This bird has something that most birds lack, and lacks something that most birds have.
Answer:
This is a Turkey Vulture. It has an excellent sense of smell, which most birds do not. Its sense of smell helps it find its food, dead animals.
It is called a Turkey Vulture because of its red, featherless head. Besides the lack of feathers on its head, the Turkey Vulture also lacks a syrinx, the bird equivalent of vocal cords. The only sounds they can make are hisses and low grunts.
