The red-billed pigeon (Patagioenas flavirostris) is a relatively large, robust species of pigeon. It's breeding range extends from southern Texas, United States, to Costa Rica. It's primarily found throughout coastal and lowland areas of Mexico and Central America. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the pale-vented pigeon.
Red-billed pigeons have a very distinctive call, described to be a long, high-pitched call consisting of a coooo followed by three cuk-c'-c'-coo notes. It follows an ascending sound. When taking off, the birds' wings create a noticeable clapping noise.
