The Itatiaia spinetail (Asthenes moreirae), also known as the Itatiaia thistletail, is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to southeastern Brazil. The Itatiaia spinetail was long placed in the monotypic genus Oreophylax and by some authors in Schizoeaca, but genetic data published in 2011 places it and all other members of Schizoeaca firmly in Asthenes. It has no subspecies.
The Itatiaia spinetail is 18 to 19 cm (7.1 to 7.5 in) long and weighs 10 to 11 g (0.35 to 0.39 oz). It is one of the smaller members of its genus. The sexes have the same plumage. Adults have a mostly dull brown face, sometimes with a faint paler eyering. Their crown, upperparts, wings, and tail are uniformly dark brown. Their tail feathers lack most barbs at the end, giving them a spiny appearance. Their chin and throat are pale dingy buff with a tawny ochraceous patch in the center of the latter. Their underparts are pale buffy brown that is palest in the center of the belly and browner on the flanks. Their iris is brown, their maxilla blackish, their mandible brownish horn, and their legs and feet dark... Wikipedia →

Possible
About 20% of wildlife watchers report an Itatiaia Spinetail sighting in Itatiaia National Park on a given day, based on 461 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 352 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report an Itatiaia Spinetail in Itatiaia National Park on a given day, against about 10% in January and May, the lowest months. That is one of Itatiaia National Park's wettest months, with about 290 mm of rain against 25 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Itatiaia Spinetail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Itatiaia National Park, in our data
Itatiaia National Park is the only park on Wallace's Line with enough records to rate Itatiaia Spinetail sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Furnariidae
The closest relatives of the Itatiaia Spinetail that you can see in Itatiaia National Park (family Furnariidae, Ovenbirds and Woodcreepers) are Olivaceous Woodcreeper (about 50%), Pallid Spinetail (about 40%) and Rufous-capped Spinetail (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Itatiaia Spinetail is recorded against all the birds logged in Itatiaia National Park (461 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.
