A reader recently asked me about five birds he had seen over the sounds of Surf City last weekend. He was convinced they were five different kinds of “sea hawks.”

At first glance, it was an understandable conclusion.

Each bird was large. Each spent time soaring overhead or hesitating up high over the water. Each occupied the same stretch of coastal North Carolina sky.

Yet every photograph and description reflected the same species: an osprey.

Distance has a way of simplifying wildlife. Colors disappear. Markings fade. Details are lost. What remains is a silhouette against the sky.

Most of us learn to recognize birds by their appearance. Raptors are often easier to understand by their behavior.

• What is the bird doing?
• Is it hovering over the water?
• Circling without flapping?
• Perched motionless on a fence post?
• Drifting above a marsh?
• Crossing silently through the trees after sunset?

The answer often reveals more than the feathers.

The skies above Onslow County are shared by a community of predators. Some hunt fish. Some hunt rodents. Some hunt insects. Some hunt other birds. Some hunt only at night. Others serve as nature’s cleanup crew.

At a distance they may look similar.

Spend enough time watching them, however, and the differences become impossible to miss.

Following the Fish

Osprey: The Fisherman

If there is a signature bird of the coast, it may be the osprey (Pandion haliaetus).

You notice one long before you identify it. The bird appears above a creek, river, or stretch of open water, turns into the wind, and suddenly seems to stop moving. For a few seconds it hangs there, suspended above the surface before plunging feet-first toward the water below.

That moment of hesitation is not hesitation at all.

The bird is making a final decision.

Water distorts light. Fish change direction. Wind roughens the surface. What appears obvious from a dock or kayak becomes much more complicated from above. The osprey’s brief hover allows it to judge distance, depth, and movement before committing to the dive (Poole, 1989; Bierregaard et al., 2020).

The splash usually draws everyone’s attention.

The fish often draws the next question.

Watch an osprey leave the water carrying a mullet or menhaden and it is difficult not to wonder how the bird manages to hold onto it. Fish are essentially living bars of soap wrapped in muscle, built to slip through water and escape predators. Osprey solve that problem with feet lined by tiny backward-facing spicules and a reversible outer toe that help secure slippery prey (Poole, 1989; Bierregaard et al., 2020).

Then, almost as soon as the bird becomes airborne, something else happens.

The fish turns.

Within seconds the osprey has repositioned its catch so the fish faces forward. What looks like a small adjustment saves energy over the course of the flight. A fish carried sideways catches air. A fish carried headfirst moves through it. Often the bird gives its catch a vigorous shake as it climbs away from the water, shedding excess water before continuing on its way. Together, these adjustments reduce drag and make transporting a heavy, slippery meal through the air more efficient (Allen et al., 2018; Poole, 1989; Bierregaard et al., 2020).

Around nesting season, however, it is often the noise rather than the fishing that gets people’s attention.

Osprey rarely seem quiet.

Calls echo from nesting platforms, channel markers, dead trees, and utility poles throughout the breeding season. Adults announce arrivals. Mates communicate with one another. Young birds call constantly whenever food appears nearby. What sounds chaotic from a distance is often a family carrying on a conversation (Bierregaard et al., 2020).

By late summer, that family becomes easier to see.

Several birds may gather near a nest, perched along the same stretch of water where they have spent months raising young. Then, without warning, they take to the air together. The younger birds follow the adults across creeks, marshes, and open water, practicing turns, landings, and the flight skills that will eventually carry them south. What appears at first to be a loose gathering of osprey is often a family still learning from one another long after the young birds have left the nest (Poole, 1989; Bierregaard et al., 2020).

The nests themselves remain long after the birds have departed.

Many osprey return to the same sites year after year, adding sticks, repairing damage, and expanding structures that can eventually become enormous. What begins as a modest nest slowly grows into a landmark visible from hundreds of yards away (Poole, 1989; Bierregaard et al., 2020).

For many coastal residents, those nests become part of the landscape.

And when spring returns, so do the birds that built them.

Bald Eagle: The Opportunist

If you spend enough time around the water, eventually you’ll see it happen.

An osprey leaves the surface carrying a fish. For a few moments, everything appears normal. Then a second bird enters the scene.

Larger.

Heavier.

Built on an entirely different scale.

