The cage door is not properly closed and it happens: the bird cage is empty, the budgie has escaped. If the bird is tame and can regularly fly freely and happily, you can attract and bring it back as usual. Here, curling with bird food in your hand usually helps. If it is not tame, it will be more difficult. The first measure is to close all the windows and doors of the apartment so that your budgie cannot fly outside.
Budgerigar escaped: this is important
When the budgie has escaped and the windows are closed, you can start looking for the outlier. Remember that the situation can be very stressful not only for you, but especially for your bird. Therefore, you should try to wait and see. Your bird may fly back into its cage on its own. A capture campaign can strain the relationship of trust between you and your pet. So open the cage and wait.
Capture Bird: Possibilities
The best way to catch an escaped budgie is in the dark. Turn off the lights and carefully approach the bird. Birds just sit around in darkness and don't usually fly around. If you can't catch your flight artist with your fingers, a towel will help. Spread this out between your hands and then carefully (!) Put it over the bird. Then gently wrap the little one in it and put it out of the towel back into the cage.

Vogel flew outside
If your budgie has escaped and has already left the house, the chances of catching it again are very poor. Most birds panic and just fly away. But it may also be that he is still nearby. Search the area, look at trees, roofs and hedges - if you find the outlier, you can try to attract him or catch it with the towel trick.
