Ducks are able to adapt and sleep in many different locations. They may sleep on land, huddled in their coops or pens or they can be found sleeping in water. They will even float on the surface of lakes and rivers to conserve body heat and prevent predators from noticing them in the dark.
When a duck is ready to sleep, they will halt all their movements and seem to bob in place. They will then tuck their bill in under their feathers and turn their heads to one side. They will keep their eyes open with half of their brain awake to remain vigilant and on the lookout for predators while the other half gets some shut-eye.
In the wild, mallards sleep in a group setting, often going as far as to line themselves up in a row. The ducks at the end of the row are expected to light sleep and remain alert to any nearby movement so that they can rouse their flock if necessary. They will also share the duties of guarding the group and will rotate out who takes the end spot of their row.
During the day, ducks will be active and moving around a lot as they forage for food in their habitat. They will also eat and groom a great deal to stay healthy. They aren’t the brightest creatures of Mother Nature but they have definitely developed some effective sleep schedules that allow them to survive in their challenging environment.
