Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016

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 trend 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). 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.

Population [top]

Population:(Rich et al. 2004)

Trend Justification:  This species has undergone a large and statistically significant increase over the last 40 years in North America (226% increase over 40 years, equating to a 34.3% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Note, however, that these surveys cover less than 50% of the species's range in North America.
Current Population Trend:Increasing
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:The species inhabits a wide variety of habitats, depending on the region, including boreal coniferous forests, temperate deciduous woodland, tropical and subtropical cloud forest, gallery forest and semi-open savanna woodland, from sea level to 2,700 m. Outside the breeding season, North American birds can be found in almost any terrain, including urban areas with trees.
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):7.2
Movement patterns:Full Migrant

Threats [top]

Major Threat(s): Habitat alteration, especially removal of forest, is thought to affect some populations.
