Coming from the same family as swans and geese, ducks are found on every continent except Antarctica.
What is the weight of a duck?
Their weight very much depends on the type of duck.
On average, an adult mallard will weigh between 1.6 to 3.5 pounds (0.72 to 1.6 kg).
Meanwhile, a pintail will weigh between 1 to 3.1 pounds (0.45 to 1.4 kg).
An adult gadwall or “Alabama Mallard” will weigh approximately 1.1 to 2.2 pounds (0.5 to 1).
Ducks are a member of the Anatidae family, which also includes geese and swans.
An adult male is called a drake, while females are known as hens.
Baby ducks are called ducklings. A mother hen may lead her ducklings over half a mile in search of water for swimming and feeding.
Ducks have waterproof feathers that interlock and have a waxy coating. The downy underlay stays completely dry even while diving underwater!
There are at least 38 types of ducks living in the US, with nearly all of them being decedents of the mallard.
~ Fun Fact ~
The feet of a duck never get cold! Since ducks have no blood vessels or nerves in their feet, they never get cold on ice or in freezing water.
