Mallards measure 16 to 24 inches at maturity. The head
and neck of the male is glossy green, with a white ring. The
female is brown overall with a blue speculum band on the wing.
The bill is yellow or orange. The preferred habitat of mallard
is shallow ponds, marshes or sheltered salt water in the winter.
Mallard commonly put down on any pond where domestic ducks are
known to habit.
The most common duck in the world breeds in Europe, Asia
and North America. Remarkably adaptable to civilization, it will
breed in a city park if there is even a small pond. Mallards
usually nest near the water's edge, but occasionally they choose
a site on higher ground. When the ducks are agitated, they can
leap upward from the water into flight and then almost hover
in mid-air before selecting an escape route. Mallards are often
seen with just the ends of their tails sticking up out of shallow
water as they feed on plants and small animals found at the bottom.
They also eat grain and other foods.'s
