In Wild Air, James Macdonald Lockhart sets out to write about a series of birds as though he has his granny's role of listening to birds' songs and calls and relaying what she heard to her aged and by then quite deaf father - the famous naturalist Seton Gordon. From a nightjar's strange churring song on a heath in the south of England, to a lapwing displaying over the machair in the Outer Hebrides, he writes about eight different birds who he has spent most time with, returned to most often and relays what he hears.