The bald eagle (Haliaeetus leucocephalus) begins to follow.

What started as a successful fishing trip suddenly becomes a chase.

From below, the interaction can look almost personal. The osprey twists and climbs. The eagle closes the distance. Sometimes the osprey escapes. Sometimes it drops the fish. The eagle wheels downward after the falling meal while the osprey continues on empty-taloned.

Why go through all that trouble?

Because catching a fish requires energy.

An osprey may spend considerable time searching the water, hovering above the surface, adjusting for currents, and committing to a dive before finally securing a meal. An eagle watching from a nearby perch can recognize that success immediately. From the eagle’s perspective, the fish has already been found. The difficult part of the hunt is over (Buehler, 2020).

This often leads people to wonder whether bald eagles are better fishermen than osprey.

The answer depends on how you define fishing.

If the goal is catching fish, the osprey remains the specialist. Nearly every aspect of its anatomy is designed around that task. Its feet grip slippery prey with remarkable efficiency, and its entire hunting strategy revolves around locating fish beneath the water’s surface.

A bald eagle approaches the world differently.

Rather than specializing in a single food source, eagles take advantage of opportunities wherever they find them. Fish remain important, particularly along the New River, Stump Sound, the Intracoastal Waterway, and the countless creeks that thread through coastal marshes. Yet waterfowl, mammals, reptiles, and carrion can also become part of the menu (Buehler, 2020).

A closer look at their feet reveals those differences. Osprey feet are designed to hold fish. Eagle talons are designed to seize and restrain a wider variety of prey. One bird is built around precision. The other is built around versatility (Buehler, 2020).

That versatility helps explain why bald eagles have become increasingly common sights along the Onslow County coast. Open water, abundant prey, expansive marshes, and large trees provide everything they need. Whether soaring above an estuary, perched along a creek, or watching from a pine overlooking the water, eagles occupy a position near the top of the coastal food web (Buehler, 2020).

And every so often, that position allows them to let someone else do the fishing.

The Hunters of Marsh and Forest

Red-shouldered Hawk: The Watcher on the Fence

Not every raptor announces itself from the sky.

Some introduce themselves by showing up in the yard.

You glance out the window and notice a hawk perched on the fence. Hours later it seems to be in exactly the same place. The next morning it is back again.

Eventually curiosity takes over.

What is it watching?

Many people assume the hawk is focused on the house, the dog, or the family moving through the yard.

In reality, the bird is usually paying attention to everything else.

A well-maintained yard often provides excellent hunting habitat. Frogs move through flower beds. Lizards bask along retaining walls. Small snakes hunt beneath shrubs. Mice travel fence lines and wood piles. The red-shouldered hawk watches for movement, waiting for the landscape to reveal itself (Dykstra et al., 2020).

That patient approach reflects the habitats these birds prefer.

Unlike the open-country red-tailed hawk, red-shouldered hawks (Buteo lineatus) are closely tied to places where woods and water meet. Creek corridors, swamp edges, ponds, marshes, and bottomland forests provide the cover and diversity of prey they rely upon (Dykstra et al., 2020).

Along the coast, those habitats frequently overlap with where people live.

The fence post is simply the best seat in the house.

From there, the hawk can watch an entire ecosystem unfold beneath it.

Red-tailed Hawk: Master of the Open Sky

A red-tailed hawk (Buteo jamaicensis) – and my personal favorite bird – often attracts attention by doing remarkably little.

You notice one circling high above a field.

Several minutes later it is still there.

The wings barely move.

At first, most people wonder how the bird can remain in the air for so long without flapping. The answer lies in the atmosphere itself. As the ground warms, pockets of heated air rise into the sky. Red-tailed hawks locate these invisible thermals and circle within them, gaining altitude while expending very little energy (Kerlinger, 1989; Preston & Beane, 2024).

But staying aloft is only part of the story.

The real question is why the bird wants to be up there in the first place.

The answer becomes clearer when compared to the red-shouldered hawk.

A red-shouldered hawk often hunts by focusing on a particular place. A pond edge. A marsh creek. A backyard. It watches patiently from a perch, waiting for the landscape to reveal movement (Dykstra et al., 2020).

A red-tailed hawk takes the opposite approach.

