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 small animals and fungi. Cassowaries play a crucial role in their ecosystem by dispersing seeds through their droppings. Despite their size, they are known for their speed and agility, capable of running up to 30 miles per hour.
