Description
In Hungary the Common Goldeneye is a common winter visitor. Occurs predominantly on larger unfrozen wetlands such as Lake Balaton and the Danube, fishponds and gravel pits from October until April. Exceptionally few individuals (presumably injured ones) occasionally stay through the summer. The most important gathering and wintering sites are Lake Balaton, the Danube and Lake Tisza where they can number some thousands.
