Townsend, 1890The Clarión Wren (Troglodytes tanneri) is a species of bird in the Troglodytidae family. 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.[1]
Its natural habitats are the less arid patches of shrubland,[2] notably thickets of Ipomoea halierca morning glory.[1] It also appears to occur in the garrison buildings and garden at Sulfur Bay[2] but usually avoids the rocky shores and other exposed areas. In dense undergrowth, territories are some 10 meters (30–40 ft) in diameter.[1]
In late March 1953, males were found to be singing and threatening intruding competitors. Egg-laying seems to take place between mid-March and mid-April.[1]
The eggs are similar to those of the House Wren, but larger and more elongated. They measure around 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.[1]
