“For the sake of their song as well as beauty of plumage they are commonly domesticated in the houses of the French inhabitants of New Orleans and its vicinity. . . .
“They are commonly caught in trap-cages, to which they are sometimes allured by a stuffed bird, which they descend to attack; and they have been known to live in captivity for upwards of ten years.”—Thomas Nuttall.
“The Mockingbird, as you see, has sombre gray plumage like his cousin, the Catbird, that we all know so well that I think he should drop a name that belies his wonderful musical ability, and be called the ‘Northern Mockingbird.’ Even though the Mocker is caged, you can see the resemblance, in the way in which he twitches his tail, and first throws back his beak and then looks sideways, to our merry singer of the garden who often makes us think that half a dozen birds are perching in the drying-yard when he sits upon the top of a clothes-pole and lets his imagination float away with his voice.
“The Brown Thrasher, too, with the long, curved beak, brown back, and speckled breast, is also a first cousin and has the Mockingbird habit of mounting high up when he sings and looking straight up at the sky; while the Wrens, one and all, belong to this famous family group and come in, we may say, as second cousins, and like the Mockingbird, aside from the beauty of song, are very valuable insect eaters. The other three birds have the conical beak that stamps them as members of the family of Finches and Sparrows.
“Rich colour is the chief attribute that sets the Indigo Bunting apart from its kin of the tribe of Sparrows and Finches.
“Blue that is decided in tone, and not a bluish gray, is one of the rarest hues among the birds of temperate zones; for one may count the really blue birds of the eastern United States upon the fingers of one hand.
“This Bunting belongs to the tree-loving and tree-nesting part of his tribe, in company with the Grosbeaks, and the brilliant yellow American Goldfinch, whose black cap, wings, and tail-feathers only enhance his beauty. The Sparrows, of sober stripes, nest on or near the ground, and their plumage blends with brown grass, twigs, and the general earth-colouring, illustrating very directly the theory of colour protection, while the birds of brilliant plumage invariably keep more closely to the trees.
“In size the Indigo Bunting ranks with the small Sparrows, coming in grade between the Field- and the Song Sparrows, and being only slightly larger than the Chippy. The female wears a modification of the Sparrow garb, the upper parts being ashy brown without stripes, the underparts grayish white, washed and very faintly streaked with dull brown, the wings and tail-feathers having some darker edges and markings.
“When it comes to painting the plumage of the male in words, the task becomes difficult; for to use simply the term indigo-blue is as inadequate as to say that a bit of water that looks blue while in shadow, is of the same colour when it ripples out into full sunlight and catches a dozen reflections from foliage and sky. A merely technical description would read: Front of head and chin rich indigo-blue, growing lighter and greener on back and underparts; wings dusky brown, with blue edges to coverts; tail-feathers also blue edged; bill and feet dark; general shape rounded and canary-like, resembling the Goldfinch.
“The last of May one of these Buntings came to a low bush, outside my window, and, after resting awhile, for the night before had been stormy, dropped to the closely cut turf to feed upon the crumbs left where the hounds had been munching their biscuits. I have never seen a more beautiful specimen, and the contrast with the vivid grass seemed to develop the colour of malachite that ran along one edge of the feathers, shifting as the bird moved like the sheen of changeable silk.
