Glutornis gigas
The glutton is the largest predator of Tularean Antarctica. A descendant of the giant petrels, it is completely flightless and has highly atrophied wings. It is robustly built, with particularly sturdy bones in the neck and legs. Its skull is broad and bears a powerful, segmented beak. As with many procellariiform birds, its tube-shaped nostrils grant it a powerful sense of smell. Gluttons can grow up to 2.5 meters tall and weight around 800 kg.
The glutton is an ambush predator, using its beak and feet to dispatch prey. It has a habit of picking up prey in its jaws and slamming it on the ground or against nearby trees or rocks to kill it. Adaptations that formerly helped the skull withstand diving now help it withstand the stress of this action. It will prey upon any animal it can kill, but prefers those small enough to pick up. Gluttons are solitary, with the exception of parents raising nestbound offspring.
