The Torrent Tyrannulet is a very small flycatcher; few other flycatchers are smaller like the Black-headed Tody-Flycatcher. The Torrent Tyrannulet inhabits river and torrents in the highlands of Costa Rica, which commonly feature rocks in and alongside the stream. It is rather dull, with overall white to gray body but black wings, tail and face. They catch insects in the air using acrobatic motions. They usually perch on rocks instead of branches, which means they are found close to ground or water level. While spooked easily by an approaching person, standing or sitting motionless for a while allows them to become used to a person’s presence, resulting in natural and even curious behavior. One such time, a bird perched on branch at a distance where my lens would not even focus (less than 2.2 meters away), and would look at me, like it was trying to decipher what I was.
