American Avocet

Recurvirostra americana

Large304 gWetland

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.

Andean Avocet (Recurvirostra andina)

Andean Avocet

Recurvirostra andina

Large361 gWetland

This avocet has a white head, neck, underparts and rump, and dark brown back, wings and tail. It is similar in size but slightly bulkier than the American avocet, at 43–48 cm (17–19 in) in length and 315–410 g (11.1–14.5 oz) in weight. Average body mass is 361 g (12.7 oz), making it likely the heaviest of the Recurvirostridae family. The thin, grey legs are not as long as with other avocet species, but the long thin black bill is upturned at the end. The sexes are similar, and the juvenile plumage is undescribed.
