The ruddy ground dove (Columbina talpacoti) is a small New World tropical dove. It is a resident breeder from Mexico south to Brazil, Peru and Paraguay, and northern Argentina, and on Trinidad and Tobago. Individual birds can sometimes be seen in the southwestern USA, from southern Texas to southernmost California, primarily during winter. The ruddy ground dove is very common in scrub and other open country, including cultivated land and urban centers, where it can be seen feeding on grain alongside feral pigeons. It builds a solid but sparsely lined cup-shaped stick nest in a tree and lays two white eggs. Incubation is 12–13 days with another 12–14 days to fledging. There may be a second or third brood. Chick mortality through predation and falls from the nest is high. Its flight is fast and direct, with the regular beats and occasional sharp flick of the wings which are characteristic of pigeons in general. Ruddy ground doves are small short-tailed pigeons, long with a weight normally about . Adult males have a pale grey head and neck, and rich rufous upperparts, black-spotted on the wing coverts.
