129 species of birds native to New South Wales are formally listed as extinct or threatened with extinction. The recordings you can hear are bird species that sang in central Sydney before Europeans settled and gradually forced them away. Some of these birds can still be heard on the city margins where they find food and shelter in thick native vegetation. Others have retracted still further.

Habitat loss is the over-riding threat to bird survival. These are some of the many birds which may have once lived in Angel Place, before the city replaced their native habitats.
