The Eastern Screech-Owl is a small owl species native to most wooded environments of the eastern half of North America, from the Canadian provinces to Florida and Texas.

Eastern Screech-Owls are relatively small and exhibit a complex pattern of gray or reddish-brown coloration, which provides excellent camouflage against tree bark.

These owls are known for their distinctive call, which is often described as a haunting trill or a whinny-like sound. Despite their name, they do not actually produce a “screech.”

Eastern Screech-Owls feed on a variety of prey, ranging from small mammals and birds to insects and even earthworms. It is primarily nocturnal, hunting at night from a low perch and swooping down onto prey.

Eastern Screech-Owls nest in tree cavities or abandoned woodpecker nests, but they readily adapt to nesting boxes where natural cavities are not available. They typically lay between 2 to 6 eggs, which are incubated primarily by the female.

Barred Owl (Strix varia)

The Barred Owl is a medium-sized owl with a barred pattern on its chest and belly. They have large yellow eyes that allow them to see well in low light conditions. Their ears are not very large which means they do not hear very well but they have excellent hearing abilities which allow them to detect sounds up to 1 mile away. Their feathers are brown and streaked with white, and they have black bars on their chests and wings.

Their habitats include forests, woodlands, orchards, parks, farmland and suburban backyards.

Barred Owls (also known as hoot owl) eat small mammals such as mice, rats and squirrels. They also eat insects such as beetles or grasshoppers. These owls hunt during the day when it is light out so that they can see their prey better than at night when they would be using senses other than sight like sound or smell to find their food source.

Barred owls are monogamous birds which means they mate for life. They build nests in trees or cavities on the ground and lay 2-4 eggs per year. The incubation period for these eggs lasts about 28 days before hatching takes place.

Barn Owls are typically found in open habitats, including farmland, woodland, and marshes. They are named for their habit of nesting in human structures such as barns, church towers, and in the hollows of large trees. These owls are nocturnal, hunting at night and roosting during the day.

The diet of Barn Owls primarily consists of small mammals, particularly rodents such as mice and rats. They are known for their silent flight, which allows them to sneak up on their prey without detection.

Barn Owls have a unique nesting behavior. They do not build nests, but instead, lay their eggs directly on the bare surface of a secluded ledge or cavity. A female typically lays 4-7 eggs, and both parents help incubate the eggs and care for the chicks.

The owls are predominantly brown with buff and white accents throughout their body and wings, and dark patches around their yellow eyes.

Short-eared Owls diet consists largely of small mammals, especially voles. However, they are opportunistic hunters and will also prey on a variety of other animals, including other birds, when available.

Their habitat is characterized by open areas like grasslands, marshes, and tundra. They nest on the ground, which is unusual for owls, and this makes them vulnerable to ground predators. As such, they often live in areas with tall grasses or other ground cover for protection.

Northern Saw-whet Owls have dark brown eyes, white eyebrows, and yellow beak. It has brownish-grey feathers that are spotted with white. The owl’s legs are covered in feathers and appear nearly invisible when the bird is perched on a branch or tree.

In the winter they migrate south to warmer climates. They prefer to live in dense coniferous forest with large trees but will occasionally nest in shrubs or other vegetation that can protect them from predators.

The Northern Saw-whet Owl eats mice and voles (small rodents), small birds, frogs, salamanders, moles and shrews, but unlike most owls they chop their prey up and spread over a few meals. They will also eat insects like beetles and grasshoppers if they are available. It hunts from a perch at night using its excellent hearing to locate prey items within about 30 feet (9 meters) of its nest.

These owls nest in tree cavities usually located close to water sources such as lakes or rivers where they can find their food source (insects). They lay 2-4 eggs at one time which incubate for about 30 days before hatching.

This is an adaptation to life in the Arctic, where there can be 24 hours of daylight in the summer. Their diet mainly consists of small mammals, particularly lemmings, but they are known to eat a variety of animals including birds, fish, and even carrion when necessary.

Snowy Owls nest on the ground, usually on a mound or boulder. Their breeding success is closely tied to the availability of food, and in good years a single pair of owls can raise a large brood of chicks.

Tips on How to Spot Owls in Maine?

  1. Know the Prime Locations: Some of the best places to see owls in Maine include Acadia National Park, Baxter State Park, and the Maine Birding Trail, which features numerous wildlife areas where owls are often sighted. In winter, the snowy fields of Aroostook County can offer sightings of the majestic Snowy Owl.

  2. Be Aware of the Time: Owls are mainly nocturnal, so the best times to spot them are at dawn and dusk. During the mating season, in late winter and early spring, you may hear their calls more frequently as they establish territories and seek mates.

  3. Learn the Calls: Different species of owls have unique calls, and learning these can help you identify them even if you can’t see them. Recordings of owl calls can be found in various bird-watching apps and websites.

  4. Look for Signs: Look for owl pellets at the base of large trees, which can indicate an owl’s roosting spot. Also, in the winter, you can look for their distinctive tracks in the snow.

  5. Move Quietly and Be Patient: Owls are secretive and can be easily spooked. Move slowly and quietly, and be prepared to wait. Sometimes, the owls will come to you!

  6. Equip Yourself Properly: A good pair of binoculars or a spotting scope can be invaluable, as owls can often be quite high in trees or hiding in dense foliage. A flashlight with a red filter can help spot owls at night without disturbing them.

  7. Join Bird Watching Groups: Connecting with local bird watching groups or guided tours can enhance your birding experience. They often know the best spots and times for seeing specific species.
