Apo Sunbird (Aethopyga boltoni)

The Apo Sunbird bird, also known as the Philippine Sunbird, is a brightly colored bird that is native to the Philippines. The scientific name of this bird is Aethopyga boltoni. The Apo Sunbird inhabits the highlands of the island of Mindanao, particularly in the province of Cotabato and the mountain range of Mt. Apo.

This bird measures about 10 to 12 cm in length and weighs around 5 to 7 grams. It has a relatively broad and short bill that is slightly curved downwards, which helps it to feed on nectar from various flowers. The male Apo Sunbird has a bright green head and back, iridescent purple wings, and a bright red throat and chest that extends down to its belly. Its tail feathers are also a combination of green and purple. The female, on the other hand, has a duller green color and lacks the bright red or purple colors of the male.

Apo Sunbirds are known to be highly territorial and aggressive, especially in the presence of other birds or when defending their nectar sources. They are active during the day, seeking out flowers to feed on. Their primary diet consists of nectar, insects, spiders, and small fruits.

The breeding season for Apo Sunbirds occurs from January to May, during which the male attracts a mate by performing elaborate courtship rituals, such as flitting its tail, wing displays, and singing. The female lays two eggs in a cup-shaped nest made from moss, lichens, and other materials, which it builds in the branches of trees or shrubs.

The Apo Sunbird is considered vulnerable due to habitat loss caused by deforestation, particularly in the areas around Mt. Apo. However, conservation efforts by the local government and organizations are being undertaken to protect the remaining population of these birds.

In conclusion, the Apo Sunbird bird is a beautiful and unique species that is found exclusively in the highlands of Mindanao in the Philippines. With its brightly colored plumage and territorial behavior, it is both a delight to observe and an important indicator of the ecological health of the region.
