I just got a call from Gary Allport who is looking at a yet another Franklin's Gull on the Hains Pt. Golf Course!  He said it is in 2nd summer plumage - fully hooded but with some brown feathers in the coverts or tertials (can't remember which).  This means it's the 3rd Franklin's to show up in DC since May 3rd.

He said the bird is about 5 minutes walk down the golf course on the Washington channel side.  The gate is closed but you can walk the roads.

Good birding,
