Tremblers

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 or Martinique Trembler,Cinclocerthia gutturalis : The Grey Trembler is found only in Martinique and Saint Lucia.
    • Saint Lucia Trembler, Cinclocerthia (gutturalis) macrorhyncha
  • (Southern) Brown Trembler, Cinclocerthia (ruficauda) ruficauda
    • Northern Brown Trembler, Cinclocerthia (ruficauda) tremula

Among the living birds, these are apparently most closely related to the Pearly-eyed Thrasher (Hunt et al. 2001, Barber et al. 2004).

Behavior

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.
