First record of common squirrel monkey (Saimiri sciureus) consumption by Great Black Hawk (Urubitinga urubitinga)

Although raptors are known to be among the predators of the squirrel monkey (Saimiri spp.), there is little specific information concerning this interaction. In this short communication, we report the use of a common squirrel monkey (Saimiri sciureus) as a food resource by a Great Black Hawk (Urubitinga urubitinga). Beyond aggregating useful information on the natural history and ecology of both the squirrel monkey and the Great Black Hawk, we also highlight that squirrel monkeys are, on average, heavier than the mammals most commonly consumed by Great Black Hawks.
