But the little Golden-crowned Kinglet, a mere mite of flesh and feathers, but with a great deal of spirit, builds a much handsomer nest. It is the perfection of symmetry. Man could not make with all the appliances at his command any thing more nearly globular. But its beauty! It looks like a ball of green moss, the delicate patches of moss being so artfully arranged as to completely hide the dry stems of grasses that constitute the walls. No moss ever spread itself over the ground, or over a stump or tree-trunk, more evenly. When it is known that this Kinglet builds its nest among the slender feathered branches of the hemlock spruce, there is manifestly a reason for the fern-like tracery upon the exterior, so necessary for the preservation of its home. Such a handsome and imposing structure would be far from complete were the inside not in keeping with the outside. But the birds have left nothing to be desired in this particular. The softest and purest of down lines the little bed-chamber, and even swells in its lightness till ready to overflow the neat circular door-way. [Illustration: GOLDEN-CROWNED KINGLETS. Nest the Perfection of Beauty and Symmetry.] Perhaps the most graceful thing you may ever expect to find when on the quest, fitted to be considered the work of the fairies, is the pretty lace hammock of the Parula Warbler. You must search for it early in June, in remote but thin woods, but never far from running water. Often you will see it upon a branch overhanging a stream. The slender twig of a birch is sometimes chosen for its suspension, the terminal spray of a hemlock spruce, or a horizontal branch of a white oak. Like a watch-pocket, with the opening in the side, it is lightly suspended. It is made of a delicate lace-work, the grayish-green usnea moss, that grows on old trees. The whole fabric is the work of two little birds with slate-blue backs and yellow breasts. No other bird of our fauna builds a nest akin to its swinging, eery nest. It is true much of the material is found in position when the builders commence their labor, but the exquisite outline and finish, as well as the cozy interior, are due to the skill of the birds themselves. Even when the structure is just so far completed that occupancy by the female is possible, the male never wearies of its adornment by additional filaments of usnea brought from a distance. He is the happiest of fellows, for his little beak always finds something to do while his patient wife is busy with the duties that lead to maternity. [Illustration: LACE HAMMOCK OF PARULA WARBLER.
