Melded to the grass as he was, in monochromatic winter pasture shades of taupe, buff, and gray, it was nearly impossible to spot the impostor posing in the dry stalks and twigs. But there he was, a small mound resting along the thicket edge. You can just barely see him in the photo below.
I’ve read the Short-eared Owl flight described as erratic, but I would call it anything but that. They swoop gracefully over fields in multi-directions, with great intention, listening for the sound of voles, moles, mice and other small mammals scurrying through the tall winter grass and phragmites. Flying low while hunting, their wingbeats are smooth and steady.
The Short-eared Owl (Asio flammeus) is called as such because of the little tufts of display feathers atop its head, which aren’t really ears at all. The Long-eared Owl (Asio otus) is a cousin of the Short-eared and it has longer feather tufts. Owls have a highly developed hearing system and their ears are actually located at the sides of their heads, behind the eyes, and are covered by the feathers of the facial disc.
Unlike many species of owls, which prefer forest and woodland, the Short-eared Owls is a bird of open country. They require fields, grasslands, marshes, bogs, heaths, and dunes. Shorties are crepuscular, which means they mostly feed at dawn and dusk.
Short-eared Owls are found the world over on every continent except Australia and Antarctica. Sadly, in Massachusetts, breeding pairs have been driven to the brink of extirpation. There may still be one or two pairs that breed at Nantucket’s Tuckernuck Island but, because of loss of habitat, the Short-eared Owl was listed as endangered in Massachusetts in 1985.
Listen for the Short-eared Owls wing “clapping” in the video below, and some adorable chicks, too 🙂
From Cornell: “Hawaii’s only native owl, the Pueo (Asio flammeus sandwichensis), is a Short-eared Owl subspecies found on all the chain’s major islands. Pueos may have descended from Alaska forebears, taking hold in the islands after the first arriving Polynesians brought owl food in the form of the Pacific rat.”