Rather than concentrating on one corner of the landscape, it climbs high enough to see how all of those pieces connect. Fields blend into hedgerows. Roadsides meet forest edges. Open ground transitions into cover. From above, what appear to be separate places from the ground become a single hunting landscape.

That broader view is the red-tail’s specialty.

What appears to us as an empty field is filled with clues. A rabbit pauses along a fence line. A squirrel breaks from cover. A mouse rustles through the grass. The bird is not searching for a specific animal. It is searching for movement, patterns, and opportunities spread across hundreds of acres (Preston & Beane, 2024).

The thermal keeps the hawk aloft long enough to gather that information. Height becomes an advantage. Distance becomes information.

The bird is not circling because it has nowhere else to be.

It is circling because the sky offers the best view.

And from that vantage point, one movement in the wrong place at the wrong time is often all it takes.

Cooper’s Hawk: The Pursuit Hunter

If you maintain a bird feeder long enough, sooner or later the yard will go silent.

One moment cardinals, doves, and finches are moving between the feeder and nearby trees.

The next, everything disappears.

Then a gray blur streaks through the yard.

The first time you see it happen, it feels almost impossible that a bird that large could move that quickly through such a cluttered space.

Unlike the red-tailed hawk searching from hundreds of feet above the landscape or the red-shouldered hawk watching patiently from a perch, the Cooper’s hawk (Astur cooperii) hunts in motion. It is built for pursuit (Rosenfield et al., 2025).

Its long tail acts like a rudder while relatively short wings allow it to twist, turn, and accelerate through spaces that would seem impossible for most raptors. Branches, fences, shrubs, and backyard obstacles that slow other birds become part of the chase (Rosenfield et al., 2025).

That agility allows the hawk to exploit something many predators cannot.

Confusion.

A flock of birds startled into flight rarely moves in a straight line. Individuals scatter in different directions, darting through vegetation and searching for cover. The Cooper’s hawk follows.

What appears chaotic to us is a hunting opportunity to the hawk.

Yet not every backyard attracts a Cooper’s hawk.

If you’ve ever noticed that these birds seem more common in some neighborhoods than others, the surrounding landscape is often the reason. Cooper’s hawks favor places where trees, forest edges, wooded corridors, and open spaces meet. Those transitions provide both cover and opportunity, allowing the bird to move quickly between concealment and pursuit (Rosenfield et al., 2025).

A bird feeder placed within that landscape can become part of the story, not because the feeder attracts the hawk, but because it concentrates movement. Birds travel between the feeder and nearby cover. The hawk is already watching the area. The feeder simply makes activity easier to find.

Which is why the sudden silence is often the first clue.

Long before most people see the hawk, the birds have already noticed it.

For a few moments, the yard belongs to the fastest hunter in the neighborhood.

The Hunters of the Air

Mississippi Kite: Catching the Wind

At first glance, a Mississippi kite (Ictinia mississippiensis) looks like it should behave like any other hawk.

It drifts overhead with long, pointed wings, barely moving as it rides the summer air. Then it suddenly changes direction, banking sharply, twisting through the sky, and accelerating after something too small for most people to see.

The first time you notice it, the behavior feels strange.

What is that hawk chasing? Is it chasing dragonflies?

The bird banks again, then again, each turn seeming impossibly precise. Whatever it is pursuing appears far too small to interest a raptor. Yet the longer you watch, the clearer the answer becomes.

While many hawks spend their time searching the ground for prey, Mississippi kites have turned the air itself into a hunting ground. Dragonflies, cicadas, beetles, and other flying insects become meals captured directly on the wing. What appears to be effortless wandering is often an active hunt unfolding overhead (Parker, 2020).

That hunting style explains why they seem so different from other raptors.

The red-shouldered hawk watches a particular place. The red-tailed hawk surveys an entire landscape. The Cooper’s hawk chases prey through trees and backyards. The Mississippi kite is hunting somewhere entirely different.

Its long wings and graceful flight allow it to maneuver with remarkable precision, changing direction quickly as insects dart, climb, and shift with the wind (Parker, 2020).

The same warm air currents that help other raptors gain altitude also gather flying insects into concentrated pockets, creating opportunities for a predator adapted to exploit them (Parker, 2020).

The result is a bird that often feels more like a swallow than a hawk.

