mallard (Anas platyrhynchos)
CONFIRMATION STATUS: Confirmed.
Length: 15-16 inches Wingspan: 36 inches
Large dabbling duck
Blue speculum with white bar along both leading and trailing edges
Silvery-white wing linings
Juvenile similar to adult female
In the southwestern United States the "Mexican Duck", formerly a separate species, has both sexes similar to the female mallard
Adult male alternate:
Alternate plumage worn from fall through early summer
White ring around neck
Gray flanks and upperwing coverts
Black undertail coverts contrast with white tail
Adult male basic:
Similar to adult female, but usually with chestnut breast and an unmarked yellowish bill
Orange bill with black central patch
Pale brown face
Dark cap and eye line
Mottled brown and tan plumage
Adult male in alternate plumage is unmistakable. Females, immature and
eclipse-plumage males could be confused with black ducks, gadwalls and
mottled ducks, but note the blue speculum with white borders on both
sides. Gadwalls are also distinctive in their steeper forehead, gray bill
with orange edges and white belly patch. Hybrid mallard x black ducks
are often seen and are darker than mallards, with a more purple speculum
bordered by white on one or both edges and usually show some traces of
the mallard plumage.
