First photographic documentation of Dendrocolaptes sanctithomae preying on a frog

While typically insectivorous avian species may occasionally consume small vertebrates, it is still a rarely directly observed phenomenon, limited to few species. Herein I report what is apparently the first incident of a northern barred woodcreeper (Dendrocolaptidae, Dendrocolaptes sanctithomae) catching a frog. The observation reported was made on the 3 August 2014 at Jalova Biological Station, Tortuguero National Park, Costa Rica. This observation is a useful addition to the scant knowledge on predation on vertebrates by tropical passerines.
