Red-shouldered hawks ( Buteo lineatus ) feed primarily on mammals, amphibians, reptiles, and invertebrates, the majority of which are insects and crustaceans, with the latter represented to date only by crayfish.
In 2016, authors observed a red-shouldered hawk attack and dismember another crustacean, the ghost crab ( Ocypode quadrata ), on a coastal beach in South Carolina, USA.
This is the first report of a red-shouldered hawk attacking and presumably consuming any species of crab and the first report of probable ghost crab predation by a raptor in North America.
