Behavior

Introduction

There is very little information on the behavior of Choco Poorwill. This nightjar is crepuscular and nocturnal. Presumably it primarily forages for insects with sallies from the ground or a perch, but it also has been observed flying above the canopy, like a nighthawk, and coming lower at forest edge (Ridgely and Greenfield 2001b). In response to tape playback, a singing male landed repeatedly on exposed perches ca 0.5-1.5 m above the ground (Robbins and Ridgely 1992). Roosting birds were flushed from the ground during the day in second growth adjacent to primary forest (Robbins and Ridgely 1992).

Territoriality

There are no published data on territorial maintenance, or fidelity, or of home range size, for Choco Poorwill. Robbins and Ridgely (1992) reported hearing "seven singing individuals from a small ridge", suggesting locally high densities, but did not give an indication of the area encompassed by this ridge.

Sexual Behavior

Little information; presumably is at least socially monogamous.

Social and interspecific behavior

Choco Poorwill usually is solitary.

Predation

No reports of predation on Choco Poorwill?
