Summary

In early 2016, we conducted bird surveys on the island of Bioko, Equatorial Guinea. We found numerous taxa at different elevations and abundance from those previously reported. We recorded five species new for Bioko (African Jacana Actophilornis africanus, Bat Hawk Macheiramphus alcinus, Western Marsh Harrier Circus aeruginosus, Ethiopian Swallow Hirundo aethiopica and Preuss’s Cliff Swallow Petrochelidon preussi) and one species new for Equatorial Guinea (Great Reed Warbler Acrocephalus arundinaceus).
