This odd-looking 2cy large gull was seen at Poolsbrook Country Park, Staveley, Derbyshire, England on 6th December 2018. It has the size of a large Herring Gull and structure of a GBBGu but the mantle comprises clear grey adult-type feathers, (similar in shade or slightly paler than the presumed 'ar...

This odd looking presumed 3cy 'white-winged' gull was videod at Cotham Tip, near Newark, Nottinghamshire, England on 3rd February 2017.

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 undersi...

This odd looking presumed 1cy Herring Gull was videod at Albert Village Lake, Leicestershire, England on 4th September 2015. The complete set of scapulars on the bird's right side is pale grey with very slightly darker internal marking on some of the upper feathers. The appearance is startling! How ...

Many thanks Mars - concise and informative as always. What are the Forum's / GRO's views on whether an unringed adult 'Baltic Gull' (L.f.fuscus) showing all the 'fuscus' features (but also including P10 projecting beyond P9 on the closed wing and no primary moult as well as 'classic' structure and p...
