Abstract


Introduction. Information about floral cover and terricole vertebrates is absent in the named territory in literature. That is why the review of the nesting avifauna modern state and its links with forest vegetation, which has zonal character, is actual.

Purpose. The investigation of a avifauna and numerous of the Velykoburimsky forestry floral groups.

Methods. Bird censuses has been conducted in May, 2014 in 4 geobotanical profiles in the Velykoburimsky forestry in the National Park «Nyjnosulskyi». 16 forest vegetation descriptions in 5 geobotanical profiles were made according to the school of Brown-Blanke common methodic, from the 3d till 5th of May. 4 floral groups were distinguished: Robinietea, Querco-Fagetea, Alnetea glutinosae class, Prunetalia inclusively the species of broad cenology and ruderals. Ornithology research has been conducted 27-28th of May. Relative record of bird number was made in four geobotanical profies. Linear track length war 1 km (except arboretum – 800 m, data recalculated in 1 km), width - as it was possible to hear and see.

Results. There are 44 species of 7 orders birds were defined: Passeriformes – 30 (68,2%), Piciformes – 5 (11,4%), Columbiformes – 3 (6,8%), Falconiformes – 2 (4,5%), Strigiformes – 2 (4,5%), Apodiformes – 1 (2,3%), Cuculiformes – 1 (2,3%). General number of the birds recorded was 306, in average – 76,5 b./km. There were 3 obvious dominants from the number: Parus major – 55 and 18,0%, Passer montanus – 44 and 14,4% and Fringilla coelebs – 36 and 11,8%. The biggest quantity of species and its number was registered in the arboretum of the village Velyka Burimka- 27 species and 147 ind./km; in the pass Berezove – 20 species and 63 ind./km.; in the pass Mohnach – 20 species and 47 ind./km and in the leafy forest, in the flatland and hill of the Sula right bank-21 species and 50 ind./km. Bird ecomorph test indicated the following distribution. By the nature of nutrition: insectivorous – 28 species and 63,6%, phytivorous – 8 species and 18,2%. Carnivorous and omnivorous – 4 species and 9,1 % accordingly. By the nature of nesting: hollownester- 16 species and 36,4% accordingly, headnesters – 13 species and 29,5%, terricole – 8 species and 18,2% and shrubby – 4 species and 9,2%.

Conclusion. The woods of Velykoburimskyi forestry have an important water-regulation, water-cleaning, fauna-saving function and deserve to be treated carefully in household exploitation as part of newly made nature national park.
