This species is a Cerrado obligate. We don’t know how adaptable it is to agricultural changes and the Cerrado has undergone huge transformation to row crops. In Paraguay it is considered critically endangered as it is reliably known from only one site. It is concerning that throughout its potential distribution Nothura maculosa has a relatively large number of records in the Cerrado and Nothura minor almost none. The two species can potentially be confused but still, the difference is telling of a difference in occurence. Given the low number of sightings of the species (while N. maculosa is registered) and the large loss of Cerrado vegetation there is potentially sufficient support to change the status of the species.
I agree with the proposed categorization and criteria.
The habitat loss values calculated over three generations do not reach the threshold required for classification as a threatened species based on suspected population decline at this level. However, historical records show that population decline has been significant over a period exceeding three generations.
Furthermore, the average annual composite rate of forest fires—used as an indicator of habitat loss and degradation—obtained through remote sensing tools available in MapBiomas, is 17.3%. A growing trend in burned area within the species’ distribution polygon is also observed between 2012 and 2024, a period corresponding to three generations.
Given the compiled information, this is the most appropriate classification for the species.
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 22 May 2026. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List category on this page on 22 May 2026, when discussions will re-open.
We thank Jeffrey and Diego for their contributions. Based on available information, our preliminary proposal for the 2026 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 31 May 2026, after which the recommended categorisations will be put forward to IUCN.
The final 2026 Red List categories will be published on the BirdLife and IUCN websites in November 2026, following further checking of information relevant to the assessments by both BirdLife and IUCN.
I agree with the proposal. The species is sensitive to fire and fire-induced changes in habitat, and may also be sensitive to reductions in mammal (armadillo) populations caused by hunting. Fire patterns are changing as a result of human activity (including human-caused climate change) and this species merits increased conservation attention.
