Mallards, the ancestor of almost all breeds of domestic ducks, are the most recognized and widely distributed waterfowl in the world. Occupying fresh and brackish waters, especially in wetlands, they also utilize agricultural fields near water as habitat . They are dabbling ducks which means they do not dive underwater for food but feed at or just below the surface, upending in shallow water to get at morsels in the mud bottom .

These birds require shallow water habitats for feeding such as streams , ponds , lakes , marshes, swamps , wetlands, and flooded fields . The water can be fresh or brackish . Although not a preferred habitat, these birds are seen in saltwater marinas but not in the open ocean. They also need dry land for nesting and resting. In Southern California they can occasionally be found nesting in urban gardens under shrubbery.
Vegetation: freshwater lakes and ponds, freshwater marshes • Maximum Elevation: 1,000 meters • Foraging Strata: Water • Center of Abundance: Lower subtropical: lowlands, lower than 500 m.; subtropics. • Sensitivity to Disturbance: Low
Typically found at an altitude of 0 to 3,215 meters (0 to 10,548 feet).
Behaviour In temperate regions
breeding populations of this species
or dispersive, often making local movements during
severe weather5. Other populations are fully migratory2
with females and juveniles
leaving the breeding grounds
in the western
from Septemberand returning as early as February5.
The species breeds between March and June3 in single
pairs or loose
groups1 although the exact timing
varies with latitude3. While the females are incubating4
(from mid-May)5, 6 the males gather3
in small flocks and migrate to moulting areas6
where they undergo a flightless moulting period lasting for c.4 weeks5
(females moult near the breeding grounds)6. Outside
of the breeding season
the species can be found in small to very
large flocks3 numbering up to several hundreds
or even thousands of individuals7 especially when
moulting5, on migration7 and
during the winter2. The species may also roost
both nocturnally and diurnally in communal
groups when not breeding8.
Habitat The species occurs in almost every wetland type1
although it generally avoids fast-flowing, oligotrophic1,
5, 7, deep, exposed, rough, rockbound waters and hard unvegetated
areas such as rocky ground
dunes and artificial surfacing7.
It requires water less than 1 m
deep for foraging7
and shows a preference for freshwater
although it may frequent shallow brackish waters as long as they
provide the cover1, 5 of submerged, floating, emergent
vegetation, dense reedbeds or overhanging branches7.
commonly frequented include flooded swampy woodlands, seasonal
floodlands7, wet grassy swamps
and meadows, oxbow
lakes6, open waters
, banks or spits
waters1, 5, 7,
canals and sewage
farms7. During the winter the
species may also be found in saline habitats along the coast3
where water is shallow, fairly sheltered and within site of land7
lagoons7, brackish estuaries1,
7 and bays1). Diet The species
and opportunistic1, 7, feeding by
in water and by grazing on the land7.
consists of seeds and the vegetative
parts of aquatic
)1, as well as terrestrial
and aquatic invertebrates (especially in the spring
and summer) such
as insects, molluscs
, crustaceans, worms and occasionally amphibians
and fish1. Breeding site The nest
is a shallow
depression7 or bowl
of vegetation that can be situated
in many different locations such as within vegetation on the ground,
in natural tree
cavities1 up to 10 m high (Africa)8,
under fallen dead wood
, on tree stumps6, under
bushes8 and even in abandoned nests of other species
(e.g. herons or crows)6. Nests are generally placed
close to water2 although occasionally they may
be some distance
"Extensive" grazing of wetland grasslands (c.0.5 cows
was found to attract a higher abundance
of the species in Hungary19.
Studies in Danish coastal wetlands found that the spatial restriction
of shore-based shooting was more successful at maintaining waterfowl
population sizes than was the temporal
restriction of shooting, and
therefore that wildfowl reserves should incorporate shooting-free
refuges that include adjacent
marshland in order
to ensure high waterfowl
species diversity20. The cyclical removal of adult
fish from an artificial waterbody
) in the UK resulted
in an increase in invertebrate
food availability and an increase
in the growth of submerged aquatic macrophytes, which in turn
to an increased use of the habitat for brood rearing
by the species26.
The removed fish (dead or alive) were sold to generate funds26.
The species will also nest in artificial nest boxes1, 8

of mallards consists mainly of vegetation (floating, submerged,
and emergent), but also includes aquatic
such as worms,
mollusks, and arthropods
. They eat seeds of wild rice, pond- weeds
water elm, and oaks, and visit agricultural stubble fields
on leftover grain. They also eat people food fed to them by humans
in parks, at lakes
This is usually bread which is not good
Mallards have several eating strategies. They feed at the water’s surface by straining water through their bill, upend in shallow water to reach deeper food items either below the surface such as submerged plants or in the mud such as snails. Walking on land , they pick up food with the nail of their bill or strip seed heads and foliage with the bill's edge .
