The Southern Cassowary (Casuarius casuarius johnsonii) is an endangered flightless bird native to the tropical rainforests of northern Queensland. Standing up to two metres tall, it is striking for its bright blue skin, red wattles, and tall casque. Cassowaries play a vital role as “rainforest gardeners,” dispersing seeds over large areas. Their populations are threatened by habitat loss, vehicle strikes, dog attacks, and limited genetic diversity. While not extinct, some local populations have disappeared, making conservation efforts critical.
