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 extremely 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.
Partners in Flight estimate the total population to number 5,000,000-50,000,000 individuals (A. Panjabi in litt. 2008).
The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007).
Pyrocephalus rubinus occurs throughout much of the Neotropics, with a range covering south-west U.S.A., Mexico, Belize, Guatemala, Honduras, Nicaragua, Colombia, Venezuela, Guyana, Brazil, Colombia, Ecuador, Peru, Chile, Bolivia, Paraguay, Argentina and Uruguay (del Hoyo et al. 2004).
