‘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.
