Justification: 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. |

| Range Description: | This species is widespread throughout south and central America (AOU 1983, Sibley and Monroe 1990, Howell and Webb 1995a). It is resident locally in peninsular Florida (USA), and from Sinaloa and Tamaulipas (Mexico) south through Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama, to Colombia, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, Ecuador, Peru, Bolivia, Argentina, Paraguay and Brazil (Sibley and Monroe 1990). |

| Population: | Although uncommon through most of its range and rare in Florida (del Hoyo et al. 1994), it is fairly common in Mexico and northern Central America (Howell and Webb 1995a), and has a large global population estimated to be c.2,000,000 individuals (Rich et al. 2004). |
| Population Trend: |
Increasing
|
| Habitat and Ecology: | Tolerant of a wide variety of habitats, it is found in swamps, woodland, forest edge and open country, generally avoiding heavily forested areas (AOU 1983, Howell and Webb 1995a). It occurs from sea level to 2,000 m, and rarely as high as 3,000 m (Howell and Webb 1995a). The populations in Florida and Central America appear to be partially migratory (del Hoyo et al. 1994). |
