Justification for EICAT assessment


It is possible that competition with Red‐breasted Parakeets is causing the decline of the Long-tailed Parakeet (Psittacula longicauda), with loss of suitable nest holes. The abundance of Long‐tailed Parakeet has dropped, while Red‐breasted Parakeet abundance has increased in parrot counts (Yong and Owyong 2012).
Confidence rating

Countries of most severe impact
Republic of Singapore
Description of impacts
The Red-breasted Parakeet feeds on native plant species and it is possible that competition with Red‐breasted Parakeets is resulting in a decline of native Long-tailed Parakeets in Singapore.
