Description

Physical Description

Adult Female: Face : Cheeks: faint line below eye Bill: blackish gray Neck: Throat : lighter brown.Adult Male: Head : Cap: blackish Color: black Face: Cheeks: white Bill: blue Body: Belly: whitish with light brown barring Color: dark chestnut Tail: black Length : long.

Color:

Adult male alternate: Alternate plumage worn in Spring and Summer · Brilliant blue bill · Black crown and nape · Rust-red lower neck, breast, back and body · White face · Black tail

Adult male basic(eclipse): Eclipse plumage worn Fall-Winter · Dark gray bill · Dark cap · Face white, as in alternate plumage · Gray brown neck and body plumage

Adult female: Like winter male, but with dusky horizontal stripe crossing pale gray cheek patch

Size/Age/Growth

About 14 to 16 inches long, with a wingspan of 21 to 24 inches. Adults weigh about 20.8 ounces . Weight : female 550g, male 600g.

Habitat

Marshes, lakes and coastal areas; when not breeding, on sheltered brackish and marine coastal areas as well as lakes and rivers (Temperate Zone). Nests on freshwater marshes, sloughs , lakes, and ponds , in areas where open water is bordered by dense aquatic vegetation. Nest is a floating structure of marsh plants hidden by growing plants. Often lays eggs in nests of other waterfowl species. May nest at potholes of less than an acre (InfoNatura, 2004).

Vegetation: freshwater lakes and ponds • Maximum Elevation: 2,200 meters • Foraging Strata: Water • Center of Abundance: Lower tropical: lowlands, lower than 500 m.; tropics. • Sensitivity to Disturbance: Medium

Typically found at an altitude of 0 to 4,701 meters (0 to 15,423 feet).[1]

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).[2].

Diet

Mostly: Green Plant Matter Seeds. Lesser Quantities of: Aquatic Invertebrates .

Reproduction

Seasonal - from April to August. Timing of breeding controlled by physiological readiness modified by food availability, stability of water levels and available nesting cover . Egg-laying season aligned symmetrically either side of longest day. May dump eggs and forego breeding if conditions unsuitable. Breeding strategy mixture of monogamy, polygyny and promiscuity .2-3 young per female per year. Can relay up to 4 times per season if eggs lost. Usually only one brood per year, but can double brood.

Produces large eggs to maximise survival of large nidifugous young. Also lays eggs in the nests of other waterbirds. Breed first at one year old. Young creche after females desert chicks at only half grown. Arrive on breeding grounds in April, nest building mainly in May, incubation in June, most broods hatch in July. Birds leave breeding areas in August/September. In USA, age composition in autumn estimated at 1:1 adults :juveniles. Sex ratio male biased (c1 .1-1-2 males per female in late winter). Survival rates unknown, but simulation modelling for UK population assuming adult male, adult female and juvenile survival rates of 0.8, 0.7 and 0.6, respectively, produced observed population trend. Maximum lifespan of wild ringed individuals in USA 13 years, but most reported dead less than 2 years after ringing (US Dept. Interior unpubl. data ); 18 captive birds had mean lifespan of 2.4 years.
