No similar species in its range. Found in woodland, forest, matorral, and farmland with taller trees and hedges; often feeds on the ground. In some areas of central Chile nests in colonies in dirt bluffs, such as along roadsides; elsewhere usually nests in holes drilled in trees. Note the gray crown and plain buffy face (with dark whisker on male), big white rump patch, and yellow shafts to wing feathers (mainly visible in flight). Loud shrieking calls sometimes draw attention.
