Many native Australian bird species are declining. Birds of garden, water, scrub and woodland are showing marked falls in their populations says a new report by Birds Australia (BirdLife in Australia). The encouraging news is that the status of some species is improving as a result of conservation action.
This is the sixth 'the state of Australia's birds' report, and presents an up-to-date overview of the health of bird populations in Australia and the main challenges to their sustainability. This 2008 report focuses on trends in bird populations revealed by around 50 long-term monitoring programs that have been running for up to 40 years.
Trends in bird populations are mixed, but more species are in decline than were reported in 2003. Common birds are far less common than they once were, for example populations of the familiar Australian Magpie Gymnorhina tibicen have slumped.
"Many, and perhaps most, of our native birds are in decline for a range of reasons including habitat loss and introduced predators", said Dr Graeme Hamilton - Birds Australia CEO.
