The effect of vegetation and water depth on nest patterns of the Eurasian coot (Fulica atra)

Abstract

Nest characteristics of the Eurasian coot (Fulica atra) and the effect of vegetation and water depth on nest size were investigated. The study was conducted in 2008 on Poyrazlar Lake (Sakarya) in northwest Turkey. Depth and distance from the edge has no effect on internal nest diameter; however, nest height and external diameter are correlated with water depth.
