[56][57], The mallard inhabits a wide range of habitats and climates, from Arctic tundra to subtropical regions. Rule of Thumb Temperature Chart. Separate pens would be required once the males reach mating age. I put food out for thme regularly. Visual orientation mechanisms that ducks use include the sun, polarized light, stars, and even landmarks. When taking off, the wings of a mallard produce a characteristic faint whistling noise. For a citizen science project I am looking for a clear and easy method to visually [22]:506 More similar to the female mallard in North America are the American black duck (A. rubripes), which is notably darker-hued in both sexes than the mallard,[34] and the mottled duck (A. fulvigula), which is somewhat darker than the female mallard, and with slightly different bare-part colouration and no white edge on the speculum. To get all Blue ducklings, you need a Black drake/duck and a Silver duck/drake. [22]:506 Two months after hatching, the fledgling period has ended, and the duckling is now a juvenile. Duck is the common name for numerous species in the waterfowl family Anatidae which also includes swans and geese.Ducks are divided among several subfamilies in the family Anatidae; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species) but a form taxon, since swans and geese are not considered ducks. and geese during the breeding season, and are frequently driven off by these birds over territorial disputes.

Also, the population size of the mallard is very large. [21] Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimise heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. We tested for variation in duckling growth in relation to (1) body mass at hatch, (2) numbers and biomass of aquatic in- vertebrates, and (3) several measures of ambi- ent air temperature. are also known to kill ducklings and adults on occasion. [18] Haplotypes typical of American mallard relatives and eastern spot-billed ducks can be found in mallards around the Bering Sea. [81], During the breeding season, both male and female mallards can become aggressive, driving off competitors to themselves or their mate by charging at them.

Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. Birds use the axes of polarized light to determine the position of the sun and perform sun compass orientation.
