A series of wild-life programmes.
Introduced by Peter Scott.
During the spring of last year an expedition composed of leading naturalists continued its exploration of the Coto Donana in Southern Spain, one of the most important and most richly populated sanctuaries for wild birds and other animals in Europe.
Tonight, in the first of two programmes dealing with the work of the expedition, Peter Scott invites Guy Mountfort the leader, and Eric Hosking, who directed the photographic work, to show some of the film they made in which several of Europe's rarest birds were photographed for the first time.
