Oriental Honey Buzzard, 7/5/2012

In Taiwan, Oriental Honey Buzzards are mostly passage migrants in Autumn and Spring. Some are migratory birds in Winter. Yet some have become local birds which can be seen occasionally all year around and breed in March and April.

They live on drone pupas, baby bees or adult bees. Taiwan Forestry Bureau has videotaped a group of Oriental Honey Buzzards working cooperatively to attack a nest of the Vespa basalis and succeeded. In the video, one or two Oriental Honey Buzzards led the attack, spent two to three days in crashing the nest again and again using their bills and paws, and successfully drove the adult bees away from their nest to eat their drone pupas and baby bees.

According to information on the internet, the plumage of Oriental Honey Buzzards is very much diversified and can be roughly divided into three types. The first type is mainly dark-brown for the whole body. The second type is mainly light-brown for the whole body, and the third type is mainly dark-brown on upper body and white from throat down mixed with dark-brown spots.
