Note 65 — Family FALCONIDÆ.—The Falcons. (continued 2)

Falco sparverius, var. dominicensis. Accipiter (Æsalon) dominicensis, Brisson, Orn. I, 389, pl. xxxii. f. 2, 1760. Falco dominicensis, Gmelin, Syst. Nat. p. 285, 1789. Tinnunculus dominicensis, Strickl. Orn. Syn. I, 100, 1855 (in part only). Tinnunculus sparverius, var. dominicensis, Ridgway, Pr. Ac. Nat. Sc. Philad. Dec. 1870, 149.

Hab. Lesser Antilles north to Porto Rico and St. Thomas.

Adult ♂ (52,428, St. Bartholemi; Professor Sundevall). Resembling var. isabellinus in general appearance, but darker, and more heavily barred above; beneath much more spotted. Head above with blackish shaft-streaks and vertex with a patch of rufous; this, however, somewhat restricted. Rufous above, with numerous broad bars of black, these running continuously across and extending anteriorly to the neck; rump even, with a few very small, transversely sagittate specks of the same. Tail crossed by nine perfectly regular and sharply defined narrow bands of pure black, anterior to the subterminal zone, which is about .80 of an inch wide; outer feather white, tinged medially with rufous, barred with black to the base. Black spotting in dark cinereous of the wing very exaggerated in comparison with var. sparverius. Markings beneath very numerous, the sides being thickly marked with large cordate or nearly circular spots of black, these growing larger toward the flanks. The rufous of the breast is about as in var. isabellinus. Wing, 6.80; tail, 5.10; tarsus, 1.40; middle toe, .94; culmen, .53. Wing-formula, 3–2–4, 5, 6–1.

♀ (52,429, St. Bartholemi; Professor Sundevall). Black bands above exceeding in breadth the rufous ones; each feather of the head above with a sharp medial streak of black. Tail with twelve bands of black; outer feather approaching white. Markings beneath pure black, as in the male; their course longitudinal anteriorly, on the sides more circular, transverse on the flanks. Wing, 6.70; tail, 5.00; tarsus, 1.30; middle toe, 1.00; culmen, .53. Wing-formula, 3, 2–4–1, 5.

The male selected for the type is an extreme example; no others have the character of the variety presented in a degree as exaggerated as this specimen. Nos. 362 (♂) and 170 (♀) of the Bryant Collectionisabellinus style; but the spots are larger and more numerous even than in any examples of sparverius. A female from here differs from the type only in a few unimportant points, the principal difference being in the markings beneath. In this there is a general ochraceous wash on the lower parts, the markings linear only on the breast, becoming tear-shaped and circular on the sides, and transverse on the flanks; the red patch on the crown is quite extensive. In the whole series the third quill is longest, and the bill is, in all, considerably longer than in any specimen of sparverius excepting those from Florida. Another female from St. Thomas (36,551; Robert Swift) is almost exactly like the one from Porto Rico; the rufous of the crown covers nearly the whole top of the head, and is quite bright. In a series of skins belonging to Mr. Newton, deposited in the S. I. Collection, we find a pair of this variety from the island of St. Croix, W. I. They are perfectly typical examples. The male (“May 2, 1857, B. B.”) has the large black spots of the side transversely cordate; the bands on the tail are broken into spots on edges of the feathers; the female (“s. p. 227, B. 6”) is in nearly all respects like the specimen described.
