Oriental White Eye
The native population of the Oriental White-eye died out long before the 1970s - that is just a starting date for modern records. The current population is believed to have started from escape birds (popular cage bird), both accidentally or deliberately freed. They have been around for at least 20 years and the numbers have been increasing without a confirmed observation of the actual nesting. However, the status of this species was accepted in the late 1990s to early 2000s as CI or common introduction, not a mere escapee!
It is a common introduction like Javan Myna (Acridotheres javanicus), House Crow (Corvus splendens), Red-breasted Parakeet (Psittacula alexandri) and White-crested Laughingthrushe (Garrulax leucolophus). They all originated from escapees/releases and will never become Residents (R) which is reserved for true native inhabitants of Singapore and natural colonists from elsewhere who have established themselves here, like the Oriental Pied Hornbills (Anthracoceros albirostris) on Pulau Ubin for example.
