Predators. Dingoes and Wedge-tailed Eagles prey on Emus. The fathers carry the chicks dung away in their beaks and put it a long way away to divert predators. Emu eggs are eaten by reptiles such as goannas and snakes, other birds such as the Black-breasted Buzzards and mammals such as Dingoes.
Small stones are swallowed to assist in the grinding up and digestion of the plant material. Individual stones may weigh 45 g (1.6 oz) and the birds may have as much as 745 g (1.642 lb) in their gizzards at one time. They also eat charcoal, although the reason for this is unclear. Captive emus have been known to eat shards of glass, marbles, car keys, jewellery, and nuts and bolts.
