The diet and breeding biology of the Wedge-tailed Eagle
Aquila audax were studied by observation and
collection of prey remains and pellets at three active nests in the Richmond Valley in north-eastern New South
Wales, during July to November 1997. The nests successfully fledged one young each after estimated incubation
ar.d nestling periods of 40-47 days and 75-85 days respectively. The diet consisted of 29 species of vertebrates:
27 per cent birds, 50 per cent mammals and 23 per cent reptiles by number, including a variety of native mammals
but few rabbits in this region of high biodiversity and generally low rabbit numbers. Hunting behaviour, parental
roles and nestling growth are described.
