The macaw is one of the world's animals that is known to have the same breeding partner for their whole lives. Macaw couples do not only breed together but they also share their food and help to groom one another. When the female macaw has laid her eggs (typically 2 but more are common), the female macaw sits on her eggs to incubate them while the male macaw hunts and collects food for them both. The macaw chicks hatch after about a month.
