Profanornis

Profanornis
This flightless bird has a pink, naked head and neck and filthy black feathers. It walks on its long legs, and its head is decorated with wattles and crests.
The profanornis is a large scavenging bird related to storks. They have lost their ability to fly, instead striding on long legs and relying on their size and foul tasting secretions to ward off predators. Although much of their diet comes from carrion, they are not averse to hunting, feeding on frogs, lizards, large insects and anything else they can pick off with their massive beaks. They do not hunt human-sized creatures for food, but may come into conflict with them by trying to drive them off of a kill or when protecting their nests.
Profanornises come in a few closely related species, differing primarily in size and their ornamentation. The smallest are four feet high and the largest six feet high, and some have bony casques on their heads whereas others only have fleshy wattles. These casques, wattles and other structures are used in mating displays. Flocks are typically segregated by sex, and a dominant male may be accompanied by several smaller males who assist his displays and learn from watching him.
