Iowa has a reputation for being a series of cities, agricultural fields, and cattle farms, which might make you suspect that it isn’t ideal for seeing birds such as owls. On the contrary, the state is home to nine different species of owls, and many of them stick around all year long.
That means whether you are looking for great horned owls in Des Moines, Barn owls in Cedar Rapids, or Snowy owls in the winter plains, you’ll probably be able to find them.
In fact, most owls love to go hunting in those rolling plains and cornfields, so keep an eye open any time of day, since different owls love to hunt morning, noon, and night.
The state also boasts several birding trails, including the Great River Birding Trail and the Siouxland Trail.
Here is the list of owls in Iowa:
- Great Horned Owl
- Barred Owl
- Barn Owl
- Long-Eared Owl
- Short-Eared Owl
- Northern Saw-Whet Owl
- Snowy Owl
- Burrowing Owl
- Eastern Screech Owl
9 Types of Owls in Iowa
1. Great Horned Owl
- Scientific name: Bubo virginianus
- Size: 20 inches long
- Weight: 32-88 ounces
- Wingspan: 40-57 inches
Most people recognize the great horned owl thanks to its appearance in movies like the Harry Potter franchise and its characteristic hoot. These massive owls can weigh up to five-and-a-half pounds. They have massive claws, and they’re strong fliers, which enables them to take down fierce prey like ospreys and falcons.
Once they clench their claws around something, it takes 28 pounds of force to pry them back apart.
These birds live in every part of North America, from Mexico to the northern parts of Alaska. It’s one of the most common owls and makes itself home in deserts, mountains, forests, and prairies. The great horned owl is just at home in cities as it is in the suburbs and wilderness areas.
All this means that you have a good chance of being able to see one. You can find it anywhere in Iowa.
Look for the giant bird with yellow eyes and long tufts of hairs near its ears. They can be gray or cinnamon with barring over a cream or light gray body.
If you were wondering, they can’t really move their heads 360 degrees, despite what you might have heard. They can swivel their head over 180 degrees, though, giving the illusion that they’re turning their head completely around. These birds can’t move their eyes from side to side, so they move their heads back and forth instead.
2. Barred Owl
- Scientific name: Strix varia
- Size: 17-20 inches long
- Weight: 16.6-37 ounces
- Wingspan: 39-43 inches
The barred owl is similar in length to the great horned owl, but they weigh much less. They are mottled brown and white with distinct bars across their entire body. The bars on the breasts are vertical and horizontal on the rest of their bodies.
These aren’t noisy birds. They generally keep quiet, though you can sometimes hear them call out during the day.
Barred owls stick to forested areas, whether that’s the swamp or high up a mountain. You won’t find them in cities or prairies. They live across the entire eastern US and up into Canada. In recent decades, the birds have expanded their range, and now there are also populations in the Pacific Northwest. They don’t migrate during their lives. They stick to one place, making their home in trees. However, if they can’t find food, they will travel long distances to hunt.
Great horned owls hunt the barred owl, while the barred owl is pushing the endangered spotted owl out of its territory.
Barred owls live in most of Iowa all year long, except for the northeastern corner where they may only venture rarely.
3. Barn Owl
- Scientific name: Tyto alba
- Size: 12.5-16 inches long
- Weight: 14-24.7 ounces
- Wingspan: 40-50 inches
The barn owl got its name because it likes to live in abandoned barns and other buildings in rural areas. They’ll also nest in the cavities of trees. They hunt by soaring across open areas and listening for prey. As you might guess, they have excellent hearing.
You can tell it’s a barn owl by its distinct face. They have pure white, heart-shaped faces with large, dark eyes. Their wings and back are gray, golden, or cinnamon and somewhat mottled. The undersides of their wings are white, as is their chest, which means they look all-white from underneath when they’re flying. They don’t have any ear tufts as the great horned owl does.
Young barn owls will fly far away from where they were hatched to find their own territory, but once they find a spot they like, they stay there for life.
You can find barn owls across the US and Mexico except in a few parts of the central northern states like North Dakota. The owl lives in every part of Iowa, so your chances of seeing them are good.
4. Long-Eared Owl
- Scientific name: Asio otus
- Size: 13.8-15.8 inches long
- Weight: 7.8-15.3 ounces
- Wingspan: 35.5-39.5 inches
Long-eared owls have surprisingly long ear tufts, which is how they got their name. The tufts are black with bits of buff or orange. They have two white lines between their yellow eyes.
They’re slender with mottled brown bodies. These nocturnal birds roots in trees and hunt in grasslands or open country.
You can often identify them by their hoots, squeals, and barks. They are quite vocal. They usually only migrate at night, but they can fly exceptionally long distances. Researchers have identified birds that have traveled from Canada to Mexico in a single year.
