Are mound springs important refugia for Eastern Grass Owls Tyto longimembris in south-western Queensland?

This note reports an incidental observation of an Eastern Grass Owl Tyto longimembris which was disturbed from its roosting site in wetland vegetation associated with a natural mound spring in south-western Queensland. There are only two published records of the Grass Owl using this rare habitat type, although there are records from similar habitats associated with artificial bore drains. The potential importance of mound-spring habitats for Grass Owls is explored, and some of the threats facing these sites are described.