An osprey may be hunting fish below. A red-tailed hawk may be watching a field nearby. A Cooper’s hawk may be moving along a forest edge. Above them all, a Mississippi kite may be feeding on insects carried by the same air currents that support the rest of the ecosystem.

The bird is not ignoring the landscape beneath it.

It has simply found opportunity in a place most predators never think to look.

For the Mississippi kite, the sky is not a pathway.

It is habitat.

The Cleanup Crew

Turkey Vulture: Death Becomes Renewal

A turkey vulture (Cathartes aura) lands on your roof and suddenly everyone becomes concerned.

Some people take it as a bad omen. Others wonder if something nearby has died. Before long, the bird becomes the center of attention despite doing little more than sitting still.

The turkey vulture, meanwhile, is completely unaware of the stories being told about it.

Most of the time, something far less dramatic is happening.

A rooftop provides warmth on a cool morning, a place to dry rain-soaked feathers, or a convenient perch where rising air currents can be reached without much effort. The bird is not predicting death. It is simply taking advantage of the landscape (Kirk & Mossman, 2020).

Yet the association exists for a reason.

Unlike the hawks and eagles we have encountered so far, turkey vultures are searching for something very different. They are not looking for prey. They are looking for what remains after life has already moved on.

A dead fish along the shoreline.

A raccoon hidden in roadside vegetation.

A deer beyond the edge of a forest.

But how do they find it?

Part of the answer can be seen on the bird’s face. If you are fortunate enough to observe a turkey vulture through binoculars or at close range, you may notice something unusual about its nostrils, or nares. Unlike our own noses, the openings pass completely through the beak. In the right light, you can literally see from one side of the nostril to the other (Kirk & Mossman, 2020).

That adaptation supports one of the most powerful senses of smell in the bird world. While many raptors rely primarily on vision, turkey vultures are able to detect the scent of carrion from remarkable distances, allowing them to locate food sources hidden beneath vegetation and, in some cases, even beneath the soil itself (Grigg et al., 2017; Kirk & Mossman, 2020).

Finding carrion, however, is only part of the challenge.

Consuming it presents an entirely different set of problems.

The turkey vulture’s bald head, which many people find unsettling, is actually an important adaptation. Unlike a feathered head that could trap blood, bacteria, and other organic material, the bare skin can be cleaned much more easily after feeding. What gives the bird its ominous appearance also helps protect it from the very things it eats (Roggenbuck et al., 2018).

The same is true inside the bird.

Turkey vultures possess an extraordinarily acidic digestive system capable of destroying many of the bacteria and pathogens that would make other animals sick. Organisms responsible for diseases such as anthrax, botulism, cholera, and salmonella are often neutralized during digestion, allowing the vulture to safely consume material that would be dangerous for most scavengers (DeVault et al., 2016; Kirk & Mossman, 2020).

Even their hygiene is unusual.

Turkey vultures practice a behavior known as urohidrosis, in which they defecate on their own legs. While it may seem unpleasant from a human perspective, the highly acidic waste helps kill bacteria picked up while walking on carcasses and also provides a cooling effect during hot weather (Arad et al., 1989; Kirk & Mossman, 2020).

Taken together, these adaptations solve a difficult ecological problem. Dead animals can become reservoirs for bacteria, disease, and decay. Turkey vultures have evolved to exploit that resource while avoiding many of the risks associated with it.

Black vultures, which are often seen alongside them, approach the problem differently. Their nostrils are narrower and not open from side to side. Rather than relying so heavily on smell, they depend more on vision and often watch the movements of turkey vultures to help locate food (Buckley et al., 2020).

That relationship creates an interesting partnership. Turkey vultures are often the first to detect a carcass hidden beneath vegetation, while black vultures are quick to notice where the turkey vultures are gathering. One species excels at finding the scent. The other excels at finding the finder (Buckley et al., 2020; Kirk & Mossman, 2020.

Together, the two species accomplish something few other animals can.

They return nutrients to the landscape.

What appears to be an ending becomes the beginning of something else. Energy stored within a fish, a raccoon, or a deer does not simply disappear. Vultures help move those nutrients back into the ecosystem where they become available to countless other organisms (DeVault et al., 2016) .

The bird on your roof is not waiting for something bad to happen.

More often than not, it is part of the reason the landscape remains healthy after it does.

