The whiskered myiobius or bearded flycatcher (Myiobius barbatus) is a species of bird in the family Onychorhynchidae, having previously been included in Tyrannidae and Tityridae. Some taxonomic authorities continue to place them with the flycatchers or tityras. The whiskered myiobius is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest.
The whiskered myiobius was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatcher in the genus Muscicapa and coined the binomial name Muscicapa barbata. The specific epithet is from the Latin barbatus meaning "bearded". Gmelin based his description on "Le barbichon de Cayenne" that had been described in 1778 by the French polymath the Comte de Buffon and illustrated with a hand-coloured engraving by François-Nicolas Martinet. The whiskered myiobius is now one of four species placed in the genus Myiobius that was erected in 1839 by George Gray.

With luck
About 10% of wildlife watchers report a Sulphur-rumped Flycatcher sighting in Arenal Volcano National Park on a given day, based on 1,586 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st most-seen of the 503 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September and October
In those months about 20% of wildlife watchers report a Sulphur-rumped Flycatcher in Arenal Volcano National Park on a given day, against about 10% in November to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Sulphur-rumped 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.
4th of 27
Of the 27 parks where we can rate Sulphur-rumped Flycatcher sightings, Arenal Volcano National Park ranks 4th at about 10%.

GBIF citizen-science records
It is estimated from how often the Sulphur-rumped Flycatcher is recorded against all the birds logged in Arenal Volcano National Park (1,586 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.
