Many animals sleep more than you expect.
Large deer such as moose and red deer only need to sleep for 2-3 hours a day; medium-sized deer such as white-tailed deer and roe deer only sleep for tens of minutes a day!
Deer have a very short deep sleep time. During sleep, even if the weather changes or the position of the sun changes, they may adjust the resting area.
This way of sleeping can effectively avoid being caught and caught by predators.
So, if you want to sneak a photo of a sleeping deer in the wild, save the province!
Birds sleep on land for more than 12 hours a day, but during long-distance flights, they can sleep while flying. They sleep for an average of 41 minutes a day, and each nap is only 12 seconds.
Dogs sleep 12-14 hours a day. In other words, they spend about half of their time sleeping every day!
