Harbingers are descendants of mutated Turkey Vultures, and are known for foreshadowing death across the wastes. Many consider them to be dangerous vermin while others see them as important allies.
Harbingers are a fairly common bird in the southern United States and can be seen all over the country during the summer. They are around two feet taller than their forerunners, darker coloration, and sharper, and stronger claws; besides that there is little difference. The real difference is their behavior. Harbingers are much smarter than their descendants. They have been known to lead raiders and hunters to weakened quarry, by circling around the target. Some Harbingers are trained with falconry methods; thus forging a relationship out of respect,and trust of their "Partner" to share the spoils of battle with them. Also unlike their ancestors, they will use group hunting tactics such as distraction to separate prey from the group and then brutally attack.

Harbingers also make great hunting allies due to the ability to find weak prey and give hunters early warnings of what is approaching.
