10 thoughts on “Ochraceous Attila (Attila torridus)”
I have serious doubts about this, given the fact that reliable information on this species is basically non-existent. Assuming that the species’ global population is > 10.000 individuals is quite a long shot! However, the only information available (based on remote sensing and landcover data) do not support including this bird in any threatened category. Until more accurate distributional and ecological information is available (which probably will take quite long time to be available), listing the species as LC seems the only viable thing to do here.
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
Based on available information and following information received from Manuel Sanchez Nivecela, our proposal for the 2024 Red List is to pend the decision on this species and keep the discussion open, while leaving the current Red List category unchanged.
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.
As stated a few months ago, I was not sure about downlisting the species, but available information did not clearly support retaining it as VU. It seems information provided by Manuel helped clarifying this, which is very positive. Will this new information be available at some point to anyone interested in this discussion? It would be nice if the rationale of leaving the current category (VU) unchanged is clear to everyone.

Recommended categorisation to be put forward to IUCN
Following further review, the recommended categorisation for this species has been changed.
Ochraceous Attila is now recommended to be listed as Near Threatened, approaching threatened thresholds under Criterion C2a(i).
Many thanks to those contributing to this topic, in particular the contribution of Manuel Sanchez-Nivecela that helped the reassessment of this species. This information has allowed a further refinement of the map and the personal assessment provided indicated potential suitable habitat totals 17,152 km2 (M. Sanchez-Nivicela in litt. 2024), a value consistent with the habitat area estimated in Colombia of 3,240 km2 (Renjifo et al. 2014) and the small range in Ecuador, 791 km2 (SERFOR 2018). The Colombian Red List (Renjifo et al. 2014), assessing the species as Vulnerable, estimated an AOO of 886 km2 for the small proportion of the range found in that country, a population size of 2,747 mature individuals (noting that the density used, 3.1 per km2 [BirdLife International 2011] is based on territorial individuals) and with 18% habitat loss between 2000-2010. The latter was suspected to imply that rates of population reduction may exceed 30%, because much habitat loss (for cocoa) may be at scales too small to be recorded. The Red Book for Peru (SERFOR 2018) estimates an even smaller distribution in that country, at 791 km2, assessing the species at Vulnerable under criterion D2 due to the threat from habitat loss and degradation. Most of the range lies within Ecuador. The assessment received (M. Sanchez-Nivicela in litt. 2024), gives a suggested AOO value of 1,512 km2 but this appears to be based only on known, collated records and therefore does not account for the potential occupancy of any remaining apparently suitable habitat. While this AOO appears likely to be an underestimate, if, based on the patchy distribution, we make a precautionary assumption that the species only occupies 10% of the identified suitable habitat within its range then the population would be only around 5,300, matching that in the supplied assessment of 5,267 individuals. If the species occupancy is equivalent to the proportion of habitat estimated to be occupied in Colombia, at 27%, the population would number 14,360 mature individuals. However, based on the patchy occurrence of records through the range and an assumption than dispersal is limited there are, as noted above, considered to be several subpopulations. A continuing decline in mature individuals is inferred due to habitat degradation and loss as noted in Renjifo et al. (2014) and Freile et al. (2019), although noting that rates of habitat loss appear to have slowed. Given the distribution of suitable habitat and population size, it is not plausible that the largest subpopulation contains fewer than a thousand mature individuals. Therefore the species approaches thresholds for listing as threatened under Criterion C2a(i), and is assessed as Near Threatened.
