Abstract The effect of the pyrogenic factor on the avifauna of shelter belts in the north-western part of the Azov Sea region, Ukraine is considered basing on results of the research carried out in 2001–2018. The breeding bird community of shelter belts is composed of 50 species, of them different types of shelter belts support 14–46 species. Changes in the species composition of breeding birds are analysed in subsequent years aft er the fires. The recovery of bird communities is progressing at a slow pace following the regeneration of tree-shrub vegetation and development of consortial relations of birds with dominating tree-shrub species and rook (Corvus frugilegus) colonies. It is established that the vegetation pyrogenic succession is accompanied by deep qualitative and quantitative changes in the structure of breeding avian communities in shelter belts of different type.

SynopsisCoppiced willow supports a much higher density of breeding birds than unmanaged more mature willow. This appears to be because it retains richer vegetation cover, especially in the herb layer, and so provides more breeding and feeding sites for both marsh and woodland birds.

The publication focuses on the study of ecological conditions of bird habitats in the steppe zone of Ukraine. The material is based on the original observations in the north-western part of the Azov Sea region over the period 2009-2018 and on the data from relevant literature sources. The impact of changes in ecological conditions of bird habitats was considered and analyzed. The objectives were to show stages of changes in ecological conditions of the Ukrainian steppe and to carry out a comparative analysis of original ornithological data with the data of other authors.

Global loss of biodiversity is occurring at an alarming rate and is a major issue in current times. Long-term studies offer the possibility to analyse changes in biodiversity and allow assessments of anthropogenic interventions in ecosystems. At present, various studies in most countries show partially strong declines of insect populations. Due to their role as a food source for many organisms it is assumed that declines of insect abundance might have effects on higher trophic levels like insectivorous birds. For reliable statements on relationships between food availability and population trends, systematic and extensive records of breeding birds are necessary. In this study, we analysed the changes in the range of species, biodiversity, and abundance of a breeding bird community over 43 years in a large nature conservation area in southwest Germany (“Lampertheimer Altrhein” near Mannheim). Since 1974, considerable changes in the spectrum of breeding birds have been found, but the overall biodiversity index did not change. Furthermore, 70% of the investigated species showed decreasing numbers of breeding bird territories, and the overall number of territories across species declined by more than 65%. A classification based on the main diet during the breeding period and habitat use revealed strong declines for insectivorous birds in the study area, especially in wetland and open cultivated landscapes.

Shannon’S Diversity Index

In a suburb (c. 100 ha) of Ongwediva, a total of 30 breeding bird species were recorded in 2018. Shannon’s Diversity Index was 2.01. Passer domesticus comprised almost half of all breeding pairs (36.4 pairs / 10 ha). Granivores were by far the most numerous feeding guild, comprising 77.5 % of all birds breeding. Birds nesting on/in buildings were represented by two species only, but they comprised almost half (49.9 %) of all breeding birds. In comparison with other southern African towns, the number of bird species breeding in Ongwediva was low. This was compensated by high population densities of some species.

Selection Of

Breeding bird community was censused in an area of 15.9 ha in 2000/20001, on the shores of Lake of Varese, in an Alno-Ulmion alluvial forest. The mean number of the territories was 93 pairs/10 ha/year and nests of cavity-nesting birds were actively searched for analysing the selection of dead wood.
