Abstract The habitat suitability for the Common Pochard, a duck species in decline, was studied middle reaches of Orel’ River, Central Ukraine, 2015–2017. ducks were counted on their breeding grounds with use ground survey technique. positions individual birds estimated by GPS and plotted Google Earth map. Ecological Niche Factor Analysis (ENFA) applied to assess suitability. Sentinel-2 image used extract 13 ecogeographical variables get two measures ecological niche (marginality...
Abstract European farmland birds show massive large‐scale population declines due to agricultural intensification. Long‐distance migrants are particularly affected as their populations appear undergo larger than those of residents and short‐distance migrants, raising the question about impact non‐breeding environmental conditions potential on annual survival. The whinchat Saxicola rubetra, an Afro‐Palaearctic migrant inhabiting open habitats, has strongly declined over last decades. Most...

Abstract Protandry, or the arrival of males prior to females breeding grounds is a widespread phenomenon in migratory birds though rarely examined related species which its manifestation can vary. European Stonechat and Whinchat are such pair studied with use individual marking North-Eastern Ukraine 1993–2008. An apparent protandry was found but not Stonechat. The difference between dates male female Whinchats (6 days) significant. mean time span territory establishment by subsequent...
The Eurasian Otter (Lutra lutra) in Water Bodies of the Forest-Steppe and Steppe Zones Northeastern Ukraine.-Skorobogatov, Eu
The breeding bird communities in hills with chalk outcrops were studied national nature park ‘Dvorichanskyi’ (Kharkiv region, Eastern Ukraine) 2010–2016 years. birds counted 1–2 times per year by total-area census method at 3 plots of unequal size (17.8, 33.2, and 41.0 ha). total 38 species was recorded. overall mean density 236.7 pairs/km 2 . dominants Red-backed Shrike ( Lanius collurio ) (mean – 38.8 ; relative abundance 16.8%), Eurasian Skylark Alauda arvensis (33.5; 14.3), Yellowhammer...
The valley of Orel’ river, a left bank tributary Dnieper is an important breeding ground for waterfowl and waterbirds in the continental part Ukraine. composition structure communities was estimated by data counts pairs broods on 48 plots 2005–2017 years. changes were revealed comparison with literature periods 1910–1920s 1970–1980s. According to Coot (Fulica atra) (mean density 36,2 pairs/km2), Black-headed Gull (Larus ridibundus) (17,3), Black Tern (Chlidonias niger) (11,7), Great Egret...
The studies of species composition and abundance diurnal birds prey may be quite indicative the state natural ecosystems level impact human-induced factors on their functions. Such are particularly important within protected areas taking into account unfavourable conservation status many group. status, abundance, aspects habitat distribution breeding preferences were studied national nature park ‘Dvorichanskyi’ adjacent territories (750 sq. km, Dvorichanskyi district, Kharkiv Region,...
The problem of coexistence related species within the same communities poses a question how similar are fluctuations their numbers. Whinchat (Saxicola rubetra) and European Stonechat (S. rubicola) is an example such pair phylogenetically bird species, which members foraging guild sit-and-wait insectivores in open habitats. In Ukraine both quite common meadows, steppes, fallow lands other grassland habitats including undisturbed areas nature reserves. North-eastern characteristic hills with...
