The Socorro wren is a species of bird in the family Troglodytidae. It is endemic to Socorro Island, Mexico. It was formerly placed in Thryomanes but was moved to Troglodytes considering "manners, song, plumage, etc." and by biogeography and mitochondrial DNA sequence analysis of the MT-NADH dehydrogenase protein 2 gene.
Region

Typical Environment
Occurs only on Socorro Island, where it uses rocky lava fields, ravines, and seasonally dry scrub. It frequents cactus thickets, low shrubs, and edges of secondary growth created by past grazing. The species often forages among rock piles and in crevices, and may approach human habitations in search of insects. It occupies a range of microhabitats from coastal areas to upland scrub and woodland patches.

This island wren is confined to Mexico’s Socorro Island in the Revillagigedo Archipelago. It was formerly placed in Thryomanes but moved to Troglodytes based on song, behavior, plumage, biogeography, and mitochondrial DNA evidence. On the island it is notably bold and inquisitive, often foraging among rocks and low shrubs. Like many island birds, it is vulnerable to habitat alteration and introduced predators.
Temperament
