A few words on the latest attempt which has been made to naturalize an exotic bird in England will not seem out of place here. About eight years ago a gentleman in Essex introduced the rufous tinamou--a handsome game bird, nearly as large as a fowl--into his estate. Up till the present time, or till quite recently these birds have bred every year, and at one time they had increased considerably and scattered about the neighbourhood. When it began to increase, the neighbouring proprietors and sportsmen generally were asked not to shoot it, but to give it a chance, and there is reason to believe that they have helped to protect it, and have taken a great interest in the experiment. Whatever the ultimate result may be, the partial success attained during these few years is decidedly encouraging, and that for more reasons than one. In the first place, the bird was badly chosen for such an experiment. It belongs to the pampas of La Plata, to which it is restricted, and where it enjoys a dry, bright climate, and lives concealed in the tall close-growing indigenous grasses. The conditions of its habitat are therefore widely different from those of Essex, or of any part of England; and, besides, it has a peculiar organisation, for it happens to be one of those animals of ancient types of which a few species still survive in South America. That so unpromising a subject as this large archaic tinamou should be able to maintain its existence in this country, even for a very few years, encourages one to believe that with better-chosen species, more highly organized, and with more pliant habits, such as the hazel hen of Europe for a game bird, success would be almost certain.
