for those who've given comments after mine and others
I now withdraw my comments for the following reasons.
First the bird does not show primary projection beyond the tertials. What shows beyond the tertials
are just uppertail coverts at a closer look.
Second, the back lacks blackish/dark stripes that contrast with whitish/very pale ones.
However, albiet a buff-bellied, it is certainly atypical for lack of gray overcast on head, headside
and lesser wing coverts.
I would certainly like comments from experts like members of the record committee of the society
to decide the issue.
