In recent years, starlings have shifted to roosting in cities, where they are closer to people, causing problems such as noise and fecal damage. In this proposal, we investigate the spaces where starlings tend to roost, and create roosting spaces in cities where they can live separately from people. As a result, the starlings can move to the new roosting area and reduce the damage to humans. In addition, by using the bird's seed-carrying ability to regenerate the environment and create green spaces in urban spaces, we can make people aware that starlings are beneficial to urban ecosystems and enable starlings to coexist with people.
