11 Things (2023) You Have to Know


You may have seen some of the more common types of owls, such as the barn owl and short-eared owl, but only the lucky ones have had the chance to be in the presence of North America’s rarest owl: the Spotted Owl.

This species is endangered and has been the focal point of controversy in regard to land management and conservation efforts.

In the 1980s and 90s, a heated debate ensued as environmentalists fought to have the owl listed as an endangered species.

The fight ended in favor of the bird, and it was an important step forward for wildlife conservation.

So, what makes the spotted owl so special, and why did it spark so much controversy?

This article is going to be your guide to the spotted owl, covering everything from its behavior to its habitat preferences to the importance it has had in environmental decisions.

And if you’re lucky enough to live near this rare species, spotting these animals is a wonderful sign that the surrounding ecosystem is healthy and thriving.

1. What Does the Spotted Owl Look Like?

The spotted owl is a medium-sized owl, around 1.5 ft tall, that’s dark brown with white dashes on its breast, wings, and head.

It has a prominent brown facial disk that’s lighter than the rest of its body and dark brown eyes.

Males and females have similar plumage, but the females can weigh as much as 20% more than the males.

The average weight and wingspan of the species are 1 to 1.5 lbs. and 3.5 feet.

People often mistake the barred owl for the spotted owl.

The two species share similar features; however, the barred owl is a lighter brown with large streaks of white on its breast and has a more prominent facial disk that’s also lighter in color.

To make matters a bit more complicated, the two types of owls sometimes share the same territories.

So, let’s check out where the species is primarily spotted–no pun intended.

2. Where Does the Spotted Owl Live?

In the United States, the northern spotted owl is found from western Washington down to the north-central coast of California (the Mexican spotted owl has been seen in parts of Arizona, New Mexico, Colorado, Utah, and Texas, and the California spotted owl is found sporadically in the central and southern part of the state).

Spotted owls live in mature forests and wooded canyons at low to moderate elevations.

Within their habitats, they use trees with broken tops, deformed limbs, and large holes as nesting sites.

Here are some of the trees that spotted owls prefer:

bulletPacific Silver Fir

bulletSitka Spruce



For the most part, these owls are permanent residents of their regions; however, those that live in mountainous areas will temporarily vacation down to lower elevations during the winter to escape harsh temperatures.

There are some owls, such as the short-eared owl, that do migrate long distances in the winter, but the spotted owl does not fall into this group.

3. How Long Do Spotted Owls Live?

On average, the spotted owl lives between 10 and 15 years.

The species’ lifespan greatly depends on the specific region in which individual owls live.

Their living in environments that are being negatively impacted by human activity will have a significantly lower lifespan than those living in healthy, secure environments.

In favorable conditions, when threats are minimal and food is plentiful, there have been cases of these types of owls living for 20 years or more.

The oldest recorded spotted owl was found alive in 2006, and it was believed to be at least 21 years old.

Typically, owls have a longer lifespan when kept in captivity since they have consistent access to food, medical treatment, and zero threats from predators.

One of the longest-living owls is the great grey owl, which can live up to 40 years in captivity.

4. What is Threatening Their Habitat?

There are several factors that are threatening the spotted owl’s habitat.

Although there are conservation efforts to reduce these threats, the species is still extremely vulnerable.

Here are the main threats to their habitat:


Logging and deforestation have been a primary threat to spotted owls.

When timber companies clear out massive areas of old-growth trees, it destroys the owls’ habitat, causing them to struggle to find new nesting sites and food sources.

Logging activity is what originally sparked environmentalists to fight for spotted owls to become an endangered species, initiating years of controversy.


Urban development leads to habitat fragmentation, causing ideal living areas for spotted owls to become smaller and smaller.

Fragmented habitats lead to fewer food sources, reduced genetic diversity, and fewer nesting sites.

In some cases, the land can be restored; however, when large pieces of infrastructure divide natural territories, restoration is impossible.

bulletClimate Change

Recent changes in temperatures, rainfall frequency, and rates of wildfires are disruptive to spotted owls’ habitats.

Climate change is making forest ecosystems less suitable for the species, which is resulting in a decrease in the population.

bulletInvasive Species

Factors like climate change, deforestation, and fragmentation have caused competing species to enter the territory of this bird.

There’s now greater competition for resources and nesting sites.

One of the species that has become the most problematic for the spotted owl is the barred owl, which is negatively impacting rates of reproduction.

5. Are Spotted Owls Endangered?

Spotted owls are an endangered species.

The title was awarded after a long environmental battle.

All three subspecies, the northern spotted owl, Mexican spotted owl, and California spotted owl, are all considered to be endangered.

Spotted owls were awarded the endangered title due to the loss and degradation of their habitats and the increased competition due to barred owls.

Although the species now receives special attention and protection, the population is still declining each year.

There have been reports stating the population of the northern spotted owl is declining at a rate of 2.9 percent.

The idea of large amounts of spotted owls disappearing from habitats in the Pacific Northwest is becoming closer to reality if drastic changes aren’t made.

In addition to being an endangered species, these birds are also referred to as an indicator species.

Indicator species refer to animals that show positive or negative signs of the ecological health of the habitat.

If spotted owls are able to survive and thrive in a certain area, it tells us that the ecosystem is well-balanced.

