In reference to this bird’s adaptability to acclimatisation in our own country, it appears to me to be most admirably fitted for our hill and moorland districts. It is very hardy, capable of bearing a temperature of 30° to 33° below zero; feeds on seeds, berries, and vegetable matter—in every particular analogous to what it could find in our own hill-country; a good breeder, having usually from twelve to fourteen young at a brood; nests early, and would come to shoot about the same time as our own grouse. Snow does not hurt them in the slightest degree; they burrow into it, and feed on what they can find underneath it. The two specimens in the British Museum I shot in the Colville valley; they are male and female, in winter plumage; and anyone, who may feel an interest in getting these birds brought home, may there see for himself what fine handsome creatures they are. But then comes the question—how are they to be obtained, and how brought to England? I do not imagine it would be a very difficult or expensive matter; the young birds in May could be easily obtained, at any point up the Columbia river, by employing the Indians to bring them to the riverside; and once on board steamer, they could be as easily fed as fowls. The great difficulty _I_ have always had is in bringing the young birds from the interior to a vessel; they always die when transported on the backs of animals, however carefully packed. The continued jerking motion given to birds packed on the back of a mule or horse as he walks along has, according to my experience, been the sole cause of their dying ere you could reach water-carriage; but the fact of their being so close to water as they are along the Columbia river, would render their being brought home a very easy task. THE BALD-HEADED EAGLE (_Haliactus leucocephalus_) is seen but seldom, as during its breeding-time it retires into the hills, and usually chooses a lofty pine as its nesting-place. Two of them had a nest near the Chilukweyuk lake, which was quite inaccessible, of immense size, and built entirely of sticks—the same nest being invariably used year after year by the same pair of birds. Their food consists mainly of fish, and it is a curious sight to watch an eagle plunge into the water, seize a heavy salmon, and rise with it without any apparent difficulty. Both the osprey and bald-headed eagle fish with their claws, never, as far as I have observed them, striking at a fish with the beak; during winter they collect, young and old together, round the Sumass lake; and as the cold becomes intense, they sit three and four on the limb of a pine-tree, or in a semi-stupid state, all their craft and courage gone, blinking and drowsy as an owl in daytime.
