California Gull, Hammonasset State Park, 3/22/16

California Gull, Hammonasset State Park, 3/22/16.  Discovered by Stefan Martin on 3/21/16, this bird has been seen for the past 3 days.  It's a first cycle gull transitioning into 2nd cycle: that's why this identification is unexpected..  A first California Gull in Connecticut, and an amazing find.  Photos show CAGU size btw RBGU and HEGU.
