A barred owl eats mainly small mammals, including mice, voles, squirrels, and rabbits. Its diet also includes birds, amphibians, reptiles, fish, crayfish, and insects. This adaptable predator takes advantage of available prey rather than relying on one food throughout the year. An owl hunting beside a woodland stream may catch different animals from one searching a forest edge. The following guide explores ten natural foods, explains barred owl eating habits, and answers common questions about pets and poultry. These are wild prey—not foods to offer an owl.
10 Natural Foods Barred Owls Eat
Barred owls are opportunistic hunters, meaning they capture suitable animals when opportunities arise. Small mammals generally dominate their diet, but other prey can be important locally. These ten foods are not ranked by nutritional value or preference; their importance changes with habitat, season, and availability.
1. Mice
Mice are a major part of the barred owl’s diet. Their small size makes them manageable prey, and woodland mice frequently occupy the same habitats as these owls. White-footed mice are among the prey recorded in Ohio.
2. Voles
Voles are small rodents that can become especially important where they are abundant. Barred owls hunt them around suitable woodland openings and nearby grassy habitat. Maryland’s wildlife agency identifies meadow voles as a principal food for barred owls in that region.
3. Squirrels and Chipmunks
Barred owls eat squirrels, including flying squirrels, as well as chipmunks. These animals broaden the owl’s diet beyond smaller rodents. Flying squirrels are particularly relevant to a predator that frequently hunts after dark, although barred owls also hunt during daylight.
4. Rabbits
Rabbits are documented prey, including cottontails delivered to monitored nests. A rabbit provides a larger meal than a mouse, but that does not mean every rabbit is suitable prey. Barred owls can tear larger animals into pieces instead of swallowing them whole.
5. Birds
Barred owls eat birds such as jays, pigeons, and doves. They may surprise birds at nighttime roosts rather than chase them through the air. This hunting strategy allows them to capture prey that would be difficult to catch in active flight.
6. Frogs and Salamanders
Amphibians are another part of the barred owl’s varied diet. Frogs and salamanders provide feeding opportunities in moist forests and around wetlands. Their inclusion helps explain why barred owls are comfortable hunting in wooded habitats near water.
7. Snakes and Lizards
Barred owls sometimes capture snakes and lizards. Reptiles supplement their diet rather than replacing the small mammals that commonly sustain them. A general record of snake predation should not be treated as proof that every local snake species is regularly eaten.
8. Fish
Yes, barred owls eat fish. They can watch from an overhanging perch and drop toward the water, or wade into shallow areas while searching for prey. They are not specialist fishing owls, but aquatic hunting is a documented part of their behavior.
9. Crayfish
Crayfish—also called crawfish or crawdads—are established barred owl prey. Owls catch them in shallow waterways and may deliver them to their mates or young. Cornell’s monitored Indiana nest has recorded crayfish deliveries repeatedly over the years.
10. Insects
Beetles, crickets, and grasshoppers are among the insects barred owls consume. Some owls also hunt near artificial lights, where insects gather. These smaller prey items illustrate how flexible barred owl feeding can be, even though mammals usually receive more attention.
Barred Owl Hunting and Eating Habits
Barred owls combine patient observation with quick attacks. Their feeding behavior changes with the animal they are pursuing, from rodents beneath a perch to crayfish in shallow water.
How They Catch Prey
A barred owl often waits on an elevated perch, using sight and hearing to locate movement below. It then swoops down to seize its target. Hunting usually occurs around dusk and during the night, although daytime feeding is not unusual enough to suggest something is wrong.
Owls may also store uneaten prey temporarily in a tree cavity, branch fork, or another sheltered location.
How They Eat and Digest Food
Small prey may be swallowed whole, while larger animals are torn apart. Material that cannot be digested, including fur and some bones, is later brought back up as a pellet.
Pellet casting is normal owl behavior, not necessarily a sign of illness. Pellets also give researchers clues about the animals an owl has eaten.
What Eats a Barred Owl?
Although barred owls are predators, they are also vulnerable to other animals. Eggs and young face different dangers from those encountered by fully grown birds.
Natural Predators
The great horned owl is a major predator of barred owls, taking eggs, young, and occasionally adults. Large hawks can also pose a threat. Raccoons and weasels may raid nests, making the nesting stage particularly vulnerable.
Protecting Owls and Domestic Animals
Understanding an owl’s diet is more useful than assuming it is either harmless to every pet or constantly hunting domestic animals. Practical precautions can reduce conflict without disturbing the bird.
Sensible Precautions
- Keep cats indoors or in a secure outdoor enclosure.
- Supervise very small pets outside.
- House poultry in secure coops and covered runs.
- Avoid rodent poisons that can expose owls through contaminated prey.
- Contact a wildlife rehabilitator if an owl appears injured.
Secure enclosures are a more dependable defense for domestic birds than hoping an owl will ignore them.
FAQs
Will a Barred Owl Eat a Cat?
It can happen. Domestic cats have been identified in DNA-based research on barred owl diets. However, that evidence does not establish that adult cats are common prey or reveal the circumstances of every encounter. Keeping cats indoors avoids the risk.
Will a Barred Owl Eat a Chicken?
Yes. Domestic chickens were also identified in barred owl diet research. Protect poultry with a secure coop and overhead protection on outdoor runs, especially when birds would otherwise remain exposed around dusk or overnight.
Will a Barred Owl Eat a Small Dog?
Dogs are not typical barred owl prey. Reports of owls taking small dogs more often involve great horned owls. Nevertheless, supervise puppies and very small dogs outdoors. An owl swooping near a nest may be defending its young rather than attempting to feed.
How Much Does a Barred Owl Eat Per Day?
There is no single reliable number of mice or other prey items that applies to every barred owl. Food needs vary with body size, activity, weather, and breeding demands. Counting prey alone can also be misleading because a mouse and a rabbit provide very different amounts of food.
What Do Baby Barred Owls Eat?
Owlets eat animal prey supplied by their parents. The female initially tears food into small pieces for them. As the chicks grow, they become able to consume larger pieces and eventually whole prey.
