It only remains to add something on another subject--the little life-histories of the two hundred and odd species described in this volume. Although this is in no sense a controversial subject, the apologetic tone must be still used. I wish that these sketches had been better done, but I do not greatly regret that they had to be brief. The longest history of a bird ever written, the most abounding in facts and delightful to read, when tested in the only sure way--namely, by close observation of its subject--is found to be scarcely more complete or satisfactory than the briefest, which contains only the main facts. This is because birds are not automata, but intelligent beings. Seebohm has well said, ‘The real history of a bird is its _life_-history. The deepest interest attaches to everything that reveals the little mind, however feebly it may be developed, which lies behind the feathers.’ It has been remarked more than once that we do not rightly appreciate birds because we do not see them well. In most cases persecution has made them fearful of the human form; they fly from us, and distance obscures their delicate harmonious colouring and blurs the exquisite aërial lines on which they are formed. When we look closely at them, we are surprised at their beauty and the indescribable grace of their varied motions. An analogous effect is produced by a close observation of their habits or actions, which, seen from afar, may appear few and monotonous. Canon Atkinson, in his ‘Sketches in Natural History’ (1865), has a chapter about the partridge, prefaced by Yarrell’s remark, that of a bird so universally known there was little that was new to be said. While admitting the general truth of this statement, the author goes on to say: ‘Still, I have from time to time observed some slight peculiarity in the habits of the partridge that I have not seen noticed in any professed description of the bird, forming certain passages, as it were, of its minute history. It is precisely this ‘minute history’ that gives so great and enduring a fascination to the study of birds in a state of nature. But it cannot be written, on account of the infinity of ‘passages’ contained in it, or, in other words, of that element of mind which gives it endless variety.
