Hi! I'm Charlie, a Yellow-Collared macaw. Since arriving at the shelter, I've been lucky enough to have been fostered already. See what my foster mom wrote about me below. Update from Charlie's foster mom - January, 2010: Description: Charlie is a yellow-collared macaw, a type of mini-macaw. He is at least 16 years old. Personality: Charlie is a perpetual motion machine. He loves company. He is good company for riding around on a shoulder. He is very vocal.
