You will see all of the owl species that can be found in Iowa. Some of them are more difficult to find than others, so will you be lucky enough to find them all?

Iowa has nine different species that call our state home, whether full-time or part-time, and you can find them in a number of different habitats.

For the best chance of seeing owls in Iowa, go to a wooded area at dawn or dusk. Consider high vantage points on the forest’s edge that overlook open grassland or pastures.

Eight Owls Species in Iowa:

  • Barn Owl
  • Eastern-screech Owl
  • Great Horned Owl
  • Snowy Owl
  • Barred Owl
  • Long-eared Owl
  • Short-eared Owl
  • Northern Saw-whet Owl

The Great Horned Owl is the largest owl in Iowa, and the Northern Saw-whet Owl is the smallest. Owls are predatory birds that hunt and consume small mammals, as well as snakes, frogs, and insects.

Owls consume their prey whole, frequently after removing the head, and regurgitate the bones and fur. For the best chance of seeing owls in Iowa, go to a wooded area at dawn or dusk. Consider high vantage points on the forest’s edge that overlook open grassland or pastures.

8 Species of Owl in Iowa

1. Barn Owl

The Barn Owl can be seen in Iowa all year, but it is not very common. This silent nocturnal bird with a white face is about the size of a crow.

  • Length: 12.6-15.8 in (32-40 cm)
  • Weight: 14.1-24.7 oz (400-700 g)
  • Wingspan: 39.4-49.2 in (100-125 cm)

Bar Owl

Barn owls have buff-colored backs and white faces, chest, and belly, as well as underwings. Their faces are round, and they have long, rounded wings and short tails.

Females have parasite-repelling spots on their chests, and the greater the number of spots on the female’s chest, the greater the amount of contribution the male makes to the construction of the nest!

It is believed that they search for tiny rodents across open ground at night, such as fields and meadows, and that their name comes from the fact that they frequently roost in barns during the day.

Barn owls eat their food whole and cough up pellets twice a day, according to the National Wildlife Federation. As with all animals examined, the Barn Owl hunts for prey largely by sound because it has the finest hearing of any species.

These abilities enable them to hunt down and capture prey in full darkness, including those hiding beneath plants or in a show. They construct their nests in tree cavities, caves, and, more frequently, in barns or other abandoned or silent structures, according to the National Wildlife Federation.

The nest is formed of regurgitated pellets that have been organized into a cup by their feet and placed inside a cup. They lay between 2 and 18 white eggs throughout the course of 1 to 3 broods.

Approximately 46 species of Barn Owls may be found throughout the world, and they can be found on all six continents. Instead of hooting like other owls, they make a scratchy scream call that is difficult to understand.

2. Eastern Screech Owl

The Eastern Screech-Owl can be seen in Iowa all year and is common east of the Rockies.

  • Length: 6.3-9.8 in (16-25 cm)
  • Weight: 4.3-8.6 oz (121-244 g)
  • Wingspan: 18.9-24.0 in (48-61 cm)

Eastern Screech Owl

Gray and red are the colors of this short, stocky bird. A robin’s size is comparable to that of a crow, but they are more bulkier, with a large head and little neck. As a result of their camouflage patterns and spots, they are difficult to distinguish against tree bark.

When looking for the Eastern Screech-Owl, look for it in woodlands and parks, where you may be able to notice it sunning itself in a tree cavity on cold sunny days, or by the flurry of songbirds that flock to them when they discover them.

Another telltale sign is a collection of pellets on the ground. They can be identified by their harsh, descending whinny sound and vibrating trill. Eastern Screech-Owls prey on a wide variety of tiny animals, including birds, mammals, insects, reptiles, and amphibians.

They hunt primarily at night, although they also hunt at dawn and twilight, and they are nocturnal. They typically sit on perches and wait for prey to pass by before leaping to their death from them.

Given that they are unable to excavate their own nests, the Eastern Screech-Owl typically makes use of abandoned woodpecker nests as well as other holes and cavities. Their eggs are laid on whatever trash available at the bottom of the cavity because they do not employ nesting material. They lay between 2 and 6 white eggs every time they lay an egg.

3. Great Horned Owl

Throughout the year, the Great Horned Owl can be seen in Iowa and throughout North America, including Canada. They are large owls with thick bodies and large tufts of hair on their heads that resemble ears.

  • Length: 18.1-24.8 in (46-63 cm) 
  • Weight: 32.1-88.2 oz (910-2500 g)
  • Wingspan: 39.8-57.1 in (101-145 cm)

Great Horned Owl

In appearance, the Great Horned Owl is a grey-brown bird with a mottled pattern and a white patch on its throat. A deep hooting call can be heard from their nest. Their wings are large and rounded.

One of the most common owls in North America, the Great Horned Owl can be found in a range of environments, including woods, deserts, urban areas, and grasslands, among others. These ferocious hunters feed on birds and mammals that are far greater in size than they are.

They are not picky eaters and will eat practically everything you put in front of them! When building their nests in trees, Great Horned Owls frequently re-use old nests that were previously used by another species.

