We keep the square to ourselves! An ornithologist told us what is the best way to feed birds in winter and whether it is still possible to treat birds with bread. Contrary to speculation, bread, including white bread, by itself will not harm birds. Only the salt in its composition can pose a danger. The most suitable food for urban birds is not roasted sunflower seeds. These are the ones that need to be poured into the feeders. Let's remember and go do a good deed.
