Luzon (Whitehead).
"Adult male.--General color deep black with a slight purplish gloss,
especially on the back and breast; the middle of lower breast and belly
white, the under tail-coverts being edged with the same color. Wattle
surrounding the eye, bill, and feet said to be pale blue. Length,
216; wing, 89; tail, 114; tarsus, 15. The only specimen sent home by
Whitehead was not of his own collecting, but purchased in Manila and,
as I understand, said to have been obtained in that vicinity. The
color of the soft parts and sex are, I fancy, only given on the
authority of the collector from whom the bird was obtained." (Grant.)
Genus TERPSIPHONE Gloger, 1827.
Bill large and depressed; rictal bristles numerous, coarse, and long;
head with a full occipital crest; eye surrounded by a wide fleshy
wattle; rectrices graduated. The sexes are similar in plumage during
the first two years and the birds breed in this immature condition. In
the third year the male develops a distinctive plumage and his central
rectrices grow to twice the length of the second pair.
