SHEARWATERS
A deceptively drab sea-bird that performs dazzling feats of navigation and endurance, the Manx shearwater breeds in underground nests on islands off the west coast of Great Britain. On the island of Skokholm, R. M. Lockley, noted British naturalist and author, studied the Manx shearwater in twelve years of meticulous observation. The outcome of this now famous research is Shearwaters, a faithful, painstaking record of the breeding and migration habits of this incredible bird. Delightfully written and scientifically scrupulous, Shearwaters is a major contribution to ornithology.
