Environmental factors affecting the wintering raptor community in Armenia, Southern Caucasus

摘要: The species–habitat relationships can change during the year because of seasonality resources. Therefore, investigation habitat use by animals in each season plays a fundamental role their conservation. main aim this research was to investigate raptor community that spends winter Armenia, southern Caucasus, and explore its relationship with environmental features, such as land topography. During January 2012, we collected data carrying out 15 roadside counts along which calculated three parameters: relative abundance, species richness, diversity. Then, carried multiple linear regression Information-Theoretic Approach, explain between parameters variables. Besides, computed Canonical Correspondence Analysis (CCA) environment around observations. As general pattern, associated permanent crops, maybe heterogeneity, turn allows them support higher densities prey winter. most abundant Black Kite (Milvus migrans), followed Common Kestrel (Falco tinnunculus) Griffon Vulture (Gyps fulvus). To our knowledge, is one first studies investigating wintering raptors generally studied area breeding migration.
