Chipmunk

We have a chipmunk that eats the seeds on the ground that fall out of the bird feeder. We think it lives in a stack of twigs we put near the house, near the birdbath. I wondered if the chipmunk could hop up to the birdbath to drink the water, and figured it probably could crawl up a nearby bush, and sure enough just then, lickety split, it zoomed up the branch and drank from the birdbath, and zoomed back down again. It also likes to hang out at the pond, unless that is a different chipmunk.
