The Clarión wren (Troglodytes tanneri) is a species of bird in the family Troglodytidae. It is endemic to Clarión Island off Pacific Mexico.
It looks much like a house wren but is larger with a prominently longer bill, somewhat approaching the Carolina wren in form.[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. In dense undergrowth, territories are some 10 meters (30–40 ft) in diameter.[2]
In late March 1953, males were found to be singing and threatening intruding competitors. Egg laying takes place between mid-March and mid-April.[2]
The eggs are similar to those of the house wren, but larger and more elongated. 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.[2]
