Warbler, Sylvia discolor, Aud. Orn. Biog. v. i. p. 76.

      98. 23. Sylvicola montana, Wils. Blue-Mountain Warbler.

      Plate CCCCXXXIV. Fig. 3. Male.

      No bristles at the base of the bill; wings rather short, the third and fourth quills longest; tail much rounded. Upper parts light greenish-olive; a band across the forehead, one over the eye, the cheeks, throat, fore part and sides of neck bright yellow; the rest of the lower parts yellowish-white, the sides marked with narrow longitudinal dusky streaks; wings dusky brown, all the feathers edged with yellowish-white, the secondary quills more broadly, the first row of small coverts and the secondary coverts tipped with white, forming two conspicuous bands; tail brownish-black, the feathers edged with yellowish-green, the two outer on each side white in their terminal half.

      Blue Mountains. Only one individual seen.

      Blue-Mountain Warbler, Sylvia montana, Wils. Amer. Orn. v. v. p. 113.

      Sylvia tigrina, Bonap. Syn. p. 83; but not of Gmelin or Latham, as the figure of Edwards, to which reference is made, has the tail not rounded, but emarginate.

      99. 24. Sylvicola agilis, Wils. Connecticut Wood Warbler.—Connecticut Warbler.

      Plate CXXXVIII. Male and Female.

      Wings long, with the first quill longest, and exceeding the first secondary by eleven-twelfths of an inch; middle toe and claw longer than the tarsus; tail of moderate length, nearly even, with acuminate feathers. Male olive-green above; a ring of yellowish-white round the eye; the head, neck all round, and part of the breast ash-grey, the sides greyish-green; the rest of the lower parts bright yellow. Female olive-green above, yellow beneath, the sides of the neck and a band across the breast tinged with brown.

      Male, 53/4, 8.

      New Jersey, Pennsylvania, and Connecticut. Very rare. Migratory.

      Connecticut Warbler, Sylvia agilis, Wils. Amer. Orn. v. v. p. 64.

      Sylvia agilis, Bonap. Syn. p. 84.

      Connecticut Warbler, Sylvia agilis, Nutt. Man. v. i. p. 399.

      This species forms a connecting link between Sylvicola and Trichas, having the long pointed wings of the former, and the general appearance of the latter, which it resembles, especially in its tail, which is neither emarginate, nor marked with the white spots seen on that of almost all the other Sylvicolæ, but which do not exist in the genus Trichas. Some of the Sylvicolæ are, in like manner, assimilated to Myiodoctes, and others to Vermivora. Of the former may be mentioned, Sylvicola Auduboni and S. coronata; of the latter, S. Blackburniæ.

      GENUS III. TRICHAS, Swains. GROUND-WARBLER.

      Bill of moderate length, similar in form to that of Sylvicola, differing only in being a little decurved. The general form does not differ materially from that of Sylvicola, the head being ovate and of moderate size, the neck short, the body rather slender; the feet of moderate length, slender; tarsus slender, much compressed, longer than the middle toe with its claw, anteriorly covered with eight scutella, of which the upper are blended; toes of moderate size, hind toe proportionally large, lateral toes equal, fourth adherent at the base; claws rather long, arched, much compressed, laterally grooved, very acute. Plumage soft and blended. Wings rather short, convex, considerably rounded, the third and fourth quills longest, the fifth little shorter. Tail of moderate length, rounded, always plain, or without white spots.

      100. 1. Trichas Macgillivrayi, Aud. Macgillivray's Ground-Warbler.—Macgillivray's Warbler.

      Plate CCCXCIX. Fig. 4. Male. Fig. 5. Female.

      Wings rather short, the second quill longest, the fourth longer than the first, the tail long, considerably rounded, its feathers rounded; tarsus longer than the middle toe and claw. Male olive-green above; the head, hind part, and sides of the neck bluish-grey; the fore neck and part of the breast greyish-black, lunulated with greyish-white; a black loral band; a conspicuous white spot on each eyelid; the lower parts bright yellow. Female olive-green above, yellow beneath, the sides of the neck and a band across the breast ash-grey.

      Male, 51/4, 61/2. Female, 5, wing 2/12.

      Columbia River. Common.

      Macgillivray's Warbler, Sylvia Macgillivrayi, Aud. Orn. Biog. v. v. p. 75.

      101. 2. Trichas Philadelphia, Wils. Mourning Ground-Warbler.—Mourning Warbler.

      Wings of moderate length, with the second quill longest, the fourth shorter than the first; the tail long, considerably rounded, its feathers scarcely pointed; tarsus longer than the middle toe and claw. Male olive-green above, the head, hind part and sides of the neck, bluish-grey; the fore neck and part of the breast deep black, lunulated with white; a blackish loral band, margins of eyelids dusky grey; the lower parts bright yellow. Female olive-green above, yellow beneath, the sides of the neck and a band across the breast ash-grey, the throat yellowish-white.

      Plate XXIII. Male and Female. Plate XXIV. Young Male.

      Wings rather short, with the third and fourth quills longest, fifth longer than second, first and sixth equal; tail considerably rounded, the lateral feathers being three-twelfths shorter than the middle. Male with a broad band of black across the forehead, including the loral space and eyes, and terminating in a rather pointed form behind the ear-coverts; over this band a narrow one of very pale blue, or bluish-white; upper parts yellowish-green, on the head slightly tinged with red; quills and tail-feathers wood-brown, margined with yellowish-green; the edge of the wing and the margin of the outer primary yellow; fore part of neck bright yellow, as is the anterior part of the breast and the lower tail-coverts, the rest pale, the sides shaded with dull yellowish-brown; the axillaries and some of the lower wing-coverts white.

      Wing rather long, much rounded, with the third and fourth quills longest, sixth longer than second, first and tenth about equal; tail much rounded, the lateral feathers being half an inch shorter than the middle. Male with a band of black across the forehead, including the loral space and eyes, and terminating on the ear-coverts; upper part of head light greyish-blue, tinged behind with green; the rest of the upper parts dull yellowish-green; quills and tail-feathers wood-brown on the inner webs, the edge of the wing and margin of the outer primary yellow; all the lower parts rich yellow, excepting the sides, which are shaded into dull greenish-yellow.
