What benefit did the invasive species called Japanese white eye bring to the ie ie vine?

Pollination of plants

Explanation:

This species of birds is thought to help in preserving and conserving the native plant species of Hawaii by helping in dispersing their seeds. They are the main pollinators of the ieie vine. These was a role that was once performed by the long extinct Hawaii native bird species (they became extinct due to the invasion of these Japanese white eye).
