This is Brodie with Illinois Extension and I’m here with a new “voice of the wild”

I have been sent this call by friends, family, and fans of the show. It causes more confusion than maybe any other animal in Illinois; I think that’s quite understandable – it just doesn’t quite fit in the taxonomy of soundmakers we have in our heads. It seems to have the regularity of an amphibian, the numbers for an insect, and the habitat and loudness of a bird. It is in-fact none of the above. The call belongs to a mammal; one with adorable cheek pouches suitable for transporting acorns; it belongs to the eastern chipmunk.

The chipmunk’s clucking alarm call is often given in response to a bird of prey gliding through the chipmunk’s shrubby wooded territory. Once one starts clucking away, others will join so that eventually the whole community of chipmunks has stopped their foraging to scan for and alert others about the potential threat. Chipmunks are best heard between late summer and fall. That’s when they’re stocking their burrows with acorns to eat throughout the winter. Here’s the eastern chipmunk again.
