Franklin's Gulls at the Wastewater

To Mich-listers, 12:57 pm, May 25, 2016:

I found two Franklin's Gulls at Muskegon Wastewater System.  Right now they are loafing in the middle aeration cell along with Ring-billed Gulls.  They have broad white eye-arcs, large white primary tips and their back and wings are darker gray than the RBGs.  They are also smaller than the RBGs.  Will include photos with my eBird post.  - Laurence Burke
