Description of the Bird

Long yellow legs. Head and neck had grayish streaking that continued down the sides a bit, belly white. Back mottled. Beak pointed, dark, about 3 inches or so long, darker at the tip than the base. When the birds flew, there was a flash of white from the tail.
Behaviors: The birds were feeding in a ditch along the east side of Blue Mountain Elementary School on 4/17 and 4/18/13 at about 8 AM. When they flushed, they flew eastward together, giving a two-note TOO-TOO alarm call.

Unfortunately, I spooked these two before I could get my camera ready. I will look for them tomorrow more stealthily!
Call: Two-note alarm in flight: TOO-TOO, TOO-TOO
Plumage: Adult

Similar Species Discussion

Previous Experience

I am very familiar with this species. I lived along the coastline of Rhode Island for six years, where both Lesser and Greaters are common in salt marshes. I have also occasionally seen the Lesser here in Boulder County at various locations, most notably, the lake called Little Gaynor, south of Longmont.
