Chipmunks get very chummy. Takes a bit of time but they'll take nuts right from your hand. I had one that sat on my left shoulder and dug into my left shirt pocket incessantly because often there was a peanut in there.

They stockpile food by the ton and retire to their den for the winter as soon as they think they have enough food. In this case, it went underground right after Labor Day and never emerged until the first week of April (they do not hibernate - they just sleep a lot and snack from time to time).

They apparently spend 75% of their life sleeping.

Cute film documenting how a photographer and a chipmunk became good friends. Through food excercises done to gain it's trust (The chipmunk's!) the chipmunk eventually trusts the guy enough for a good source of food, and nothing else.

This is a classic silent short movie that shows how patience and ingenuity, on both sides, can bring man and creature together. This is a nice part of history as William L. Finley was a great saving influence to many of our planet's creatures and resources.
