7 thoughts on “White-browed Antpitta (Hylopezus ochroleucus): Revise global status?”
I’m not aware of any detailed studies that would provide the quantitative information requested. Although it is not a common species, it is widely observed throughout the Caatinga (see map: https://www.wikiaves.com.br/wiki/pompeu) and therefore it seems reasonable to assume a reasonably large population.
This species is LC on the Brazilian National Red List, and as a Brazilian endemic, the proposal to downlist as LC globally would bring the two lists into synchrony. For these reasons, I support the proposal.
In the assessment of the risk of extinction of Brazilian fauna carried out in 2017, the species was categorized as Least Concern (LC).
*Evaluators:* Helder Farias Pereira de Araújo; Antonio Emanuel Barreto Alves de Sousa; Caio Graco Machado Santos; Diego Mendes Lima; Fabio de Paiva Nunes; Juan Manuel Ruiz spars Aguilar; Leonardo Fernandes France; Márcio Amorim Efe; Marcos Pérsio Dantas Santos; Rachel Maria de Lyra Neves; Weber Andrade de Girao e Silva
*Criterion A* – In the assessment carried out in 2017, we did not find long-term data from population estimates to track the decline by observed data (a) and the decline of AOO and EOO (c) do not reach the thresholds for a threat category. Habitat loss calculations do not reach quantitative thresholds for generational time.
*Criterion B* – The EOO calculations (708,613 km2) do not meet the thresholds for categorizing threatened. Its AOO (2,895 km2), calculated by superimposing a grid with 4 km2 squares to the confirmed, inferred and suspected current record points, does not reach the quantitative threshold and does not meet the sub-criteria.
*criterion C* – There is no information available on population estimates.
Criterion D – There is no information available on population estimates.
Criterion E – in the evaluation carried out in 2017, we did not find PVA data.
JUSTIFICATION: Hylopezus ochroleucus is endemic to Brazil, occurring in the interior of the Northeast and North of Minas Gerais. It occupies deciduous and semideciduous forests, rich in lianas and with a well-developed understory. In the Caatinga, it is strongly associated with forest formations (semi-deciduous forests, vine forests, arboreal caatinga and shrubby caatinga). In the Caatinga, the type of vegetation occupied by the species is related to very fertile soils and great timber potential, being a preferential target for deforestation both for agricultural expansion and for the supply of wood for firewood and furniture making. Although habitat loss and fragmentation represent an impact, there is no risk of extinction in the near future for the species. Therefore, H. ochroleucus was categorized as Least Concern (LC).
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 18 July 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’ Red List status on this page on 18 July 2022, when discussions will re-open.
Based on available information, our preliminary proposal for the 2022.2 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 24 July 2022, after which the recommended categorisations will be put forward to IUCN. The final 2022.2 Red List categories will be published on the BirdLife and IUCN websites in December 2022, 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. White-browed Antpitta is recommended to be listed as Least Concern.

I agree with the downlist, LC seems more appropriate than NT for this species.
