how big a macaw can get
Macaws are the largest family of parrots, and some can grow as tall as three feet and weigh up to 4 pounds. Since they are the largest parrots, macaws also have the longest life expectancies. If a young macaw joins your family, it probably will outlive you, as healthy macaws can survive 60 to 80 years. Even the smaller macaws, like the Hahns macaw, can live up 60 years.
