The red-billed pigeon (Patagioenas flavirostris) is a relatively large, girth-y pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. 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 largely dark, slate-gray plumage with a more maroon, though sometimes described as purple, head, neck, and wing coverts. They have pale red eyes with an orange orbital ring, along with a red bill with a yellow tip. Noticeably, they don't have iridescent collar plumage. A blue-gray belly and tail coverts, as well as a less brown back, distinguish it from most other species., such as the Ruddy Pigeon and Short-billed Pigeon.[4] The only noticeable difference between males and females is that the females have a duller colored head and neck. Juveniles are often even more dull in color and have dark and dusky shoulders, as well as a more brown mantle and wings
Compared to other birds, they are a more mid-to-large sized bird, growing to be between 30-37 cm (12-15 in.) in length and a weight of 230–425 g (8.1–15.0 oz).

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.
