Did you know that some species of owls actually eat fish? It may seem unbelievable, but it’s true! While we typically think of owls as predators of rodents, insects, and other small animals, some owls have adapted to include fish in their diet.

So, how exactly do owls catch and eat fish? It turns out that these birds of prey are quite skilled at fishing, using their sharp talons and powerful beaks to grab and kill their slippery prey. Additionally, owls have unique digestive systems that allow them to process and extract nutrients from the bones, scales, and other tough parts of fish that other animals might find difficult to digest.

While it may be surprising to learn that owls can eat fish, it’s just one of many fascinating aspects of these amazing birds. Keep reading to learn more about the curious case of fish-eating owls and other unexpected prey that these feathered hunters pursue.

The curious case of fish-eating owls

As we mentioned earlier, owls are known for preying on small animals such as rodents and insects. However, some species of owls have developed a taste for fish, which may seem like an unusual choice of prey for a bird of prey. Let’s take a closer look at this curious case of fish-eating owls.

One of the most common types of owls that eat fish is the short-eared owl, which can be found in wetland habitats around the world. These birds are often seen flying low over water sources, using their keen eyesight to spot fish swimming near the surface. Once they have identified their target, short-eared owls use their sharp talons to grab the fish and kill it with a quick bite to the neck. They then swallow the fish whole, using their strong beaks to break down any tough parts before digestion.

How do fish-eating owls differ from other birds of prey?

While many birds of prey hunt and kill their prey on the ground or in trees, fish-eating owls have adapted to a very different environment: water. As a result, they have developed unique physical characteristics and hunting strategies that set them apart from other birds of prey. For example, many fish-eating owls have large, broad wings that allow them to fly slowly and steadily over water without getting wet. They also have keen eyesight and the ability to turn their heads almost all the way around, which helps them spot and catch fish even in murky water.

What other unusual prey do owls hunt?

  • Barn owls are known for preying on bats, which they catch in mid-air using their sharp talons and beaks.
  • Great horned owls have been known to prey on skunks, which they kill with a powerful bite to the neck.
  • Snowy owls have been observed catching and eating lemmings, which are small rodents that live in the Arctic tundra.

Why are owls such successful predators?

Owls have several adaptations that make them highly effective hunters. For one, their large, forward-facing eyes give them excellent depth perception and the ability to see in low-light conditions. Additionally, their silent flight allows them to approach prey without being detected. Finally, their powerful talons and sharp beaks give them the ability to catch and kill a wide range of prey, from small rodents to fish and even other birds of prey.

The anatomy of an owl’s digestive system

Owls have a unique digestive system that enables them to consume a wide variety of prey, including fish. Their digestive tract consists of several specialized organs that work together to break down and extract nutrients from their food.

The first step in an owl’s digestive process occurs in their mouth, where they use their sharp beak and talons to tear apart their prey. The food then passes through the esophagus into the proventriculus, a specialized glandular stomach that secretes enzymes and acids to break down the food further.

The gizzard

Next, the food moves into the gizzard, a muscular organ that grinds the food into smaller pieces using small stones and other materials the owl has swallowed. The gizzard acts as a filter, removing indigestible materials from the food before passing it on to the rest of the digestive system.

The small intestine

After passing through the gizzard, the food enters the small intestine, where nutrients are absorbed into the owl’s bloodstream. The small intestine is lined with small finger-like projections called villi, which increase the surface area for absorption.

  • Chyme: The partially digested food that enters the small intestine from the gizzard.
  • Pancreas: A gland that secretes digestive enzymes and hormones into the small intestine.
  • Bile duct: A tube that carries bile from the liver to the small intestine to aid in the digestion of fats.

The cloaca

Finally, the remaining indigestible materials pass through the large intestine and into the cloaca, a chamber that serves as the exit point for both digestive and reproductive waste. From there, the waste is expelled from the owl’s body as pellets.

  • Cloacal bursae: Two pouches in the cloaca that store sperm and allow for fertilization during mating.
  • Coprophagy: The process by which owls ingest their own pellets to extract additional nutrients.
  • Cloacal muscles: Muscles that control the opening and closing of the cloaca.

Understanding the unique anatomy of an owl’s digestive system helps us appreciate their remarkable ability to consume a wide range of prey, including fish. Next time you see an owl in the wild, take a moment to marvel at the incredible complexity of their internal workings.

What types of fish do owls eat?

Owls are known for their unique ability to hunt and consume a wide range of prey, including fish. Fish make up a significant portion of an owl’s diet, especially for those that live near water bodies. But what types of fish do owls prefer?

It’s important to note that different species of owls have different hunting habits and preferences, and therefore their diets can vary. However, some of the most common types of fish that owls eat include:


Trout is a type of freshwater fish that can be found in many rivers and lakes around the world. They are a popular prey for owls because they are relatively easy to catch and have a high nutritional value. Owls can catch trout either by swooping down and grabbing them with their talons or by diving into the water to catch them.


