PREDATION BY GRAY CATBIRD ON BROWN THRASHER EGGS

Grey Catbird (Dumetella carolinensis) Science Article 3

abstract

The gray catbird (Dumetella carolinensis) has been documented visiting and breakingthe eggs of artificial nests, but the implications of such observations are unclear because there is little cost in depredating an undefended nest. During the summer of 2001 at Konza Prairie Biological Station, Kansas, we videotaped a gray catbird that broke and consumed at least 1 egg in a brown thrasher (Toxostoma rufum) nest.
