Trembler

Tremblers are a New World group of passerine birds related to mockingbirds and New World catbirds. Like these, they are in the Mimidae family. There are 2-4 species in one genus, Cinclocerthia:


 * Grey Trembler (Martinique Trembler), Cinclocerthia (gutturalis) gutturalis
 * Saint Lucia trembler, Cinclocerthia (gutturalis) macrorhyncha
 * (Southern) Brown Trembler, Cinclocerthia (ruficauda) ruficauda
 * Northern brown trembler, Cinclocerthia (ruficauda) tremula

Among the living birds, they are apparently most closely related to the Pearly-eyed Thrasher.

Their common name comes from their peculiar behavior: if excited, they will show a much more exaggerated version of the wing-flicking also seen in other mimids, for example the Northern Mockingbirds. The tremblers do not just flick their wings, but shake their entire bodies in a trembling motion.
