Version: 1.0 — Published September 7, 2012


Torrent Tyrannulet is very widespread, and occurs in many protected areas including Rancho Naturalista in Costa Rica, Tambito Nature Reseve in Colombia, Guaramacal National Park in Venezuela, Machu Picchu Historical Sanctuary in Peru, and Madidi National Park in Bolivia (Fitzpatrick 2004). The Torrent Tyrannulet's IUCN Red List status of Torrent Tyrannulet currently is evaluated as Least Concern (BirdLife International 2012).

The relative abundance of Torrent Tyrannulet usually is assessed as common (Hilty and Brown 1986, Stiles and Skutch 1989, Hilty 2003), fairly common to common (Ridgely and Greenfield 2001a), or fairly common (Schulenberg et al. 2010).

Effects of human activity on populations

Siltation in streams and rivers may negatively affect Torrent Tyrannulet. It also has been postulated that observations of Torrent Tyrannulets at unusually low (down to 35-40 m) are indicative of displacement caused by the construction of hydroelectric dams further upstream (Young and Zook 1999).
