‘To be recognised and accepted by a peregrine,’ wrote J.A. Baker in 1967, ‘you must wear the same clothes, travel by the same way, perform actions in the same order. Like all birds, it fears the unpredictable.’ Sitting around in the same old clothes, performing chores in the same order, travelling by no way at all, I’ve found comfort in Baker’s assurance that I may at least prove attractive to birds in my slovenly purdah. Sir David Attenborough read The Peregrine beautifully on Radio 4 just before Christmas, but if you were too busy steaming puddings to listen, you may find this a good time for enjoying the series online. I recommend it because, while Baker’s diary begins in October, when the peregrine soars over the fields and flicks acorns ‘like a potter spinning’, it culminates in the most joyful descriptions of spring.
