A pied harrier?
Dear Stonechat
Though your photo is a bit blurred, it nevertheless affords identification which I am of the
opinion that it is an Eastern marsh harrier for the following reasons:
Structurally, it is wide-winged and proportionally the tail looks a bit short
for a pied.
It is probably a juvenile male for showing no pale rump and and no sharp underwing primary base
contrast which for a pied should be whitish with black towards tips instead of buffy with black
outer part.
So I takes it to be a Eastern marsh harrier.
