With a wingspan of up to 2.5 m, the wedge-tailed eagle is the largest bird of prey in Australia. It soars and glides majestically in the air currents for up to 90 minutes at a time, reaching altitudes that can go beyond 2000 m. The wedge-tailed eagle can be found all over Australia, but it is more commonly found in open woodland areas with a good grassy ground cover. Between 80 and 90 per cent of a wedge-tailed eagle's diet is made up of ground-dwelling animals, including both mammals and reptiles. Rabbits, wallabies and small kangaroos form the main part of their diet, although they will also eat snakes, lizards, large birds, possums, foxes and feral cats.
