Australian magpies were introduced to New Zealand in the 1860s but have a long-standing connection to Aotearoa than previously thought.

The St Bathans currawong lived in New Zealand about 19 to 16 million years ago during the Early Miocene .

New Zealand's Miocene flora included many fruit-bearing trees and offered abundant food.

Currawongs eat a wide variety of fruits, insects and small animals.

But a cooling climate limited their habitat near the end of the Miocene , about five million .

Understanding this deep history allows us to view concepts such as "native" and "introduced" with more nuance.

We then appreciate that the biodiversity we have today is but one snapshot in a long, dynamic and ever-unfolding story.

Change is to be expected and ongoing, as seen in the newest of New Zealand's native birds, the barn owl and Australian wood duck.
