The Araucaria tit-spinetail (Leptasthenura setaria) is a Near Threatened species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina and Brazil. For a period in the early twentieth century the Araucaria tit-spinetail was placed by itself in genus Dendrophylax. Research published in 2011 conclusively placed it in Leptasthenura.
The Araucaria tit-spinetail's English name comes from the Araucaria angustifolia ("Brazilian pine"), on which is the bird is totally dependent. The Araucaria tit-spinetail is monotypic. The Araucaria tit-spinetail is 17 to 19 cm (6.7 to 7.5 in) long and weighs about 11 g (0.39 oz). It is a small-bodied, long-tailed furnariid with a short crest and a longish (for the genus) slightly decurved bill. The sexes have the same plumage. Adults have a thin white supercilium on an otherwise black and white striped face. Their crown and crest are blackish with narrow paler streaks. Their upperparts are reddish brown with faint pale streaks on the upper back. Their wings are mostly rufous with wide rufous bases on the otherwise blackish flight feathers. Their tail is mostly reddish... Wikipedia →

Possible
About 20% of wildlife watchers report an Araucaria Tit-Spinetail sighting in Curitiba on a given day, based on 333 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 247 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.
January, March–April, June–July and September
In those months about 30% of wildlife watchers report an Araucaria Tit-Spinetail in Curitiba on a given day, against about 10% in November, the lowest month.

GBIF citizen-science records
It is estimated from how often the Araucaria Tit-Spinetail is recorded against all the birds logged in Curitiba (333 verified sightings), 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.
