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.
Cockatiels and parakeets also puff their feathers when they're going to sleep -- so it can be hard to tell whether they're cold or napping. If your bird looks puffy during the daytime hours, ensure that he's not in a draft and that the temperature in the room is not too cool.
