Galveston County, Texas, US
This bird looks mostly like a Herring Gull but the mantle seems too dark. I can't think of any other species that would better fit than a Herring Gull. Any thought or insight much appreciated.
I was able to rearrange my schedule today and I sent directly to my favorite migrant trap.
I always have trouble with flycatchers, I'll try to figure it out later.
