Juvenile LBB / Herring Gull with white wing-bars.

Post by richard lowe » Sun Aug 28, 2016 2:50 pm

This striking looking bird was videod at Albert Village Lake, Leicestershire, England on 24/08/2016. See attached video-grabs.
White sub-terminal areas on the primaries and wing coverts form neat symmetrical wing-bars which are truly eye-catching! The extreme feather tips are black. Also the underside of the primaries appears unusually whitish / silvery.
I have rarely seen such a neat plumage anomaly - any comments or explanations welcome.
Kind regards, to all, Richard Lowe. (Derbyshire, England.)
P.S. The specific identity is tentative as there appear to be some conflicting plumage characters - any ideas or confirmation welcomed!

The white primary marks are visible here but nowhere near as striking as in flight! (Quite Herring-like here.)

Eye-catching in the extreme for a juvenile large gull! (Greater coverts are almost unmarked.)
