Willet

 

Willets are large, stocky shorebirds with long legs and thick, straight bills considerably longer than the head. Their wings are broader and rounder than those of many shorebirds and the tail is short and squared off at the base.

In summer, Willets are mottled gray, brown, and black; in winter they are a more consistent plain gray. The legs are bluish gray.

Willets are gray or brown birds that, when flying, display a striking white and black stripe along each wing. 

Willets are often seen alone. They walk deliberately, pausing to probe for crabs, worms and other prey in sand and mudflats, or to pick at insects and mollusks.

When startled, they react with a piercing call, often opening their wings and running rather than taking flight. Cornell All About Birds
