Carakiller

The carakiller is a giant flightless bird of prey created for the book and film The Future is Wild. The carakiller inhabits the dry Amazonian grasslands 5 million years from now. The ancestor of the carakiller was the caracara, a terrestrial grassland falcon native to Central America and South America today. The carakiller is much different. The caracara could still fly, but the carakiller became flightless. After becoming flightless, the carakiller specializes in speed. Packs of carakillers scour the grasslands, flushing out babookaris in their wake. The wings of the carakiller became useful in another way - they became arms. The wing is tipped with a sharp claw, used for tearing up its prey. The carakiller stands AbOUT 7 feet tall, sporting a bald head and neck. The only plumage on its head is a fan of display plumage, like those in the tail of a peacock. Carakillers commonly hunt along the edges of brushfires, [...] animals struggling to escape from the flames.

The carakiller resembles the extinct predatory South American bird Phorusrhacos
