Instead of the scarlet and summer tanagers, the Rocky Mountain region is honored with that beautiful feathered gentleman, the Louisiana tanager, most of whose plumage is rich, glossy yellow, relieved by black on the wings, back, and tail; while his most conspicuous decoration is the scarlet or crimson tinting of his head and throat, shading off into the yellow of the breast. These colors form a picturesque combination, especially if set against a background of green. The crimson staining gives him the appearance of having washed his face in some bright-red pigment, and like an awkward child, blotched his bosom with it in the absence of a napkin.
So far as I could analyze it, there is no appreciable difference between his lyrical performances and those of the scarlet tanager, both being a kind of lazy, drawling song, that is slightly better than no bird music at all. One nest was found without difficulty. It was placed on one of the lower branches of a pine tree by the roadside at the entrance to Engleman's Cañon. As a rule, the males are not excessively shy, as so many of the Rocky Mountain birds are. The tanagers were seen far up in the mountains, as well as among the foothills, and also at Red Cliff and Glenwood on the western side of the Divide.
A unique character in feathers, one that is peculiar to the West, is the magpie, who would attract notice wherever he should deign to live, being a sort of grand sachem of the outdoor aviary. In some respects the magpies are striking birds. In flight they present a peculiar appearance; in fact, they closely resemble boys' kites with their long, slender tails trailing in the breeze. I could not avoid the impression that their tails were superfluous appendages, but no doubt they serve the birds a useful purpose as rudders and balancing-poles. The magpie presents a handsome picture as he swings through the air, the iridescent black gleaming in the sun, beautifully set off with snowy-white trimmings on both the upper and lower surfaces of the wings. On the perch or on the wing he is an ornament to any landscape. As to his voice--well, he is a genuine squawker. There is not, so far as I have observed, a musical cord in his larynx,[2] and I am sure he does not profess to be a musical genius, so that my criticism will do him no injury. All the use he has for his voice seems to be to call his fellows to a new-found banquet, or give warning of the approach of an interloper upon his chosen preserves. His cry, if you climb up to his nest, is quite pitiful, proving that he has real love for his offspring. Perhaps the magpies have won their chief distinction as architects. Their nests are really remarkable structures, sometimes as large as fair-sized tubs, the framework composed of good-sized sticks, skilfully plaited together, and the cup lined with grass and other soft material, making a cosey nursery for the infantile magpies. Then the nest proper is roofed over, and has an entrance to the apartment on either side. When you examine the structure closely, you find that it fairly bristles with dry twigs and sticks, and it is surprising how large some of the branches are that are braided into the domicile. All but one of the many nests I found were deserted, for my visit was made in June, and the birds, as a rule, breed earlier than that month. Some were placed in bushes, some in willow and cottonwood trees, and others in pines; and the birds themselves were almost ubiquitous, being found on the plains, among the foothills, and up in the mountains as far as the timber-line, not only close to human neighborhoods, but also in the most inaccessible solitudes.
