Thanks a lot

Hi Alex,
This is a weird bird, at least this kind of plumage we do not see normally. Probably some kind of hybrid involved here? Bird seems to be very pale, what was your estimation of the upperparts in the field?

Hello,

the shade of grey, on the field, was a lot paler than other michahellis around.

Thanks
Alex
