Spotted Bamboowren Psilorhamphus guttatus Scientific name definitions

The Spotted Bamboowren has enjoyed one of the most turbulent taxonomic histories of any Neotropical bird. While its separate generic status is not in question, Psilorhamphus has been variously placed in the antbirds (Thamnophilidae), wrens (Troglodytidae), and gnatcatchers (Polioptilidae), but skeletal characters and, most recently, genetics have confirmed its placement within the Rhinocryptidae. This species, and genus, is endemic to the Atlantic Forest, where it occurs from southeast Brazil south to extreme northeast Argentina and probably southeast Paraguay. Although its song is quiet, even when the bird is close, and easily overlooked by the inexperienced observer, the species’ highly distinctive vocalizations remain the best means of detecting the Spotted Bamboowren. Despite its name, the Spotted Bamboowren is certainly not confined to patches of bamboo, but is also fond of very dense vine tangles. Pairs often maintain reasonably close contact. Because of the Spotted Bamboowren’s skulking behavior, there is still very much to learn concerning the species’ behavior and ecology.
