Every year, millions of birds make incredible journeys across the planet, spanning continents and flying for months on end. We’re used to birds migrating over winter to head towards warmer climes, but we don’t often stop to think about how remarkable this really is.
How does the arctic tern travel from its arctic breeding grounds to its summer home in the Antarctic? And how does the swift stay in the air for ten months at a time?
Writer Mike Unwin and wildlife photographer David Tipling explore this fascinating subject in Flights of Passage, looking into the science behind this bizarre behaviour, accompanied by photos of 67 different species.
Take a look at these stunning photos from the book.
