The mustached parakeet has an extensive range in southeast Asia. It is native to China and the islands of Indonesia, where several subspecies live. This bird has an unmistakably deafening warning calling when danger approaches. During the mating season, a pair will leave the flock and find a tree cavity to call home until their chicks mature. Feral populations are spreading to many other areas, including neighboring cities. Their shrinking natural habitat causes flocks to become urban dwellers. In the wild, this species tends to live in woodlands, hills, and mountains and gather in flocks of up to 60 birds. The group can become quite loud, so it’s hard to miss them.
