Rattlesnakes are hunted by other snakes, birds of prey, roadrunners, and several mammals. Documented examples include kingsnakes, indigo snakes, cottonmouths, hawks, owls, coyotes, bobcats, skunks, foxes, hogs, and greater roadrunners. The exact list changes with the rattlesnake species, its age, and the region.
These predators generally do not specialize in rattlesnakes. Available wildlife references describe encounters as opportunistic: a predator takes a rattlesnake when it can do so safely, rather than searching for rattlesnakes as its main food.

Which animals are known to hunt rattlesnakes?
There is no universal predator list for every rattlesnake. Texas Parks and Wildlife’s account of timber rattlesnakes names coyotes, bobcats, skunks, foxes, hawks, owls, and several snake-eating snakes. The snake examples include kingsnakes, indigo snakes, and cottonmouths. Other sources document additional cases, such as greater roadrunners eating rattlesnakes and young eastern diamondbacks being vulnerable to hogs and other predators.

| Other snakes | Kingsnakes, indigo snakes, cottonmouths | Listed as predators of timber rattlesnakes; kingsnakes are separately confirmed to eat rattlesnakes. | No source compares their success or frequency. |
| Birds | Hawks, owls, greater roadrunners | Hawks and owls appear on the timber-rattlesnake predator list; the National Park Service includes rattlesnakes among a greater roadrunner’s prey. | A broad predator list does not show how often a species kills a rattlesnake. |
| Mammals | Coyotes, bobcats, skunks, foxes, hogs | Coyotes, bobcats, skunks, and foxes are listed for timber rattlesnakes. Hogs and gray foxes are named among predators of young eastern diamondbacks. | These mammals are not established as rattlesnake specialists. |
| Predators of young eastern diamondbacks | Hogs, gray foxes, red-tailed hawks, kingsnakes, other carnivorous mammals and raptors | The Smithsonian specifically reports many predators for juveniles. | This age- and species-specific statement should not be generalized to all rattlesnakes. |
The strongest direct examples are kingsnakes, which California’s Department of Fish and Wildlife says eat rattlesnakes, and greater roadrunners, which the National Park Service lists as eating them. The other entries show that rattlesnakes can be prey for a wider community, but they do not establish a ranking.

Snakes that eat rattlesnakes
Kingsnakes
Kingsnakes are the clearest snake-on-snake example. California Department of Fish and Wildlife says kingsnakes are known to eat rattlesnakes and are resilient against rattlesnake venom. “Resilient” does not mean completely immune: it indicates an ability to withstand venom that would be dangerous to many animals, not invulnerability under every bite or dose.
A kingsnake record from California should also be read geographically. Kingsnakes occur in several regions and species, while rattlesnakes include many species with different sizes, behaviors, and habitats. A kingsnake that can overpower a particular rattlesnake is not proof that every kingsnake routinely kills every rattlesnake.
Indigo snakes and cottonmouths
Texas Parks and Wildlife includes indigo snakes and cottonmouths among snake-eating predators of timber rattlesnakes. This identifies them as documented predators in that context. It does not say that either species depends on rattlesnakes, encounters them frequently, or wins every confrontation.

The available references identify predation, but do not provide comparative success rates or a standard hunting technique that applies to all of these species.
Birds that prey on rattlesnakes
Hawks and owls
Hawks and owls appear in Texas Parks and Wildlife’s list of predators of timber rattlesnakes. The listing supports their inclusion among possible predators, but it does not identify one hawk or owl species as the most important rattlesnake hunter. Nor does it quantify how often these raptors take rattlesnakes compared with rodents, birds, or other prey.
Raptors can encounter snakes while hunting across open ground, woodland edges, or other suitable habitat. A predator list should therefore be treated as evidence that an opportunity occurs, not as evidence that rattlesnakes make up a large share of a bird’s diet.
Greater roadrunners
The National Park Service describes the greater roadrunner as an opportunistic predator and includes rattlesnakes in its prey list. Its White Sands National Park account says the bird will eat carrion and “pretty much anything they can catch,” including mice, lizards, scorpions, rattlesnakes, and other birds.
Recommended Free Tools
This is a direct statement that greater roadrunners eat rattlesnakes. The account does not quantify how often they do so or describe a single killing method that should be assumed for every encounter. Roadrunners should therefore be understood as versatile predators that may take a rattlesnake when conditions allow, rather than as dedicated rattlesnake hunters.
Mammals that may attack rattlesnakes
Coyotes, bobcats, skunks, and foxes
For timber rattlesnakes, Texas Parks and Wildlife lists coyotes, bobcats, skunks, and foxes as predators. These mammals have broad diets, so the listing does not make rattlesnakes a preferred or specialized food. A mammal may investigate, seize, or consume a snake when it has a favorable opportunity, but the cited material supplies no frequency estimate.
“Foxes” also covers more than one species in ordinary usage. The source’s predator list should not be expanded into a claim that every fox species in every rattlesnake range routinely hunts snakes. Local prey availability and the identity of the rattlesnake matter.
Rank #3
Hogs and other mammals
The Smithsonian identifies hogs, gray foxes, and other carnivorous mammals among predators of young eastern diamondback rattlesnakes. This is especially important because a juvenile rattlesnake is a different prey proposition from a large adult: it is smaller and may be easier for a predator to overpower or swallow.

