Plate CCLVII. Male.
Tail of twelve feathers. In summer an elongated tuft of about forty
long, slender, loose, recurved feathers, from behind the eye to the
length of an inch and a half on each side; upper mandible dusky, along
the edges greenish-yellow, lower yellow, irregularly marked with
dusky toward the edges; bare space on the head, and gular sac rich
orange; plumage greenish-black, strongly glossed with green;
imbricated feathers on the back and wings greyish-brown, their
fringe-like margins greenish-black; primary quills brownish-black,
secondary like the other wing-feathers; tail black; the shafts of all
the feathers black. Female similar to the male. After the breeding
season the tufts disappear. Young after the first moult have the head
and neck mottled with greenish-black and greyish-brown, the other
parts as in the adult, but the tufts on the head wanting.
