The spotted bamboowren (Psilorhamphus guttatus) is a species of suboscine passerine bird in the tapaculo family Rhinocryptidae. It is the only species placed in the genus Psilorhamphus. It is found in southeastern Brazil, far northeastern Argentina, and possibly Paraguay.
The spotted bamboowren is the only member of its genus and has no subspecies. It has at various times been placed in families Formicariidae (the antthrushes), Sylviidae ("typical" warblers), Thamnophilidae (antbirds), Troglodytidae (wrens), and Polioptilidae (gnatcatchers). Studies of its morphology and later of its genetics have firmly placed it in the tapaculo family.
The spotted bamboowren is genetically most closely related to the rusty-belted tapaculo (Liosceles thoracicus). The spotted bamboowren measures 13.5 cm (5.3 in) in length. Males weigh between 10.5 and 13 g (0.37 and 0.46 oz), while a female specimen weighed 11.5 g (0.41 oz). Adult males have gray heads and upper backs, with brownish lower backs. The throat and upper breast are whitish to buff, transitioning to buff on the lower breast and belly. The back, wings, and belly are speckled with small white, brown, or black... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spotted Bamboowren sighting in Iguaçu National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 309th most-seen of the 346 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 Spotted Bamboowren in Iguaçu National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Spotted Bamboowren 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 2 parks where we can rate Spotted Bamboowren sightings, Iguaçu National Park has the highest daily chance: under 5%. Next come Iguazú National Park (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Spotted Bamboowren is recorded against all the birds logged in Iguaçu National Park (10 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.
