Grey-faced Buzzard often acts alone and only forms groups during migration. During the day, it hovers over the forest, flies at low altitude, or soars in circles. Sometimes it also perches on the tops of dead trees in swamps and isolated dead branches in open areas, or moves on the ground. It is relatively bold and has a loud voice. Sometimes it flies to towns and villages to hunt. It mainly feeds on small snakes, frogs, lizards, mice, squirrels, hares, foxes, birds and other animal foods, and sometimes eats large insects and animal carcasses. It mainly forages in the morning and evening. The foraging method is mainly to perch on the tops of isolated trees in open areas, staring at the ground with both eyes, and suddenly rush down to pounce on prey when it finds prey. Sometimes it also flies at low altitude to hunt, or wanders back and forth on the ground to find and hunt food.

The breeding season of the Gray-faced Buzzard is from May to July. Nests are built in sparse woodlands near riverbanks in broad-leaved or mixed forests, or in trees in swamp meadows and forest edges in the forests. They are also found nesting in isolated trees at the edge of forest edges. The nests are mostly built on the top branches of trees, 7-15 meters above the ground. The nests are disc-shaped, mainly made of dead branches, with dead grass stems, grass leaves, bark and feathers inside. Each nest lays 3-4 eggs, occasionally as few as 2. The eggs are white with rust or reddish-brown spots.

They appear in large numbers when migrating through Taiwan, China in spring and autumn. When the gray-faced buzzard passes through Taiwan in spring and autumn, the large number of them causes local residents to hunt and resell them for profit, so they face strong pressure.
