Red-bellied Woodpeckers consumiendo carrona: una posible alternativa de dieta

Red-bellied Woodpeckers (Melanerpes carolinus) are insectivores that consume mainly insects found within trees but may also feed on seeds and small vertebrates. On rare, isolated occasions. Red-bellied Woodpeckers opportunistically scavenge carcasses or carrion. Here we document the first recorded instances of repeated and sustained visits by Red-bellied Woodpeckers to a deer carcass presumably for the supplementation of diet via scavenging. Between December 2016 and March 2017, a tree-mounted, motion sensor trail camera directed toward a deer carcass, on a site in Winona, Minnesota, captured 1,815 photos of Red-bellied Woodpeckers from 381 separate visits. We analyzed the photos to determine if time of day or month affected the frequency of pictures of Red-bellied Woodpeckers at the carcass. The timing of Red-bellied Woodpecker visits was not uniformly distributed with more pictures being taken during the middle of the day; however, the frequency of photographs did not differ by survey month. Results of this study are useful for expanding our understanding of Red-bellied Woodpecker diets and the role that scavenging may play in diet supplementation during winter.
