The Red-throated Diver frequents the shores of Hudson’s Bay up to the extremity
of Melville Peninsula, and is also abundant on the interior lakes. It lays
two eggs, on a little down, by the margin of the water: those brought home by
Sir Edward Parry are 35 lines long, 21 wide, and have a pale oil-green colour.
DESCRIPTION
Of a specimen, killed at Hudson’s Bay, lat. 57°.
Colour.—Head, chin, and sides of the neck, lead-coloured ; centres of the plumage on
the top of the head hlackish. Front of the neck occupied by a stripe that widens downwards,
of rich cochineal or purplish-red. Hind head, back of the neck, shoulders, and sides of the
breast, greenish-black, striped on the margins with white. Dorsal plumage and wings pitch-
black ; narrow space under the wings and under tail coverts also black, with whitish borders.
Under plumage and inner wing coverts white, the axillaries striped on the shafts with
blackish-brown. Bill black. Legs blackish-green.
Younger individuals have the dorsal plumage interspersed with minute marginal spots, a
pair near the tip of each feather.
Form.—Bill having the commissure quite straight; but, the upper mandible being considerably
depressed at the front, the ascending gonys of the lower one causes the bill, when
closed, to appear very slightly recurved; margins of both mandibles greatly incurved. Tail
of twenty feathers. Hind toe having a smaller lobe, and connected with the inner one by
a larger web than in C. gladdlw. The nails more slender.
