It is found from Honduras to Panama in Central America, in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay, and on Trinidad.
The white-flanked antwren was described by the French ornithologist Louis Pierre Vieillot in 1817 and given the binomial name Myrmothera axillaris. The white-flanked antwren's taxonomy is unsettled. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World assign it these five subspecies:
The Clements taxonomy adds a sixth subspecies, M. a. luctuosa, that the other two systems treat as a separate species, the silvery-flanked antwren (M. luctuosa). The North and South American Classification Committees of the American Ornithological Society also include the silvery-flanked taxon within the white-flanked antwren. Clements does recognize...

Possible
About 30% of wildlife watchers report a White-flanked Antwren sighting in Serra dos Órgãos National Park on a given day, based on 202 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 336 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a White-flanked Antwren in Serra dos Órgãos National Park on a given day, against about 20% in February, August and November, the lowest months. That is one of Serra dos Órgãos National Park's driest months, with about 50 mm of rain against 310 mm in November.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-flanked Antwren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 25 parks where we can rate White-flanked Antwren sightings, Serra dos Órgãos National Park has the highest daily chance: about 30%. Next come Soberanía National Park (Panama, about 20%) and Brownsberg Nature Park (Suriname, about 20%).
GBIF citizen-science records
It is estimated from how often the White-flanked Antwren is recorded against all the birds logged in Serra dos Órgãos National Park (202 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.