Perch is another type of freshwater fish that is often preyed upon by owls. They can be found in many different types of water bodies, including lakes, rivers, and streams. Owls typically catch perch by swooping down and grabbing them with their talons.


Catfish is a bottom-dwelling fish that can be found in both freshwater and saltwater environments. They are a popular prey for owls because they are relatively large and provide a high amount of nutrition. Owls typically catch catfish by diving into the water to grab them with their talons.

Other types of fish that owls may eat include salmon, herring, and eels. The type of fish that an owl hunts will depend on factors such as its geographic location, hunting habits, and prey availability.

Surprising facts about an owl’s hunting skills

As natural predators, owls have evolved to become some of the most efficient hunters in the animal kingdom. Here are some interesting and surprising facts about their hunting skills.

Owls can fly silently thanks to their specially adapted feathers that muffle sound. This makes them incredibly stealthy hunters, able to approach prey without being heard. They also have excellent vision and can spot prey from far away.

Owls have powerful talons

  • Owls have four toes on each foot, with two toes facing forward and two toes facing backward. This arrangement allows them to grip their prey tightly.
  • Owls’ talons are incredibly strong, capable of exerting up to ten times their own body weight in pressure. This means that even larger prey is no match for an owl’s grip.

Owls are nocturnal hunters

Most owl species are active at night, when their prey is most vulnerable. Their keen sense of hearing allows them to locate prey in complete darkness, and their eyes are adapted to see well in low light conditions.

Owls are opportunistic hunters

  • Owls will eat almost anything that they can catch, including insects, rodents, birds, and even fish. This flexibility allows them to survive in a variety of environments.
  • Owls have been known to store extra food for later by hiding it in trees or other secure locations. This behavior helps them to survive during times when prey is scarce.

Overall, owls are fascinating creatures with incredible hunting skills. Their silent flight, powerful talons, nocturnal nature, and opportunistic behavior make them effective and adaptable predators.

How do owls catch fish?

Owls are well known for their incredible hunting skills and are known to prey on a wide variety of animals, including fish. However, have you ever wondered how these nocturnal birds manage to catch their slippery prey? Let’s take a closer look at their fishing techniques.

Firstly, it’s important to note that not all owl species hunt fish. Some of the species that do are the great gray owl, the snowy owl, and the short-eared owl. These birds typically hunt in wetland areas such as marshes, ponds, and lakes.

Stealth and precision

When it comes to catching fish, owls rely on their stealth and precision. They use their sharp talons to grab the fish out of the water, often without getting their feathers wet. These talons are specially adapted to catch and hold onto prey, with sharp, curved claws that can exert a powerful grip.

The owl’s exceptional hearing is also crucial in this process. They can detect the sound of fish moving in the water, even in complete darkness. Once they locate their prey, they swoop down and grab it with their talons, often in one swift motion.

Patience and strategy

In addition to stealth and precision, some owl species also employ a patient and strategic approach to fishing. The great gray owl, for example, is known to sit patiently at the edge of a water body, waiting for a fish to swim by. They will then swoop down and grab the fish in their talons.

The snowy owl, on the other hand, is known to hunt from a perch overlooking the water, waiting for the right moment to strike. They will then fly out and grab the fish in their talons, before returning to their perch to consume it.


Owls are adaptable hunters and will adjust their fishing techniques depending on the circumstances. For example, the short-eared owl is known to fly low over the water, scanning for fish. When they spot a fish, they will hover momentarily before diving in and catching it in their talons.

Overall, owls are remarkable hunters with a diverse range of fishing techniques. Their stealth, precision, patience, and adaptability make them formidable predators, capable of catching even the slipperiest of fish.

What other unexpected prey do owls hunt?

While most people associate owls with hunting rodents and small mammals, these nocturnal predators are also known to catch a wide variety of other creatures. One of the most unexpected prey items that owls have been known to hunt are fish.

When an owl catches a fish, it typically happens near the surface of a body of water. Some species of owls, like the barred owl, have even been observed wading into shallow water to catch fish with their talons.

Other unusual prey items:

  • Birds: While it may seem surprising, some species of owls, like the great horned owl, will hunt and eat other birds. They often prey on smaller birds, such as songbirds and waterfowl, but have also been known to take down larger birds like hawks and even eagles.
  • Reptiles: Owls are also known to hunt and eat a variety of reptiles, including snakes, lizards, and even turtles. They have been observed using their sharp talons to grab and kill their prey before swallowing it whole.

Unusual hunting techniques:

In addition to their unexpected prey items, owls are also known for their unique hunting techniques. One of the most fascinating methods is known as “plucking.” Some species of owls, like the snowy owl, will actually pluck their prey before eating it. This involves removing the feathers or fur from their catch to make it easier to consume.

Another unusual hunting technique used by some owls is called “whisper hunting.” This involves hunting in complete silence to avoid alerting their prey to their presence. Some owls, like the barn owl, are particularly skilled at this technique and can even hear the heartbeat of their prey from several feet away.
