Wrens (Troglodytidae)

Grey Wren (Thryothorus griseus) - HBW 10, p. 430

French: Troglodyte gris German: Grauzaunkönig Spanish: Cucarachero Gris
Other common names: Amazon Wren

Taxonomy: Thryophilus griseus Todd, 1925, Hiutanaã, River Purús, Amazonas, Brazil.
Exhibits a number of features (e.g. small size, short tail, grey plumage without prominent facial markings) that are not typical of present genus; although traditionally included here, may well merit separate generic status. Study of its breeding biology and social structure, virtually nothing of which is known, could shed light on its true taxonomic status. Monotypic.

Distribution: SW Amazonas (along R Javari, upper R Juruá, upper R Purús), in W Brazil.
