Family: Passerellidae (New World sparrows)

Authority: (Audubon, 1829)

Red List Category:

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). 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). The population trend now appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). Therefore, the species has been reassessed as Least Concern.

Population size: 410000 mature individuals

Population trend: increasing

Extent of occurrence (breeding/resident): 2,000,000 km²
