What Do Rattlesnakes Eat?

Rattlesnakes are terrifying creatures.  Their most identifiable feature is the rattle that is found at the tip of their tails. They use this rattle to indicate their presence and to ward off intruders that make them feel threatened.

These predatory venomous snakes are part of the Crotaline family and there are over 65 species of rattlesnake that have been identified.

Rattlesnakes are often targeted by humans because they are so dangerous and, more importantly, because many humans harvest their rattles to sell these items on black markets.  In many regions, their populations have become severely threatened.

It is important to learn more about these natural predators because if you understand them better, you will find that there is no need to kill them.  They will only lash out and bite if they are provoked or threatened and their bites are seldom fatal.

What Do Rattlesnakes Eat?

Rattlesnakes are carnivore animals.  They hunt a variety of animals.  In most cases, they lie and wait for prey to pass by before striking.  They might also hunt for prey by visiting holes in the ground.  Rattlesnakes do not strangle their food.  Instead, they lash out, bite their prey, and allow the venom to do the killing for them.  If a rattlesnake bites prey, they can easily track their food by following the scent of their venom.

Here is a quick look at the most common food these snakes love to eat.

Small Mammals

Rattlesnakes love to hunt and catch small mammals.  They enjoy eating a variety of animals such as mice, rats, bunnies, kittens, hamsters, moles, mongoose, and squirrels.  In most cases, rattlesnakes simply hide away and wait for their prey to pass by before striking.  Their bodies are camouflaged and they keep their rattlers quiet while hunting for prey.

Rattlesnakes might also seek out their prey.  They will visit the holes of these small mammals and will attack their prey right in their burrows.

Birds And Eggs

Rattlesnakes will also hunt and eat birds.  They usually wait for a bird to pass by before lashing out to bite it.  These snakes will consume any small bird species that cross their path.  They also enjoy visiting the nests of birds to eat their eggs.  Rattlesnakes rarely climb trees but they can do it if they are desperate for a bite to eat.

Reptiles

These snakes will also catch and eat a variety of other reptiles.  They eat all sorts of lizards and can also sometimes eat other snakes.  Rattlesnakes have also been documented to catch and eat small crocodiles.

Amphibians

Amphibians such as frogs, toads, salamanders, newts, and caecilians are also good food sources for rattlesnakes that live close to water sources or that visit water sources for drinking.

Insects

These snakes might also consume various insect types.  It is especially young or small rattlesnakes that focus on insects.  They will eat insects like grasshoppers, crickets, beetles, ants, wasps, cockroaches, termites, and many others they find crawling or hopping about.

Water

These snakes do not need a lot of water to survive.  But they do need to consume at least their body weight in water every year to stay hydrated.  To drink water, they submerge their heads and ingest the water by opening their jaws.  When their jaws open, they can suck in water.
