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). The population trend appears to be stable, and hence the species does not 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.
The global population size has not been quantified, but this species is described as 'rare to uncommon' (Stotz et al. 1996).
Population trends have not been quantified, although extensive deforestation east of the rio Tocantins, including within protected areas (M. and P. Isler in litt. 1999, Stotz et al. 1996), and understorey degradation may be adversely affecting this poorly known species.
This species occurs east of the rio Tocantins in north Brazil, in Pará, Ceará (where it may persist only in Gorupi reserve), Maranhão and Piauí.
The species inhabits lowland humid forest and is very common in mature second growth in east Pará (Ridgely and Tudor 1994).
Extensive deforestation east of the rio Tocantins, including within protected areas (Stotz et al. 1996, M. and P. Isler in litt. 1999), and understorey degradation may be adversely affecting this poorly known species. However, it persists in small woodlots east of São Luís, Maranhão, but it presumably cannot disperse between isolated woodlots and such fragmentation probably has long-term consequences (Collar and Andrew 1988).
