Rescued Owl Is Getting 'Cage Rest' The grounded saw-whet owl we wrote about on Friday after it was dropped off at the parks department's headquarters in a shoe box is recovering quietly at a wildlife rehabilitation center on Long Island. The little owl (saw-whets are among the smallest owl species, and this owl weighs three ounces) was first taken to the Wild Bird Fund on the Upper West Side, where rehabilitators recognized signs of head trauma. "He had a bad head bang," said Rita McMahon, the director of the bird fund. His left eye was more closed, and the pupil was dilated. It seemed like there was a bit of swelling. To recover, Ms. McMahon said, the owl needs some time, and a cage big enough to flap around in, so on Saturday the bird was sent to Wildlife in Need of Rescue and Rehabilitation in Massapequa, N.Y. There, Bobby Horvath, who has worked with many injured New York CIty raptors, reported Monday afternoon that the owl was spending a lot of time "just kind of hunkered down," though he added, "It becomes alert when we open the cage to drop food in." One of the owl's wings is a bit droopy, Mr. Horvath said, but X-rays showed no broken bones, so the prognosis for full recovery and release (in Brooklyn, where the owl was found) remains good. "It's just nutrition, cage rest, and we've got him on pain medication and an anti-inflammatory," Mr. Horvath said. For now, you just keep it dark, quiet and as calm as possible.
