A series of nine programmes featuring natural history films from other countries. Trumpeter Blues
With a call which sounds like old, resonant brass, the trumpeter swan, or bugler, was once a familiar sight in North America.
At the turn of the century it was almost extinct. Through careful management, its numbers have risen to around 5,000. But, curiously, all is not well for the trumpeter - many are dying, and no-one knows why. Bob Landis , a North
American film-maker, spent two years in the Yellowstone National Park pursuing these magnificent birds and trying to discover why they are in trouble.
This film won an award for photography at this year's Missoula Film Festival in Montana.
