Collaborative research led by The University of Queensland has found that threatened birds have disappeared from almost 70% of Australia since European colonisation.
A critically endangered bird, known as the Regent Honeyeater, used to flock in the thousands to the north of Brisbane. The bird is now rarely seen in a group of more than a dozen and it is estimated that there are only about 500 of the birds remaining, but Professor James Watson believes that there is a chance the Honeyeater can make a comeback.
