A large gray and black cuckoo-dove with a distinctive fawn-colored crest which is not visible in flight. Found in primary and secondary forest across its range. Often heard at dawn and dusk giving its characteristic “wwwwwow whoop wow” calls from the canopy. Similar to Pied Cuckoo-Dove, though the two species’ range does not overlap. MacKinlay’s Cuckoo-Dove is smaller, slimmer, brown rather than gray, and has a much longer tail.
