Behaviour/Ecology: Population in Singapore originated from introduced escaped individuals around the mid 1930s. A massive range expansion of this species occured through the Peninsula in the past century while the locally introduced population was expanding massively. This self-introduced population eventually reached Singapore some time after the 1980s to merge with the local (introduced) population. The current population in Singapore hence has a mixture of introduced and self-introduced ancestry. This species has also been introduced to various places globally and is listed in "100 of the World's Worst Invasive Alien Species" by the IUCN.
Local Status: Uncommon resident
Conservation Status: Least Concern (BirdLife International 2017)
