oa Journal of East African Natural History - A First Breeding Record of the Cuckoo Falcon in Kenya
The Cuckoo Falcon, Aviceda cuculoides Swainson, is an uncommon, elusive, and little-known bird of prey which has never been thoroughly studied at the nest. Scanty West African observations indicate that it performs a vigorous tumbling and diving display, accompanied by calling and the exhibition of the chestnut underwing coverts; that the nest is probably built afresh annually; and that the incubation period was in one case about 33 days though, as the nest in question failed, this was not certain (J. H. Elgood, pers. comm., Brown & Amadon; in Press).
