Abstract:

A study of the movements of two pairs of nesting Long-eared Owls (Asio otus) was conducted during the spring and summer of 1982. Activity patterns, movements, and home-range use of the owls changed during the nesting season. The female incubated and brooded the young, while the male did most of the foraging, particularly when the female was attending eggs or very small nestlings. Mates shared a common core home range immediately around the nest site, but foraged in different areas away from the nest. The home-range areas of adjacent nesting pairs overlapped. Although changes in temperature significantly affected the movements of one of the female owls, wind speed, precipitation, and cloud cover appeared to have little influence on movements of the birds. During their nocturnal period of activity, owls were least active from 20:00-22:00 and 05:00-06:00.
