The two-banded warbler (Myiothlypis bivittata) is a species of bird in the family Parulidae, the New World warblers. It is found in Argentina, Bolivia, Brazil, Guyana, Peru, and Venezuela. The two-banded warbler was formally described in 1837 with the binomial Muscicapa bivittata. At some time in the nineteenth century it was reassigned to genus Basileuterus that had been erected in 1848. By 2007 taxonomic systems had begun to resurrect genus Myiothlypis, which had been erected in 1850, for the two-banded warbler and many other species.
The two-banded warbler's taxonomy remains unresolved. AviList, the Clements taxonomy, and the South American Classification Committee assign it these three subspecies: However, in 2014 the IOC split the species into two, calling roraimae the "Roraiman warbler" and retaining the English name "two-banded warbler" for bivittata plus argentinae.BirdLife International's Handbook of the Birds of the World (HBW) did the same in 2016. They retain this treatment as of early 2026 and late 2025 respectively.

Rare
Under 5% of wildlife watchers report a Two-banded Warbler sighting in Manu National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 589th most-seen of the 641 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Two-banded Warbler in Manu National Park on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Two-banded Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Two-banded Warbler sightings, Manu National Park ranks 2nd at under 5%. The best odds are in Amboró National Park (Bolivia, about 70%).
GBIF citizen-science records
It is estimated from how often the Two-banded Warbler is recorded against all the birds logged in Manu National Park (11 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.
