Naturalist Mark Cocker has always been fascinated by swifts, and in One Midsummer’s Day he sets out to discover their essence. Migrating swifts span continents and their 12-week stopover with us is the definition of summer. These birds without borders are a metaphor to express the unity of the living planet, for no creature, least of all ourselves, can live in isolation. Fellow wildlife enthusiast Hamza Yassin’s book Be a Birder is a joyful guide for beginners. The wildlife cameraman (and Strictly 2022 winner) explains how to identify birds quickly, understand bird behaviour and choose the right equipment. Born in Sudan, living in Scotland, Yassin’s first TV appearance was as Ranger Hamza on the CBeebies show Let’s Go for a Walk and he is a presenter on BBC One series Animal Park. They talk to broadcaster and author Kate Humble.
