Characteristics

With a total length of 40-50 cm (16-20 in) and a wing-length of about 35 cm (14 in), it is the largest owl in the Philippines, but among the smallest members of the genus "Bubo".Züchner, T. (1999).

Behavior

Little is known about the behavior of this secretive species, but the powerful feet suggest it feeds on small mammals and birds.

This eagle-owl lays one egg per clutch and has an incubation period of 35 days. [ [http://philippinen.ded.de/cipp/ded/custom/pub/content,lang,2/oid,4599/ticket,g_u_e_s_t/~/Fresh_hope_for_the_Philippine_Eagle_Owl.html#top DED, The DED in the Philippines] ]

Breeding in captivity

In December 2005, Negros Forests and Ecological Foundation (NFEFI) in Bacolod City was the first conservation center in the world to successfully hatch a Philippine Eagle-owl (aptly nicknamed "Bubo") in captivity and it has the only breeding pair of these owls in captivity anywhere in the world.

On November 21 2005, conservationists at the center made world history when it successfully bred in captivity a Philippine Eagle-owl. Notably NFEFI had first secured the first-ever captive breeding loan between DENR-accredited institutions in the Philippines, consisting of three pairs of eagle-owls from the Avilon Montalban Zoological Park in Montalban, Rizal and transported them to Bacolod in December 2002. Two pairs showed attraction, and the couple “"Hinahon"” and “"Suplada",” -- local term for “"calm"” and “"snob"” -- made courtship. It was on November 21 2005, that an owlet was discovered in the nest, about three days old, and named “"Bubo".” As Bubo grew, Suplada taught it how to tear pieces of mouse meat, thus rearing it.

In 2006, Suplada also laid one egg and another owlet was hatched through the aid of the World Owl Trust, Flora and Fauna International-Philippine Biodiversity Conservation program and the Avilon Zoological Park in Montalban Rizal.
