Roof on the Moonway

In the early 1980s, two hundred pairs of Common Terns (Sterna hirundo) were forced to abandon their last natural nesting place on a river island near the major European capital, Riga. Looking for a new habitat, the birds chose the flat pebbled roof of a concrete island - a printing house - in the middle of the city. The first generation of birds to grow up on this roof and fly to Southern Africa every winter have covered the distance from the Earth to the Moon. During the film various human attitudes towards the terns will emerge. The attitude of the birds is clear - they view things from above.
