    Opis:
    The objective of this study accomplished a knowledge survey of the Bororo indigenous on the birds of natural occurrence in their territory, Meruri village, who is located in the Mato Grosso State, Brazil, in the Savannah biome, and also the relationship of the indigenous with these birds. As the method for collect, the data were used open and semi-structured interviews. Twenty-two indigenous were interviewed, both genres and different ages. The interviewees mentioned 96 species of birds and they showed wide ecological knowledge regarding these birds. Such relationships are complex, being evidenced by a mythical interaction between the man and the elements of nature. These birds are important elements in the creation of stories, legends, in the Bororo ceremonies and arts. The oral transmission of knowledge occurs across generations.

    Opis:
    The diversity of birds is directly correlated with the structure of the forest. Any interfering with the vegetation produces direct effects on the avifauna through the increase, decrease, or alternation of two key attributes: food and shelter. Thus, the composition of life in the forest is altered as changes occur in vegetation that directly interferes with the population structure of the avifauna, be those changes natural or anthropic. This study was realized in fragments of the Amazon Rainforest, and the main objective was to analyze the behavior of frugivorous and omnivorous birds in three different stages of ecological succession. In forest environments where a vertical stratification of resources occurs, these species are distributed occupying a in a high diversity of trophic niches. The diversity and density of the frugivorous and omnivorous birds in the forest fragments in medium and advanced stage of ecological succession could be directly correlated not only with the structure of the forest, but also to the fact that these birds feed almost exclusively on abundant and easy to find food sources - shrub and tree fruit of certain vegetable species that are naturally abundant in the rainforest understory layer.

    Opis:
    This study focused on bird species richness and diversity in Borgu sector, Kainji Lake National Park, Nigeria. The study was undertaken to derive information on the species of birds utilizing the study area, and to determine the relative abundance and diversity of birds in the study area. The Line transect methods was used for the study. The result revealed that the present number and kinds of birds species in all the ranges sampled is very low, with Range 4 having the highest bird’s species richness of (22.29%). A total of 3255 birds were inventoried in all the ranges. These belonged to 44 species from 28 families. Family Ardeidae contain the highest number of 593 birds, followed by the family Sturnidae and Numididae - having 392 and 351 birds, respectively. The findings indicate that birds’ abundance is very low with many bird species displaying 0% relative abundance. The low abundance and diversity of birds indicates that Kainji Lake National Park birds in relation to habitat characteristics is very poor. Furthermore, the result from the test prediction Output shows that the estimators predict that (after 5 samples) there will be 41 birds’ family species in the habitat in future, since they (ACE, ICE, Chao2, Jack2) level off at 41. The result indicate that only the same birds species, instead of new birds species are presently seen in Kainji Lake National Park, which are poorly represented among 28 families sampled. It is, therefore, recommended that environmental education campaign on birds’ conservation and protection should be carried out in the communities around the park so as to persuade residents to stop killing birds.

    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.

    Opis:
    The study is based on the avian community observed in the region. In total, 524 individuals, 27 genera and 35 species of birds belonging to 21 families have been recorded. Among them, the family Charadriidae with 15.08% incidence is the most frequent; immediately followed by the family Scolopacidae (11.26% of occurence). The highest observed species richness has been observed in case of the family Ardeidae. Little Ringed Plover (Charadrius dubius) is the most abundant avian species observed. The community consists of 40% Resident; 40% Resident-migrant and 20% Migrant bird species. It was observed that the concerned community shows a considerable diversity and a corresponding low value of dominance. In the feeding guild analysis, the Insectivore and the Aquatic invertebrate-feeder guilds have the most number of recorded avian species. The feeding guild affiliations also points out that the overall community is fairly rich in its composition as it houses bird species belonging to various feeding guilds.

    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.
