Western Willet (Catoptrophorus semipalmatus inornatus)
Range: Western and Central North America

Currently lumped with Eastern Willet (Catoptrophorus semipalmatus semipalmatus) but differs in size, proportions, plumage-coloration, voice, range and ecology. Separation of the two under field conditions is difficult due to considerable variation within each of the subspecies (click here for discussion). Considered by some a candidate for splitting. Western Willets breed in the Great Plains and prairie regions of Manitoba, South Dakota and Nebraska.
