|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Butchart, S. & Symes, A.|
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:||(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|
|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|
|Major Threat(s):||Habitat alteration, especially removal of forest, is thought to affect some populations.|
