Their tail is mostly reddish... Wikipedia →

Possible
About 20% of wildlife watchers report an Araucaria Tit-Spinetail sighting in Itatiaia National Park on a given day, based on 310 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th 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.
May
In that month about 40% of wildlife watchers report an Araucaria Tit-Spinetail in Itatiaia National Park on a given day, against about 10% in July and December–January, the lowest months. That is one of Itatiaia National Park's driest months, with about 70 mm of rain against 330 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Araucaria Tit-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 Araucaria Tit-Spinetail sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Furnariidae
The closest relatives of the Araucaria Tit-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 Araucaria Tit-Spinetail is recorded against all the birds logged in Itatiaia National Park (310 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.
