The buff-rumped warbler (Myiothlypis fulvicauda) is a species of bird in the family Parulidae, the New World warblers. It is found from Honduras south to Bolivia. The buff-rumped warbler was formally described in 1825 with the binomial Muscicapa fulvicauda.
The buff-rumped warbler has a complicated taxonomic history since its original description. At some time in the nineteenth century it was reassigned to genus Basileuterus that had been erected in 1848. In 1929 W. E. Clyde Todd erected a new genus, Phaeothlypis, with it as the type species. However, many authors retained it in Basileuterus. In the early twenty-first century several studies confirmed that many species in Phaeothlypis were nested within Basileuterus but that the latter was polyphyletic. By 2007 taxonomic systems had begun to resurrect genus Myiothlypis, which had been erected in 1850, for the buff-rumped warbler and many other species.

Possible
About 30% of wildlife watchers report a Buff-rumped Warbler sighting in Darién National Park on a given day, based on 140 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 397 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 60% of wildlife watchers report a Buff-rumped Warbler in Darién National Park on a given day, against about 10% in August and October–November, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Buff-rumped Warbler 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 32
Of the 32 parks where we can rate Buff-rumped Warbler sightings, Darién National Park ranks 4th at about 30%. The best odds are in Farallones de Cali National Natural Park (Colombia, about 50%), Arenal Volcano National Park (Costa Rica, about 40%) and Braulio Carrillo National Park (Costa Rica, about 30%). All parks ranked.
Same family: Parulidae
The closest relatives of the Buff-rumped Warbler that you can see in Darién National Park (family Parulidae, New World Warblers) are Bay-breasted Warbler (about 20%), Prothonotary Warbler (about 10%) and Yellow Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Buff-rumped Warbler is recorded against all the birds logged in Darién National Park (140 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.
