What Kind Of Bird Attacks Cats?

Cats and birds have a complicated relationship. While cats are known for hunting and killing birds, did you know that some birds actually attack cats? If your feline friend has ever been divebombed or chased by an angry bird, you’ll want to find out which avian species are most likely to go after cats.

If you’re short on time, here’s a quick answer to your question: birds most likely to attack cats include mockingbirds, blue jays, cardinals, and crows.

Birds That Aggressively Defend Their Nests

When it comes to birds defending their nests, some species can be particularly aggressive, especially if they perceive a threat to their eggs or chicks. Here are some birds known for their defensive behavior:


Mockingbirds, known for their exceptional vocal abilities, are also notorious for their aggressive nature when it comes to defending their nests. These feisty birds will fearlessly dive-bomb intruders, including cats, in an effort to protect their precious eggs or hatchlings.

It’s not uncommon to see a mockingbird relentlessly chasing away any potential threats from their nesting area.

Blue Jays

Blue Jays are another bird species that aren’t afraid to put up a fight when their nests are at risk. With their striking blue plumage and distinctive crest, these birds are not only stunning to look at but also fiercely protective of their young.

They will swoop down on any perceived threat, including cats, making loud screeching sounds to intimidate and drive them away.


Cardinals, with their vibrant red feathers and melodious songs, may seem peaceful, but don’t be fooled. These birds are known for their aggressive defense of their nests. If a cat or any other predator gets too close, Cardinals will engage in aggressive behavior, including dive-bombing and squawking loudly to warn the intruder to stay away.

Crows and Ravens

Crows and ravens are highly intelligent and social birds that are not only known for their problem-solving abilities but also for their protective nature. If they perceive a threat to their nests, they will not hesitate to mob the intruder, including cats.

These birds will gather in large numbers, cawing loudly and dive-bombing the potential threat until it retreats.

It’s important to remember that these birds are simply defending their nests and young, acting on instinct. It’s best to keep cats indoors or supervised to prevent any potential conflicts with these feisty avian protectors.

Why Birds Attack Cats

Birds attacking cats may seem like an unusual occurrence, but it is not as uncommon as one might think. There are several reasons why birds exhibit this behavior towards our feline friends. Understanding these reasons can help shed light on why birds attack cats and how we can prevent such incidents from happening.

1. Protecting Eggs and Chicks

One of the main reasons why birds attack cats is to protect their eggs and chicks. Birds, especially those that nest on the ground or in low bushes, feel threatened when a cat approaches their nesting area. They see cats as potential predators that could harm their vulnerable offspring.

In an attempt to defend their young, birds may swoop down and peck at the cat, trying to drive it away. This behavior is particularly common during the nesting season when birds are hyper-vigilant about protecting their nests.

2. Defending Territory

Birds are territorial creatures, and they fiercely defend their nesting territories from any perceived threats. When a cat enters their territory, birds may see it as an intruder and respond by attacking.

This territorial defense behavior is more common in birds that nest in urban or suburban areas, where cats are often present. The birds’ instinctual need to protect their territory and ensure the survival of their offspring can lead to aggressive behavior towards cats.

3. Instinctive Behavior

Another reason why birds attack cats is rooted in their instinctive behavior. Birds have evolved over millions of years to be agile and quick in flight, and their natural response to potential threats is to flee or fight.

When a cat approaches a bird too closely or exhibits predatory behavior, the bird’s instincts kick in, and it may resort to attacking the cat as a means of self-defense. This instinctive behavior is not limited to certain bird species but can be observed in various types of birds.

It is important to note that not all birds will attack cats. Some species may simply fly away or vocalize their distress rather than resorting to physical aggression. Additionally, the intensity of bird attacks may vary depending on the individual bird’s personality and previous experiences with cats.

While it can be entertaining to watch birds stand up to cats, it is crucial to ensure the safety and well-being of both animals. If you have a cat and want to prevent bird attacks, consider keeping your cat indoors, especially during the nesting season.

Providing your cat with plenty of environmental enrichment and supervised outdoor time can help satisfy their natural hunting instincts without posing a threat to birds. Remember, coexisting peacefully with our feathered friends is possible with a little understanding and proactive measures.

How to Keep Cats Safe from Aggressive Birds

Supervise Outdoors

One of the best ways to keep cats safe from aggressive birds is to supervise them when they are outside. By keeping an eye on your cat, you can intervene if you notice any signs of a bird attack. This is especially important if your cat is known to be curious or has a tendency to chase birds.

By supervising your cat, you can ensure their safety and prevent any potential harm from aggressive birds.

Use Deterrents

If you have noticed that a particular bird is constantly attacking your cat, you can use deterrents to keep them away. There are various bird deterrent products available on the market, such as bird spikes, reflective tape, or bird repellent sprays.

These deterrents can be placed in areas where your cat spends time, such as near windows or in your backyard. By using deterrents, you can discourage aggressive birds from approaching your cat and reduce the risk of an attack.

Provide Shelter and Escape Routes

Another way to keep cats safe from aggressive birds is to provide them with shelter and escape routes. Cats should have access to a safe space where they can retreat if they feel threatened by a bird. This can be a covered outdoor enclosure or a designated area indoors where your cat can go to escape from potential attacks.

Additionally, providing escape routes such as elevated platforms or trees can allow your cat to quickly get away from aggressive birds and find safety.

Remember, it is important to prioritize the safety and well-being of your cat. If you are unsure about how to deal with aggressive birds or if your cat has been injured in an encounter with a bird, it is recommended to consult with a veterinarian for further guidance.

When to Be Concerned About Bird Attacks

Repeated Divebombing

If you notice a bird repeatedly divebombing your cat, it may be a cause for concern. Divebombing is a defensive behavior that birds exhibit when they feel threatened or when they perceive a potential threat to their nests or young ones.

While some birds engage in occasional divebombing as a warning, repeated and aggressive attacks can be dangerous for your cat. It is important to take precautions to protect your pet from potential harm.

Drawing Blood

While most bird attacks on cats may not cause serious harm, there are instances where the bird’s beak or talons can draw blood. If your cat gets injured by a bird during an attack, it is crucial to seek immediate veterinary attention. Even minor wounds can lead to infections or other complications.

Additionally, if your cat seems distressed or in pain after an attack, it is best to consult with a veterinarian to ensure there are no underlying injuries that need to be addressed.

Nesting Season

During nesting season, birds can become more territorial and protective of their nests. This can lead to an increase in bird attacks on cats that come into close proximity to nesting areas. It is important to be aware of the nesting season for different bird species in your area and take precautions to keep your cat away from these potentially dangerous situations.

Avoiding known nesting areas and keeping your cat indoors or supervised while outside can help reduce the risk of bird attacks.

If you are concerned about bird attacks on your cat, it is always a good idea to consult with a veterinarian or a bird expert for guidance on how to handle the situation. They can provide specific advice based on your location, the bird species involved, and the behavior exhibited by the bird.


Birds like mockingbirds, blue jays, and crows are surprisingly willing to fend off cats they see as a threat. While occasional divebombing is mostly just annoying, repeated attacks or actual injuries mean it’s time to take action.

Keep your cat safe by being vigilant during nesting season, using deterrents, and giving your pet plenty of shelter and escape routes from angry birds.
