LC
Amazonian Grosbeak Cyanoloxia rothschildii



Justification

Justification of Red List category
This species has an extremely 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 is very large, and hence does not 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
Prior to being split from Cyanoloxia cyanoides, Partners in Flight estimate the total population to number 500,000-4,999,999 individuals (A. Panjabi in litt. 2008).

Trend justification
Prior to being split from Cyanoloxia cyanoides, this species was suspected to lose 15-16.9% of suitable habitat within its distribution over three generations (13 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
