These owls are specialized predators, preying mainly on rodents like voles, rats, and mice, playing a crucial role in maintaining natural pest control within their ecosystems. Their distinctive hoarse cat-like call is a key feature used for identification and communication among individuals.
The grasslands and open fields where Short-Eared Owls hunt provide them with the ideal habitat to locate their prey. Their hunting strategy involves flying low over these areas, using their keen senses to detect movements of small mammals hidden in the grass. Once a target is spotted, they swoop down swiftly and silently to catch their prey with precision.

However, these majestic owls face a significant threat in Maryland due to habitat loss. The ongoing destruction of forests and woodlands poses a serious risk to the Long-Eared Owl population in the region.
