Grey-faced buzzards can live" by Toyota City of Aichi Pref. is remarkable. In the Toyota natural
Observation Woods, which contain a Satoyama Landscape with Yatsuda, Toyota City has taken the initiative in creating the habitat of frogs grey-faced buzzards prey on and maintaining their foraging grounds by weeding and water management of private fallow rice fields. The conservation of birds of prey with large home range, such as grey-faced buzzards would be promoted by the active involvement of local and regional governments in maintaining an entire local ecosystem including private land in various regions of Japan.

Wings are pointed and narrow; feathers are thin and look transparent when in flight. the tail is ashy brown with horizontal bars on the tail, the iris is bright yellow. Juveniles are often less reddish, with dark brown bars on the abdomen. Also, the face and eye color is brown with a buff color.

Grey-faced buzzards utilize the world's only oceanic flyway for raptor migration. Wind support and geographic features (i.e. islands) enable the birds to migrate in an oceanic flyway. Grey-faced buzzards arrive in the breeding grounds of Japan from late March to early April. It is assumed that males

During the breeding season the grey faced buzzard builds a small stick nest placed in a tree. The tree most of the time being a

Grey-faced buzzards were designated as a "Vulnerable" species in
December 2006 in Japan. Few concrete protective measures have been taken, however, partly because about 90% of the breeding grounds are privately owned and 75% are not legally protected for wildlife. A basic plan for "Creating a wood

The same nest is sometimes used every year until the need of reconstruction arises. Females mostly incubate eggs and nestlings. Males relieve females briefly a few times a day. Eggs hatch from late May to early June about a month after they were laid. Nestlings fledge from late June to early July

Historically, the greatest threat to the grey-faced buzzard in Taiwan has been the uncontrolled hunting of the species in the
Baguashan and Hengchun Peninsula areas. Hunting and trapping of grey-faced buzzard in the Baguashan and Hengchun Peninsula areas has gone on for Generations.

As with most buzzards, these birds utilize rising air currents to gain altitude and cover great distances by soaring during migration. Taiwan lies on a major migration route for the grey faced buzzard, and large numbers may be seen moving southward in
