Bands of adult birds and their young zoom about high above chasing each other and twittering loudly in their aerial displays. The large falcon-like Alpine Swifts occur in two different habitats in our country: They breed in cliffs in the Alps and regionally in the Jura Mountains. They have also ventured into towns and cities where high buildings provide them with further breeding sites.