Black Vulture: Following the Leader

A single turkey vulture on a rooftop often attracts attention.

Ten vultures attract concern.

Unlike turkey vultures, which are frequently seen soaring alone or in small numbers, black vultures (Coragyps atratus) often seem to arrive as a group, called a committee. One bird becomes five. Five become ten. Before long, an entire rooftop, parking lot, or dead tree appears covered in vultures (Buckley et al., 2020).

The first question is usually the same.

Why are there so many?

Part of the answer lies in how black vultures find food.

While turkey vultures rely heavily on their extraordinary sense of smell, black vultures depend much more on vision and on one another. They watch the landscape, but they also watch other vultures. A turkey vulture dropping toward a hidden carcass can reveal an opportunity that a black vulture might never have discovered on its own (Buckley et al., 2020).

That difference creates an unusual relationship between the two species.

Turkey vultures are often the first to locate carrion concealed beneath vegetation or hidden from view. Black vultures are often the first to notice that the turkey vultures have found something worth investigating (Buckley et al., 2020).

One species excels at finding the scent.

The other excels at finding the finder.

Their social nature extends beyond feeding. Black vultures frequently roost together, travel together, and gather in numbers that can seem surprising to people unfamiliar with them. What appears to be a crowd is often a network of birds sharing information about a landscape filled with unpredictable opportunities (Buckley et al., 2020).

That strategy has served them well.

A dead fish washed onto a shoreline, a raccoon along a roadside, or a deer hidden beyond the edge of a forest represents a resource that appears without warning and disappears quickly. By paying attention to one another, black vultures can exploit those opportunities efficiently.

Like the turkey vulture, the black vulture plays an important role in returning nutrients to the ecosystem.

It simply approaches the problem differently.

Where the turkey vulture trusts its nose, the black vulture trusts its neighbors.

The Night Shift

As daylight fades, a different group of predators takes over.

The thermals weaken. The soaring hawks settle. Shadows lengthen across marshes and forests.

Then the owls emerge.

Eastern Screech-Owl: Master of Camouflage

Many people have an eastern screech-owl (Megascops asio) living in their neighborhood and never realize it.

Not because the owl is rare.

Because it is exceptionally good at remaining unnoticed.

You might spend years walking past the same tree without ever seeing this small bird tucked inside a cavity or pressed against the bark. Then one evening, just after sunset, a soft trill or whinny drifts through the yard and suddenly you realize there has been an owl nearby the entire time (Gehlbach, 2009; Ritchison et al., 2020).

The discovery often raises an interesting question.

If eastern screech-owls feed on many of the same insects, rodents, reptiles, and amphibians as some daytime raptors, why don’t we see them more often? (Gehlbach, 2009; Ritchison et al., 2020)

Part of the answer is timing.

While hawks spend the day watching fields, marshes, forests, and backyards, the eastern screech-owl waits for darkness. As daylight fades and the daytime hunters settle into roosts, the owl begins its own shift (Ritchison et al., 2020).

But timing alone does not explain its success.

The owl’s real advantage is concealment.

Its mottled gray and brown feathers blend remarkably well with tree bark, allowing it to disappear into the landscape even when it is in plain sight. During the day, many spend hours motionless inside tree cavities or against trunks where they become nearly impossible to detect (Gehlbach, 2009; Ritchison et al., 2020).

That camouflage allows the owl to remain close to people while largely escaping notice.

Neighborhoods, wooded lots, parks, forest edges, and suburban backyards can all provide suitable habitat. The insects drawn to porch lights, the rodents moving along fence lines, and the small reptiles hiding among shrubs create hunting opportunities throughout the night (Gehlbach, 2009; Ritchison et al., 2020).

By the time most people realize an eastern screech-owl is nearby, it has often been there all along.

Its success does not come from being the largest predator in the landscape.

It comes from being the one you never knew was watching.

Barn Owl: Sound Becomes Sight

A pale shape crosses a field at dusk.

For a moment it hardly seems real. The bird appears almost white against the fading light, gliding silently above the grass before disappearing into the darkness beyond.

The first question is often simple.

What did I just see?

