Its nest is usually built in cone-bearing trees at a variable altitude of from three to thirty feet. These homes are neatly woven and usually constructed of fine strips of bark, pine needles and twigs. They are lined with fine roots, bark fibers, hair and feathers. In Colorado it is known to breed on the mountain sides at an altitude of nine or ten thousand feet. The habits of this little warbler are well portrayed by Mrs. Whitman: The little bird upon the hillside lonely, Flits noiselessly along from spray to spray. THE SING-AWAY BIRD. Have you ever heard of the sing-away bird, That sings where the run-away river Runs down with its rills from the bald-headed hills That stand in the sunshine and shiver? Oh, sing, sing away, sing away! How the pines and the birches are stirred By the trill of the sing-away bird! And beneath the glad sun, every glad-hearted one Sets the world to the tune of its gladness; The swift rivers sing it, the wild breezes wing it, Till earth loses thought of her sadness. Oh, sing, sing away, sing away! Oh, sing, happy soul, to joy’s giver— Sing on, by Time’s run-away river. —Lucy Larcom. [Illustration: AUDUBON’S WARBLER. (Dendroica auduboni.) ⅗ Life-size. FROM COL.
