What Great Horned Owl Eat and their Food
The diet of Great Horned Owls varies greatly, and they are raptors that eat meat. They eat many kinds of mammals and birds. They typically eat rabbits, mice, hare, American Coots, and a wide range of other animals. Some of them include chipmunks, voles, gophers, rats, woodchucks, marmots, prairie dogs, bats, skunks, house cats, porcupines, loons, grebes, owls, hawks, crows, ravens, doves, and mergansers. While these form the central part of their diets, they also eat insects, reptiles, invertebrates, fish, and carrion at times. You may see them hunting during the day, even though they typically hunt at night. They watch prey from up high and then fly down to capture it. They may stalk small animals around ground obstacles by walking. In the winter, they may store prey they don’t eat, allowing it to freeze and then eating it later by warming it with their bodies.
These birds are very large and powerful making them very capable of handling preys of a variety of sizes. This nocturnal raptor is a carnivorous bird that hunts small mammals like rabbits and mice, birds like the duck and quail. Its swallows its small preys whole but tears large prey limb from limb before indulging.
Where Great Horned Owls Live and their Habitat
The great horned owl lives in woodlands particularly young woods intermingled with open areas, along cliffs and canyons and at the edge of forests. Great Horned Owls like to hang out in secondary-growth woodlands, agricultural areas, orchards, and swamps. You can spot them in mixed, coniferous, and deciduous forests. They tend to gravitate toward old-growth stands in some places, like the southern Appalachians. Great Horned Owls are present in fields, pastures, agricultural areas, and wetlands, which are all open areas, but you’ll also find them in forested areas. If you live in the suburbs or the city, keep a lookout because they live in these areas, too. If you’re ever in the desert, you may see their nests in junipers and on cliffs.
Range and Migration
Great Horned Owls live throughout North America. You’ll find them across the United States, far north into Canada, and in many parts of Alaska. They are also present in most of Mexico and some Central American countries. They are some of the most common owls in North America, and they live in just about any semi-open habitat from near the equator up to the Arctic region. The Great Horned Owl doesn’t migrate regularly, but some individuals may head south some in the fall and winter. So wherever you’re at in North America, there’s a good chance that there are Great Horned Owls somewhere nearby.
Great Horned Owl Lifecycle
For the Great Horned Owl, the months of January and early February are prime mating seasons. As they do not make their own nests, they use nests abandoned by other birds to begin nesting. The female bird lays eggs two to three dull whitish eggs that take about 4 weeks to hatch. Both the male and female birds practice incubation and fend for the owlets. The owlets leave the nest at the age of one to two months and can fly on their own at 9-10 weeks old.
Great Horned Owls may start nesting in the last part of winter in the north. This could be so young can learn how to hunt before winter begins again. The male Great Horned Owl shows off his flight skill to and feeds the female. These owls usually may use nests of other big birds, like crows, hawks, herons, or eagles, and their nests are high off the ground, typically between 20 and 60 feet. They usually don’t add much in the way of nest material, except for perhaps some feathers. You may also find their nests on the edges of cliffs, in tree stumps, and maybe on the ground. If you find a cave, don’t be surprised if you see a nest of a Great Horned Owl in there!
