Barn Owls are medium sized owls with pale buff and grey feathers on both the head and their wings.

During the daytime these colours are more noticeable whilst at night and in certain types of light they can appear completely white.

These birds will occasionally stray into southern Canada and can be seen in 48 different states.

You are most likely to see these owls in open country such as grasslands.

These birds are monogamous, and many barn owls appear to mate for life, although there have been some conflicting reports that say males will mate with multiple females.

Males will bring food to the females as she gets the nest ready for incubation. These birds are protective of their nests, but they happily share hunting grounds with others of their species.

With their wide range across the states it is no surprise that the barn owl can be seen in all regions of the state throughout the year.

Most of the recorded sightings of this bird are in the north west of the state and the fewest are in the central regions.

Rats, Squirrels, Rabbits & Skunks

These birds are very similar in appearance to the Western Screech-Owl, both use their varying grey feathers to camouflage against trees.

These short and stocky owls will form breeding pairs and will help raise young together.

However, some males have been noted to mate with two females throughout the breeding season and they are not believed to form long term breeding pairs.

Males will feed females and their young when they first hatch and spend most of their time defending the nest.

You are most likely to see these birds in dense forests and they have been known to use manmade bird boxes. They have also been known to nest and breed successfully in city parks and farmlands.

The Eastern Screech owl has a range that encompasses the eastern states and they can be seen in Iowa throughout the year.

They can be seen in all regions of the state with most of the sightings being recorded in the north western areas.

Squirrels, Rabbits & Skunks

These large owls get their names from their long, pointed ear that look like horns on top of their heads.

They have large stocky bodies with brown and grey feathers. These birds are monogamous and form long term breeding pairs, the breeding pairs have been known to stay with each other outside of the breeding season.

They are territorial birds and have a series of hoots that they will use to defend their territory, both members of the breeding pair will help defend their nests and females tend to be more aggressive than males during the breeding season.

In fact, these birds are so territorial that they have at times been known to kill other individuals of their own species that stray too close to their territory.

They are often harassed by other species of birds such as crows which will call and peck at them to try and get them to abandon the area and their eggs.

As one of the widest spread and most abundant species of owl their range includes all of Iowa and they are year-round residents in the state.

Most of the recorded sightings of this bird have been in the western half of the state.

The Northern Saw-whet Owl is a small species of owl that is covered in dark brown feathers.

These roost throughout the day like most owls and nest in various forests.

Whilst these birds are primarily monogamous, there have been instances of males mating with multiple females during the breeding season.

You will hear their distinct too-too-too mating call from January to March which is the beginning of the breeding season.

When a female enters a male’s territory, he will circle around her in flight 20 times before moving down to her and gifting her with a prey item.

They pair with new mates each year although some breeding pairs will stay with each other to defend their territory outside of the breeding season.

These birds are often preyed upon by larger species of owls.

These birds can be seen throughout the state of Iowa but only outside of their breeding seasons and most commonly in the winter months.

Most of the recorded sightings of this bird have been in the central regions of the state with very few being recorded in the far south of the state.

Short-eared owls form loose colonies and are monogamous maters during the breeding season.

The individuals in the colonies will roost about 50ft away from one another.

It is unknown as to whether they mate for life. Short-eared owls only tend to make their nests in trees during the winter months when it becomes snowy.

They will make their nests close to the ground during the breeding seasons.

Males will feed the females whilst they are incubating the eggs and will also help defend their territory with a series of harsh calls.

The Snowy Owl is a large species of owl that is covered in thick white feathers that have tiny grey markings on their tips.

These markings differ between each individual. It is not confirmed whether these birds are monogamous, but it is known that males exhibit a unique flight display when courting a female.

They will grasp some prey, such as a lemming, in their talons before performing a very large dive with their wings in a v shape.

Snowy owls are incredibly aggressive and whilst they are happy to share hunting grounds, they are not happy sharing territories.

There has even been a reported incident of a snowy owl attacking a pair of arctic wolves.

Snowy Owls like wide open spaces with a minimal number of trees, they are most commonly found in tundra habitats and across plains.

They will also perch of high man-made items such as telephone poles during the winter months. This is so that they can observe prey more clearly.

Snowy Owls have a limited range in the United States, but they can be seen in the state of Iowa during the winter months.

There have been sightings of this bird across the state but most of the sightings occur in the northern regions of Iowa.

Their bodies are covered with black and brown feathers and their faces are orange.

These owls like to roost in dense woodlands and outside of the breeding season will roost in loose colonies of up to 100 individuals.

These colonies stay together for most of the year and even in the breeding season they will nest near each other, but they will not roost together.

These birds are monogamous, only mating with one individual during the breeding season, although it is not believed that they form long term breeding pairs.

Males will court the females by performing a series of complex, zigzag flights whilst producing a mating call.

Burrowing Owls stay together in loose colonies and are monogamous during the breeding season, although it is unknown as to whether they form long lasting breeding pairs.

As you would likely expect from the name, these owls do make small burrows.
