Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Harding, M., Ekstrom, J., Butchart, S.
Justification:
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.

Geographic Range [top]

Range Description: This species was thought to be endemic to xeric caatinga of north-east Brazil but a population was recently discovered in east-central Brazil (Cleere and Nurney 1998, Ribon 1995, Vasconcelos and Lins 1999). There are three races: the nominate from south Piauí, south-east across Bahia and east to Alagoas; cearae from Ceará south through east Piauí to extreme north Bahia; and the newly described vielliardi from Colatina, Espírito Santo (Cleere and Nurney 1998) and Aimorés, Minas Gerais (Vasconcelos and Lins 1999).

Population [top]

Population: The global population size has not been quantified, but the species is described as poorly known and probably not very common (Cleere 1998).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species largely prefers lowland deciduous forest especially with open sandy areas (Stattersfield et al. 1998), although the newly described subspecies vielliardi occurs in rocky areas (Cleere and Nurney 1998).
Systems: Terrestrial

Threats [top]

Major Threat(s): Caatinga habitats have suffered markedly from agricultural expansion, grazing and burning since the late 18th century (Stattersfield et al. 1998). The level of general disturbance has further increased in the last 30 years since the arrival in the area of the Brazilian oil company, Petrobrás, which has improved access, permitting an influx of settlers and relocation of many families by government agencies (Hart 1991, Stattersfield et al. 1998).
