Pag-asa was bred by a team of the Philippine Eagle Conservation Program Foundation (PECPF; now Philippine Eagle Foundation), led by executive director Dennis Salvador and camp manager Domingo Tadena. This was a result of 14 years of research.
Pag-asa was bred through artificial insemination 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.
Pag-asa hatched at 10:40 pm PST on January 15, 1992, at the Philippine Eagle Center in Barangay Malagos at the Calinan district in Davao City. Hatched four days earlier than expected, he weighed 134.6 grams (4.75 oz). He had a hard time getting out of his egg, so a PECPF staff member cracked it.
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.
