As one of the first migrants, its song can be heard already in mid-March. A few birds try regularly to spend the winter in Switzerland, especially near water. The Common Chiffchaff is not so particular in choosing its territory and inhabits almost any woodland up to the treeline. It is one of our most widespread breeding birds. The female is responsible for building the domed cup nest, for which it requires at least 1200 flights."}
