PREDATION OF HOUSE FINCH EGGS BY CACTUS WREN

Abstract

Although the Cactus Wren (Campylorhynchus brunneicapillus), like some other wrens, is well known for destroying other birds’ eggs, it has not been reported eating those eggs. We observed an incident of a Cactus Wren consuming the contents of an egg it took from a House Finch (Haemorhous mexicanus) nest ~25 km southeast of La Paz, Baja California Sur, Mexico.
