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.
Nests are for chicks to hatch and grow up in. By the end of the season the nests full of bird poo, spilled food, and sometimes tragically, a dead chick, are simply abandoned. For birds, sleep is all about safety and warmth. If they are a smallish songbird they won't sleep on the ground because a cat will get them, and they won't sleep on an exposed branch because an owl will get them.
