Re: Gull Hybrid at Lake Merced

David,

    I think that is a Glaucous-winged x Western, which is much more expected here than a Herring x ? at this time of year. Pale eyes do show up on these hybrids. It is too dark on the back for a Herring x GWGU, the darkness comes from Western genes.

Regards

Alvaro
