The structural composition of the forest habitats is considered to be one of the most important factors affecting the breeding bird community composition. Structurally more homogenous forests are usually characterized by lower number of bird species and their densities. This study presents results of a comparison of the breeding bird communities in three Carpathian mountain forests, and the effect of the forest composition on breeding bird species richness and density. There are the bird communities occurring in semi-natural forests: natural mixed forest (NMF) – spruce-beech forest situated ca. 1000 m a.s.l. and UFZ-spruce forest in the upper forest zone (UFZ) up to 1510 m a.s.l., and the managed spruce forest (MSF) at altitude which is similar to NMF. The territory mapping method was used to estimate the number of breeding species and their densities during years 2004– 2006. The species richness as well as the density of breeding bird communities were found to be higher in the semi-natural habitats (33 breeding species; 64.6 breeding pairs 10–1 ha in NMF and 8 breeding species; 57.6 breeding pairs 10–1 ha in UFZ) than in the managed habitat (21 breeding species; 53.6 breeding pairs 10–1 ha). This was true even for the high-elevated study plot despite the fact that the altitude is usually negatively correlated with both the species richness and density.

Avifaunas of three large cities (Hamburg, Berlin and Warsaw) situated in the northern lowlands of Central Europe along an 850-km-long west-east line were compared. Estimates of several species' breeding populations in these cities were used to calculate their densities in the total area of breeding habitat in each city used by the species in question. The relationship of the densities of several common species was compared. Of 39 species analysed, 18 showed higher densities in Hamburg, 4 in Warsaw and 2 in Berlin. A gradient of increasing density from Warsaw to Berlin and Hamburg (Western gradient) was found for 16 species: Columba palumbus, Troglodytes troglodytes, Prunella modularis, Turdus merula, T. philomelos, T. viscivorus, Sylvia atricapilla, Phylloscopus collybita, Ph. trochilus, Regulus regulus, R. ignicapillus, Garrulus glandarius, Parus cristatus, Certhia brachydactyla, Fringilla coelebs, Pyrrhula pyrrhula. An opposite (Eastern) gradient was found for only 3 species: Columba livia f. domestica, Oriolus oriolus and Passer domesticus. Suggested causes for most of the larger differences among the three cities in the densities of particular species are the variation in the richness of vegetation (higher in both German cities) and differences in the stage of synurbization (i.e. adaptation to the urban environment) of specific avian species. In a few cases, factors such as the geographic range of a species, the attitude of humans (in the case of the Feral Pigeon), and specific, slight variations in habitat are put forward to explain the differences found.

The breeding bird community and structural characteristics of vegetation of the last Croatian mediterranean (Istria Penninsula) oak forest (Quercus robur L.) were compared to those in similar continental oak forests in Croatia. The structure and coverage of the vegetation for both forests were estimated. The line transect method was used for analysing bird community and circular plot method for habitat mapping. Densities were calculated for 17 interior forest bird species, giving an average total density of 880.6 ± 81.4 pairs km⁻². In the mediterranean forest typically continental species were missing or present in low densities. Not a single mediterranean species inhabited forest interior. Insectivorous sedentary species dependent on winter prey availability were more numerous in the mediterranean than in continental forest. The results showed that the difference between mediterranean and continental oak forests was greater in quantitative characteristics than in taxonomic composition of the breeding bird community.

Two study areas, 210 ha (A) and 120 ha (B), have been selected. Arable grounds dominated (92%) in the study area A, while meadows (63% in 1989 and 47% in 2003) – in the study area B. The changes in land use in both study areas have occurred in 2003 comparatively with 1989. In the study area A, an increase of the area with maize (from 1.1 ha to 38.4 ha) and oat (from 5.6 to 28.4 ha), and decrease in area of the rape (from 41.3 to 0.3 ha) and root plants (from 16.7 to 6.4 ha) have been recorded, while the clover and broad bean have totally disappeared as cultivated plants. In the study area B, a conversion of some dry meadows into arable grounds and an abandonment of more than half of the remaining area of meadows has been carried out. The landscape in the study area A was more fragmented in 1989 than in 2003, while in the study area B the reverse was true. On average, cereal areas increased – especially wheat (from 1.5 to 2.4 ha), maize (from 0.6 to 3.8 ha) and oat (from 0.6 to 1.9 ha), while rape areas decreased (from 2.0 to 0.3 ha). The mapping method has been employed to show the effect of these changes on breeding bird community in both years (1989 vs. 2003). In the study area A, density (pairs × 100⁻¹ ha) of the Skylark Alauda arvensis (28.1 vs. 17.1) and Marsh Warbler Acrocephalus palustris (12.9 vs. 2.4) has significantly decreased; while that of Corn Bunting Miliaria calandra (1.4 vs. 8.1) and gallinaceous birds (2.9 vs. 8.1) has significantly increased over the last 14 years. The most numerous species in the group of gallinaceous birds, the Common Quail Coturnix coturnix, probably benefits from the enlargement of oat and barley cultivations. The Skylark was negatively affected by the enlargement of study areas with cultivated plants, especially with the wheat and maize. The Corn Bunting has been, probably, positively affected by the enlargement of maize and barley cultivations, as well as from the warming effect. The decline of the Marsh Warbler could have been caused by the decrease of the area with rape cultivations but it may also reflect short-term fluctuations. In the study area B, only densities of the Chaffinch Fringilla coelebs and Blackbird Turdus merula have significantly increased, and no statistically significant declines were recorded. These increases can be linked to changes in the age structure of tree and shrub stands in the existing small forests, clumps and hedgerows, but these species show probably a general increase in numbers over large areas of farmlands in Poland and possibly in some other European countries.
