5 thoughts on “Fringe-backed Fire-eye (Pyriglena atra)”
This Brazilian endemic species was assessed as EN on the National Red List assessment. The text from the ICMBio’s online platform SALVE reads:
“Pyriglena atra é endêmica do Brasil, restrita ao Sergipe e nordeste da Bahia. É dependente sub-bosques de florestas perenes de baixada. Sua área de ocupação (AOO) foi calculada em 108 km². A população encontra-se severamente fragmentada e seu habitat está ameaçado pela silvicultura e expansão imobiliária. Dessa forma, P. atra foi avaliada como Em Perigo (EN) B2ab(i,ii,iii).”
Extensive fieldwork has been done by Sidnei Sampaio at the Federal University of Bahia to survey this species within its range, the results of which are as yet unpublished, but would help to clarify its status. I have requested more information from Sidnei but not received it in time to comment here. I suggest pending this decision as his data may help to answer some of the specific questions raised.
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 25 April 2025. 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 25 April 2025, when discussions will re-open.
We thank all contributors for their comments. While calculating AOO solely based on a grid over validated georeferenced records may yield a value that falls below threatened thresholds, this does not account for the potential occupancy of remaining apparently suitable habitat and is thus likely to result in a significant underestimate.
The AOO for this species is unknown, but if it did fall below the threshold for Vulnerable (2,000 km2), it would still need to meet two of the additional subcriteria to qualify as Vulnerable. Specifically, in addition to the ongoing decline in habitat area/extent/quality, it must either be severely fragmented (>50% of individuals or the total AOO in habitat patches that are both isolated and too small to support viable populations) or be restricted to ten or fewer locations (the term ‘location’ defining a geographically or ecologically distinct area in which a single threatening event can rapidly affect all individuals of the taxon present). There is currently no evidence that the majority of individuals are in subpopulations that would be considered unviable. The spatial footprint of each individual threat event likely to affect the species is small, such that the number of locations would be many.
This species has been assessed based on available information at the time of assessment. Given the species meets the EOO threshold and there is ongoing forest loss within the range, it approaches, but does not meet, the required thresholds for listing under Criterion B. We urge contributors to share any information that may affect the value of the key parameters in Annex 1 however, and thus potentially affect the reassessment.
Based on available information, our preliminary proposal for the 2025 Red List would be to adopt the proposed classification outlined in the initial forum discussion. Further input is sought, particularly regarding the specific questions outlined in the proposal above. Is there any information, even if speculative, regarding the population size or density of this species?
There is now a period for further comments until the final deadline on 4 May 2025, after which the recommended categorisations will be put forward to IUCN.
The final 2025 Red List categories will be published on the BirdLife and IUCN websites in October 2025, 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. Fringe-backed Fire-eye is recommended to be listed as Near Threatened, approaching thresholds under Criterion B1b(iii).
