Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity.
The Australian golden whistler or golden whistler, is a species of bird found in forest, woodland, mallee, mangrove and scrub in Australia. Most populations are resident, but some in south-eastern Australia migrate north during the winter. Its taxonomy is highly complex and remains a matter of dispute, with some authorities including as many as 59 subspecies of the golden whistler, while others treat several of these as separate species.
