Summary: Mallard ducks aced Audubon Arctic Wall Calendar 2022 as January birds in Canadian, Mexican, Unitedstatesian February-September breeding or all-year abodes.
Mallard ducks aced Audubon Arctic Wall Calendar 2022 as January birds in coastal Canadian, coastal and inland Unitedstatesian and inland Mexican all-year abodes and inland Canadian, Mexican and Unitedstatesian February-September breeding abodes.
The Anseriformes (from Latin ānser, “goose” and -fōrmis, “-shaped”) order member breeds in ditches, marshes, ponds, prairie potholes and other fresh-, and shallow-watered, natural, open wetlands. The Anatidae (from Latin anas, “duck” and Greek -ειδής, “-like” via Latin -idæ) family member clusters in considerable-numbered, considerable-sized, different- and same-specied, pre- and post-breeding flocks. Mallard ducks, described by Carl Linnaeus (May 23, 1707-Jan. 10, 1778), dwell in ground-covering vegetation among tall bushes and grasses or on buildings, islets and ruins.
Anas platyrhynchos (from Greek πλατύς, “flat, wide” and ῥύγχος, “beak”) sometimes elect old nests of large birds or raised sites such as tree crotches and holes.
Plant debris, grasses and leaves furnish lining fashioned with mallard feathers and pale-centered, pale-tipped brown downy tufts that fit over eggs when mothers-to-be fly after food.

Plant debris, grasses and leaves furnish lining fashioned with mallard feathers and pale-centered, pale-tipped brown downy tufts that fit over eggs when mothers-to-be fly after food.
Mallard eggs and nestlings get 4-inch- (10.16-centimeter-) deep nests with 11- to 12-inch (27.94- to 30.48-centimeter) outside and 6- to 7-inch (15.24- to 17.78-centimeter) inside diameters. Mallard nestlings hatch from 7- to 16- or 10- to 12-egg single-, sometimes second-brooded clutches whose last egg-laying heralds mallard mothers-to-be holding 26- to 29-day incubations. The elliptical to sub-elliptical, short, smooth, 2.28-inch- (58-millimeter-) long, 1.61-inch- (41-millimeter-) wide, waxy eggs impart blue greenness, green whiteness or buff-green, green-tinged or near-blue creamy whiteness.
Mallard ducks as February through September newborns, nestlings and fledglings jubilate their parents journeying as Audubon Arctic Wall Calendar 2022 January birds to family raising-friendly junctions.
Eggs hatching within one month kindles precocial (precocious, from Latin praecox, “early-ripened”) hatchlings and nestlings with black-brown upper-sides, buff-yellow undersides, yellow-sided heads and yellow-fronted, yellow-sided necks.

Mallard hatchlings and nestlings lodge yellow-barred wings; yellow-patched sides to their backs and their rumps; blackened brown-olive bills; and brown-gray legs with brown-gray, three-toed, webbed feet. Mallard duck nestlings move almost immediately with their mothers from their birth nests to nearby waters to master diving and swimming motions before maintaining independent lifestyles. Maximum 29-year life-cycle expectancies necessitate mallard ducklings needing to navigate their dependent nestlingness within 7 to 8 weeks and to number among fledged, independent juvenile mallards.
Mallard ducks occur as Audubon Arctic Wall Calendar 2022 January birds even as they obtain fast-, regular- and shallow-oriented flights as full-fledged birds May through December.
Mallard mating-season palates prioritize crustaceans, earthworms, insects and mollusks even as juvenile and mature mallard ducks otherwise pursue acorns, agricultural crops, aquatic vegetation, bread and seeds.

Mallard mating-season palates prioritize crustaceans, earthworms, insects and mollusks even as juvenile and mature mallard ducks otherwise pursue acorns, agricultural crops, aquatic vegetation, bread and seeds.
Physically and sexually mature female mallard ducks quarter black-patched orange bills; dark caps and eye-lines; brown-yellow backs; mottled-brown bellies; brown underparts; and round-, short-, white-feathered outer-tails. Breeding physiology renders olive-yellow-billed, gray-headed, rusty-under-sided summer males from gray-bodied, chestnut-brown-breasted wintering males with yellowest bills; narrow-, white-collared necks; blue-patched, broad-based wings; and black-curled white tails. Mature mallard ducks secure 19.5- to 26-inch- (50- to 65-centimeter-) long, 1.88- to 3-pound (0.9- to 1.4-kilogram) bodies with 32- to 37-inch (82- to 95-centimeter) wingspans.
Mallard ducks as Audubon Arctic Wall Calendar 2022 January birds transmit high-pitched, whistled courtship calls by quiet, raspy raab-calling males to isolated and serialized quack-calling females.
