The Clarión wren (Troglodytes tanneri) is a species of bird in the family Troglodytidae.

[2] Its natural habitats are the less arid patches of shrubland,[1] notably thickets of Ipomoea halierca morning glory.

[2] It also appears to occur in the garrison buildings and garden at Sulfur Bay,[1] but usually avoids the rocky shores and other exposed areas.

[2] In late March 1953, males were found to be singing and threatening intruding competitors.

They measure approximately 20×14 mm and also are colored basically like those of house wrens but with fewer and crisper markings noticeably denser at the blunt end.
