GENERAL DISTRIBUTION : 
In North America the gadwall's breeding range extends from southern
Alaska and southern Yukon to the New Brunswick-Nova Scotia border, south
locally to southern California, northern Texas, central Minnesota, and
northern Pennsylvania, and along the Atlantic Coast south to Florida and
the Gulf Coast [6,19].  It also breeds in Iceland, the British Isles,
Europe, and Asia [6].

In North America the gadwall winters from coastal Alaska south to

PLANT COMMUNITIES : 
During the breeding season, gadwalls often inhabit islands in wetland
communities with patches of dense western snowberry (Symphoricarpos
occidentalis), slim nettle (Urtica gracilis), Canada thistle (Cirsium
arvense), rose (Rosa spp.), and brome (Bromus spp.).  Additionally,
gadwalls commonly use areas dominated by cattail (Typha spp.), bulrush
(Scirpus spp.), sedge (Carex spp.), and common rivergrass (Scolochloa
festucacea) [8].  Gadwalls will also use upland cover types of cropland,
pasture and hayland, grassland, and mixed prairie and weed [8,9,16].
