- Cinclocerthia ruficauda
Identification
Distribution
Endemic to the islands of Saba, Barbuda, St. Kitts, Nevis, Montserrat, Guadeloupe, Dominica, St. Vincent & Greneda in the Lesser Antilles. Does not occur in St. Lucia & Martinique contrary to the claims in some books. Several recent reports indicate presence on Antigua.
Taxonomy
Four subspecies are recognized1: ruficauda, pavida, tremula, and tenebrosa.
Hunt et al. 2001 present results that indicate that the Brown Tremblers from Guadeloupe/Montserrat (and probably from islands north of there) and the ones from Dominica/St. Vincent probably represent two different species, both separate from the already widely accepted Gray Trembler.
Habitat
Main habitat is wet forest, sometimes found in second growth, edges, and drier habitat.
Behaviour
Famous for its trembling, which looks similar to the behavior young birds of some other species (e.g. House Sparrow) make when they beg for food or which females make at initiation of mating. However, the Brown Trembler trembles a lot more and in other situations as well.
