Cassowaries often eat fruit and seeds that they find along the ground. These birds also eat insects and small mammal carcasses along with fish and certain types of vegetation.
The cassowary is a scavenger, so it largely feeds on whatever it can find. The birds feed alone and have digestive systems that allow them to eat seeds and berries that are poisonous to humans. When chicks hatch, the adult bird leads them to sources of water and to various fruit trees until they are old enough to secure food on their own. Cassowaries are native to rainforests, mainly in New Guinea and northeastern Australia. The birds are nonmigratory and stay in the same area their entire life unless their food sources become depleted. In that case, they will move on but rarely travel far.
