2 Glaucous-winged Gulls at Lake Merritt
This evening, among the Ring-billed and Western Gulls, I saw two
One was where I saw one yesterday evening: on the semicircular divider line
of buoys (or whatever it is) near the gazebo. The other was at the duck
pond near the nature center.
My ebird list includes pics of both. For folks who, like me, have seen few
Glaucous-winged Gulls, the pics might be especially helpful, especially the
one that allows side-by-side comparison of a Ring-billed Gull,
Glaucous-winged Gull, and Western Gull — the relative darkness or lightness
of their grey backs is easy to compare.
