Officials say two endangered Puerto Rican parrots were born in the wild in a natural nest found outside a national forest in the U.S. territory for the first time in 144 years.

Natural Resources Secretary Carmen Guerrero says scientists discovered the nest in May near the Rio Abajo Nature Preserve and monitored it until they saw the parrots take flight in late July.

She said Tuesday that the two parrots were born to birds that had been reintroduced into the wild by scientists in the Rio Abajo Nature Preserve, one of two breeding centers in the island.

Parrots had previously been born in natural nests in 1973 and 1993 in El Yunque, the only tropical rain forest in the U.S. National Forest system that also serves as a breeding center.
