This allows the owl to fly slowly and quietly, making it an effective hunter. Its wings also have a distinctive shape, with a subtle curvature that enables the owl to make sharp turns and quick changes in direction.
Long Eared Owl Habitat and Distribution
You’ll find Long Eared Owls in woodland edge habitats, where they inhabit the transition zones between forests and open areas.
They’re also known to dwell on the forest floor, where they can be found in dense undergrowth and thick vegetation.
Additionally, they occupy open country territories, including grasslands, heathlands, and agricultural areas.
Woodland Edge Habitats
Woodland edge habitats, where forest and open land converge, provide Long Eared Owls with a unique combination of shelter, food, and breeding opportunities. As you explore these edges, you’ll discover that the Long Eared Owl’s affinity for woodland secrets lies in the intricate balance of light and shade, structure, and food availability.
| Habitat Feature | Edge Exploration | Woodland Secrets |
|---|---|---|
| Tree density | Thinning trees create perches for hunting | Concealed hunting spots |
| Understory vegetation | Dense undergrowth provides shelter | Hidden roosting sites |
| Edge topology | Varied terrain creates ambush points | Stealthy hunting advantages |
| Prey abundance | Edge habitats attract small mammals | Abundant food sources |
| Human disturbance | Limited human activity preserves habitat | Undisturbed breeding grounds |
Forest Floor Dwelling
Several square kilometers of forest floor, where the canopy overhead filters the sunlight, provide Long Eared Owls with a secluded environment that fosters their unique lifestyle.
You’ll find these birds inhabiting areas with dense undergrowth, where the leaf litter is thick and the terrain is varied.
Here, the owls’ ground-dwelling habits come into play, as they navigate through the underbrush with ease, their exceptional hearing and vision guiding them through the dimly lit environment.
As you explore the forest floor, you’ll notice that Long Eared Owls tend to favour areas with scattered tree cover, where the canopy is less dense and the understory is more prominent.
This allows them to fly silently, using the trees as cover, and to perch low to the ground, where they can remain inconspicuous.
Their ability to thrive in these environments is a testament to their adaptability and specialized hunting skills, which enable them to exploit the abundant small mammal populations that inhabit the forest floor.
Open Country Territories
Open grasslands, heathlands, and shrublands provide Long Eared Owls with an alternative habitat that differs significantly from their forest floor dwellings.
You’ll find these owls inhabiting open country territories, characterized by low vegetation and scattered trees. In these areas, you’re likely to spot them perched on fence posts, rocks, or low-lying branches, scanning the ground for small mammals and other prey.
In rural landscapes, Long Eared Owls often occupy abandoned burrows, rock crevices, or hollow trees, using these structures as shelter and nesting sites.
They tend to favor areas with low human disturbance, where they can hunt and breed undisturbed. The open grasslands and heathlands offer an ideal environment for these owls, providing ample space for foraging and flying.
As you explore these territories, pay attention to the owl’s unique adaptations, such as its ear tufts and facial disk, which enable it to thrive in this distinct habitat.
Behavior and Activity Patterns
As dusk approaches, you’ll likely find Long Eared Owls becoming increasingly active, their behavior shifting from sedentary to stealthy hunters.
They’ll venture out of their hiding spots, using their exceptional hearing and exceptional night vision to locate prey under the cover of darkness. Moonlit hunting is a crucial aspect of their behavior, allowing them to capitalize on the nocturnal activities of small mammals, birds, and insects.
During nocturnal roaming, Long Eared Owls will fly silently, using their acute hearing to pinpoint potential prey.
They’ll then swoop down, using their talons to grasp and kill their quarry. This silent, swift hunting style allows them to catch their prey off guard, making them highly effective predators.
As the night wears on, you’ll notice Long Eared Owls returning to their roosting sites, often in small groups.
They’ll spend the remainder of the night perched, resting, and digesting their meals. This nocturnal behavior is crucial to their survival, allowing them to thrive in environments where diurnal predators may dominate.
Identifying Vocalizations
You’ll want to listen for the Long Eared Owl‘s vocalizations, particularly at dusk when it’s most active.
Its calls typically consist of a series of low, whistled notes, often described as a slow, hollow “hoo-h’ooh” or “hoo-hoo-h’ooh”.
Pay attention to the whistled contact notes, which are usually softer and more nasal than its other vocalizations.
Calls at Dusk
Identifying a Long Eared Owl‘s vocalizations is crucial for distinguishing it from other owl species, especially at dusk when its calls are most active.
During this period, you’ll often hear a Dusk Chorus, a series of short, melancholic whistles that are typically repeated at intervals of around 2-5 seconds.
The pitch and tone of these calls are distinctive, often described as mournful or haunting. Pay attention to the frequency and pattern of these calls, as they can vary depending on the individual bird and its level of excitement or alarm.
As the evening wears on, the Dusk Chorus gradually gives way to Evening Silence, a period of relative quiet during which the owl’s vocalizations become less frequent and more subdued.
It’s essential to recognize this transition, as it can be an important indicator of the owl’s presence and activity patterns.
Whistled Contact Notes

Whistled Contact Notes (Identifying Vocalizations)
In addition to the Dusk Chorus, Long Eared Owls use Whistled Contact Notes to communicate with other owls, particularly during courtship, breeding, and nesting periods.
You’ll recognize these notes as a series of short, high-pitched whistles, often described as a descending phrase or a soft, melancholic hoot.
These whistled contact notes serve as a primary means of communication among Long Eared Owls, allowing them to maintain contact and coordinate activities without alerting potential predators.
When you’re in the field, listen for these whistled warnings, which can be a vital cue in detecting the presence of Long Eared Owls.
Interestingly, these owls also engage in silent communications, where they use body language and visual cues to convey information.
By paying attention to both vocalizations and visual behaviors, you’ll increase your chances of identifying Long Eared Owls.
Remember to focus on the distinct characteristics of the Whistled Contact Notes, and you’ll be well on your way to distinguishing these owls from other species.
Distinguishing From Other Owls
While scanning the night sky for a glimpse of the Long Eared Owl, it’s essential to recognize that several other owl species share similar characteristics, making accurate identification a challenge.
You’ll need to be aware of the owl spotting challenges that can lead to misidentification. For instance, the Short Eared Owl, another nocturnal hunter, has similar ear tufts and facial disk patterns.
However, the Short Eared Owl’s ear tufts are shorter, and its facial disk has a more pronounced white border.
Camouflage strategies also come into play, as many owl species have evolved to blend in with their surroundings.
The Long Eared Owl’s mottled brown plumage, for example, helps it merge with tree bark and foliage. To distinguish it from other owls, look for its distinctive black and white facial markings, as well as its long ear tufts, which are usually visible even when the bird is at rest.
Spotting Tips and Techniques
Three key elements to focus on when spotting a Long Eared Owl are its perch, posture, and proximity.
You’ll often find these owls perched on low-hanging branches, fence posts, or even the ground, usually within 10-15 feet of the ground.
Pay attention to their posture, as they tend to sit upright with their ears erect, giving them a distinctive silhouette.
Proximity is also crucial, as Long Eared Owls are more tolerant of human presence than other owl species, allowing you to get relatively close for observation.
When spotting a Long Eared Owl, keep in mind their nocturnal habits.
They’re most active during moonlight hunting hours, and their silent flight makes them difficult to detect.
Listen for their soft, whistled calls, often described as a low-pitched “hoo” or “keeee.”
Be patient and quiet, as sudden movements can scare them off.
With practice and attention to these details, you’ll increase your chances of successfully spotting a Long Eared Owl in its natural habitat.
