Vultures are large birds that circle over dead bodies in Yara. They never attack you, you can hunt them for meat that trades for Durable Plastic, and circling vultures often lead you to loot.
Wait for a vulture to land rather than wasting ammo on it in flight. On the ground it is an easy shot.
Follow circling vultures. They tend to gather over corpses, and those often have something worth picking up.
Barracuda
Barracuda are fish you catch at fishing spots around Yara's coast, and their meat is useful for trading and cooking. A Barracuda brochure shows you where several of those spots are.
Black Hawk
The black hawk is a bird of prey you can hunt in Yara for its meat. It poses no danger to you, and the meat trades for Durable Plastic, which makes it worth a quick shot when you see one.
Bull Shark
Bull sharks are the dangerous sharks in Yara's waters, and you can also catch them at marked fishing spots. Their meat is good trade stock, but swimming near one is a bad idea.
Cougar
Cougars are big cats that stalk Yara's mountains and attack you on sight. They are worth hunting, because cougar meat trades for Durable Seals and cooks into stealth-boosting Ninja Nachos.
