The ruddy-tailed flycatcher (Terenotriccus erythrurus) is a small passerine bird in the family Onychorhynchidae. It was previously place in family Tityridae. Its range extends from southeast Mexico south to the Amazon rainforest. It is the only member of the genus Terenotriccus, but some authorities place it in genus Myiobius. However, it differs in voice, behaviour, and structure from members of that group.
The ruddy-tailed flycatcher was formally described and illustrated in 1847 by the German ornithologist Jean Cabanis under the binomial name Myiobius erythrurus. The type locality is Cayenne in French Guiana. The specific epithet combines the Ancient Greek ερυθρος/eruthros meaning "red" with -ουρος/-ouros meaning "-tailed". The ruddy-tailed flycatcher is now the only species placed in the genus Terenotriccus that was introduced in 1905 by the American ornithologist Robert Ridgway. The genus name combines the Ancient Greek τερενος/terenos meaning "soft" or "delicate" with τρικκος/trikkos, an unidentified small bird which in ornithology signifies a tyrant flycatcher.

With luck
About 10% of wildlife watchers report a Ruddy-tailed Flycatcher sighting in Tambopata National Reserve on a given day, based on 317 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 550 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Ruddy-tailed Flycatcher in Tambopata National Reserve on a given day, against under 5% in March–April and November–January, the lowest months. That is one of Tambopata National Reserve's driest months, with about 45 mm of rain against 420 mm in February.

GBIF citizen-science records
It is estimated from how often the Ruddy-tailed Flycatcher is recorded against all the birds logged in Tambopata National Reserve (317 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
