The raven has the reputation, true or false, of being one of the longest-lived birds; certainly it is one of the hardiest, and capable of adapting itself to the greatest extremes of temperature. Its range in the northern hemisphere extends from the regions of ‘thick-ribbed ice’ to the damp, hot woods and burning coasts of Southern Mexico and Central America. The tropical jaguar may help it to a meal at one extremity of its range, the polar bear at the other. Compared to such diversities of climate and of other conditions, those of the British Islands are as nothing. From the Isle of Wight and the southern coast to the northern extremity of Scotland, and beyond, to ‘utmost Kilda’s lonely isle,’ the raven has lived in what, to a bird of his grit, must have been a very pleasant garden with a mild and equable temperature throughout the year. Formerly he was a fairly common bird in all parts of our island, and it is probable that some protection was accorded to him by owners of large estates, in spite of his evil reputation, on account of some such sentiment as now exists with regard to the rook. A pair of ravens in a woodland district, Seebohm says, ‘was often considered the pride and pest of the parish.’ But the sentiment, if it existed, was not strong enough, and the constant persecution of the bird by its two principal enemies, the gamekeeper and the shepherd, joined by a third during the present century in the ‘collector,’ has gradually driven it from all, or well-nigh all, its ancient inland haunts, and it now exists in its last strongholds, the rugged iron-bound sea-coast on the northern coasts of Scotland and the neighbouring islands. A few--a very few--pairs are still to be met with on some of the cliffs on the south and south-west coasts of England, and on the Welsh coast; but even in the rudest and most solitary localities inhabited by it the bird can keep its hold on life only by means of a wariness and sagacity exceeding that of most other wild and persecuted species.
