Catching Chipmunks

I’ve had the chipmunk traps out for about a week now.  And in that time, I have trapped a total of five chipmunks.  I had three within the first two days, then it took another day or two to catch the others.  I had gone a couple of days without any action, and then I got this guy. 

I’ll leave the traps out for a few more days and as soon as it has been four or five days without any action I’ll consider them all caught and take them in.  If I leave them out longer with no chipmunks around, eventually I will start catching birds, and that is a real pain to deal with.  They totally freak out, even though all I’m doing is trying to let them out.
