These animals can actually be heard, they make a shrieking chirping sound. Chipmunks like a more open area . The den entrance is usually two inches. Chipmunks have a hopping gait so the back feet land next to each other. They hibernate so if you see tracks in the winter it is something else.
Chipmunks are most active in the early morning.
The den below is in my Aunts yard and she sees them every morning scampering about her front yard from bush to bush Wild Turkey - These birds are making a comeback. Did you know they lost out being the US national bird by one vote. Wild Turkeys were live trapped in Virginia and then brought to New Jersey and released. The Turkeys are doing really well here in NJ and the population is getting bigger every year. This is a dead tree that is still standing in the woods near my house.