6. What Was the Controversy Over the Northern Spotted Owl?

The northern spotted owl was the center of environmental controversy in the late 1980s and early 1990s.

What set the stage for the controversy were the new environmental protection laws passed in the 1970s, such as the National Environmental Policy Act (1970), the Endangered Species Act (1973), and the National Forest Management Act (1976).

In the 1980s, new scientific research concluded that the spotted owl required large pieces of mature forests to prosper, and the massive amount of trees being cut for timber sales was threatening the species.

Despite the new environmental legislation, federal agencies like the Forest Service and the Fish and Wildlife Service were doing little to nothing to protect the land and the spotted owl.

It wasn’t until Judge William L. Dwyer, who served Seattle’s federal district court, took steps to delay a majority of the pending timber sales that things began to change.

For the next years, he was one of the leading voices that challenged and chastised the federal agencies for refusing to comply with environmental laws.

Eventually, the Fish and Wildlife Service categorized the spotted owl as an endangered species.

Slowly but surely, as the public protested and more judges shined a light on government failures, real changes were made.

The main argument against the new environmental laws was that they would take away thousands of jobs in the timber industry.

However, the actual number of jobs lost was a fraction of what the timber industry had claimed would occur.

7. How Do Spotted Owls Hunt for Prey?

Most species of owls are nocturnal hunters, and the spotted owl is no different.

The owl uses a sit-and-wait approach to hunt its prey.

From a perch, it will wait for small mammals, birds, and insects (insects are typically reserved for when food sources are scarce) to come into range and swoop down, grabbing and killing it with its talons and beak.

Here’s a list of the animals in its diet:











The spotted owl is a skilled hunter thanks to its incredibly sensitive hearing and ability to fly silently.

But the owl needs prey to hunt.

As logging, climate change, and invasive species reduce the number of resources in their territory, spotted owls have to work harder and go longer periods of time without access to food.

8. What Are Their Main Predators?

The spotted owl is a master of stealth, but it still has a few predators to look out for.

Here are its main predators:

bulletGreat Horned Owls

bulletNorthern Goshawks

bullet*Occasionally, other animals, such as bobcats, foxes, and coyotes.

The spotted owl has such few predators because of its ability to camouflage with its surroundings, nocturnal patterns, size, and lethal talons.

Although the barred owl doesn’t hunt the spotted owl, it’s arguably the biggest threat to the species.

Due to the barred owl expanding its range because of climate change and deforestation, it’s inadvertently killing more spotted owls than predators by taking resources and nesting sites.

Conservation efforts are in the works to reduce the impact of barred owls; however, competition for resources continues to grow, and the population size of the spotted owl continues to decline.

9. What is the Role of the Species in the Ecosystem?

Without the spotted owl, ecosystems fall out of balance.

The spotted owl plays an important role in monitoring the population sizes of rodents and other small animals.

When the populations of rodents and small animals get too large, they will destroy plants and crops that are crucial food sources for other creatures.

Because the spotted owl depends on healthy, robust forested areas, their presence is a great indicator that the ecosystems are thriving.

When fewer and fewer are spotted in the area, it’s a sign that there’s trouble in the ecosystem, whether it be due to logging, fragmentation, climate change, or invasive species.

10. How Do Spotted Owls Communicate?

Spotted owls communicate through various sounds and body gestures.

The sounds the species make are categorized as hoots, whistles, chitters, and barks.

Depending on the situation, it will make specific sounds.

For example, the owl will make a long series of four-note hoots when defending its territory.

Spotted owls in areas with dense foliage typically have more refined vocalization abilities.

Also, the species’ hooting patterns differ from other species, allowing them to identify their mates and family members.

In addition to vocalizations, they also use body gestures to express different messages.

If a spotted owl is tilting or bobbing its head, it is an indicator of curiosity.

It may also use prolonged eye contact or fluffed feathers to convey dominance or aggression.

Vocalizations and body gestures are very important for the species’ ability to establish and defend territories and attract mates.

Depending on the region, communication styles will vary from group to group.

11. Can Spotted Owls Be Kept as Pets?

In the United States, it is illegal to keep native owls as pets.

The spotted owl is a wild bird that requires a specific diet, living conditions, and medical care.

Additionally, these owls have dangerous talons and beaks that could cause serious injuries if they are improperly handled.

Because the owl is protected by law, a person could face legal punishment for capturing, possessing, or trading it.

Only trained, licensed professionals are allowed to possess one as it’s being rehabilitated or used in a breeding program or for educational purposes.

Just because spotted owls can’t be kept as pets doesn’t mean you can’t enjoy their beauty and rarity.

The best way to enjoy these creatures is by visiting their natural habitats and local wildlife rehabilitation centers or other wildlife organizations–these facilities will let you get as close as possible to the owl without putting yourself or the bird in danger.

Final Thoughts

The spotted owl is an incredible species that has played an important role in changing the landscape of environmental protection.

Of the 19 owl species in the United States, this one is by far the rarest, and viewing one is not an event to take for granted.

Despite their incredible hunting and adaptation abilities, the owl is still under threat.

Factors such as logging, fragmentation, deforestation, invasive species, and climate change are causing the population to decline year after year.

Although conservation efforts are being made, we may live in a future where the spotted owl becomes extinct.

So, do what you can to help preserve the animal so that habitats can thrive and the bird can continue to grace the skies.
