[99] They are a common sight in urban parks, lakes, ponds, and other human-made water features in the regions they inhabit, and are often tolerated or encouraged in human habitat due to their placid nature towards humans and their beautiful and iridescent colours. and geese during the breeding season, and are frequently driven off by these birds over territorial disputes. Mallards are thought to be the most common duck on the planet. [20], The size of the mallard varies clinally; for example, birds from Greenland, though larger, have smaller bills, paler plumage, and stockier bodies than birds further south and are sometimes classified as a separate subspecies, the Greenland mallard (A. p. are also known to kill ducklings and adults on occasion. This is because it has a large range–more than 20,000,000 km2 (7,700,000 mi2)[97]–and because its population is increasing, rather than declining by 30% over ten years or three generations and thus is not warranted a vulnerable rating. [27] Upon hatching, the plumage of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the back (with some yellow spots) all the way to the top and back of the head. [77][79] The ducklings are precocial and fully capable of swimming as soon as they hatch. Blue is incompletely dominant. Two blue genes produces silver.

Having multiple males in your backyard flock will cause your adult males to fight endlessly if there are females around to compete over. The most important time in a duckling's life is the first two weeks of life. We try to peak in production for the Easter hatch, it takes about nine weeks from the first egg to maximum egg production and we want them about 22-23 weeks of age at first egg. [28] As it nears a month in age, the duckling's plumage starts becoming drab, looking more like the female, though more streaked, and its legs lose their dark grey colouring. Ducks that feed on seeds or waste grain must also leave the area when snow falls cover their foods. To keep ducklings healthy a hen must brood or keep ducklings warm until they can do it themselves, help ducklings find a good source of food, ensure family bonding as a unit and finally, guide young ducks during migration and help them locate staging and wintering habitat.

During the migrations, they will usually stop at places where they have been before. She sits very tightly, and her brown plumage blends her perfectly to the background. The loons, meanwhile, dote on it with fresh fish. [112], Mallards are causing severe "genetic pollution" to South Africa's biodiversity by breeding with endemic ducks[113] even though the Agreement on the Conservation of African-Eurasian Migratory Waterbirds – an agreement to protect the local waterfowl populations – applies to the mallard as well as other ducks. I put food out for thme regularly. For a citizen science project I am looking for a clear and easy method to visually If a Blue drake and Blue female duck breed, you get black, silver and blue ducklings. [134] Usually, only the breast and thigh meat is eaten. One blue gene with black produces blue. [94] Also, mallards may be attacked by larger anseriformes such as swans (Cygnus spp.) 1985). ... Rule of Thumb Temperature Chart. Scientist speculate that the reason for there being more drake (male) mallards than female's (hens) in the population is the result of the higher deaths that occur to hens during the post breeding period. [120][1] Mallards sometimes arrive on its island home during migration, and can be expected to occasionally have remained and hybridised with Laysan ducks as long as these species have existed. The Rouen ducklings can also be distinguished from wild Mallard ducklings by the presence of a second stripe which runs across their face, just under their eyes. Habitat of the Mallard. They have a wingspan that ranges from 32 to 39 inches. [83] Males tend to fight more than females, and attack each other by repeatedly pecking at their rival's chest, ripping out feathers and even skin on rare occasions. They range in size from 20 to 26 inches long. Every summer we hatch a large flock of duck breeders for the next year's egg production. [87], Mallards are opportunistically targeted by brood parasites, occasionally having eggs laid in their nests by redheads, ruddy ducks, lesser scaup, gadwalls, northern shovellers, northern pintails, cinnamon teal, common goldeneyes, and other mallards. Mute swans (Cygnus olor) have been known to attack or even kill mallards if they feel that the ducks pose a threat to their offspring. Gallery of mallard duck photos, including different genders, ages, and habitats, with identification tips and trivia about mallards.
