Feeding Habits
Eastern Grass Owl predominantly preys on rodents and occasionally consumes small marsupials, ground birds, reptiles, frogs, and large insects. Eastern Grass Owl hunts with a distinctive low flight, resembling harriers, diving into grass for prey. Feeding activity peaks during twilight and can extend to mid-morning, particularly during prey population surges.
Habitat
Eastern Grass Owl thrives predominantly in expansive grasslands, including tall grass jungles, open grassland areas and paperbark savannas. These regions often encompass marshes, floodplains, and heathlands. The species especially favors undisturbed habitats, although it is known to adapt to human-altered environments like agricultural fields and young pine plantations. Roosting and nesting typically occur within thick grassy cover or swamp vegetation, where eastern Grass Owl form intricate systems of tunnels and use flattened vegetation. In broader geographical terms, eastern Grass Owl inhabits grassy hillsides, mid-mountain grasslands up to 2500 meters, marshy heaths, swampy tussock grasslands, and floodplain regions enriched with sedges, rushes, and lignum. While usually ground-dwelling, some individuals have been spotted perching atop pine trees.
