Best Answer: The standard is 10 to 12 hours a night. This is normally what birds sleep...seasonally a little more or less, depending on daylight hours. Most birds sleep when it is dark. In the wild, dark means danger.
While cows need relatively little sleep, giraffes sleep even less. On average, an adult giraffe sleeps just 1.9 hours per day. On the opposite end of the spectrum, brown bats sleep for 19.9 hours per day, giant armadillos sleep for 18.1 hours per day and North American opossums sleep for 18 hours per day.
