Includes Enggano White-eye
- Zosterops simplex
Identification
Mostly olive-green above and medium grey below with yellow throat and vent areas. In the head has a white eye-ring that is broken in front, width above eye is about half of eye diameter. There is a black loral line continuing below the eye-ring and yellowish above lore and at the front of the head. Bare parts are grey and brownish iris.
Distribution
China, Taiwan, Indochina, Thailand, Malaysia, and western Indonesia.
Taxonomy
Five subspecies are recognized:
- Z. s. simplex
- Breeds in eastern China (from extreme southern Gansu east to Jiangsu, south to eastern Yunnan, Guangxi, Guangdong and Fujian), Taiwan, and northeastern Vietnam; northern populations migratory, wintering from southeastern China to Thailand and central Indochina
- Z. s. hainanus
- Hainan (s China)
- Z. s. williamsoni
- Southern Thailand and east coast of northern and central Thai-Malay Peninsula
- Z. s. erwini
- Coastal forests of the western and southeastern Thai-Malay Peninsula, of Sumatra, the Riau Islands, Bangka, and the Natuna Islands; population of coastal western Borneo provisionally assigned here, but possibly a distinct taxon
- Z. s. salvadorii
- Enggano and Mega islands (off w Sumatra)
The last subspecies used to be considered a full species, Enggano White-eye. Subspecies williamsoni used to be part of the now former Oriental White-eye. The remaining subspecies seems to have come from the former Japanese White-eye.
Habitat
Mostly a bird of lowlands and especially in the southern end often found in or near coastal areas. Mostly found in forest, woodland, rubber plantations, gardens, and mangrove but in Enggano often in Coconut plantations.
Behaviour
Especially northern populations are migratory.
Feeding
Food includes fruit, buds, seeds and nectar, but also insects are taken. Frequently moves around in mixed species flocks where hovering to find food is employed.
