What makes a cassowary an endangered species?

Answer 1

Because their population is low and they can become at risk of extinction.

Further information:

There are several factors resulting in the Southern Cassowary being classified as endangered.

Habitat loss is a major factor. As the cassowaries leave their territory in search of food (due to habitat loss) they are more prone to being hit by cars.

Expanding urban development has meant the introduction of dogs and cats which are a major threat to young cassowaries. The introduction of feral pugs has also meant greater competition for food, as well as the fact that the pigs trample the birds' nests, crushing eggs and young birds.

Northern cassowaries are not endangered, but they are listed as 'vulnerable'. The main threats to Northern cassowaries are heavily hunted by the native people on the island of New Guinea, where they are found. The feathers and bones are highly valued for decoration and as gifts in pay-back ceremonies, while the bones are also used as tools. The chicks are also often captured and reared in the villages for food.
