Girlie is estimated to be 38 yrs old, with her right eye wounded by a slingshot used
for her capture in Bukidnon. She was the natural pair of Tsai and was the first
Philippine Eagle in captive breeding history to lay a fertile egg, which unfortunately
did not hatch.
The Philippine Eagle (Pithecopaga Jefferyi) is the Philippines national bird.
It is the largest eagle in the world. This magnificent bird proudly stands at
one ( 1 ) meter in height and has a wingspan of about two (2) meters. Its head is
adorned with pointed crown feathers known as “crest” and it has a massive arched beak.
The Philippine Eagle has been given mighty names in the various regions such as
“Haring lbon”, ” Agila”, “Mamboogook”, “Garuda”, “Banog”, “Asinmanonoy”, and “Biok”.
The female Philippine eagle is sexually mature at age five (5), the males at seven (7).
The female lays only one (1) egg every two (2) years. Nests, measuring 1-2 meters wide,
are built on large trees usually found along steep slopes and ravines. Both parents
take turns incubating the egg for about 60 days. At 22 months, the young eagle leaves
its parents’ home and searches for its own territory.
The Philippine eagle is endemic to the Philippines and is known to inhabit the forested
areas of the Sierra Madre and the Cordillera Mountain Ranges of Luzon, Samar, Leyte
This critically endangered bird with a current population estimate of about 500 pairs
throughout the archipelago faces the risk of extinction due primarily to loss of habitat.
If this persists, the young eagle would have no territories of its own to perpetuate
its kind. Hunting of the species has also contributed to their declining population.
The Philippine Eagle was once known as the monkey-eating eagle because of earlier
reports that it preyed solely on monkeys. However, this bird actually sits on top of
the food chain, with other animals such as flying lemurs, squirrels, snakes, monitor
lizards, bats and owls forming part of its diet.
