Fast and agile during flight, like lightning, in the middle of the time, the drum flying becomes gliding again, and can even "stagnate the air" in the air -this is the natural "hunter".

At dusk, it was the most frequent predation activities of Yan Yan. The air is their hunting ground.

Yan Yan's flying speed is particularly fast, and people are not paying attention to it, even if it flys from her eyes, it is difficult to find. Even home swallows and swallows with extremely fast flight speed are things in their pockets. Dragonflies, 蟋蟀, Tiando, and Golden Turtle are also prey by Yan Yan.

Yan Yan is good at flying on the open field and hunting, but is not good at tracking prey in the dense forest. Generally speaking, people do not see the trace of Yan Yan on the ground. They will eat the prey directly during flight, and most of them are on the tall trees or the top of the wire.

During the hunting, Yan Yan's scream was short, sharp, and harsh. In the breeding season, once there is an invaders approaching the nest, they will also make a loud cry. Only when you ask for a puppet can Yan Yan show a rare gentleness -after pairing, the male birds often have food in the mouth to approach female birds, and then hand over the food to complete the "bow" ceremony between them. Then, the male and female birds flew in the air and sang a soft "love ballad".
