A CURIOUS SURVIVAL.
ELLA F. MOSBY.
THE tongue of a bird, says Mrs. Olive Thorne Miller, is the tool that shows how he gets his living, as the anvil and hammer tell of the blacksmith's work, the hod of the bricklayer's, and the chisel and plane of the carpenter's. The tongue of the woodpecker is a barbed spear, very adhesive or sticky on its surface. We know at a glance that he uses it to capture insects hiding in the crevices of the bark, and if they are too small to be speared by its sharp point, they will stick to its gluey surface. "The four-tined fork" of the little nuthatch is admirable for catching grubs out of the rough tree-trunk, and the slender tube of the humming-bird's tongue proves him a dainty taster of flower-sweets, though he, too, catches insects, with a click of his long, sharp bill as he flies, when flowers are rare. But there is a small bird whose tongue does not tell his own story. His tropical ancestry of many and many a year ago, like the humming-bird, sucked honey from flower-cups and juices from fruits, and so by a very curious survival of structure, this Cape May warbler that feeds on insects now has the tongue cleft at the tip and provided with a fringe like the iridescent and shining sunbird's, the honey-creeper's and flower-pecker's of southern isles. Their tongues, "pencils of delicate filaments," brush the drops of honeyed nectar from the deep tubes of tropic flowers and their sharp, needle-like bills probe the juicy fruits, though, like humming-birds, they adds small insects to their bill of fare when necessary.
This peculiarity on the part of the Cape May is the more curious because all the warblers, numerous as these are and varying as widely as possible in character, plumage and habits, are alike in one respect—they are insect-eaters. Whether they are ground warblers or haunt river side and stream or explore trunk, branch, and twig-like creepers, or glean their food from the leaves, or resemble the flycatchers in habit, they live on insects, flies, ants, canker-worms, caterpillars, gnats, the larvæ and eggs of insects; nothing of this sort comes amiss to them. Some warblers seek this food in the tree-tops, and rarely descend; others feed on the ground and build their nests there. Many frequent lower boughs and shrubs, but all seek insects as their prey. A few, it is true, like the eccentric chat and the pretty gold-crowned thrush, who is not a thrush after all, in spite of his speckled breast, are very fond of berries. But none retain the honey-sucking habits for which the tube-like and fringed tongues, and keen, needle-like bills, were fashioned.
There is also a queer coincidence between the nest-making of the Cape May warbler and that of the flower-peckers in the Philippines Islands—another curious survival. Mr. John Whitehead, the naturalist and explorer, found a most exquisite rose-colored pouch, which looked as if formed of rose-petals, though it was in fact made of other material. The little honey-sucker had woven it together with the silken threads of a spider's web. Now, the Cape May warbler weaves his partly hanging nest of twigs and grass, and lines it with horsehair in the great fir woods of the north, but he, too, fastens it together with spider's webbing.
