This is a fairly uncommon species that can change form from human to a single animal shape. The clans are grouped into animal types: birds of prey, songbirds, bear, deer, canine, and the big cats. These clans are further separated into families: raptors (hawk, falcon, and eagle), songbirds (which mainly stay together), bear (polar, brown, black, and grizzly), deer (elk, white-tailed, caribou, and mule deer), canines (fox, wolf, coyote and the house-mutt), and big cats (tiger, lion, jaguar, and cheetah). There is also a clan of otter changelings who live out on the open ocean waters. Each Changeling has the ability to sense the animal/human half of another, they cannot sense a bond pair, however.

They can only Change after their 18th birthday (the coming of age). After midnight of their 18th birthday they can change at any time, anywhere, and with practice can learn to include some clothing in their shifts so they aren't totally in the nude. The month before coming of age, their strength and agility grows quickly. The person's personality sometimes reflects what they will become; songbird and deer, for instance, are usually shy and reserved, and often times bears, the most temperamental, are high-strung and easy to anger.
