The ornithofauna of Yörükkirka Lake (Eskişehir)

Abstract

The aim of this study is to provide information on the species list and seasonal diversity of ornithofauna in Yörükki{dotless}rka Lake, Eskişehir. As observation methods, point count and line transect were used. In the study area 96 bird species of which 49 are resident (R), 39 are summer migrant (S), 4 are winter visitor (WV), 4 are passage migrant (PM) were recorded. The results showed that there is a significant difference between the diversity indices of the spring and winter seasons (p=0.005). The most abundant bird species was Fulica atra (Eurasian coot) (81-100%). Overhunting and use of chemicals are the threatening factors on the bird populations in Yörükki{dotless}rka Lake.
