Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor/s: BirdLife International
Reviewer/s: Butchart, S. & Symes, A.
Facilitator/s: Ekstrom, J., Butchart, S., Temple, H.
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). 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 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). For these reasons the species is evaluated as Least Concern.

Population: (Wetlands International 2006)
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species is partly migratory; North American breeders tend to depart from breeding grounds to winter further south or near the coast, whereas other populations are sedentary or make only short-distance movements. Freshwater swamps, lakes, pools, and marshes with emergent vegetation and open water are preferred breeding habitats, although outside the breeding season the species can also be found on larger lakes, brackish lagoons and estuaries (Carboneras 1992).
Systems: Terrestrial; Freshwater
