Wild Scarlet Macaw populations are declining due to the illegal trade and habitat loss. Although Scarlet Macaws lay 2-4 eggs, macaw parents will only feed the 1st and 2nd chick, while the others starve to death. We will develop techniques to increase survival of these chicks by moving them into new nests with no chicks, or only 1 chick. Our research suggests that the new parents will adopt and care for their new chicks, allowing them to reach maturity and fledge from the nest.
