The cassowary is a large, flightless bird native to the tropical forests of New Guinea, nearby islands, and northern Australia. It is known for its striking appearance, featuring a tall, helmet-like casque on its head and vibrant blue and black plumage. Cassowaries can grow up to 6 feet tall and weigh between 100 to 150 pounds, making them one of the heaviest bird species. These birds are primarily frugivorous, meaning they mainly eat fruits, but they also consume fungi, seeds, and small animals. Cassowaries play a crucial role in their ecosystem by dispersing seeds through their droppings, which helps maintain the health of their forest habitats.
