Successful 'alien' bird invasions are location dependent

Published today in Nature, researchers show that alien bird introductions are most successful in locations and climates similar to their native habitats and in places where other alien species are already established.

Indigenous (ecology)

In biogeography, a species is defined as indigenous or native to a given region or ecosystem if its presence in that region is the result of only natural resources, with no human intervention. Every natural organism (as opposed to a domesticated organism) has its own natural range of distribution in which it is regarded as native. Outside this native range, a species may be introduced by human activity; it is then referred to as an introduced species within the regions where it was anthropogenically introduced.

An indigenous species is not necessarily endemic. In biology and ecology, endemic means exclusively native to the biota of a specific place. An indigenous species may occur in more than one locale.

The terms endemic and indigenous do not imply that an organism necessarily originated or evolved where it is found.
