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 (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.
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. The Andean avocet nests near shallow, preferably alkaline lakes in the Andes, often in small groups. The eggs are laid in at least January.

Possible
About 20% of wildlife watchers report an Andean Avocet sighting in Cochabamba on a given day, based on 55 verified sightings from GBIF citizen-science data. It is the 45th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report an Andean Avocet in Cochabamba on a given day, against about 10% in June, August, October and December–March, the lowest months. That is one of Cochabamba's driest months, with about 10 mm of rain against 100 mm in January.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Andean Avocet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Cochabamba, in our data
Cochabamba is the only city on Wallace's Line with enough records to rate Andean Avocet sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Andean Avocet is recorded against all the birds logged in Cochabamba (55 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
