7 thoughts on “Araucaria Tit-spinetail (Leptasthenura setaria)”
Least Concern seems appropriate. This was also the conclusion of the last Brazilian national assessment, carried out in 2019 (not yet published).
As Brazil makes up 75% of the species’ EOO (455,500 km² out of 601,000 km²), an extrapolation of the species’ situation in Brazil is justifiable.
According to the national assessment, in Brazil, the destruction of Araucaria forests by agriculture is the main threat to the species, but there is no evidence that this threat is capable of taking it to the thresholds of risk of extinction in the near future.
Update: The national assessment of this species has already been published:

I agree that Least Concern seems appropriate. This is a common and widespread bird. It does have an obligate association with a tree species that is listed as globally Critically Endangered, but this is on the basis of a much longer timescale (three generation lengths for Araucaria angustifolia, or over a century; Thomas 2013), and the Araucaria remains abundant and widespread despite great historical losses.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 12 February 2024. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List status on this page on 12 February 2024, when discussions will re-open.
Based on available information, our preliminary proposal for the 2024 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 18 February 2024, after which the recommended categorisations will be put forward to IUCN.
The final 2024 Red List categories will be published on the BirdLife and IUCN websites in December 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Araucaria Tit-spinetail is recommended to be listed as Least Concern.
Many thanks for everyone who contributed to the 2024.1 GTB Forum process. The final 2024 Red List categories will now be published on the BirdLife and IUCN websites in October 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.
