MacKinlay's Cuckoo-Dove

Mackinlay's cuckoo-dove (Macropygia mackinlayi), also known as the spot-breasted cuckoo-dove, is a species of bird in the family Columbidae. It is found in Papua New Guinea, Solomon Islands, and Vanuatu. It is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.

The Mackinlay's cuckoo-dove is a small greyish brown or reddish brown cuckoo-dove; these two distinct color morphs are unique among pigeons. It measures 27 to 31 cm in length, and weighs about 87 g. It has a relatively short beak. The breast feathers have black bases and are bifurcated, the lack of the feather tip exposing adjoining feather bases and giving the breast a spotted appearance. The juvenile is barred, and similar to the female Mackinlay's cuckoo-dove or the juvenile Ambonya cuckoo-dove (Macropygia amboinensis).

The Mackinlay's cuckoo-dove is similar in appearance to the slender-billed cuckoo-dove which is relatively larger, has a longer beak, and its upperparts are darker brown than the buffier underparts. In females of that species, the breast is barred with black above and across, and the breast feathers do not bifurcate.
