Australia and the Grass Owl seem to be made for each other. The country has
huge areas of grassland and, above all others, it is the Grass Owl that is
adapted to live there. While other owls need hollow trees for roosting and
nesting, and often use perches to hunt from, the Grass Owl requires none of
these. It hunts exclusively on the wing, and roosts and nests in the grass,
shaping chambers, tunnels and escape routes, all invisible from above.
So much of Australia appears to be Grass Owl country, and yet it is one of
our rarest owls. Ground-nesting may be the problem, making it vulnerable
to snakes, goannas, monitors and even the very rats on which the owls prey.
Eggs or young are plundered rendering a high failure rate among the species.
