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.
These birds tend to have periods of rest, possibly sleep, either at a certain time during the 24 hour cycle, or in short periods at different times of the day. The overall length of time they spend sleeping tends to be a fraction of the time at more southerly latitudes where it gets dark at night.
