Hannah Stitfall on the Chiffchaff

For wildlife filmmaker and TV presenter Hannah Stitfall, the chiffchaff's song is the first sign of Spring. Each year in March and April she will spend hours following these little birds along the hedgerows trying to get some good shots, watching them feeding from flowering blackthorn, with their beaks covered in pollen. By mid-summer chiffchaffs shift their energy from courtship to preparation, as they will soon be off on their long migration to their wintering grounds. Hannah always listens out for the chiffchaff's last song of the season, before they head back to southern Europe and North Africa.

Presented by Hannah Stitfall and produced by Sophie Anton for BBC Audio Production in Bristol.
