Subject: [MDBirding] Strange Ring-billed Gull Pics
Hi All. I spent the morning at the Cecil Landfill
and at the North East town Park. Nothing unusual to speak of except for this
Ring billed Gull that stuck out like a sore thumb. I assume its a RbG I should
say. I had California Gull on my mind, but after looking at the pictures, I
can't quite make that happen.
�
Several years of looking at Gulls, this bright
yellow really stuck out. I have never seen a RbG with so much
yellow.
The bird also had a slightly larger and or longer
appearance to me as well. The eye appeared dark from all angles.
