Here’s the formal list of the new species, with subspecies and ranges; the subspecies with an asterisk have undergone a name change because of reorganization under a different species; all the below species are reconstituted, but the ones that have a change to the English name associated with the scientific name have two asterisks

YOUR LIFE LIST’s EXECUTIVE SUMMARY

In one more attempt to help this all make sense, or for those who don’t like cooking, below is a chart of how your records may have changed by country:


  • If you had reported Japanese White-eye (Z. japonicus) from Russia, Japan, South Korea, Taiwan, Indonesia, or Hawaii, USA, those records will now show as Warbling White-eye Zosterops japonicus
  • If you had reported Japanese White-eye (Z. japonicus) from China, Hong Kong, Taiwan, Vietnam, Laos, Cambodia, Myanmar, or Thailand, or introduced populations from California, USA* or Singapore, those records will now show as Swinhoe’s White-eye Zosterops simplex [* note – California records from San Diego County from prior to 2006 pertain to Indian White-eye Z. palpebrosus).
  • If you had reported Mountain White-eye (Z. montanus) from anywhere, it will now show as Warbling White-eye (Zosterops japonicus)
  • If you had reported Oriental White-eye (Z. palpebrosus) from anywhere west of Thailand (e.g., India, Bhutan, Nepal, Pakistan, Myanmar, Bangladesh etc.) those will now appear as Indian White-eye Zosterops palpebrosus.
  • If you had seen Oriental White-eyes (Z. palpebrosus) in mangrove or coastal habitat in s. Thailand, s. Myanmar, Malaysia, Singapore, Sumatra, or on Borneo, those will now appear as Swinhoe’s White-eyes Zosterops simplex. Note that these birds have a yellow ventral stripe, while inland, migratory Swinhoe’s do not.
  • If you had Oriental White-eye from Java, Sumatra (inland areas, not coastal ones), or Bali, then those are now Sangkar White-eye Zosterops melanurus melanurus
  • If you had reported Everett’s White-eye (Z. everetti) from either of two popular parks in Thailand–Khao Yai NP or Kaeng Krachan NP–these will now appear as Hume’s White-eye Zosterops auriventer, as will any others from peninsular Thailand, Malaysia, Singapore, or Borneo. Please note also that many observers also seem to have reported Oriental White-eye Z. palpebrosus from those areas; it was only recently discovered (in 2004, see the paper here) that subspecies wetmorei was the predominant white-eye in Khao Yai (other than Chestnut-flanked) and no other similar species have been found in either area before or since. Because of this, we have converted all reports of Oriental White-eye to Hume’s White-eye from those areas as well.
  • If you had any of the following:
    • Any Oriental White-eyes from Sumbawa and Flores in the Lesser Sundas, this would be subspecies unicus, which is now moved to Ashy-bellied White-eye Zosterops citrinella
    • Any sightings of Enggano White-eye (Z. salvadorii) then these are now Swinhoe’s White-eye Zosterops simplex.
    • Mountain White-eye from Marinduque (Phillippines), then these are subspecies gilli which is now Lowland White-eye Zosterops meyeni
