"Since early boyhood [Ian Naill] has spent much of his time in exploring country places. And of all of them he loves best the tidal estuary where the sea sweeps up to impose its pattern on life in the river and on its banks. there the oyster-catcher stalks the mud, stabbing it with his long beak in search of food,while the heron fishes from the shallows. Ian Niall is a keen fisherman and has much to say about life in the river and stream. But his eyes are not always on the water; he is a bird-watcher too." A good read as always. Chapters include; the nature of river and marsh; the call of the wild goose; duck haunts; waterbirds and waterside birds; the elusive otters; estuary fish; migratory fish; the world of freshwater sharks; stay at home fish. This is one title in a set of four: Wild Life of Field and Hedgeside, Wild Life of Moor and Mountain, Wild Life of River and Marsh, and, Wild Life of Wood and Spinney.
