and hatched through a combined artificial and natural incubation technique taught by the World Center For Birds of Prey. He was the first offspring of Philippine eagles Diola and Junior. Then 29-year-old Diola laid the egg, and Junior, found in Agusan, donated sperm. She sat the egg for twelve days before it was transferred to an incubator. According to the PECPF, the breeding technique improved the hatchability of the egg by as much as 30 percent.

declared Pag-asa's hatch day as Philippine Eagle Day, or Pag-asa Day. Since then, the Philippine Eagle Center has established breeding and rearing protocols.


Adult life

Pag-asa was unsuitable for release and remained in captivity, due to dependence on humans, particularly his keeper, Eddie Juntilla, on whom he had imprinted. Pag-asa sired his first chick on February 9, 2013, through artificial insemination. It hatched at 1:55 am PST from an egg laid by 29-year-old Kalinawan. It weighed 158 grams at its hatching, and was the first offspring of an eagle bred in captivity. The chick was named Mabuhay and determined to be female. Pag-asa died on January 6, 2021, aged 28. He had infections associated with
