1) Chickadees can remember where they stash their food for at least 28 days. That's better than my memory.
2)They reduce their temperature by 10-12 degrees C. at night to conserve energy.
3) They have a hierarchy based on aggressiveness in their flocks.
4) They have 15 calls to communicate in the flock.
5) Flocks are normally 4-12 birds composed of mates with some juveniles thrown in.
