OMNIVOROUS BIRDS. 
The male is 12 inches long, and 18 in alar extent. The prevailing 
black color of the body is relieved by glossy reflections of steel blue, 
dark violet and green ; the violet is most conspicuous on the head 
and breast, and the green on the hind part of the neck. The back, 
rump, and whole lower parts, with the exception of the breast, reflect 
a cupreous gloss. The wing-coverts, secondaries, and coverts of 
the tail, are light violet, with much of the red ; the rest of the wings 
and rounded tail are black, with a steel-blue gloss. Iris silvery. — 
The female is rather less, but very similar in color, and glossy parti- 
colored reflections. 
BLACK ORIOLE, or SLENDER-BILLED BLACK- 
BIRD. 
( Quiscalus baritus, Bonap. Gracula barita, Lin. Oriolus niger> Gm» 
Latham, i. p. 185. Black Oriole, Pennant. Buf. pi. enlum. 534.) 
Sp. Charact. — Glossy black, with uniform bluish reflections faint-

edged with ferruginous ; tail nearly even, extending beyond the 
wings more than 2 inches ; osseous carina small ; length 10J 
inches ; vertical breadth of the bill at base about J of an inch. — - 
The female scarcely smaller, dull brownish; beneath and eye- 
brows whitish. 
Of this species I know little more than that it is occa- 
sionally seen in this vicinity in the spring, and has habits 
very similar to the Ferruginous Blackbird. It is, how- 
ever, distinguished at once, both from this and the com- 
mon species, by its more slender elongated form, al- 
most unvaried color, and general look even of a Thrush. 
According to Pennant, they migrate as far north as Hud- 
son’s Bay, arriving there about the beginning of June, 
and feed on insects and their larvse, singing agreeably 
till the time of incubation, but afterwards only utter a 
chucking noise till the young take to flight, when they 
resume their song. They build their nests in trees, about
