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): Ekstrom, J., Butchart, S., Harding, M., Fisher, S.
Justification:
Although this species may have a restricted range, it is not believed to 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.

Geographic Range [top]

Range Description: This species was rediscovered in 1992 (161 years after the collection of the type-specimen) in campina forest on the east bank of the rio Negro, c.45 km north of Manaus, Brazil, extending its range by c.1,000 km east-south-east of the rio Içana type-locality (Whittaker 1995). It has subsequently been found in several other areas further up the rio Negro on two right-bank tributaries, the rio Apuaú and rio Cuieras, c.80 km north-west and 60 km west of the 1992 records (Whittaker 1995), and appears to be relatively common in white-sand and igapó forests on the east bank of the rio Negro (M. Cohn-Haft in litt. 1999).
