Kleptoparasitism of a Red-Cockaded Woodpecker (Picoides borealis) Nest Cavity by a Red-Bellied Woodpecker (Melanerpes carolinus)

摘要

We report the kleptoparasitism of a Picoides borealis (Red-cockaded Woodpecker) cavity by a Melanerpes carolinus (Red-bellied Woodpecker). We believe this is the first video documenting kleptoparasitism of a Red-cockaded Woodpecker nest by a male Red-bellied Woodpecker in which both a nestling and an attending adult Red-cockaded Woodpecker adult were forcibly ejected. The Red-bellied Woodpecker was resolute in its attempt to usurp the nest, reaching into the cavity over 2000 times in an attempt to evict the cavity occupants. The male Red-bellied Woodpecker and his mate took over the cavity soon after. Adult Red-cockaded Woodpeckers continued to visit their nest cavity during diurnal hours for 2 days post-kleptoparasitism. It is important that resource managers incorporate proactive management techniques to lessen the impact of interspecific competition for cavities, especially in smaller or fragmented Red-cockaded Woodpecker populations.
