Abstract
We held an adult Guadeloupe Woodpecker (Melanerpes herminieri) in captivity for two weeks and documented its tongue movements as it caught grubs placed into holes that had been excavated out of a log. We provide evidence that the Guadeloupe Woodpecker does not spear grubs with its tongue but instead grabs them with the tongue's horny tip, which is barbed and coated with saliva, and pulls them out of the holes.
