Recurvirostra andina
The Andean Avocet (Recurvirostra andina) is a striking, medium-sized wader endemic to the high Andes of South America. Measuring approximately 43-48 cm (17-19 inches) in length with a wingspan of about 68-74 cm (27-29 inches) and weighing 270-340 grams, it is easily identified by its slender, strongly upturned bill, black cap and hindneck, and pure white body with contrasting black markings on its back and wings. Its long, pale blue-grey legs are also a prominent feature. Taxonomically, it be...
Primarily inhabits high-altitude wetlands, saline lakes, shallow lagoons, and marshy edges of the Puna and Altiplano regions, typically at elevations between 3,500 and 5,000 meters.
Feeds primarily on aquatic invertebrates, including insect larvae (especially brine flies), small crustaceans, and other aquatic arthropods, which it filters from shallow water using its specialized bill.
Andean Avocets are largely diurnal, often seen foraging in groups during daylight hours and roosting communally on mudflats or shallow water at night. Their most distinctive foraging strategy involves sweeping their uniquely upcurved bills from side to side through shallow water, tactilely filter...
The Andean Avocet is endemic to the high Andes of South America, with its breeding and year-round range spanning across southern Peru, western Bolivia, northern Chile, and northwestern Argentina. Its core distribution lies within the Altiplano and Puna regions, characterized by vast high-altitude...
Least Concern
