What birds should Beijing Botanical Garden have in March 1, 20 19?

Wren in Beijing Botanical Garden became friends with people and often sang in front of them. This song is not very euphemistic, but it is very loud. Sometimes it will jump 3-4 meters away from people, which is the result of no one hurting it after feeding it often and trusting people. Wren is about 10 cm long and lives by streams in forests and bushes.
