Songs of Rusty Tinamou Crypturellus brevirostris and duetting in Crypturellus species

Summary. Rusty Tinamou Crypturellus brevirostris is an elusive, ground-dwelling bird of terra firme forest. Although widespread across Amazonian Brazil, the Guiana Shield and extreme south-east Colombia, it is everywhere uncommon. Frequently, only its distinctive voice betrays its presence and therefore most contacts with this tinamou are auditory. Here, we analyse the vocalisations of Rusty Tinamou, a primary and secondary song, which may represent duetting between male and female of a mated pair. We also compare and discuss this vocal behaviour with duetting in other Crypturellus species.
