Red-billed Pigeon

识别特征

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. 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.<p>Compared to other birds, they are a more mid-to-large sized bird, growing to be between 30 and 37 cm (12-15 in.) in length and a weight of 230–425 g (8.1–15.0 oz).<p>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.
