Finally summer is here and we may enjoy the scream of the aerial acrobats - the common swifts - from our hammocks or garden coffee tables. To further enlighten the summer holiday I wish to recommend a paper in the most recent issue of the eminent popular science journal Forskning & Framsteg. The publication will be a challenge for non-native Swedish speakers, as it is published in Swedish, but I suggest a try. In this paper Anders and I describe recent findings of movement studies of the common swift - a true aerial migrant. For instance in a lifetime the common swift may cover 7 journeys to the moon and back!
