Opis:
Badania prowadzono w subborealnym borze mieszanym, w drzewostanie dojrzałym użytkowanym rębnią gniazdową, w okresie lęgowym ptaków w latach 2004-2006. W pracy uwzględniono powierzchnie drzewostanu dojrzałego z lukami powstałymi po świeżo wykonanym cięciu gniazdowym, oraz powierzchnie z odnowieniem w wieku 5 i 10 lat. W niniejszej pracy postanowiono przeanalizować, w jaki sposób gwałtowna zmiana struktury przestrzennej środowiska leśnego, po wykonaniu rębni częściowej, wpływa na faunę leśną na przykładzie ptaków. Dzięki wykonaniu cięć gniazdowych, powstały środowiska sprzyjające gatunkom ptaków unikających jednolitych, dużych kompleksów leśnych. Spowodowało to pojawienie się większej liczby gatunków i wzrost zróżnicowania gatunkowego aniżeli w dojrzałym drzewostanie. Na wszystkich powierzchniach badawczych, pomimo wykonania cięć, o strukturze populacji ptaków decydowały głównie gatunki leśne. Powierzchnia po cięciu gniazdowym przyciągała niektóre gatunki ptaków leśnych, które zakładały swoje terytoria na gniazdach odnowieniowych lub w ich pobliżu, jednak w zależności od jej wieku. Obecność oraz okres wykonania cięć gniazdowych nie miało znaczenia przy kształtowaniu struktury grup troficznych i gniazdowych ptaków z najbliższego otoczenia gniazd odnowieniowych.
The research was conducted in a subboreal mixed coniferous forest, in a mature tree-stand exploited by group cutting, during nesting periods in the years 2004-2006. Considered for the work were areas of mature tree-stand with gaps created in result of recent group cutting and areas with 5 and 10 year old regenerations of the forest. In this work it was planned to analyze how a rapid change in the spatial structure of forest habitats, after performing a group cutting, influences forest fauna using the example of birds. As an effect of performed group cuttings habitats favoring those bird species which avoid homogeneous, large forest complexes were created. This caused the appearance of higher numbers of species and an increase of species diversity than in a mature treestand. On all research sites, despite the performed cuttings, the structure of birds’ populations was mostly determined by forest species. The area of the group cutting attracted some species of forest birds, which established their territories on forest regeneration sites or near to them, but depending on their age. The presence and time of performing of the group cuttings had no influence on the shaping of the structures of trophic groups and nesting birds in the areas closest to the regeneration sites.

This paper presents the results of the ornithological research performed in the oldest dry coniferous forests of Kampinos National Park (central Poland). The field study took place on three 25-ha-sites overgrown with Scots pine Pinus sylvestris over 150 years old. The species composition of the dominant group was found to differ from that of other forests. Hole-nesters constituted the most important part of the population of birds together with old and mature forest specialists and residents. Hole-nesters were numerously represented (50% of all noted pairs). Old and mature forest specialists constituted 40% of all pairs. Seven species connected to natural forest clearings were also found to be of significant importance. The presence of such ecological groups is proof of the biological balance and diversity of the researched forests.

This paper presents the results of a study of bird populations connected with the oldest forest stands of pine coniferous forests in Kampinoska Forest, where the pine trees are minimum 160 years old. It presents the basic results concerning the distribution, selectiveness and habitat preferences of hole-nesters and the birds connected with old forests in connection with habitat characteristics. The studied areas were dominated by hole-nesters, and a significant share was of birds connected with gaps left after broken trees. A large group was made up by birds which collect invertebrates among trees and then the species which feed on trunks and branches. Large dimensions of pine trees and numerous cracks in bark, cracks in trunks and hollows under windfallen tress served as microhabitats for particular bird species. The index of species diversity and number of pairs were similar in every area, probably due to dozens of years of forest protection, thanks to which similar quantity and quality parameters developed in the areas.

Opis:
This paper presents the results of a bird census in the Morgi forest range in the Kolbuszowa Forest District (SE Poland). The census was conducted using the point−stand method, i.e. a modification of the point count. This modification enabled tailoring the method to the conditions of the Polish forestry, in which forest stand that is the basic unit of silviculture planning and forest management. The aim of the study was to test the new method of bird census in the managed and large−scale forest units, and to evaluate the utility of the results for conservation measures. Based on the list of stands of the Kolbuszowa Forest District, we drew randomly 270 forest stands, taking into account their most important features: dominant species, forest habitat type, age and vertical structure. Bird counts were carried out in spring of 2014 and 2015. Each stand was inspected twice during each season: 1) between April and mid−May, and 2) between mid−May and the first decade of July. In total, 1080 observation (listening) sessions were conducted and each of the stands was inspected four times. As a result, 14 982 bird observations of 15 757 individuals belonging to 113 species were made. In case of 6720 observations, 7186 individuals belonging to 85 species were recorded in the studied stands. The point−stand bird census presented in the paper, which is a forest−range census type, is adequate for use in large−scale forest units. It allows to determine fauna indices that characterise the forest range, together with the most important features of stands.

