Opis:
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.

Opis:
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:
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.
