The rufous-tailed xenops (Microxenops milleri) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, Venezuela, and possibly
French Guiana. The rufous-tailed xenops was originally placed in genus Microxenops, which in the 1950s was merged into Xenops. By 2011 genetic data showed that it did not belong in Xenops and the previous Microxenops was restored.
The rufous-tailed xenops is the only member of its genus and has no subspecies. The rufous-tailed xenops is 10 to 11 cm (3.9 to 4.3 in) long and weighs 12 to 13 g (0.42 to 0.46 oz). It has a thin straight bill. The sexes are alike. Adults have a mostly blackish brown face with a buff supercilium. Their crown is blackish brown with golden-buff feather shafts. Their back is dark rufescent brown with wide buff streaks that fade by the lower back. Their rump and uppertail coverts are rufescent. Their tail is dark rufous. Their wing coverts are blackish with rufescent brown edges and their flight feathers are blackish with a wide rufous band at their base. Their chin and throat are pale... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-tailed Xenops sighting in Manu National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 492nd most-seen of the 641 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rufous-tailed Xenops 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 Rufous-tailed Xenops sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Rufous-tailed Xenops sightings, Manu National Park has the highest daily chance: under 5%. Next come Tambopata National Reserve (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Rufous-tailed Xenops is recorded against all the birds logged in Manu National Park (34 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.
