American Avocet
Recurvirostra americana
The American avocet measures 40–51 cm (16–20 in) in length, has a wingspan of 68–76 cm (27–30 in) and weighs 275–420 g (9.7–14.8 oz) The bill is black, pointed, and curved slightly upwards towards the tip. It is long, surpassing twice the length of the avocet's small, rounded head. Like many waders, the avocet has long, slender legs and slightly webbed feet. The legs are a pastel grey-blue, giving it its colloquial name, blue shanks. The plumage is black and white on the back, with white on the underbelly.

Pied Avocet
Recurvirostra avosetta
Adults have a striking black-and-white plumage, with a black cap extending to the back of the neck. The primaries are black, with the base of the inner primaries white, while the secondary coverts are dark grey. The rectrices are pale grey-brown in the middle and white elsewhere. The species shows no seasonal plumage variation. The tail is white, and the legs are bluish. The long, black beak is slender and upturned. Sexual dimorphism is subtle and difficult to discern in the field. The male's bill is longer and less curved, while the female's is shorter and more distinctly curved.
