Behavior

Brown Trembler forages on the ground, and in the understory and midstory. On the ground it tosses leaves with the bill (Zusi 1969). More frequently tremblers forage by searching among epiphytes and by poking the bill into spaces betweens vines and tree trunks or by pulling on dead leaves trapped in vegetation (Zusi 1969).

Brown Trembler often cocks the tail. Tremblers derives this name from their most characteristic behavior, trembling, in which the wings both are drooped snd angled slightly away from the body, with primaries slightly open, with the wings making very rapid vertical and lateral motions. Trembling is most often associated with encounters between individuals, and so probably serves as a visual intra-specific signal (Zusi 1969, Markowsky et al. 1994).

There are no published data on territorial defense, maintenance, or home range size for Brown Trembler.

Undescribed. Brown Trembler presumably is at least socially monogamous.

Little information, but forages in groups of up to six individuals (Zusi 1969).

Cats have been known to take other Mimids in the Lesser Antilles, although a cat taking a Brown Trembler has not been reported.
