- Wingspan: 35-39 inches
- Status: Varies; some populations are of conservation concern
Long-eared Owls are forest-dwelling birds found in Louisiana, often in dense coniferous or deciduous woodlands.
They are named for their distinctive long ear tufts, not actual ears but feather extensions. Long-eared Owls are known for their cryptic plumage, providing excellent camouflage among tree branches.
These owls are primarily nocturnal hunters, preying on small mammals like voles and mice. Long-eared Owls are highly secretive and tend to roost in dense vegetation during the day.
Conservation efforts are crucial for protecting their habitats, as these owls are susceptible to disturbances and habitat loss. Maintaining healthy forest ecosystems is vital for the long-term survival of Long-eared Owls in Louisiana.
7. Short-eared Owl
