The strong decline of the Spotted Quail-thrush is one of a number of
species that was picked up early in the Atlas. In all states (NSW, Vic,
Qld, Tas and SA) it is showing a strong decline of >50% since the First
Atlas. The NSW Bird Atlas is showing a simlilar decline over the last 15
Most other dryland ground dwelling species as a group are showing moderate
to strong declines.
Overall the Atlases and the NSW Bird Atlas is still showing more than twice
as many species decreasing as increasing in all states.
