One Midsummer's Day

Based on a lifetime of close observation, One Midsummer's Day explores swifts, the natural world and our place in it, in one of our greatest nature writer's most ambitious books to date

It takes a whole universe to make one small black bird

The bestselling author of Crow Country and writer of The Guardian's Country Diary tells the story of all life on Earth through a single day spent in the company of swifts.

'A jewel of a book' Caroline Lucas MP

Swifts are among the most extraordinary of all birds. Their migrations span continents and their twelve-week stopover, when they pause to breed in European rooftops, is the very definition of summer. They may nest in our homes but much about their lives passes over our heads. No birds are more wreathed in mystery. Captivated, Mark Cocker sets out to capture their essence.

Over the course of one day in midsummer he devotes himself to his beloved black birds as they spiral overhead. Yet this is also a book about so much more. Swifts are a prism through which Cocker explores the profound interconnections of the whole biosphere.

From the deep-sea thermal vents where life was born to the 15 million degrees at the core of our Sun, he shows that life is a singular and glorious continuum. These birds without borders are a perfect symbol to express the unity of the living planet. But they also illuminate how no creature, least of all ourselves, can be said to be alive in isolation. We are all inextricably connected.

Drawing deeply on science, history, literature and a lifetime of close observation, One Midsummer's Day is a dazzling and wide-ranging celebration of all life on Earth by one of our greatest nature writers.
