American Herring x Glaucous Gull ("Nelson's Gull") 1st cycle, January 14 2007, Sault Ste. Marie landfill, USA. Picture: Kirk Zufelt.

See Kirk's BLOG. In the Anchorage area it can be hard to find any pure large gulls the majority being Glaucous-winged X Herring hybrids. Fortunately in the east hybrids are still an oddity and vastly outnumbered by pure birds.
