Parents, Francisco and Maria Clara - both Lear's Macaws - had laid some eggs in the past but they were not successfully incubated and were just broken. The next time the couple laid an egg, zoo keepers made sure that it would hatch. They placed the egg on an incubator where temperature and humidity can be controlled.
With that, the first Lear's Macaw was hatched in Latin America at Brazil's São Paulo Zoo. The chick was only 22 grams when it hatched. He was fed by zoo keepers every two hours around the clock.
The chick grew rapidly. Photos of the chick's growth were documented from its hatching until he was three-months-old. Keepers named the chick Teobaldo, or Téo for short, after a popular character in Brazilian folk literature, according to ZooBorns.
At three-months-old, Téo weighs 750 grams and still receives liquid food twice a day. Aside from that, he also nibbles on seeds and fruit while learning to fly short distances.
For over 150 years, the birds were only known as pets until a wild population was discovered in eastern Brazil in 1978. About 1,200 Lear's Macaw now live in two wild locations and their numbers are increasing. These parrots are listed as Endangered by the International Union for Conservation of Nature.
