- ルリビタキ

- Class

In the breeding season it stays high in the mountains; in winter it comes down to the lowlands, living in woods and parks with many trees.
Males are blue from the head down the back, while females are olive with just the top of the tail blue. It takes a male a few years to turn a beautiful blue.
It eats insects, earthworms and spiders both in trees and on the ground, and it wags its tail rhythmically.
How the Red-flanked bluetail lives
They use dimmer places in the woods than Daurian redstarts do. They call “hit, hit” and sing “pichu chuririri”. During the breeding season, they live as pairs in the woods.
