Stuart,
Whilst there are a few migratory owl species, all tytonid owls tend to be
sedentary. The furthest ring recovery of an adult Barn Owl was 500 km away from
its home, the furthest of a young one was 1600 odd km away (Koenig et al. 1999:
Owls. A guide to the owls of the world - 1st edition [I don't have the second
edition here]). Ringing recoveries of (Eastern) Barn Owls involving distances
of 65-840 km have been reported from SE Australia, with vagrants reaching as
far as NZ (del Hoyo et al. 1999 HBW, see also Higgins 1999 HANZAB).
Cheers,
Nikolas

Most owls seem to be sedentary because the live in environments with a wide
range of food. Regarding Barn owls can anyone comment or provide a source
that indicates that Barn Owls move out of a normal home range to benefit
from food gluts.
