"The arrival of the swallows means that spring is beginning..." But where were the swallows before that, what did they do in winter? The biologist Pavel Kvartalnov tells about the hatching and growing up of a swallow in Ireland, about its long migration via Paris, Madrid and Marrakesh, about the dangers lurking on the way. He tells of wild animals that she encounters on the way and the sea that she has to cross. And all the hardships only to fly all the way back in the end and build a nest in their Irish homeland.
