Chirping sounds led Miami airport officials to a bag full of smuggled Amazon parrot eggs. Here's how most of the chicks survived.

The 24 bright green baby parrots began chirping and bobbing their heads the second anyone neared the large cages that have been their homes since hatching in March. 

The Central American natives, seized from a smuggler at Miami International Airport, are being raised by the Rare Species Conservatory Foundation - a round-the-clock effort that includes five hand feedings a day in a room filled with large cages.

At just 9 weeks old, these parrots have already survived a harrowing journey after being snatched from their nests in a forest. They are almost fully feathered now and the staff has started transitioning them from a special formula to a diet of food pellets and fruit.
