2 hybrid Herring x Lesser Black-backed Gulls at Seafield, Edinburgh

Both Herring x Lesser Black-backed Gull hybrids* were in among the gulls at Seafield today. Though it took quite a number of hours before the sub-adult (above) appeared on one of the factory roofs. This bird has a particularly broad band on P5, which would be a pro-YLG characteristic. As a sub-adult though we might expect a little more black on the wing of the hybrid as well. Through the scope the dark eye and dark marks on the primary coverts were clear - the latter are obscured in these shots, although the third (blurry) iphone-scope pic shows the width of the band.

*I am assuming that these two birds are both hybrids, rather than Yellow-legged Gulls...

Here are some shots of the adult bird from today. Seen on rooftops and in flight.
