Amazona lilacina is listed as endangered in its home range of Ecuador - estimated less than 2500 in the wild. Even feral populations outside the natural range can have considerable importance in these sort of circumstances. This applies with other species as well incidentally - Java Sparrow Lonchura oryzivora is listed as Vulnerable in its native range and is probably worse, but has numerous introduced populations around the world as a result of the cage bird trade. Similarly, in the UK Mandarin Duck and Chinese Water Deer are of conservation significance, despite being introduced species
