Habitat

Found in high-altitude Andean grasslands (puna) and rocky areas, often near boggy ground or lakes, typically between 3,000 and 4,800 meters (9,800-15,700 feet) above sea level.

Diet

Feeds primarily on insects and other small terrestrial invertebrates, which it gleans or probes from the soil and under rocks using its specialized bill.
