Orange River White-eye
Zosterops pallidus
The sexes are alike and measure 10–13 cm from bill to tail tip. It has pale olive green upper part plumage, a yellow throat and supraloral stripe, and a tawny buff tone to the flanks and sides of breast, which is regionally diagnostic. The lore plumage and bare parts are black. The juvenile plumage is a pale version of the adult's, and the white eye-rings appear during the second month.

Warbling White-eye
Zosterops japonicus
The warbling white-eye is olive green on its back, from anterior to posterior, and is pale green on its underside. Its feet, legs, and bill range from black to brown. It has a green forehead and a yellow throat. The white-eye has rounded wings and a long, slender bill – both of which indicate this bird to be very acrobatic. Its wings are dark brown but outlined in green. Like other white-eyes, this species exhibits the distinctive white eyering that gives it its name (mejiro, as the bird is known in Japan, translates to "white eye"). Adults range from 4 to 4.
