I’ve always been fascinated by the diverse wildlife found in Iowa, but there’s one creature that’s captured my interest more than others – the owl. These nocturnal birds of prey are as mysterious as they’re captivating, and Iowa’s rich landscape provides the perfect habitat.

In the heartland of America, Iowa’s prairies, woodlands, and wetlands are home to several species of owls. From the large, striking Great Horned Owl to the smaller, elusive Eastern Screech Owl, these birds are an integral part of the state’s ecosystem.

Join me as we delve into the world of Iowa’s owls, exploring their habitats, behaviors, and the conservation efforts in place to protect them. It’s a journey that’s sure to enlighten and inspire, whether you’re a seasoned birder or just a casual nature enthusiast.

The Diversity of Iowa’s Owls

Iowa’s rich ecology allows for a broad spectrum of fauna, among which the wondrous owls hold my particular interest. They are some of the most captivating creatures with their enigmatic presence and secretive nature.

There’s an impressive range of owl species that call Iowa their home. From the powerful Great Horned Owl to the smaller yet fascinating Eastern Screech Owl, each has its unique appeal.

Think of the Great Horned Owl, a robust bird standing tall with its striking, erect ear tufts. These expansive raptors are dominating the bushland, pastureland, and even suburban landscapes in Iowan nights. They are undeniably the most widely spread across the State.

Flipping the size coin, we find the Eastern Screech Owl. This little surprise package might not be as large and imposing as its bigger cousins, but the sound it creates echoes through the night with chilling clarity. Don’t be mistaken by its size; it’s a capable predator adept at stealth hunting.

Between these two extremes, there are several species like the Barred Owl and the Barn Owl. The Barred Owl, with its striking eyes and distinctive hooting, often make their presence felt in the deep woodlands. And then there’s the Barn Owl, whose distinctive heart-shaped face and white underbelly are unforgettable. They are the favourites of barn owners as they keep the mice population in check.

But wait! Before we move on, we mustn’t forget the Snowy Owl, an infrequent visitor that creates a wave of excitement with its rare appearances.

To say that this overview covers all information about the owl diversity in Iowa would be an exaggeration. Iowa’s land is replete with other notable species such as the Northern Saw-whet Owl, Long-eared Owl, and the Short-eared Owl. With behavioral patterns as interesting as their names, they collectively add to the fascinating world of owl watching in Iowa.

Now that we have a brief understanding of the various owl residents in Iowa, let’s explore their habitats, behaviours, and their roles in our natural world.

Habitats of Iowa’s Owls

Let’s take a trip across Iowa and discover the diverse habitats that our featured owls call home.

The Great Horned Owl is quite versatile with its living spaces. It’s just as comfortable in the tree-lined forests as it is in the city’s parks. Their ability to adapt and thrive in various landscapes makes them one of the most common owl species in Iowa.

On the other hand, Eastern Screech Owls prefer well-established areas with sturdy old trees. They often make tree cavities their home, providing a secure and sheltered environment for raising their chicks.

The Barred Owls, known for their unique “who cooks for you” vocalization, are inhabitants of old mature forests. Their affinity for water bodies is undeniable, with an inclination towards riparian woods—woodlands near the water—where their primary prey thrives.

Barn Owls, earning their name for their preference of barns and other human structures, occupy open grasslands, farmlands, and marshes. These owls are partial to areas flush with small mammals—main food source.

Trusting the frigid beauty of the winter season, the Snowy Owl visits Iowa. Snow covered open fields, farmlands, and even airports provide an excellent habitat for these seasonal guests as their white plumage allows them to blend seamlessly with the snow covered landscape.

Northern Saw-whet Owls and Long-eared Owls, primarily nocturnal species, curate their own private spaces amid dense coniferous forests. The secluded and quiet nature of these habitats renders them the perfect nesting grounds for these species.

