Re: [cobirds] "Small gull with M pattern"

Also yet the Sibley app states "pied wing pattern resembles dark M of other species" in description of Juvenile Sabine's Gull, but let us note that the juvenile wing pattern is the same as the adult wing pattern.

Yet, the Cornell app "Merlin" uses the convenient descriptor "Small gull with distinctive bold "M" pattern on wings in flight, formed by black outer primaries, white inner flight feathers, and dark back," in its description of Sabine's Gull.

All:

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."
