Subject: [cobirds] "Small gull with M pattern"
The number of species of "small gulls with an M pattern" that are possible in Colorado is five: Ross's, Little, Bonaparte's, and Black-headed gulls and Black-legged Kittiwake. The "M pattern" refers to the "M" described by the dark primaries and the stripe of dark crossing the otherwise pale coverts to the wrist from the base of the wing.
Sabine's Gull does NOT have an "M pattern."