Hovering over open fields and grasslands at dusk and dawn, Short-eared Owls grace the lands of Iowa. Their peculiar choice of ground nesting sets them apart as distinct and gives open landscapes a magical and evocative feel.

As we journey across the landscapes, bearing witness to these mesmerizing habitats, we’re drawn further into the lives of these wonderful creatures.

Behaviors of Iowa’s Owls

As we journey further into the thrilling world of Iowa’s owls, I’d like to focus on their behaviors, which are as captivating as their habitat preferences.

What fascinates me most about Great Horned Owls may surprise you. These versatile residents of Iowa forests and fields are known to be highly adaptable, but it’s their nocturnal hunting behavior that truly stands out. You’ll find them hunting from dusk till dawn, seeking out a broad range of prey – from rodents to reptiles.

The night is also alive with the call of the Eastern Screech Owls. Primarily insectivores, they stake out their territory by giving unique, haunting trills. When it comes to nesting, they’re not builders but opportunists, adopting cavities left by other species.

Barred Owls, on the other hand, have a preference for riparian woods and call out to their kind with a distinct “who-cooks-for-you” call. Unlike the Eastern Screech Owls, the Barred Owls are also known to hunt during daylight hours, particularly during the breeding season. Another surprising trait is their adaptability to suburban environments.

The Barn Owls, named so owing to their nesting habits in old barns or other manmade structures, are silent hunters who depend on open grasslands for their diet of voles and other small mammals. It’s fascinating to observe how silently they swoop in on their prey.

The solitary Snowy Owls, who visit our state during the winter months, have adapted to hunting in snow-covered open areas. You’ll find that these owls have no fear of human beings and have even been observed in airport areas.

In contrast, the secretive Northern Saw-whet Owls and Long-eared Owls prefer secluded coniferous forests. They have rather cryptic lifestyles, opting to stay hidden during the day and venturing out to hunt under the cover of darkness.

Lastly, it’s the Short-eared Owls with their ground nesting behaviors that truly set them apart. Their flights are characterized by irregular, moth-like wingbeats, making them a fascinating sight in Iowa’s open fields.

So, let’s continue exploring these captivating creatures and their intriguing behaviors as we delve further into the world of Iowa’s owls.

Conservation Efforts for Iowa’s Owls

Iowa’s owl populations have faced a multitude of threats over the years. Habitat loss, rodenticide poisoning, and disturbances to nesting areas are just a few of the challenges these captivating creatures face. Thankfully, wide-ranging efforts are underway to counter these threats and help bolster the owl populations in Iowa.

Organizations across the state are implementing conservation strategies to assist our nocturnal friends. For instance, the Iowa Raptor Project, dedicated to the rescue, rehabilitation, and research of birds of prey, conducts educational programs and promotes community involvement in conservation efforts. They have made significant strides in owl protection in our state.

Another significant contribution comes from local communities. Many communities in Iowa now have ‘Adopt an Owl’ programs. These initiatives provide funding for owl care and research, lending a hand to involved organizations.

Significant work is also being done to address habitat loss, a major concern for owls. Conservation efforts mainly involve preserving existing habitats and creating new ones where necessary. For example, stands of mature trees are being protected, and nest boxes are being provided in suburban areas to accommodate the Barred and Screech Owls.

Each effort, big or small, contributes to the preservation of our fascinating owl species in Iowa. Remember, it’s our shared world and every creature, including Iowa’s distinct owls, holds a special place within it.


I’ve taken you on a journey through the world of Iowa’s owls, shedding light on the challenges they face and the efforts being made to protect them. It’s clear that organizations like the Iowa Raptor Project are making strides in educating the public and fostering a sense of responsibility within our community. We’ve learned that our actions, like choosing not to use rodenticides and getting involved in local conservation programs, can have a significant effect on these majestic birds’ survival. So, let’s take what we’ve learned and apply it. Let’s be mindful of our choices and their impact on Iowa’s owls. After all, it’s up to us to ensure their hoots continue to echo through our night skies.
