Like other waterfowls, ducklings learn to communicate in eggs with one another and attempt to hatch together.

The visual abilities of ducks are exceptional and they can see details at greater distances than humans.

Ducks are able to move each eye independently, and they can store information on both sides of their brains. 

Ducks can have one eye open while they sleep to look out for predators. 

Duckbills have touch receptors that are very sensitive, which makes them similar to our fingertips. 

Because the blood vessels in their feet and legs are so close together, ducks can swim even when it is cold outside. This prevents heat loss. 

The ability of ducklings to understand the relationships between objects is a sign of abstract thought abilities. 

Research suggests that ducks might prefer colors in the blue or green spectrum. 

Like other waterfowls, ducks have up to 12,000 muscles that control their feathers. These muscles can be used to compress or lift feathers, regulate body heat, and show emotion. 

The plumage of female ducklings and ducklings is plain with dark feathers. This pattern forms on their heads and eyes. This helps camouflage their eyes from predators and other ducks. 

Nest parasitism is a practice that many ducks and waterfowl use to lay eggs in the nests or other females of the same species. 

Many times, mallards have eggs that are fertilized by different males. This is believed to increase the chances of successful fertilization and genetic variation. 

The Canadian Wildlife Service found that 40% of first-year hens survived to breed after hatching from ducklings that were born within the first five days. 

Harlequin ducks build their nests in rock crevices near streams. They then dive into the roaring waters to catch invertebrates. They then walk upstream after they are done. 

Although all ducks can learn to dive, some duck species excel at it. The long-tailed duck (also known as an oldsquaw) is the best, and can dive up to 240 feet. 

A 29-year-old canvasback was the oldest duck taken by a hunter. 

The average elevation of ducks is 200-400 feet, but they can reach heights of up to 21,000 feet.

Red-breasted mergansers were the fastest ducks to fly, reaching speeds of over 100 mph. 

This list of fun and fascinating facts about ducks will hopefully give you a fresh perspective on these unique birds and what they can do.
