A female mainland Masked Owl Tyto novaehollandiae novaehollandiae
nested in a dead tree which was
standing in pasture and was supporting two recently fledged young when radio-tagged on 17 December 1999.
She was tracked until the tag became detached four weeks later. Her home range was estimated to be 1 125-
1 310 hectares. Foraging activity was focused in dense/medium tree cover with a high proportion of fixes within
100 m of the foresVpasture edge. The European Rabbit comprised 89 per cent of the prey biomass from 277
individual prey items. The owl displayed an apparent aversion to light by remaining inside her roost hollow until
well after sunset on moonlit nights as well as flying away when spotlit.
