It might help if you state where you see a bird! I'm assuming Barbados but maybe not? Agree the pale headed bird is Ring-necked Duck. I don't think the male is that species. I think maybe 1st winter male or coming out of eclipse Lesser Scaup?
Thanks all of you. Someone else has also seen these ducks and state they are RND both of them. He must have had them closer than I did to have an unambiguous field id. The images here are increased in size over what the camera captured.
Sorry, but it did say Barbados in the title from the start. I have not changed the title (I don't think I could even if I tried). I think it is just that we are not used to the spacing of items on the page with this new format and it therefore got overlooked.
