Thanks for the info. The reason I asked is because I have a picture of a bird that gave me an unexpected result from the e-bird photo ID function. I have been looking back at some of my pictures and
remembered taking the picture below a couple of years ago. Looking closely at the lighter colored dove
(which at the time I assumed was a leucistic Eurasian collared dove), I am
wondering whether it could be an African collard dove instead. It has characteristics that support such an
ID. First, it obviously is lighter than
a typical Eurasian collard dove, with little contrast between the primaries and
overall body color. Second, it appears to be smaller headed than ECD (subjective assessment). Third, the mottled feather pattern is often present on [domesticated] ACD (see
eBird
Checklist S60518709 or
eBird Checklist S75581900 ).
I examined pictures of African collared dove from areas of the world (New
Zealand, sub-Saharan Africa, islands east of Madagascar, etc) that do not have any
ECD records and found a number of pictures that match the present bird. Fourth,
e-bird’s photo ID feature ID’ed it as an African collared dove. Finally, there are US e-bird records of ACD that predate ECD colonization in the east, and there
are about 20 previous ACD records for the I-25 corridor. I am not by any means saying that the bird is a natural
vagrant, but rather descendant (or escapee) of a domesticated African collared
dove (i.e., “Barbary dove”). Comments welcome.
Thanks,
