American Robin (Turdus migratorius) Feeds a Nestling Carcass to Nestlings in an Urban Environment

Turdus migratorius (American Robin) is a songbird that commonly eats fruit and invertebrates as an adult and invertebrates as a nestling. This species has only rarely been observed eating vertebrates, or feeding them to nestlings. We observed the first known occurrence of an American Robin feeding a nestling carcass to nestlings. It is unclear if the bird we observed depredated a nest or scavenged a nestling. The observation occurred on the campus of Indiana University in Bloomington, IN, USA. It is currently unknown if urbanization affects the prevalence of this behavior.
