There are many ways to have more birds again in inner cities. Less pollution and poison are part of the solution. Second, increase the food available to birds. Some plants or vegetation is more suited than the other one. Combined with the question of cooling houses in summer and more isolation in autumn and winter, the greening of facades in cities has a simple effect to provide hiding, nesting and feeding spaces for birds. Birds will discover this vegetation as their natural habitat offering relatively safe shelter and food. It is an incredibly simple way to catch 22. Your new shelter is selective in the choice of birds that it will house. Singing birds seem to value the places most. Other predators may follow. At least in late autumn and early winter the energy rich power food is a welcome addition of the diet. Nesting in spring and summer might be another option to have more birds again. We shall need many very small steps again to keep biodiversity or bring back some of it. Birds again is a small initiative.
