Zosterops auriventer

Identification

9.5-12 cm
Upperside olive-green, underside mostly medium grey but with bright yellow on throat, vent and in a central stripe going forward from the vent. Side of head shows black from eye to bill as well as a white eye-ring that is broken in front and above the eye is 1/3 as wide as the diameter of the eye.

Similar species

Swinhoe's White-eye has a wider eye-ring (1/2 of diameter above the eye), brighter supraloral area (yellowish rather than green) and a longer, more pointed bill. Swinhoe's also has brighter wing coverts.

Distribution

From southeastern Myanmar through the peninsula of Thailand and Malaysia to Borneo

Taxonomy

Four subspecies are recognized[1]:

  • Z. a. auriventer
    • Poorly known; documented only from southeastern Myanmar
  • Z. a. wetmorei
    • Southern Thailand and the northern Thai-Malay Peninsula
  • Z. a. tahanensis
    • Southern Thai-Malay Peninsula
  • Z. a. medius
    • Borneo

This species was defined only recently[2]. The subspecies included came from the former Oriental White-eye and Everett's White-eye.

Habitat

Mostly foothill areas down almost to sea level. Likes broad-leaved forest both primary and secondary, but also found in edges, plantations, and shrub nearby.

Behaviour

Main food seems to be native fruits, supplemented by nectar and small invertebrates.

Vocalisation

Song quality described as twittering.
