It is amazing how little we know about supposedly common animals, ones that are easily seen and in contact with us. Rabbits were thought to be the main diet for the wedge-tailed eagle. However, the bird consumes other things as well. It should be noted that rabbits were introduced and the eagle must have have relied on other prey before the nuisance animal arrived.
When viral haemorrhagic disease (VHD) wiped out the rabbit population the wedge-tailed eagle actually fared better. Castings, the vomit of eagles, showed that their diet consisted of 20 bird species, seven reptiles, 19 mammals and a crustacean.
Some mammals they ate were large such as the eastern grey kangaroo. The common Galah was a native bird high on the diet. Rabbits are easy to catch when they are plentiful. A fall in rabbit numbers pushed them back to their traditional food sources. Despite the move, native animals have survived. Nature seems to be in balance.
