How to pair pigeons

Cut two strange pigeons in a cage and separate them with objects in the middle. If one of the pigeons is interested in the other, it will make a "coo" cry. At this time, if the other is also interested, remove the partition and they will mate on their own. If the pigeons are shy, you might as well sprinkle some water on their feathers and let the pigeons comb their own feathers. This will make the other person feel that they are reasonable and help them pair up.
