THE AUDUBON’S WARBLER. (Dendroica auduboni.)
Reading edition
Audubon’s Warbler bears the same relation to the Western United States that the myrtle warbler bears to the Eastern States. It inhabits the forests and thickets of the West from British Columbia southward as far as Guatemala in winter. And, as Dr. Coues has stated, it has rarely been known to pass to the eastward beyond the line of arboreal vegetation, which marks the easternmost foothills and outlying elevations of the Rocky Mountains.
During its migrations it is often associated with the titmouse and the ruby-crowned kinglet. It may be seen skipping about in the tree tops, actively engaged in searching for insects, which it will at times pursue in the air. It may be readily distinguished from the myrtle warbler, which it so closely resembles both in habits and actions, by its yellow instead of white throat, which is characteristic of the myrtle warbler.
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.
