Mistletoe Tyrannulet Zimmerius parvus

  • Order: Passeriformes
  • Family: Tyrannidae
  • Monotypic
  • Authors: Andrew W. Jones



Mistletoe Tyrannulet moves fairly rapidly through vegetation, searching very actively for food, with the tail often held straight out or upward. The behavior generally is "lively and animated", and this tyrannulet often stands "with legs seemingly extended to maximum extent with the tail cocked" (Stiles and Skutch 1989). Mistletoe Tyrannulet forages at all levels of the forest, but primarily in the middle and high canopy.


Typically encountered singly or in pairs. There are no published data on territorial defense, maintenance, or fidelity, or on home range size, for Mistletoe Tyrannulet.

Sexual Behavior

Undescribed; Mistletoe Tyrannulet presumably is at least socially monogamous.


No reports of predation on Mistletoe Tyrannulet.
