Cottonmouths are a quirky and very interesting species of snake. Cottonmouths
are opportunistic feeders and will prey upon a variety of items, including living and dead animals. Several times over
the years I have observed unusual Cottonmouth behavior, and I wrote and co-authored the two Herpetological Review notes
below concerning their behavior and feeding.
During road cruising once in Louisiana, west of New Orleans, I also remember interesting behavior
by a small adult (c. 18" total length) W. Cottonmouth on the road. As I drove up to the snake I noticed it was rubbing
the tip of its snout on the road surface numerous times. I got out of my vehicle to investigate and found that the Cottonmouth
was trying to pry up a very flattened and dead, adult Broad-banded water snake off the road surface!

and Copperheads are born with yellow tail tips at birth. They use their brightly colored tails as a lure to attract small
prey. Their yellow tails fade by their second or third year. Photo by Sandi Chapman.
