Comportamento

The Inca wren is known to be insectivorous though details of its diet have been little reported. It forages near the ground in bamboo and other dense foliage, usually in pairs but also in groups of up to six individuals. It seldom joins mixed-species foraging flocks.<p>Almost nothing is known about the Inca wren's breeding phenology. Fledglings have been observed in May.<p>Male and female Inca wrens sing duets, "a rich, varied, warbled series of whistled phrases" [1]. One call is "a rich tchp or tchp-er, sometimes in chattered series"[2].
