Ducks can live 5 to 8 years.
Ducks are smaller, have shorter feathers and have limited flight distances. All ducks, which reach sexual maturity within the first year, mate only during the breeding season, unlike swans and geese, which mature later and mate for life. Based on ducks' unique behaviors, ducks can be divided into three main groups: teal ducks, diving ducks, and perching ducks.
The mallard is a typical teal duck and the ancestor of most domestic ducks. Perching ducks like the Moscow duck have long claws and are the most arboreal of ducks. The largest number of diving duck species (including sea ducks) is found here. Mallards fly from south to north to lay eggs in the spring, then south to overwinter in the fall. After having beendomesticated by humans, they lost their ability to fly. A duck's eyes have a 360-degree field of vision, allowing it to see behind itself without turning its head.

Population distribution:
1. Teal
The mallard (a typical teal) is the ancestor of most domestic ducks (see Poultry [Poultry]) and is one of the most popular game birds. Mallards fly from south to north to lay eggs in the spring, then south to overwinter in the fall.
After being domesticated by humans, they lost their ability to fly. In order to get more duck eggs, people didn't let them stop producing duck eggs. Over time, domestic ducks lose the ability to hatch their eggs. Distributed worldwide, mainly in inland waters, common in temperate regionsare from the northern hemisphere.
2. Diving Ducks
Diving ducks include the more marine species, such as eider ducks and Muscovy ducks; they also include the merganser family (most of which like to live in freshwater areas, see Merganser flocks). Growing up in Australia.
3. Perching Ducks
Perching ducks such as Moscow ducks have long claws and are ducks that like to live in trees. The hard-tailed duck family (see article on Stifftail), with the ruddy duck as a typical example, is very aquatic and is characterized by its legs located immediately behind the body. Whistling ducks (also known as tree ducks) are not true ducks, but are more closely related to geese and swans. This tribe is widespread, especially in the tropics.
