- Title
Predation of Eared Grebe by Great Blue Heron.
- Authors
Rivers, James W.; Kuehn, Michael J.
- Abstract
Great Blue Herons (Ardea herodias) typically prey upon fish and other aquatic organisms, and they occasionally take small mammals and birds. We observed a Great Blue Heron attack, kill, and attempt to consume an Eared Grebe (Podiceps nigricollis). The heron was unable to swallow the grebe, and it abandoned the carcass after approximately 30 min. An examination of the carcass showed that the grebe lacked obvious physical deformities, Our observation, coupled with a similar one nearby, indicates that Great Blue Herons attack and kill birds larger than reported previously.
