Christmas emerald dove
The Christmas emerald dove (''Chalcophaps indica natalis''), also known as the Christmas green-winged pigeon, is a bird in the pigeon family, Columbidae. It is a distinctive subspecies of the emerald dove that is endemic to Christmas Island, an Australian territory in the eastern Indian Ocean.
==Description==
The Christmas emerald dove is a small brownish pigeon with green wings. It is some 23–26 cm long, with a 43–46 cm wingspan and a weight of 80-135 g. It is smaller than the mainland Australian subspecies of the dove and differs from them by the adult male having a contrasting light grey cap, with a prominent white forehead, white supercilium extending behind the eye, and a mainly rufous-brown shoulder patch with only a narrow white line along the edge. The adult female has a darker, red-brown head, neck and underparts, lacking the grey and white on the head as well as the pale shoulder patch.〔Higgins & Davies, p.873.〕〔Chasen, p.62.〕
