Paltry Tyrannulet Zimmerius vilissimus
Version: 1.0 — Published December 15, 2017
Behavior
Introduction
Paltry 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). Forages at all levels of the forest, but primarily in the middle and high canopy.
Territoriality
Typically encountered singly or in pairs. There are no published data on territorial defense, maintenance, or fidelity, or on home range size, for Paltry Tyrannulet.
Sexual Behavior
Undescribed; Paltry Tyrannulet presumably is at least socially monogamous.
Social and interspecific behavior
Paltry Tyrannulets tend to be solitary except when nesting. May join mixed foraging flocks (Hilty and Brown 1986, Hilty 2003). Skutch (1960) observed the male defending the nesting site from other species while the female constructed the nest or incubated.
Predation
No reports of predation on Paltry Tyrannulet.
