Large, boldly patterned, and often noisy ibis. Common and conspicuous in cooler and wetter regions of southern Chile and Argentina; uncommon and more local in northern areas. No similar species in range. Favors open country, especially wet grasslands, but also ranges to open forest and beaches. Nests colonially in trees and on cliffs, including in towns and even cites. Soars easily on broad wings, sometimes high with kettles of vultures. Loud trumpeting cries carry long distances.
