FUN FACTS

1.Like many reptiles, the incubation temperature of their eggs may determine the offsprings' sex; warmer temperatures usually favor males while cool temperatures favor females.

2.The yellow rat snake, or chicken snake, is known to feed on domestic fowl (i.e. chickens) and their eggs. This practice is how they came to receive one of their common names, "chicken snake".

3.Like pythons and boas, rat snakes are constrictors, which suffocate their prey.

4.Yellow rat snakes spend much time underground prowling through rodent burrows.

5.Truly arboreal, yellow rat snakes will commonly climb trees to reach and devour birds and their eggs. The snake is known to climb to heights of 60 feet search for prey in trees.

ECOLOGY AND CONSERVATION

Many other important predators (i.e. birds-of-prey) feed on young snakes. This means that snakes fulfill roles as both predators and prey in regional food chains. Yellow rat snakes are also valuable in their role of curbing rodent populations, especially those near human settlement and agricultural settings. Because rodents often live in barns and garages, this is where most humans encounter them. Unfortunately, many snake species suffer from habitat destruction and alteration.
