The equivalent of our Sea Eagle is the White-headed or Bald Eagle of America, the female of which is the same length as the male of our Eagle, 38 inches. Many of these glorious Sea Eagles were floating, with their peculiar butterfly-like flight, over the Brisbane River, and added much to our enjoyment of a recent bird excursion there. We found one nest on each island in the Capricorn Group. On Mast Head Island the nest was in a tree about 60 feet high. On tiny Erskine Island, where there were no big trees, it was built on the ground, though it had been added to until it is now over 6 feet high. The fully-feathered dark-brown young bird sat on the edge of the nest, and formed a good photographic subject. Eagles were ruthlessly slaughtered in the British Isles. There is a shadow of an excuse there, perhaps, with their game preserves, where rabbits and birds are bred for sporting purposes. These reasons do not exist here. But it is pleasing to find on record that, even there, "Lord Breadalbane, who died in 1862, thought that the spectacle of a soaring Eagle was a fitting adjunct to the grandeur of the Argyllshire mountain scenery, and a good equivalent for the occasional loss of a lamb." Though the Sea Eagle lives mainly on fish and refuse cast up by the sea, it is pitiful to read that, though this interesting, picturesque, and valuable bird was once common, not one is left on the mainland of Scotland. Could blind, unreasoning slaughter do more? Why kill a harmless bird? But it is not only harmless; it is of distinct value in its sphere in Nature. Hawks altogether are misunderstood and misjudged. It is doubtful if it pays a farmer, aye, even a poultry farmer, to shoot Hawks. They might steal a few chickens, but they do not live on them. They live mainly on rabbits, mice, rats, and insects. The Whistling Eagle whistles while flying about in the fine large flight-houses of the Adelaide Zoological Gardens. One fine specimen accompanied the Federal trawler _Endeavour_ down Gladstone Harbor, but not far from shore, for it returned when we headed for the open ocean and the fairyland of the Great Barrier Reef. Kites used to be excessively common about many English towns, where they acted as scavengers. The introduction of the shot-gun has exterminated them. They are world-wide in distribution, so what you read about European Kites will fit Australian Kites. They are, perhaps, the most graceful of flyers, gliding, soaring, hovering, and performing all sorts of aërial evolutions. The toy kites of our childhood were suggested by the flight of these once common birds. Now, alas! they are very rarely seen. Being mainly insectivorous, they are invaluable birds, and we can ill spare them in this country, where insect life is so abnormally prolific. The Black-breasted Buzzard is the third largest of our Diurnal Birds of Prey. It is a rare visitor in Southern Australia, but in seasons of drought it comes down from Central Australia.
