Some birds are easily artificially illuminated and don’t know when to sleep. Many songbirds suffer from insomnia in areas where the city is brightly lit at night. Everyone who knows a pet bird knows that as long as a blanket is placed on the bird cage to create a dark night environment, the bird will soon fall asleep. It is also very simple to let the bird fall asleep. You can get close to the bird cage and pick up your eyes, like the eyes of a pair of hypnotists, that is, make a sleepy look, “eyes are getting heavier” (don’t talk), as if you are going to sleep. At this time, your bird will follow you to sleep. It lifted a foot under the abdomen, curled its head under the wings, and quickly fell asleep.
