Cold Edge

Collared Doves, with one preening the other. This species is not as common as it used to be

These birds are clearly a pair. Collins Bird Guide (Svensson et al, 3rd edition) describe Collared Doves as "rather uniformly pale buff-grey with somewhat browner tone on back . . .", but then say "male on average purer pink with faint bluish sheen on head, neck and breast than female, which is more buffish-grey." Personally I cannot see any pink on these birds, but I can see a slight colour difference. I see the grey of the crown and body of right bird (the female?) with a hint of buff, that is not present in the (presumed) male. And I would simply describe the crown and underparts of the male as pure grey.
