Jonesella - NO! Not poisonous. They will bite if you pick them up wrong, and it hurts, but they have no venom. Racers eat rodents and insects and small birds. Good things to have around your landscape. Not so good around a chicken coop if you have tiny chicks, but you can use screens and keep them out until the chicks are bigger.

Nope, not a Corn, and definitely not a Copperhead. This is an Eastern Milk Snake(Lampropeltis triangulum triangulum), a member of the family that includes the King Snakes. The pattern on the head is different from a Corn, and these look nothing at all like a Copperhead, not even close.

The only poisonous snakes in Wisconsin will have a rattle at the end of their tails. Also, those are very very rare here. Also, snakes are your friends. They will keep rodent populations under control. They are generally very shy and won't bother you unless messed with, or stepped on (do not try to pick up).

yup. The color is it's belly - it will display this when threatened. (To make you think it's poisonous) It is harmless and adorable.
