The Oriental
White-eye (Zosterops palpebrosus) is a small passerine bird in the white-eye
family. It is a resident breeder in open woodland in tropical Asia, east from
the Indian Subcontinent to Southeast Asia, extending to Indonesia and Malaysia.
They forage in small groups, feeding on nectar and small insects. They are
easily identified by the distinctive white eye-ring and overall yellowish
upperparts. Several populations of this widespread species are named subspecies
and some have distinctive variations in the extent and shades of yellows in
their plumage.
This bird is
small (about 8–9 cm long) with yellowish olive upper parts, a white eye ring,
yellow throat and vent. The belly is whitish grey but may have yellow in some
subspecies. The sexes look similar. The species is widespread and is part of a
superspecies complex that includes Zosterops japonicus, Zosterops meyeni and
possibly others. The taxonomy of the group is still unclear with some island
populations being distinctive while some subspecies are not well supported. The
population from Flores, Indonesia for instance is found closer to the Pale
White-eye. The family itself is now questioned since they are nested along with
the Stachyris babblers.
About eleven
subspecies are well recognised. These include the nominate form (type locality
Bengal, India) which is found from Oman and Arabia, Afghanistan, northern India
and extends into China and northern Myanmar. The population in the Western
Ghats and hills of southern India is placed in nilgiriensis while salimalii of
the Eastern Ghats hills (Shevaroy, Chitteri, Seshachalam, Nallamalai) is
sometimes subsumed into the nominate race. The population of the plains of
India, Laccadives and Sri Lanka are sometimes placed in egregius (= egregia)
but is restricted by other works to the population in Sri Lanka.The populations
in southern Myanmar, Thailand and Laos are placed in siamensis. The Nicobar
Islands form is nicobaricus and is sometimes also used for the population on
the Andaman Islands which are however distinctive and a distinct unnamed
population.The populations from southern Thailand to western Cambodia are
placed in williamsoni.Other Southeast Asian island forms include auriventer
(=aureiventer), buxtoni, melanurus and unicus.Race occidentis (now often
subsumed into the nominate race) of the Western Himalayas has the upper side
dark green and the flanks are tinged in brown. The form salimalii has a shorter
bill and is brighter yellow-green above. Some authors consider the nominate
race to be restricted to Sikkim, Bhutan, Assam and Yunnan and consider the
peninsular race as occidentis (or
amabilis if the form from Kathiawar described by Koelzis considered valid).
In Sri Lanka,
race egregia is smaller and has a brighter back and throat than the endemic Sri
Lanka White-eye, Zosterops ceylonensis found in the central hills.
The English
and scientific names refer to the conspicuous ring of white feathers round the
eyes, zosteropsbeing Greek for 'girdle-eye'.
