Golden-Shouldered Parrot, Psephotus chrysopterygius
(Illustration: Peter Slater)
Problem:
Golden-shouldered Parrots
are now found on only a few cattle stations in central Cape York Peninsula. The
processes that almost wiped them out operated largely unnoticed until recently.
Slow ‘cool' fires have allowed Broad-leaved Ti-trees to move in and shade out
grassland areas. This leads to the collapse of termite nesting mounds and
provides cover for Pied Butcherbirds that prey on nestling parrots.
Background Information:
The parrot once lived
throughout central and southern Cape York Peninsula. Its range has now been
reduced to a strip 120km wide by 225km long around Musgrave and Koolburra
Stations. Golden-shouldered Parrots live in dry, open eucalypt woodlands and
grasslands. They nest in termite mounds on the ground.
Research:
Drs Stephen Garnett and
Gabriel Crowley, working with the Department of Environment and Heritage, have
identified the following major threats to Golden-shouldered parrots: grazing of
cattle, and too infrequent firing (‘cool fires') which has seen grasslands
replaced by Broad-leaved Ti-tree.
Solution:
Local land-owners have
begun to manage fire so that ‘hot' fires occur every few years late in the dry
season or early in the wet. This way, with limited grazing, the flats stay
grassy, Ti-tree is excluded, the termites have abundant food and the parrots can
feed where they have an open view of predators.