For centuries, encounters like that have inspired stories of ghosts, spirits, and things that move through the night unseen. The barn owl’s piercing scream has only reinforced that reputation. Unlike the familiar hoots people associate with owls, barn owls produce calls that can sound startlingly human, often described as shrieks, screams, or cries drifting through the darkness. Heard for the first time from a forest edge or old barn, it is easy to understand how the bird became woven into folklore (Marti et al., 2024).

Yet the call serves a practical purpose.

In darkness, sound becomes one of the most effective ways for American barn owls (Tyto alba pratincola) to communicate with mates, defend territories, and maintain contact with one another. What sounds eerie to us is simply part of life for an owl that spends most of its time hunting when the rest of the landscape is asleep (Marti et al., 2024).

The hunt itself is equally remarkable.

Barn owls are among the most specialized rodent hunters in North America. Their heart-shaped facial disks act like satellite dishes, funneling sound toward asymmetrical ears capable of pinpointing prey with astonishing precision. A mouse rustling through grass can reveal its location long before the owl ever sees it (Payne, 1971; Marti et al., 2024).

That adaptation helps explain another common experience.

Step quietly into an old barn, abandoned building, or large outbuilding and you may discover one or more barn owls perched overhead. They often watch intruders with an intense stare, swaying and bobbing from side to side as they study the unfamiliar visitor below (Marti et al., 2024).

At first glance, the behavior appears nervous or even strange.

In reality, the owl is gathering information. The subtle movements help it judge distance, depth, and position before deciding whether to remain still or slip silently into the darkness.

Fields, agricultural landscapes, marsh edges, and open grasslands provide ideal hunting habitat (Marti et al., 2024). Every mouse captured represents energy transferred from one part of the ecosystem to another, helping regulate populations that might otherwise grow unchecked.

The pale bird crossing the field is not a ghost.

It is one of the most effective hunters the night shift has to offer.

For the barn owl, sound does not simply reveal the landscape.

It becomes a way of seeing it.

Barred Owl: The Voice of the Swamp

“Who cooks for you? Who cooks for you-all?”

Once you hear it, you rarely forget it.

The call drifts through wooded neighborhoods, swamp edges, and forested wetlands after sunset, often carrying much farther than people expect. Many coastal residents know the sound long before they ever see the bird responsible for making it (Bierregaard et al., 2025).

The question naturally follows.

Who is calling from the darkness?

More often than not, it is a barred owl.

Unlike the barn owl crossing open fields or the eastern screech-owl disappearing into a backyard tree, barred owls (Strix varia) are closely tied to forests and wetlands. Swamps, creek corridors, bottomland hardwoods, and wooded neighborhoods provide the cover, water, and diversity of prey they need (Bierregaard et al., 2025).

The call itself serves several purposes. Barred owls use it to communicate with mates, establish territories, and maintain contact across dense forests where visibility is limited. What sounds like a conversation to us is often exactly that (Bierregaard et al., 2025).

Those forests and wetlands provide hunting opportunities throughout the year. Frogs call from wetland edges. Crayfish move through shallow water. Rodents travel beneath fallen leaves. Snakes, insects, and small birds all become potential prey. Rather than specializing in a single food source, barred owls have learned to take advantage of whatever the swamp provides (Bierregaard et al., 2025).

The swamp, however, does not make hunting easy.

Prey hides beneath vegetation, beneath water, and beneath layers of leaf litter. Fallen logs, tangled branches, and dense understory create countless places to disappear.

Barred owls overcome many of those challenges through silence.

The leading edges of their feathers are specially adapted to break up airflow, reducing the sound of flight to nearly nothing. A mouse rustling beneath leaves, a frog moving along a wetland edge, or a crayfish crossing shallow water may never hear the owl approaching (Bachmann & Wagner, 2016).

For prey, the danger often arrives without warning.

By the time a barred owl commits to an attack, silence has already done much of the work.

That ability helps explain why barred owls are among the most successful predators in the region.

It also reveals something many people do not realize.

Hunting is not simply a switch that turns on when a young owl leaves the nest.

Juvenile barred owls must learn. They practice. They miss opportunities. They refine the skills needed to locate, pursue, and capture prey in a complex environment. In wildlife rehabilitation settings, young barred owls that fail to develop those hunting skills cannot be successfully returned to the wild (Watson et al., 2023).

Instinct provides the foundation.

Experience builds the hunter.

