Like Baby Humans, Baby Owls Experience Large Amounts of REM Sleep

You call a person who stays awake late a "night owl," but a new study suggests that humans have something in common with the birds even while asleep. A study by researchers at the Max Planck Institute for Ornithology and the University of Lausanne in Switzerland found that baby owls sleep like baby humans, spending a larger portion of their resting hours in REM-sleep than their grown-up counterparts.
