protection and their abundance was no higher than 6 breeding pairs. In overall, 10 species were classified as rare, of which three do not breed in the area any more: grey heron Ardea cinerea, osprey Pandion haliaetus, European roller Coracias garrulus. However, non-breeding individuals of grey heron and osprey are still recorded in the area (the last cases of breeding pairs were recorded in the 1970s and 1961, respectively), while the European roller went extinct. In recent years, the abundance of another three species was probably stable: European honey buzzard Pernis apivorus, Eurasian hobby Falco subbuteo and nightjar Caprimulgus europaeus. Four species started breeding in the last 30 years: black stork Ciconia nigra, white-tailed eagle Haliaeetus albicilla, common crane Grus grus, stock dove Columba oenas. The trends in the abundance of the investigated species are similar to those observed in the country in overall.

    secondary hole-nesting birds
    Opis:
    In 2011–2014, the occupancy of nest-boxes by secondary hole-nesting birds and their breeding success was investigated in pine stands of the Augustów Forest (North-Eastern Poland). In the studied area of 12600 ha, the share of Scots Pine Pinus sylvestris L. in the stands was 92%. On average, birds occupied 54% and bats 3% of the 224–317 nest boxes controlled yearly. Nest boxes were also used by the Pygmy Owl Glaucidium passerinum L. as food caches. In total, broods of nine secondary hole-nesting species were observed, but only four bird species nested in each year of study. The most numerous species, occupying 53–60% of all boxes each year was the Pied Flycatcher Ficedula hypoleuca Pall. The Great Tit Parus major L. occupied 15–24% and the Coal Tit Periparus ater L. 10–12% of available nest-boxes, while the Redstart Phoenicurus phoenicurus L. used 2–7% of nest boxes. The yearly breeding success was highest for tits (Great Tit – 52–84%, Coal Tit – 50–72%) and strongly variable for the Pied Flycatchers – 38–78%. Broods were lost due to predation by martens Martes sp. (38%) and great spotted woodpeckers Dendrocopos major L. (6%) as well as nest competition (2%). The nest-boxes were occupied at a constant rate during the following four years after their exposition. Over 67% of the new nest-boxes were occupied annually which means new nest-boxes (up to 4 years) were occupied significantly more often than boxes older than 4 years.
