Plate XVIII.—DENDROECA DISCOLOR, Baird.—Prairie Warbler.
The Prairie Warbler is nowhere an abundant species. Throughout the eastern parts of the United States, from Massachusetts to Georgia, it is pretty generally, though somewhat irregularly, diffused. It is also found in Kansas, according to Mr. Allen, although unobserved by Dr. Coues in his western explorations.
Audubon claims to have met it in Louisiana, but his description of its nesting is so palpably inaccurate, that we are compelled to accept his statement with misgivings. Wilson obtained specimens in Kentucky, and to him the species is indebted for the very inappropriate appellation by which it is known. Nuttall regarded it a rare visitor in the New England States, yet subsequent observations do not confirm his opinion, but show, in Massachusetts especially, that it is rather common. In Eastern Tennessee and Northern Georgia, in the summer of 1880, Mr. Alexander M. Reynolds, of Germantown, Pa., met with numerous individuals, which had probably bred in those regions, but no nests were taken.
Although the town of Lynn, Mass., in latitude 42° 30', had hitherto been accepted as the northern limit of its breeding, yet it was reserved for H. D. Minot, Esq., to prove that the species often reached the latitude of Mt. Washington, nearly three degrees further north. Future explorations will doubtless show that its vernal migration often surpasses this limit, and reaches even to the Canadian dominions.
In the Middle Atlantic States the writer has obtained specimens early in May, and has observed in Southern New Jersey, and elsewhere, young birds just able to fly, but could never discover auy nests. Mr. Jolin Cassin, in his day, expressed the opinion that these birds certainly bred in the same State, near Philadelphia, as he frequently met with the young under similar circumstances. Nests have been taken in Central New York, but we have no evidence of its breeding in the adjoining State of Pennsylvania, although individuals have been seen in transitu.
Though chiefly a migrant in the United States, yet a few winter in Florida. But the larger part cross the Channel, after the breeding-season is over, and spend their time in the delightful islands which lie to the southward. Here, in January, these once beautiful birds may be seen in their winter garb sporting amid tropical or sub-tropical foliage, or hunting the insects that contribute to their bill of fare.
About the beginning of April, sometimes later, they deck themselves in their summer array, and while some sojourn in these Isles of the Blest where summer is perennial, and raise their charming little families, others pine for the cooler groves and fields of the North. Accordingly, about the tenth of April, all things being in readiness, and at a season when Nature is weeping herself away in rainy tears, the males apparently leading the way, the sexes bid adieu to the sights about them, and take their departure.
