REMARKS.--The Black-headed Oriole has been recorded from Palawan and
Calamianes Islands only in the Philippines. The Palawan representative
form is strongly marked and easily to be distinguished from _O. x.
xanthonotus_ of Java.
The bird of Borneo may represent still another form, distinguished
from true _xanthonotus_ by slightly smaller size, the under parts less
purely white, that is, much more suffused with yellowish or yellowish
ochraceous, sometimes even with grayish and with the yellow tail-spots
larger. This form probably should be known as _Oriolus xanthonotus
consobrinus_ Wardlaw-Ramsay (P. Z. S., 1879, p. 709, N. E. Borneo).
Everett, however, (Birds of Borneo 1889, p. 119), in mentioning the
type states that "It is dissimilar from all known immature individuals
of _O. xanthonotus_ and belongs rather to the _O. steerii_ group." If
this is true and there is in north Borneo a form of the Philippine
group of Orioles, with the sexes alike in plumage and with the throat
and chest plain gray, then the form of the Black-headed Oriole of
Borneo, if recognized, should be named.
In old females from Java the pileum and cheeks are dark mouse-gray,
blackish on the forehead, the black streaks narrow, almost obsolete
and noticeable on the crown and occiput only. Females from the
mainland and Borneo and Sumatra also, when adult, have faint blackish
streaks on the crown. In immature plumage the head is wholly
unstreaked, which I doubt to be the case in the Palawan form.