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.

Opis:
The aim of this study was to review the most important results from the last 40 years of intense ornithological research conducted in the Białowieża Forest. Furthermore, we discuss the threats that may destroy the unique ecology and characteristics of this forest. Studying the avifauna of the Białowieża Forest provides us with a good general knowledge about natural ecological conditions and relationships, which prevailed in temperate European forests in the past. The avifauna of the Białowieża Forest is characterized by features associated with primeval habitats such as the stability of communities over time, high species richness, relatively low densities, high proportion of hole-nesting birds, very high predation pressure and weak, insignificant competition interactions. This emphasizes the importance of predation, excess of nesting sites for cavity nesting birds, high abundance of food, especially for insectivorous species and fluctuation of bird population size due to rodent outbreaks (pulsed resources). The most severe threats for the avifauna of the Białowieża Forest are: rejuvenation of tree stands, removal of dead wood, fragmentation of old-growth stands, change of tree stand composition (reducing the proportion of some tree species). In order to expand our ecological knowledge about birds, we should keep the Białowieża Forest fully protected for years to come. The main priority should be the maintenance of natural processes changing the forest’s species composition.

Opis:
The study embraced 159 nest boxes placed in three different study plots in the Wielkopolski National Park in western Poland. In the first season, 64% of nest boxes were occupied by four species: great tit Parus major, blue tit Cyanistes caeruleus, Eurasian nuthatch Sitta europaea and European pied flycatcher Ficedula hypoleuca. The dominant species were great and blue tits. Over 80% of broods of great tits and blue tits were reared successfully. Birds preferred nest boxes located in plots with domination of oaks and Scots pine and with rich underbrush. Woodpeckers damaged entrances of 70% of the nest boxes, but did not cause any brood losses. In 13% of the boxes nests of hornets, bumblebees and wasps were found. Bumblebees chose boxes with a bird nest material, whereas wasps and hornets avoided sites occupied by the birds. In general, the insects had a small impact on breeding success of birds and caused failure of only 3% of all broods. Obtained results show that nest boxes in forests may increase density of the most common cavity nesters and secure their high breeding success.

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.

Opis:
We analyzed the differences in composition, richness, and abundance of birds in forest fragments of the Atlantic Forest in the São Paulo State, Brazil, and we demonstrated the variations in richness and abundance of birds between different trophic guilds. We used point counts to characterize the avifauna. Sampling was conducted in two seasons: summer and winter of 2020 in a total of 18 hours distributed in 54 samples. A total of 544 contacts were obtained, belonging to 144 bird species distributed among 22 orders and 45 families and categorized in 18 trophic guilds. The omnivores and insectivores birds composed most of the community, occupying the edge and different strata of the forest such as canopy and understory. For each species, we calculated the abundance index value that showed our study site had a large number of species with low index and few species with intermediate to high index compared to the pattern observed in other surveys. Our study area was characterized by high species diversity for both periods studied. The Shannon-Weaver diversity index for our study areas was 4.62. Equitability was high, 0.92, suggesting the number of species registered in our study site represented the maximum capacity the areas can shelter. Our results show that despite being a secondary and fragmented forest the study area was characterized by a diverse avian community. Although the anthropized forest environments are fragmented and isolated by degraded areas and occupied by pastures, agricultural and urban areas, they are important natural environments to maintain bird diversity.

Opis:
The forests along Brazil’s Atlantic coast have undergone extensive transformation from clearing for pastures, eucalyptus forests, agricultural crops, and urban expansion. In this study we described the avian community in a coastal Restinga Forest near the city of Ubatuba, in the São Paulo State, Brazil. The method used to sample the avifauna specimens was the technique of observations per point-counts, and random observations were also carried. The bird’s observations were realized in 84 days during all four seasons out between the years 2005 and 2007 and were registered 142 bird species distributed among 18 orders and 41 families and categorized in 17 trophic guilds. The omnivores and insectivores birds composed most of the community, occupying the edge and different strata of the forest such as canopy and understory. The great abundance of omnivores birds may be directly related to the abundant fruit resources, and also with the great abundance of understory insectivores are indication of the good environmental quality of the studied area.
