I use an old tin can to pour sunflower seeds from the bag they come in to the bird feeders. If I set the can down for a second some little chipmunk always jumps in for the last few seeds at the bottom.
@anazad511 Thank you so much! :) This is a wild chipmunk, there are about a dozen of them that live in the woods around the garden and they come out when I fill the feeders. I can't touch them or anything like that. They are not pets. :)
