Our survey of marine ornithology can scarcely be considered complete without a brief allusion to the various land birds that reside upon the coast. Many of these birds are, perhaps, most closely associated with inland districts, but others are just as essentially marine. Some of these species constantly reside by the sea, others are but found there during the bright summer days, whilst others yet again appear during autumn and winter only. Be the shore low sand or marshy slob-land, buttressed by precipitous cliffs, or fringed with rocky beaches and open downs, certain land birds form decided features in the scene, some of them very widely and very generally dispersed. In some cases these species show us how very readily birds can adapt themselves to their surroundings, or reconcile themselves to circumstances, finding as congenial a home on the seaboard as in the woods or fields, or even cities of the interior. WHITE-TAILED EAGLE. Half a century ago this fine bird, the _Haliaetus albicilla_ of ornithologists, was very generally distributed round our northern coasts; in earlier years than that it bred in certain parts of England, possibly on most of our highest headlands. Trap, gun, and poison have done their sad work only too well, and now the White-tailed Eagle is banished almost entirely from the land. The birds that still survive are mostly confined to the Hebrides, to the wild waste of islands and sea along the western seaboard of Scotland. Occasionally stray birds are noticed, during autumn and winter, on the coast of England, but these are almost invariably immature individuals on their migration south. The White-tailed Eagle almost exclusively frequents maritime districts, where it may be seen at a vast height soaring on never-tiring wing, or standing on some rock pinnacle. It preys upon every bird or animal that it is able to capture—newly-dropped lambs and fawns, hares, rabbits, grouse, and waterfowl. But its favourite fare, perhaps, is carrion—stranded fish and other garbage on the shore, dead sheep, and so on. This Eagle makes its eyrie on some stupendous ocean cliff, and, as the birds pair for life, the spot is occupied years in succession. The nest is a huge pile of sticks and branches, lined with dry grass, wool, and other soft material. The two eggs, laid in March or April, are white. This Eagle may be distinguished from the Golden Eagle by its bare tarsi. The note is a yelping or barking cry. Outside our limits, this bird is found in the northern portions of Europe and Asia, from the Atlantic to the Pacific. PEREGRINE FALCON.
