Owls, mysterious and wise, are a favorite bird for many. The fact that most of us never see them due to their camouflage and nocturnal habits makes them all the more mysterious. It can also lead you to wonder how many owls live in your own state. In this article we will look at owls in New Jersey. Such as what owls species live in the great state of New Jersey, a bit about their size and appearance, as well as what part of the state they can be found in.

It is currently thought that there are about 19-20 species of owls found in North America. The state of New Jersey is home to at least 8 of these owl species!

Let’s take a look at those species and learn a bit about them, shall we?

8 Owls in New Jersey

While you can always get sightings of uncommon owls passing through or spending time over the border from a neighboring state, our research from allaboutbirds.org and Audubon shows the following 8 owl species are currently considered to be found in New Jersey either year round or seasonally on a consistent basis.

The 8 species of Owls found in New Jersey are Northern Saw-whet Owl, Barn Owl, Great Horned Owl, Long-eared Owl, Short-eared Owl, Eastern Screech Owl, Snowy Owl, and the Barred Owl.

1. Northern Saw-whet Owl

Length: 7.1-8.3 inches
Weight: 2.3-5.3 oz
Wingspan: 16.5-18.9 inches

The best bet for catching a glimpse of a Northern Saw-whet Owl is to learn it’s call and listen for it at night. Luckily, they have a distinct call that sounds like a blade being sharpened with a whetstone, earning the name “saw-whet” owl. During late winter through early summer they tend to call more frequently, so be sure to listen to a high-pitched, “too-too-too” call around then.

They’re small, robin-sized birds with large, round heads and big eyes. In addition to their tiny size, there are a few other reasons why these owls are notoriously difficult to locate. However they do live throughout New Jersey year-round.

Their mottled brown plumage blends in easily to the trees around them, especially when they’re perched motionlessly on a branch. These owls are also naturally secretive, preferring to lay low and avoid being noticed. Like most other owls, they’re also only active at night.


2. Barn Owl

Scientific name: Strix alba
Length: 12.6-15.8 inches
Weight: 14.1-24.7 Oz
Wingspan: 39.4-49.2 inches

The Barn Owl, with its distinctive screech, is a permanent resident of New Jersey and found throughout the entire state. This owl lives up to its name and can often be found occupying barns, and other abandoned structures. They also roost in hollow tree trunks and thick clumps of trees.

These nocturnal predators hunt open fields at night, looking for rodents, which they will swallow whole. This habit of swallowing prey in one gulp means that rather than passing from one end to the other, the owl forms “pellets” which it coughs up. These pellets give an excellent peek into the owl’s diet and are used by researchers to learn more about the owls and their feeding habits, as well as by students.

There are at least 46 varieties of Barn Owl worldwide. The North American version is the largest, while the smallest comes from the Galapagos Islands. The North American Barn Owl is twice the size of its diminutive island cousin. Despite their global presence, habitat loss is beginning to affect their populations in some areas.


3. Great Horned Owl

Scientific name: Bubo virginianus
Length: 18.1-24.8 in
Weight: 32.1-88.2 oz
Wingspan: 39.8-57.1 in

An image of the Great Horned Owl probably comes to mind when you think of owls, with its large booming hoot and long, horn-like tufts where it gets its name from. It’s one of the most common owls in North America and can be found in nearly any semi-open areas between the Arctic and the tropics.

This owl is a very adept predator that can take down birds and mammals much larger than itself, even including other raptors like ospreys. When larger prey isn’t available, it will also consume tiny scorpions, mice, and frogs.

The Great Horned Owl is well adapted to all weather, as it has extremely soft feathers that insulate against the cold and also serve to muffle the sounds of their flight when in pursuit. This amazing bird has a grip strength that can easily sever the spine of large prey, and requires a force of 28 pounds to open back up. The owl uses this vice-like grip to sever the spines of it’s larger prey.

This large owl is a permanent resident of New Jersey and the majority of the United States.


4. Long-eared Owl

Scientific name: Asio otus
Length: 13.8-15.8 inches
Weight: 7.8-15.3 oz
Wingspan: 35.4-39.4 inches

These owls are most comfortable roosting in dense foliage. Though they enjoy the woods for roosting, they need wide-open areas for hunting. The Long-eared Owl can be found in all of New Jersey, but only in the non-breeding season.

