小葵花风头鹦鹉原产于澳大利亚，由宠物交易进入新加坡，笼养鸟逃逸后在野外繁殖建立了种群，所以今天我们在本地看到的这种鹦鹉是“外来种”。在国大校园中栖息着一个种群。
The Yellow-crested cockatoos (Cacatua sulphurea) originated in Australia. They were brought into Singapore by pet trade and subsequently released or escaped. They have established themselves in Singapore and have feral breeding populations。There is a population living in NUS campus.

Might not be sulphur-crested cockatoo, but yellow-crested cockatoo (Cacatua sulphurea) instead, from Indonesia. This species is known to be breeding in Singapore, while the sulphur-crested has not been confirmed to be breeding here yet.

Thanks for the correction.
