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 species in one genus, Cinclocerthia:
- Gray Trembler, Cinclocerthia gutturalis
- Brown Trembler, Cinclocerthia ruficauda
Among the living birds, these are apparently most closely related to the Pearly-eyed Thrasher (Hunt et al. 2001, Barber et al. 2004).
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.