The ear tufts on its head that give the Long-Eared owl its name are not its only distinguishing feature. The male owl has a call that can be heard 1 kilometer (just over half a mile) away. The Long-Eared Owl has a variety of calls, it has a typical “hoot” and also makes a barking sound.

The Long-Eared Owl is an efficient hunter, with hearing so precise it can snatch insects in pitch darkness. They are extremely elusive animals but can be spotted by looking for their pellets on the ground. All owls have distinctly shaped pellets. In the winter, when they roost in groups, they may also be easier to spot.


5. Short-eared Owl

Scientific name: Asio flammeus
Length: 13.4-16.9 in
Weight: 7.3-16.8 oz
Wingspan: 33.5-40.5 in

Short-eared Owls prefer open fields and grasslands, and have adapted well to humans by moving into airports as well, as the planes coming in for a landing displace insects for the owl to swoop up and catch. They get their name from their ear tufts, similar to the Great Horned Owl, though they are so short on this species that they’re often invisible.

Short-eared Owls soar silently over grasslands on broad, rounded wings and are most active around dawn and dusk. They use their incredibly acute hearing to track and hunt small mammals and other birds. It’s also one of the few species that has appeared to benefit from strip-mining, as it’s been found often nesting on reclaimed and replanted mines.

This open-country hunter is one of the world’s most widely distributed owls, and among the most frequently seen during the daytime.  Short-eared Owls are capable of traveling long distances, as shown by their distribution, and there have even been reports of these owls descending on ships hundreds of miles from land.

Short-eared Owls are found throughout the entire state of New Jersey in the non-breeding season only.

6. Eastern Screech-owl

Scientific name: Megascops asio
Length: 6.3-9.8 inches
Weight: 4.3-8.6 oz
Wingspan: 18.9-24.0 inches

The Eastern Screech Owl is a common owl found in most wooded areas within its range. It is a year-round resident of New Jersey and is common in any area that has a large concentration of trees. The Eastern Screech Owl’s mottled brown and grey feathers, allow it to blend very well into the trees, making it a master of disguise.

The Eastern Screech Owl is one of the smallest owls in New Jersey and an expert at hiding, but it produces pellets which it expels at the base of the tree where it lives. Not only does this provide a good opportunity to investigate the owl’s diet, but it also gives clues as to where you can find an Eastern Screech Owl.

Although Eastern Screech Owl typically mates for life, occasionally the male will mate with two females. When this happens the second female will kick the first one out of her nest. She will then lay her own eggs, and incubate both sets of eggs.


7. Snowy Owl

Scientific name: Bubo scandiacus
Length: 20.5-27.9 inches
Weight: 56.4-104.1 oz
Wingspan: 49.6-57.1 inches

Snowy Owls are becoming more of a common sight in the United States as their range expands south. Though Snowy Owls will occasionally appear and stay for the Winter in some U.S. states, their habitat is generally much further north.

New Jersey is within the Snowy Owls irruptive range and is one state where Snowy Owls make an appearance some winters. Snowy Owls that have established a site they winter at, may continue to use that same site.

If there are Snowy Owls near you, they are not as difficult to spot as other owls. They roost in obvious places, and unlike most other owls, they are diurnal and thus active during the day. Snowy Owls prefer wide-open spaces for hunting, but they will perch on a high point.


8. Barred Owl

Scientific name: Strix varia
Length: 16.9-19.7 in
Weight: 16.6-37.0 oz
Wingspan: 39.0-43.3 in

The Barred Owl is a common sound to hear in old forests and treed swamps, and their hooting call that sounds like “Who cooks for you? Who cooks for you-all?”. It originated as a bird of the east, but has slowly been spreading through the Pacific Northwest and then southward into California.

Barred Owls are large raptors with stocky bodies and smooth, round heads. Their eyes are wide and so deeply brown that they appear completely black. They have white and brown mottling all over their plumage, with vertical brown barring on their undersides and vertical barring on their upper parts.

Barred Owls can be very territorial, so many bird watchers use this to their advantage. If you find yourself in the woods at night and hear their call, you can try imitating the call with your own voice. If you’re lucky, one of these owls may fly in to investigate you and determine if you’re another owl encroaching on their territory.

Barred Owls are common in New Jersey and found year-round throughout the state.
