Zosterops halconensis Mearns, Phil. Jour. Sci. (1907), 2,
sec. A, 360.
Mindoro (Mearns).
"Characters.--Sexes alike. Similar to Zosterops vulcani, but slightly
larger. Wing, 56 against 55 millimeters; tail, 42 to 41; culmen,
12 to 11.5. Color yellower, but without a longitudinal yellow stripe
on middle of abdomen; sides more whitish gray; cheeks and ear-coverts
paler and yellower, but the yellow confined to the chin and throat not
suffusing the upper chest; upper surfaces of a more golden green. From
Zosterops whiteheadi the Mindoro form is easily distinguished, when
similar seasonal plumages are compared, by its greater size and more
yellow coloration." (Mearns.)
