Brown Trembler

The brown trembler (Cinclocerthia ruficauda) is a species of bird in the family Mimidae, the mockingbirds and thrashers. It is found on the islands of Saba, St. Kitts, Nevis, Montserrat, Guadeloupe, Dominica and St. Vincent in the Lesser Antilles of the Caribbean Sea. == Taxonomy and systematics == The taxonomy of genus Cinclocerthia is not fully resolved. The International Ornithological Committee (IOC) recognizes the brown trembler and the grey trembler (C. gutturalis). It divides the brown trembler into four subspecies, the nominate C. r. ruficauda, C. r. pavida, C. r. tremula, and C. r. tenebrosa. However, there is significant phylogenetic evidence that brown tremblers from Guadeloupe northwards may represent a separate species (C. tremula) from those on the other islands. Some authors consider tremula to be part of ruficauda == Description == The nominate subspecies of brown trembler is 20.5 to 26 cm (8.1 to 10.2 in) long; males weigh 47.6 to 65.4 g (1.68 to 2.31 oz) and females 42.8 to 71 g (1.51 to 2.50 oz).