The Smithsonian statement concerns eastern diamondbacks and their young. It should not be presented as a claim that adult rattlesnakes of every species have the same predators. It also does not establish whether hogs or gray foxes encounter juvenile snakes often enough to affect local rattlesnake populations.
Why young rattlesnakes face more danger
Age can change the balance between a rattlesnake and a predator. The Smithsonian reports that adult eastern diamondback rattlesnakes have no natural predators, while young eastern diamondbacks have many, including hogs, gray foxes, red-tailed hawks, kingsnakes, and other carnivorous mammals and raptors.
That statement is deliberately species-specific. “Adult eastern diamondbacks have no natural predators” should not be converted into “adult rattlesnakes have no predators” because other rattlesnake species may face different threats. Likewise, the presence of many juvenile predators does not mean that every young snake is attacked or that any one predator controls recruitment.
Size is only one possible reason for the difference. A young snake may be easier to handle, while an adult’s larger body and defensive capabilities can raise the risk for a predator. The cited sources do not measure the relative importance of those factors, so they should not be treated as a universal rule for every species.

UF/IFAS characterizes rattlesnake predation as opportunistic and says no species targets rattlesnakes. In practical terms, a predator may take a rattlesnake when it encounters one and the risk appears manageable, but it does not necessarily patrol an area looking specifically for rattlesnakes.
This explains why a long list of predators can coexist with a lack of frequency statistics. A coyote, hawk, or fox can be a documented predator without relying on rattlesnakes as a regular food source. The available sources identify who may eat a rattlesnake, not how many snakes each predator kills in a year or what share of the rattlesnake population is removed.

Why the predator list changes by place and species
Rattlesnakes are a diverse group distributed across different habitats. A timber rattlesnake in the region covered by Texas Parks and Wildlife is not ecologically identical to an eastern diamondback or another species elsewhere. The predators available, the size of the snake, and the amount of cover can all differ.
When reading a claim about a rattlesnake predator, check four details:
- Rattlesnake species: Is the statement about timber rattlesnakes, eastern diamondbacks, or an unspecified species?
- Age: Does it concern juveniles, adults, or both?
- Location: Was the observation or list made in a particular state, park, or habitat?
- Evidence type: Does the source directly say the animal eats rattlesnakes, or does it provide a broader predator list?
These checks prevent a local observation from becoming an inaccurate claim about all rattlesnakes.

How rattlesnakes respond to predators
Texas Parks and Wildlife says rattlesnakes generally seek escape and hide when possible. That behavior provides useful context: predator encounters are not necessarily prolonged fights. A snake may avoid detection, retreat, or use cover rather than remain exposed.
Because the sources do not establish a universal encounter sequence, avoid assuming that a rattle always leads to an attack or that a particular predator always approaches in the same way. Temperature, vegetation, surprise, and available escape routes can change what happens.
What to do if you see a rattlesnake
Predation is a natural-history subject, not a reason to approach wildlife. Keep people and pets away, give the snake room to leave, and do not attempt to provoke, capture, or kill it. If a snake is in a place where people or animals cannot safely avoid it, contact an appropriate local wildlife or animal-control service rather than handling it yourself.
Rattlesnakes’ tendency to hide or escape when possible is another reason to maintain distance. A concealed snake can be difficult to see, and observing from a safe position is preferable to trying to confirm which predator might attack it.