Occasionally, they will line the nest with bark, leaves, downy feathers, or pellets, although they will also leave the nest unlined on occasion. They lay anything from one to four white eggs.

4. Snowy Owl

However, they are only found in Iowa during the winter months because it is the southernmost point of their winter range. They are white birds with modest amounts of black or brown patterns, yellow eyes, and are around the size of a crow in terms of size and appearance.

  • Length: 20.5-27.9 in (52-71 cm)
  • Weight: 56.4-104.1 oz (1600-2950 g)
  • Wingspan: 49.6-57.1 in (126-145 cm)

Snowy Owl

Even against a snowy backdrop, they can be difficult to notice, but they prefer to sit on high ground, which makes them easier to locate. They are normally deafeningly quiet, but during the breeding season they may emit a harsh croak or shrill whistle to attract mates.

Where Do Owls Nest? Everything You Need To Know

Snowy Owls, in contrast to other owls, are diurnal, meaning they hunt in the arctic during the entire 24-hour summer daylight period. They prey on small mammals, primarily lemmings, and can ingest as many as 1600 of them in a single year, according to some estimates.

It is also possible to catch flying birds such as ptarmigan and ducks. During the winter, they will prey on rodents, rabbits, squirrels, and birds such as ducks and geese, among other things.

The Snowy Owl’s nest is merely a shallow depression in the tundra that has been scratched out by the animal.

They seek a windswept ridge that will be blown clear of snow, and they keep the nest for many years until discarding it altogether. They lay anything from 3 to 11 white eggs per clutch.

5. The Barred Owl

The Barred Owl can be found in Iowa all year. These large, stocky birds are roughly the size of a crow or a goose.

  • Length: 16.9-19.7 in (43-50 cm)
  • Weight: 16.6-37.0 oz (470-1050 g)
  • Wingspan: 39.0-43.3 in (99-110 cm)

Barred Owl

Barred Owls are brown and white in color, with a mottled pattern of vertical stripes on the belly and horizontal stripes on the back and upper chest. They have black eyes, a round head with no ear tufts, and a rounded tail.

This species prefers to reside in vast, mature forests, frequently near bodies of water, and lays 1-5 white eggs in tree cavities.

6. Long-eared Owl

The Long-eared Owl can be found throughout the year in Iowa, although after breeding, it may travel further south from the state’s northernmost reaches after breeding. They are medium-sized, slender owls, about the size of a crow, and they have a shocked expression on their faces when they see you.

  • Length: 13.8-15.8 in (35-40 cm)
  • Weight: 7.8-15.3 oz (220-435 g)
  • Wingspan: 35.4-39.4 in (90-100 cm)

Long-eared Owl

Long-eared Owls have patterned black and brown feathers, buff faces, big black or buff ear tufts, and yellow eyes. Long-eared Owls are found in the northern hemisphere.

Among the tiny mammals that Long-eared Owls eat are voles, mice, juvenile rats, and rabbits, among other things. They hunt over broad grassland or pastures by hovering only a few feet above the ground and listening for movement or looking for it with their eyes and ears.

They lay between 2 and 10 white eggs in stick nests that have been abandoned by other animals.

Long-eared Owls are rarely heard, with the exception of during the nesting season. Hoots and whistles at low pitches, as well as shrieks, screams, and meows that sound like cats, are all produced by them.

7. Short-eared Owl

Following breeding, the Short-eared Owl can be located in Iowa throughout the winter months, having migrated from northern states and Canada during the breeding season. They are around the size of a crow and have ear tufts that are relatively little in comparison.

  • Length: 13.4-16.9 in (34-43 cm)
  • Weight: 7.3-16.8 oz (206-475 g)
  • Wingspan: 33.5-40.5 in (85-103 cm)

Short-eared Owls

Short-eared Owls have mottled black, brown, and white coloring, a pale face, and yellow eyes with a black rim that are rimmed with black. Their wings are large and rounded, and they have a short tail.

Short-eared Owls are also one of a kind in that they build their own nests by scraping the ground into a bowl and lining it with grass and soft feathers, which is a first for the species. They lay between one and eleven cream or white eggs per clutch.

They are not extremely noisy, although the males will produce approximately a dozen hoots during courtship, and when protecting the nest, they may bark, whine, or scream. They are nocturnal, but they are active throughout the day.

8. Northern saw-whet Owl

The Northern Saw-whet Owl can be seen in Iowa all year. This tiny owl is roughly the size of a robin.

  • Length: 7.1-8.3 in (18-21 cm)
  • Weight: 2.3-5.3 oz (65-151 g)
  • Wingspan: 16.5-18.9 in (42-48 cm)

Northern Saw-whet Owl

Northern-Saw-whet Owls are distinguished by their small bodies and spherical heads. They have a mottled brown body with white spots, a white face with spots, a spotted head with spots, and yellow eyes.

These nocturnal hunters prey on tiny mammals, notably mice, in dense forest environments. It is common for them to construct their nests in tree cavities left by other species, such as Pileated Woodpeckers.

Their eggs are laid directly on the trash rather than on any other type of nesting material used by them. They lay between 4 and 7 white eggs every time they lay an egg.