Those who live in or are visiting Iowa should look for this owl all year long in just the center of the state. Otherwise, these owls hang out in Nebraska during the winter and travel north the rest of the year.
5. Short-Eared Owl
- Scientific name: Asio flammeus
- Size: 13.4-17 inches long
- Weight: 7.3-16.9 ounces
- Wingspan: 33.5-40.5 inches
You’re right if you guessed that these owls have short ear tufts. Owls have ear tufts to help direct sound to their ears, enabling them to hunt and hear potential predators. Short-eared owls have ear tufts, but they’re small, like little horns.
They’re distinctive owls because they have brown and white mottling edged in black bars. The face is cream with dark black outlines around the yellow eyes.
Their distinctive appearance makes it easier to spot them, but the fact that they are active during the day makes it even easier to see them. They even have a distinct, moth-like flight pattern that makes identification even simpler.
Unlike many owls, they don’t prefer wooded areas. They like open fields and grasslands, where they sit on the ground and watch and listen for prey to catch. Then, they fly up and dive down to catch their prey. They even nest in the ground.
Short-eared owls live in Iowa all year long, so you have a chance of seeing them no matter what the weather looks like.
6. Northern Saw-Whet Owl
- Scientific name: Aegolius acadicus
- Size: 7.1-8.3 inches long
- Weight: 2.5-5.3 ounces
- Wingspan: 16.5-19 inches
Northern saw-whet owls are petite, about the size of a robin, with a mottled brown and white body. They have big yellow eyes and a heart-shaped face with a small, white V-mark between their eyes.
They are difficult to see, especially because they hunt at night, but if you listen for their shrill call, you’ll know they’re nearby. During the day, they nest in cavities in trees at about eye height, so you might see them if you look carefully. Don’t disturb the sleeping birds, though!
They only live in forests, particularly mature forests, so don’t look for them in open areas or cities. They migrate long distances to breed. They eat small rodents like mice and shrews. They’ll also eat birds like chickadees, juncos, waxwings, and sparrows.
They live across the US, with scarce breeding populations in the South and permanent populations in the northern part of the country and throughout the Rocky Mountains and western Coastal ranges. Nonbreeding populations exist across the rest of the country.
The northern saw-whet owl lives in Iowa during the winter.
7. Snowy Owl
- Scientific name: Bubo scandiacus
- Size: 20.5-28 inches long
- Weight: 56.5-104 ounces
- Wingspan: 49.5-57 inches
Snowy owls are striking birds. The males are mostly white with bright, cat-like yellow eyes. The females and immature birds have dark brown or black spots. The males become whiter as they age.
Snowy owls live in the Arctic Circle, where they hunt for mammals such as lemming and ptarmigans during the long summer days. They travel south to Canada, Alaska, and the very northern parts of the US during the winter months.
Most of the time, you can see them sitting on the ground near their hunting areas. They’ll also perch on power or telephone poles, fences, hay bales, and abandoned structures. They fly low to the ground as they scan the tundra or fields where they hunt.
In Iowa, you may rarely see these birds all across the state if food is scarce in their normal range.
The snowy owl is a rare bird to see, especially because their populations are declining.
8. Burrowing Owl
- Scientific name: Athene cunicularia
- Size: 7.5-9.8inches long
- Weight: 5.3 ounces
- Wingspan: 21.5 inches
Most owls live in the trees or shrubs, but burrowing owls have long legs to run along the ground in prairies, deserts, and grasslands. They hunt for rodents and then live in tunnels that animals have abandoned, like ground squirrels and prairie dogs.
They’ll even hunt small rodents and then take over their burrows. If that’s not available, they’ll live in pipes or tubing.
They’ve adapted to life underground by developing a high tolerance for carbon dioxide, which builds up in underground spaces.
Look for long-legged owls with mottled brown coloring and bright yellow eyes to identify them. They have flat heads.
Burrowing owls live in Iowa only during the summer, so be ready during that time of year to find these raptors.
9. Eastern Screech Owl
- Scientific name: Megascops asio
- Size: 6.3-9.8 inches long
- Weight: 4.3-8.6 ounces
- Wingspan: 18.9-24.0 inches
The eastern screech owl is related to the western screech owl, as you might expect. This owl lives on the east side of the Rocky Mountains, with a little overlap in the Rocky Mountains between their western cousin.
In Iowa, you can find them across the state all year long.
Eastern screech owls are excellent hiders. Their gray or reddish-brown mottling makes them blend right into the bark of the trees where they like to perch and nest. In fact, you might not even notice them until you see their bright yellow eyes shining.
They have distinct ear tufts and a yellow beak, with a dark V between their eyes.
These owls are night hunters, which makes them even more of a challenge to see. Your best bet is to listen for the whining trill call that they make and then keep your eyes peeled.
If you’re not big on bird-watching at night, look at the cavities of trees as you walk around their native range. You should be able to see them as they sleep the day away.
