The Revillagigedo Islands were declared a biosphere reserve in 1994 (Stattersfield et al. 1998). There is a plan to eradicate introduced herbivores from ClariÃ³n; pigs and sheep have already been eradicated but rabbits remain (B. Tershy in litt. 1999, Wanless et al. 2009). The Mexican navy restricts access to the island and helps to prevent further introductions (B. Tershy in litt. 1999, B. Tershy and B. Keitt in litt. 2007). Conservation Actions Proposed
Carry out surveys to obtain an up-to-date population estimate. Monitor population trends through regular surveys. Eradicate introduced rabbits from ClariÃ³n. Continue to prevent the introduction of mammalian predators.
Its natural habitats are the less arid patches of shrubland, notably thickets of Ipomoea halierca morning glory. It also appears to occur in the garrison buildings and garden at Sulfur Bay, but usually avoids the rocky shores and other exposed areas. In dense undergrowth, territories are some 10 meters (30–40 ft) in diameter.
In late March 1953, males were found to be singing and threatening intruding competitors. Egg laying takes place between mid-March and mid-April.
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.
