Andean Avocet

The Andean avocet (Recurvirostra andina) is a large wader in the avocet and stilt bird family, Recurvirostridae. It is resident in the Andes, breeding above 3500 m in northwestern Argentina, western Bolivia, northern Chile and southern Peru. 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 in length and 315–410 g in weight. Average body mass is 361 g, 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. The colour pattern is similar to that of the local subspecies Himantopus himantopus melanurus of black-winged stilt, but that bird has very long red legs a white tail and a straight bill.
