7 thoughts on “Alta Floresta Antpitta (Hylopezus whittakeri)”
The last national assessment was carried out in 2017. In that year, habitat loss was estimated between 40 and 50%, and the species is categorized as VU. This species will be reassessed by Brazil in the second half of 2026, updating habitat loss data according to the method proposed by Butti et al. (2022) and MapBiomas (https://mapbiomas.org/).
Unclear if this species or paraensis occurs in the Rio Iriri mini-interfluve but that will affect mapping output. It is sensitive to forest fragmentation as noted (Lees & Peres 2010) but also sensitive to forest degradation. Across a sample of 74 primary forest transects sampled in and around around the Tapajós National Forest we found the species at 9 sites, 29% of undisturbed sites (n=17), 4% sites that had been logged only (n=25), 22% of sites which had been burned only (n=9) and 4% of logged and burned sites (n=23) and at none of 24 variably-aged secondary forest sites (see Moura et al. 2013).

Última avaliação Brasil, realizada em 2017, foi categorização como Vulnerável (VU) pelo critério A2c. Cálculos realizados sobre perda de qualidade de habitat devido queimadas e corte seletivo estimam perda entre 30-50% para área de distribuição da espécie (Barlow et al., 2016).
Realizei uma análise da perda de habitat por sensoriamento remoto utilizando o método proposto por Butti et al. (2022), que utiliza ferramentas de sensoriamento remoto disponíveis no Google Earth Engine (https://earthengine.google.com/) e na plataforma MapBiomas (https://mapbiomas.org/), no período entre 2011 e 2024 (três gerações), indicam uma perda de habitat de 7% em áreas classificadas como “Formação Florestal” dentro do polígono de distribuição da espécie.
Assim como seu congênere (Hylopezus paraenses), considerando a especificidade ecológica da espécie, sua forte dependência de florestas bem conservadas e sua elevada sensibilidade a alterações no habitat, é razoável assumir que a perda de habitat — especialmente quando considerados os impactos adicionais da degradação associada aos incêndios florestais e corte seletivo, que não são plenamente captados por métricas baseadas exclusivamente em sensoriamento remoto da cobertura vegetal — afete a espécie de forma desproporcional.
Dessa forma, é plausível suspeitar uma redução populacional de, no mínimo, 30% ao longo das últimas três gerações do táxon (13 anos).
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 2 February 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 2 February 2026, when discussions will re-open.
We thank all contributors for their comments. All relevant information will be incorporated into the updated Red List assessment for this species.
This species is highly forest-dependent and is expected to be disproportionately affected by forest loss, especially when considering additional impacts of degradation. However, it is difficult to justify that the rate of decline exceeds 30% in a three-generation period (c. 13 years) based on ongoing rates of habitat loss. Within the species’ mapped range, Global Forest Watch (2026) indicates that habitat loss has been equivalent to c. 9% in the last three-generation period, and MapBiomas (2026) indicates a loss of c. 7%. It is considered plausible that declines have exceeded 20% over the past three generations, and the rate of reduction is here suspected to fall within the range 10-25%, but a decline exceeding 30% appears unlikely. However, further input on this is welcome.
Based on available information, our preliminary proposal for the 2026 Red List would be to adopt the proposed classification outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 8 February 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 later this year, 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. Alta Floresta Antpitta is recommended to be listed as Near Threatened, approaching thresholds under Criteria A2c+4c.
