Living with the Tide
Heinz Sielmann shows the second of two films on the wildlife of contrasting regions of West Germany. The Watten is a coastal wilderness of mud and sand flats stretching from the Netherlands to Denmark. Twice a day the sea covers it with a blanket of silt, rich in plankton and detritus and supporting an enormous population of shellfish and worms.
This wealth of food ensures that up to 40 million birds find the Watten a very attractive stopping-off point in their migrations. Narrated by DEREK JONES
