The delights of Jamaica as a holiday playground are familiar enough, but what does the island offer to the naturalist? Last year a party of Oxford zoologists and film-makers spent a long vacation there, and the results can be seen today and next Sunday.

The leader of the expedition was Gerald Thompson, well known for his films of insect behaviour, and the programme will include outstanding film both by him and by Peter Parks, who, using a special photographic method, has produced some of the most remarkable close-ups of minute animal life yet seen on television.
