Common Kingsnake

 

 
36"-82", a large black snake with highly variable back and belly pattern.  In Kentucky, some have a faint chainlike dorsal pattern; others have a salt and pepper color pattern.  Found throughout the southern U.S. from coast to coast, in a number of subspecies, in a diverse array of habitat types.  Active during the day, but nocturnal uring the summer.  It is a strong constrictor, specializing on other snakes (hence the name kingsnake) including poisonous ones, as well as rodents, birds, and eggs.
