Taxonomic Comments
Formerly (AOU 1983, 1998) considered part of Anas, but now treated as separate on the basis of genetic data (Gonzalez et al. 2009) which indicate that Anas as previously constituted was paraphyletic, and further that it consisted of four deeply divergent clades, now recognized as the separate genera Sibirionetta, Spatula, Mareca, and Anas (cf. Livezey 1991). Linear sequence of genera and species follows Gonzalez et al. (2009). (AOU 2017).

Range Extent Comments
BREEDING: Holarctic. In North America, primarily from Alaska east to Manitoba, south to California, New Mexico, Nebraska, western Iowa, locally eastward; also in Eurasia. NON-BREEDING: southwestern British Columbia, Arizona, east to Gulf Coast, coastal Georgia and South Carolina south to northern Colombia (rarely northern Venezuela), West Indies, and Hawaii, rarely north to north-central and northeastern U.S.; also Old World. In the U.S., the highest winter densities occur in the San Joaquin and Imperial valleys and the Clear Lake refuge in California, and the Bitter Lake refuge in New Mexico; winter abundance may vary greatly from year to year at a particular location (Root 1988).
Ecology & Habitat

Habitat

BREEDING: Shallow, often muddy, fresh-water areas with surrounding cover. Ponds, marshes, sloughs, and creeks. Nests near shallow freshwater lake, pond, marsh, etc. Nests on the ground, usually near edge of water. The nest is a hollow lined with plant material and down. NON-BREEDING: In migration and winter in both freshwater and brackish habitats, and in cultivated fields (not typical) (AOU 1983).

Ecology

Large concentrations seen at migration staging areas. Usually feeds in pairs or small groups.

Reproduction

Breeding begins in late March in the south to early June in the north. Clutch size: 6-14 (usually 10-12). Incubation: 23-25 days, by female (Terres 1980). Young are tended by female, independent in about 6-7 weeks (Harrison 1978). Clutch size may be limited by lipid reserves rather than by protein acquisition (Ankney and Afteon 1988).
