the lower Amazon. In elevation it ranges from sea level to but is usually found below . Behavior Feeding The collared puffbird hunts by sallying from a shaded perch to pluck prey from foliage, bark, or the forest floor. Its prey includes lizards, snakes, frogs, and several types of large insects. It sometimes joins mixed-species foraging flocks and less often follows army ant swarms. Breeding The collared puffbird's breeding season spans at least May to September. It lays its two glossy white eggs in a cavity excavated in an arboreal termitarium or rotted tree trunk. Vocalization The collared puffbird's song is "a repeated, brisk, mewing 'cua-will, cua-will…' or 'awww awwAWW-chaw awwAWW-chaw awwAWW-chaw, and is mainly given at or just before dawn. It is frequently sung as a duet. Status The IUCN has assessed the collared puffbird as being of Least Concern. It has an extremely large range; however, its population has not been quantified and is believed to be decreasing. It is considered common in much of Brazil and rare to uncommon in the western part of its range. It occurs in several protected areas but seems to be highly sensitive to habitat disturbance outside of them.
