Predators of Crows

In many places, crows are such a common sight that it can be easy to forget that they actually have many predators. And being “on the menu,” for a range of other animals is actually why these birds are so wary. That being said, here is everything you’ll want to know about the most common predators of crows and their relationship with them.

Natural Predators Of Crows

Crows have many natural predators. Birds of prey, for example, are common crow predators. This includes many species of eagles, hawks, falcons, and owls. They are powerful birds with sharp talons and beaks which they use to kill their prey. And while the rest hunt during the daylight hours, owls hunt crows at night and are a major threat to roosting crows.

Another common crow predator are actually ravens. Ravens aren’t birds of prey and despite being close relatives of crows there is no love between these species. Ravens will raid any crow’s nest they come across eating the eggs or young. Mammals like cats, coyotes, foxes, and raccoons will also prey on crows. Cats both feral and domestic are notorious killers of birds.

And they kill enormous numbers each year worldwide. Even though we associate them with being cuddly pets, they are natural hunters. And they may use a variety of techniques to catch and kill birds including crows. This may include stalking, pouncing, and ambushing them. Cats are also skilled climbers which gives them the ability to get to crow nests and eat their young.

Coyotes, foxes, and raccoons occasionally are able to take down crows when they are on the ground, however, they usually need to catch them unaware when the crows are distracted doing something else such as feeding. Although as skilled climbers with a keen sense of smell raccoons are also a threat to their nests.

There are a variety of snake species that kill and eat birds including crows both on the ground and in the trees. And there are many tree-climbing snakes that will eat their eggs and young as well.

Human Threats

While we don’t have a typical predator/prey relationship with crows humans do occasionally kill crows. And we do so both directly and indirectly. Hunting and trapping crows are used as a way to control their populations, particularly in rural areas where they are considered to be pests.

And in some areas, crows are even poisoned, which can have the unintentional consequence of killing a range of other species as well. Although nowadays non-lethal methods of deterring crows are becoming more and more popular such as the use of dead crow decoys and bird cannons among others.

That being said, humans are a threat to crows in other ways too. Crows are at risk when exposed to pollution, dangerous chemicals, and pesticides in their environment. Habitat loss due to urbanization and deforestation is also dangerous to crows as well and may lead to their deaths indirectly.

Adaptations of Crows to Avoid Predation

Crows are truly amazing birds. And they have developed a number of adaptations to avoid being killed by predators. Crows live in groups and they will use the power of their numbers to help drive predators and even people away. When crows spot an enemy the entire group attacks. This is known as mobbing and it’s highly effective and intimidating. Birds of prey in particular are often mobbed by crows.

Crows will also roost in large groups during the fall and winter months. This provides the birds with safety in numbers as they sleep. Crows use a variety of vocalizations and alarms to communicate with one another. And they even have specific calls to alert their group about specific crow predators such as hawks and eagles for example.

In addition to their highly aggressive behavior during the nesting season, crows will also build their nests in locations that are difficult for predators to physically get to. For example high up in tall trees. Often crows will choose tall trees that are located near open fields. This helps with visibility allowing the crows to quickly spot threats so they can sound the alarm and or mob them.

Impact of Predator Populations on Crow Populations

Predator populations can have a big impact on both the size and behavior of crow populations. For example, when there is a large number of birds of prey in an area, the local crow population may decrease not just from being hunted, but from the resident crows avoiding these areas or even in some cases abandoning their territory altogether.

Crows are adaptable and will often adjust their behaviors when there is a high number of predators. They may lay their eggs earlier or later in the nesting season than normal to avoid doing so when predators of crows are most active. Or crows may simply become more vigilant and mob threats even more aggressively to chase them out of the area.

Interestingly in some cases, having more predators actually benefits crows, since they may take out other crow threats. For instance, having a high number of eagles can help to reduce the local raccoon population. And that in return reduces the number of raccoon raids on crow nests.