Perhaps that is why barred owls have become such a familiar voice in the coastal night. Their success comes not from mastering a single prey species or hunting strategy, but from learning to adapt to whatever the swamp provides.

For the barred owl, the swamp is more than habitat.

It is a hunting ground, a classroom, and a home.

Great Horned Owl: Ruler of the Night

The night can be surprisingly noisy.

A barred owl calls from the swamp.

Tree frogs answer from the wetlands.

Crickets fill the spaces in between.

Then, sometimes, the woods erupt with alarm calls.

Crows mob during the day. Smaller birds call from hidden roosts after sunset. Even other predators seem suddenly aware that something has changed.

What happened?

Often, a great horned owl (Bubo virginianus) has arrived.

While many predators spend their lives worrying about what might hunt them, the great horned owl occupies a different position in the food web. Rabbits, squirrels, rodents, reptiles, birds, and even other predators can become prey. Where great horned owls occur, few animals completely ignore them (Artuso et al., 2020).

That includes other owls.

Barred owls, screech-owls, and other nocturnal hunters may alter their behavior when a great horned owl is nearby (Artuso et al., 2020). The question is not simply what the owl is hunting.

The question is whether anything wants to become its next opportunity.

Part of that success comes from versatility. Great horned owls hunt forests, wetlands, agricultural fields, suburban neighborhoods, and coastal habitats with equal confidence. Rather than specializing in a single prey species, they take advantage of whatever opportunities the landscape provides (Artuso et al., 2020).

Yet versatility alone does not explain why other animals react when one arrives.

Power does.

A great horned owl’s grip rivals that of a bald eagle. The force generated by its talons can exceed 270 newtons, allowing it to seize and control prey with remarkable efficiency (Ward et al., 2002). Those feet are capable of exerting tremendous force once they close around a target (Ward et al., 2002; Lingham-Soliar, 2014).

Combined with a wingspan approaching five feet, the result is a predator that commands attention even before it leaves the ground (Artuso et al., 2020).

Yet perhaps the most remarkable thing about a great horned owl is how quietly all of that power moves through the landscape.

Like other owls, the leading edges of their feathers break up airflow, reducing the sound of flight to nearly nothing. A bird carrying a wingspan wider than many people are tall can pass overhead with little more than a faint rush of air (Bachmann & Wagner, 2016).

Sometimes not even that.

The first indication that a great horned owl is nearby is often the reaction of everything else around it.

That silence becomes even more effective when paired with another adaptation.

Many people believe owls can rotate their heads completely around.

They cannot.

A great horned owl can rotate its head roughly 270 degrees, allowing it to scan much of the landscape without moving its body (Ward et al., 2002). Unlike our eyes, an owl’s eyes are largely fixed within the skull. To change its view, it must move its head (Ward et al., 2002; Lingham-Soliar, 2014).

For an ambush predator, that matters.

Every movement risks revealing its position. The ability to gather information while remaining nearly motionless allows the owl to watch far more than most animals realize.

And that may be the real reason so many creatures react when one arrives.

The great horned owl combines strength, silence, patience, and awareness in a way few predators can. By the time a rabbit, squirrel, snake, or even another owl realizes it is being watched, the great horned owl has often been watching for quite some time.

Perhaps that is why other animals seem to know when one is nearby.

The great horned owl is not simply another hunter in the night.

It is often the hunter watching the hunters.

Reading the Sky

At first glance, they all appear similar.

Large birds.

Broad wings.

Silhouettes against the sky.

Yet an osprey hovering above the water, a red-shouldered hawk watching from a fence post, a Mississippi kite chasing dragonflies, a vulture riding a thermal, and a barred owl moving through the darkness are not performing the same job.

They are reading the landscape in different ways.

The osprey watches the water.

The red-tailed hawk watches entire fields.

The Cooper’s hawk watches movement between trees.

The Mississippi kite watches the air itself.

Even the vultures, often dismissed as scavengers, are searching for clues that most of us never notice.

The next time a large bird catches your attention, resist the urge to identify it immediately.

Instead, watch what it does.

Does it hover?

Circle?

Perch?

Glide?

Disappear into the trees?

The answer often tells you as much as the feathers.

Because the sky is not filled with birds doing the same thing.

It is filled with specialists solving different problems.

And once you begin to notice those differences, the sky becomes a little easier to read.
