Mallard Ducklings
Anas platyrhynchos
33.1517, -97.0163
Field Notes
Description:
Mallard pairs form long before the spring breeding season. Pairing takes place in the fall, but courtship can be seen all winter. Only the female incubates the eggs and takes care of the ducklings. The female forms a shallow depression or bowl on the ground in moist earth. She does not carry material to the nest but rather pulls vegetation she can reach toward her while sitting on nest. During egg-laying phase, she lines the nest with grasses, leaves, and twigs from nearby. She also pulls tall vegetation over to conceal herself and her nest. After incubation begins, she plucks down feathers from her breast to line the nest and cover her eggs. The finished nest is about a foot across, with a bowl for the eggs that is 1–6 inches deep and 6–9 inches across.
Habitat:
Lake Lewisville
Notes:
Mallards are large ducks with hefty bodies, rounded heads, and wide, flat bills. Like many “dabbling ducks” the body is long and the tail rides high out of the water, giving a blunt shape. In flight their wings are broad and set back toward the rear. Male Mallards have a dark, iridescent-green head and bright yellow bill. The gray body is sandwiched between a brown breast and black rear. Females and juveniles are mottled brown with orange-and-brown bills. Both sexes have a white-bordered, blue “speculum” patch in the wing.
