This bird is represented by Du Pratz as held in high estimation by the aborigines of Louisiana, who used its feathers for ornamenting the calumet or symbol of peace. It may have been an albino of a known species, or distinct and now unknown. The description applies to a beautiful Mexican species, _Buteo Ghiesbrectii_ (Dubus), which is about the size of the Red-tailed Hawk (_B. borealis_), and should it ever be observed in Louisiana, the question may be considered as settled. 3. Falco variegatus. Gm., Syst. Nat., I. p. 267. (1788.) The Speckled Buzzard. Lath., Syn., I. p. 97. “Length more than 12 inches; in shape like our common buzzard. The bill is dusky; the whole head and neck as far as the shoulders whitish; the shaft of each feather blotched irregularly with rusty-brown; back and wing-coverts brown, several of the feathers, especially on the wing-coverts, are spotted with white; tail dark brown, crossed with several bars; but these are nearly obsolete, appearing on close inspection; the quills are very dark, almost black; the under parts from the breast are white; down the shaft of each feather is a blotch of brown; these marks spread out larger and broader as they proceed downwards to the belly; thighs pretty much the same; vent plain white; legs yellow; claws black. A fine specimen of this bird is in the Leverian Museum, which came from North America.” (Latham, as above.) Generally cited as a synonyme for the Marsh Hawk, _Circus hudsonius_, with, as we think, but a small degree of propriety. It appears to us to be the young of either _Buteo pennsylvanicus_ or _Accipiter cooperii_, or an unknown bird. 4. Falco albidus. Gm., Syst. Nat., I. p. 267. (1788.) The Buzzardet. Penn., Arct. Zool., I. p. 245. “With dusky bill; head, cheeks, neck, breast and belly white, marked with large brown spots more sparingly dispersed over the breast and belly; lesser coverts brown; the others colored like the head; primaries dusky; thighs white, with small sagittal spots of brown; tail dusky, barred and tipped with white; legs yellow. Length, 15 inches. It has much the habit of the Buzzard, but the legs in proportion are rather longer. In the Leverian Museum. Except in the almost uniform color of the tail, Mr. Latham’s species, p. 97, No. 83, agrees with this (which is the preceding _F. variegatus_). North America.” (Pennant, as above.) Probably the same as the preceding. 5. Falco obsoletus. Gm., Syst. Nat., I. p. 268. (1788.) The plain Falcon. Penn., Arct. Zool., I. p. 242.
