Geese are interesting animals, and they have some weird sleeping habits. They don’t sleep in nests like other birds do, but they will spend the night on water bodies or places near them because they feel safer at nights from predators. Domesticated geese also do the same thing; they will look for a safe place to spend the night.
Whenever geese sleep, they tend to stand up with one leg tucked into their body. This is because they lose a lot of heat through their unfeathered legs, and by tucking one of the legs into their bodies, they conserve heat and stay warm while sleeping. Geese are known to have very good hearing and sight as well, so they will listen for any sounds that might come their way while sleeping in open waters or fields, and this keeps them alert to possible predators coming.
Another reason why they often sleep on water is because predators find it hard to reach them when they are in the water. The freezing cold water will keep them protected while they are asleep, and even if predators try to swim to them, they will be alerted by the vibrations of the water on their feathers.
Geese rarely sleep in their nests, but they will use them if they are incubating their eggs. They will also only sleep in their nests during the breeding season and while they are raising their young. However, they will abandon the nest once their goslings are mature enough to fend for themselves.
