It must not be thought that this beautiful warbler confines itself to backyards in the city of Nashville simply because Wilson discovered it near there and gave it a local name, for the bird's actual range reaches from the fur trader's camp near Hudson Bay to the adobe villages of Mexico and Central America, and over two thousand miles east and west in the United States. It chooses open rather than dense woods and tree-bordered fields. It seems to have a liking for hemlocks and pine trees, especially if near a stream that attracts insects to its shores; and Dr. Warren notes that in Pennsylvania he finds small flocks of these warblers in the autumn migration, feeding in the willowy trees near little rivers and ponds. Only in the northern parts of the United States is their nest ever found, for the northern British provinces are their preferred nesting ground. One seen in the White Mountains was built on a mossy, rocky edge, directly on the ground at the foot of a pine tree, and made of rootlets, moss, needles from the trees overhead, and several layers of leaves outside, with a lining of fine grasses that cradled four white, speckled eggs.
Audubon likened the bird's feeble note to the breaking of twigs.
PINE WARBLER (Dendroica vigorsii) Wood Warbler family Called also: PINE-CREEPING WARBLERLength -- 5.5 to 6 inches. A trifle smaller than the English sparrow.
Male -- Yellowish olive above; clear yellow below, shading to grayish white, with obscure dark streaks on side of breast. Two whitish wing-bars; two outer tail feathers partly white.
Female -- Duller; grayish white only faintly tinged with yellow underneath.
Range -- North America, east of the Rockies; north to Manitoba, And south to Florida and the Bahamas. Winters from southern Illinois southward.
Migrations -- March or April. October or later. Common summer resident.
The pine warbler closely presses the myrtle warbler for the first place in the ranks of the family migrants, but as the latter bird often stays north all winter, it is usually given the palm. Here is a warbler, let it be recorded, that is fittingly named, for it is a denizen of pine woods only; most common in the long stretches of pine forests at the south and in New York and New England, and correspondingly uncommon wherever the woodsman's axe has laid the pine trees low throughout its range. Its "simple, sweet, and drowsy song,"writes Mr. Parkhurst, is always associated "with the smell of pines on a sultry day." It recalls that of the junco and the social sparrow or chippy.
Creeping over the bark of trees and peering into every crevice like a nuthatch; running along the limbs, not often hopping nervously or flitting like the warblers; darting into the air for a passing insect, or descending to the ground to feed on seeds and berries, the pine warbler has, by a curious combination, the movements that seem to characterize several different birds.
It is one of the largest and hardiest members of its family, but not remarkable for its beauty. It is a sociable traveller, cheerfully escorting other warblers northward, and welcoming to its band both the yellow redpolls and the myrtle warblers. These birds are very often seen together in the pine and other evergreen trees in our lawns and in the large city parks.
PRAIRIE WARBLER (Dendroica discolor) Wood Warbler family Length -- 4.75 to 5 inches. About an inch and a half shorter than the English sparrow.
Male -- Olive-green above, shading to yellowish on the head, and with brick-red spots on back between the shoulders. A yellow line over the eye; wing-bars and all under parts bright yellow, heavily streaked with black on the sides. Line through the eye and crescent below it, black. Much white in outer tail feathers.
Female -- Paler; upper parts more grayish olive, and markings Less distinct than male's.
Range -- Eastern half of the United States. Nests as far north as New England and Michigan. Winters from Florida southward.
Migrations -- May. September. Summer resident.
Doubtless this diminutive bird was given its name because it prefers open country rather than the woods -- the scrubby undergrowth of oaks, young evergreens, and bushes that border clearings being as good a place as any to look for it, and not the wind-swept, treeless tracts of the wild West. Its range is southerly. The Southern and Middle States are where it is most abundant. Here is a wood warbler that is not a bird of the woods -- less so, in fact, than either the summer yellowbird (yellow warbler) or the palm warbler, that are eminently neighborly and fond of pasture lands and roadside thickets. But the prairie warblers are rather more retiring little sprites than their cousins, and it is not often we get a close enough view of them to note the brick-red spots on their backs, which are their distinguishing marks.
They have a most unkind preference for briery bushes, that discourage human intimacy. In such forbidding retreats they build their nest of plant-fibre, rootlets, and twigs, lined with plant-down and hair.
The song of an individual prairie warbler makes only a slight impression. It consists "of a series of six or seven quickly repeated tees, the next to the last one being the highest" (Chapman). But the united voices of a dozen or more of these pretty little birds, that often sing together, afford something approaching a musical treat.
