For many, birdwatching is a green use of leisure time, with increasing appeal as they potter into retirement. But some start young, watching birds with obsessional and lifelong devotion. Mark Cocker, a member of this clannish fraternity and a regular Guardian Country Diarist, weaves autobiography, anecdote, fact and reflection in a winning attempt to capture the appeal and the lore of this popular pursuit. He writes well, with refreshing erudition - for example, the school of birding that subscribes to the art of 'jizz' (recognizing a bird at long distance by its essential character rather than by checking off ID features) is related to Gerard Manley Hopkins 'inscape', the 'isness' of things. Birders who work like this are the 'Zen masters' of their craft. An amiable, nostalgic account, tinged with good-humoured irony. But anyone unable to name the birds that settle in their garden will find it about as useful as a freemason's handbook. (Kirkus UK)
