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.

Possible
About 20% of wildlife watchers report a Ruddy-tailed Flycatcher sighting in Darién National Park on a given day, based on 76 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 397 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January, April and September
In those months about 30% of wildlife watchers report a Ruddy-tailed Flycatcher in Darién National Park on a given day, against under 5% in May and June, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Ruddy-tailed Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 27 parks where we can rate Ruddy-tailed Flycatcher sightings, Darién National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Soberanía National Park (Panama, about 20%).
Same family: Tyrannidae
The closest relatives of the Ruddy-tailed Flycatcher that you can see in Darién National Park (family Tyrannidae, Tyrant Flycatchers) are Bright-rumped Attila (about 20%), Tropical Kingbird (about 20%) and Acadian Flycatcher (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ruddy-tailed Flycatcher is recorded against all the birds logged in Darién National Park (76 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.
