| Mintage | Use | Feed Method |
|---|---|---|
| Tui | Major Pollinator | Hang upside down, lap nectar |
| Bellbird | Nectar Consumer | Hop between branches, probe efflorescence |
| Kingfisher | Insect/Pollen Mix | Hovering, aerial sallies for worm and ambrosia |
| Silvereye | General Feeder | Beak at bud and flush |
Why the Yellow Color?
