[83] Length 12¹⁄₂ inches, expanse 15¹⁄₂, flexure 5, tail 6³⁄₄, rictus 1⁴⁄₁₀. tarsus 1¹⁄₁₀, middle toe 1¹⁄₁₀, versatile toe ⁹⁄₁₀. Intestine 10 inches; two cæca, 1¹⁄₄ inch long, about 1¹⁄₂ inch from cloaca. The tawny underparts, contrasted with the sober grey of the upper, glossed like shot-silk, and the long tail beautifully barred with black and white, render the subject before us one of the handsomest of this genus of Cuckoos. It is a dull, and, so to speak, a stupid bird; we not unfrequently see it suddenly fly out from the woods, and crossing the road rest on a branch at a short distance, where it sits little disturbed by the proximity of passengers: or jumps to another twig near, and thence to another. I have never heard it utter a sound. It lives on soft insects, large spiders, &c., which are stationary, and which it seeks by thus peeping among the trees, and for the capture of which long flights would be unnecessary. I know nothing of its domestic economy; but in January I have found eggs in the ovary, as large as dust-shot. The shortness of the intestinal canal, and its freedom from convolutions is remarkable, and struck me forcibly by comparison with that of a White-winged Dove, which I happened to dissect on the same day with this. The length of the intestine in the granivorous bird was forty-one inches, that in the insectivorous, ten. SAVANNA BLACKBIRD.[84] _Crotophaga Ani._—+Linn.+ Pl. Enl. 102. [84] Length 14³⁄₄ inches, expanse 17³⁄₄, flexure 6¹⁄₄, tail 7³⁄₄, rictus 1³⁄₁₀, height of beak ⁹⁄₁₀, tarsus 1⁸⁄₁₀, middle toe 1⁹⁄₁₀. Irides deep hazel, feet black; beak black, the ridge semitransparent, furrowed perpendicularly. Plumage black, with rich purple reflections, most conspicuous on the wing-quills; the clothing feathers have the disk of an intense black, with a lighter border, brilliantly iridescent; the borders on the neck are larger in proportion, and are sometimes brassy. Intestine 12 inches; two cæca, 1¹⁄₂ inch long, 2 inches from the cloaca. The young have not the scaly character of the plumage, nor any ridge upon the beak.
