What seems to be a hybrid Lesser Black-backed x Herring Gull this evening in Aberdeen Harbour. My second of the year after a subadult a few months ago.

Looks good; a bit more solid that some, but possibly posture; others have more yellow legs, but also look fine; just for comparison we've now passed 100 "bird-days" for this hybrid in Lothian, though boosted by resident/returning, but also multiple individuals and various imms...
