Copsychus malabaricus (White-rumped Shama)
Copsychus malabaricus is a passerine bird native to south and south-east Asia. Its popularity as a cage bird has caused significant population declines in parts of its native range, but international trade has resulted in the establishment (since the 1980s) of a feral population in Taiwan, where it is of concern as a possible invasive species. It was introduced in the 1930s to Hawaii, where there is concern that the well-established population may negatively affect native bird species. However there is no evidence confirming any significant negative effects in either Taiwan or Hawaii.
