Birds on migration

The first programme in the new series of Saving Species is scheduled to include a feature on the migration of swallows. During the winter a Natural History Unit team visited Nigeria to track down a little-known population of wintering swallows - and they found them. At the time this programme is broadcast, most of those birds will be in their European breeding grounds, including a considerable number in the UK.
