Data Zone
Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but density descriptions range from locally uncommon to fairly common (Stotz et al. 1996, Clock 2020, Silveira et al. 2023).
Trend justification
A slow population decline is suspected owing to habitat loss and fragmentation. Tree cover within the range is lost at a rate of 6% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is restricted to forests and mature secondary growth, it shows some tolerance of habitat disturbance (Silveira et al. 2023). Population declines are therefore likely slow and localised; they are here tentatively placed in the band 1-9% over ten years.
Hemitriccus orbitatus is endemic to south-east Brazil.
It is resident in the lower and middle growth of lowland evergreen forest and mature secondary woodland (Ridgely and Tudor 1994).
Current key threats are urbanisation, industrialisation, agricultural expansion, mining, colonisation and associated road-building (Dinerstein et al. 1995, Silveira et al. 2023). However, the species can be found in secondary forests and is tolerant to certain environmental changes (Silveria et al. 2023).
Conservation Actions Underway
It occurs in a number of protected areas, including Aparados da Serra, Serra da Bocaina, Serra do Itajaí, Serra dos Órgãos, Serra Geral, Tijuca, Itatiaia, Caparaó and Saint-Hilaire/Lange National Parks.
Conservation Actions Proposed
Quantify the population size. Research its ecology and ability to persist in degraded and fragmented habitats. Monitor the population trend. Protect areas of suitable habitat within the range.
