Dicæum sibutuense Sharpe, Bull. Brit. Orn. Club (1893), 3, no. 12,
10; Ibis (1894), 251, pl. 7, figs. 1 and 2; McGregor and Worcester,
Hand-List (1906), 97.
Sibutu (Everett).
"This is an interesting species, new to science. Like D. trigonostigma,
it has a slate-colored throat, but the latter is blackish slate-color,
like the sides of the face and head, and not lighter gray as in
D. trigonostigma. The Sibutu bird, moreover, resembles D. dorsale
in having an orange patch in the center of the back, the lower
back and rump being slaty gray, slightly washed with olive, and
not orange-yellow as in D. trigonostigma. The female, as might be
expected, closely resembles that of D. trigonostigma, but is tinted
with olive-green on the rump, and has not the orange shade of the
hen of the last-named species." (Sharpe.) [86]
The figure of the female of D. sibutuense in The Ibis has a pale
yellow patch on the back, a character which is found in no other
Philippine species of the genus.
