7 thoughts on “Grey-capped Tyrannulet (Phyllomyias griseocapilla)”
The forests inhabited by this species at the southern edge of its range, in the highlands of northeastern Rio Grande do Sul state, Brazil, are not currently under immediate threat. However, the species is scarce and localized within the state, with fewer than 20 records known in total. While climate change may impact these forests over the long term, there is no indication that this will pose a significant threat within the timeframes defined by the IUCN criteria. Based on my fiel experience with this species, I fully agree with the new category proposed.
The species is common in the mountains of eastern Bahia (higher altitude areas). It could potentially be a species sensitive to climate change in the future, but at the moment I agree that its situation is of little concern.
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.
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.
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.
The national assessment also considered the species LC:
Phyllomyias griseocapilla is endemic to Brazil and occurs from Bahia to Rio Grande do Sul. It inhabits humid subtropical forests and forest edges, and although its population is fragmented, the species is relatively common in certain areas, especially at higher altitudes. Its main threat is habitat loss due to the expansion of agriculture, mining, and urbanization. However, considering its wide distribution and its ability to occupy secondary forests, these threats do not appear to be sufficient to push it to one of the extinction risk thresholds in the near future. Therefore, P. griseocapilla was categorized as Least Concern (LC).

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Grey-capped Tyrannulet is recommended to be listed as Least Concern.
