Can you tell me if there are any poisonous snakes in the
Cook County area? I was at a lodge in Sauk Village where there is a lake
and a lot of weeds/trees. Someone opened a shed there and said that there
was a pygmy rattle snake in it. Is that a possibility?
According to the 1999 published "Field Guide to the Amphibians and Reptiles
of Illinois", Illinois Natural History Survey Manual #8, Massasauga
rattlesnakes have extremely few and scattered populations in Cook County
and verified specimens have been obtained. They are endangered and very
rare, and their venom does not have a serious effect on humans. They will
strike when surprised, otherwise, they flee.
