Tūī are important pollinators and seed dispersers within our ecosystem. Due to the effects of predation and a limited food source, few tūī were sighted within Hamilton City in the early 2000's.
The Hamilton Halo project is designed around a two-pronged approach to attract tūī back into Hamilton City.
Firstly, the project aims to increase tūī populations in the vicinity of the city by boosting breeding success at several key breeding sites within a 20 kilometre radius of Hamilton City, creating a halo of tūī. These sites are labelled on a Waikato Regional Council map.
Increasing predator control methods at these sites allows greater fledgling rates to occur. Waikato Regional Council also works alongside Hamilton City Council and landowners to reduce the effects of predation on tūī.
Increasing the planting of key species within Hamilton City to produce food sources for tūī is the second aim of the project. By planting a wide variety of species, tūī will have flowers and nectar to feed on throughout the year.
While the project is focused primarily on tūī, Waikato Regional Council hopes other native birds such as bellbirds and kererū will also be encouraged to inhabit the city.
An ongoing success
From 2004–2019, tūī numbers increased 25-fold in Hamilton City. Tūī are the third most common native bird in the city's green areas – after the fan tail and grey warbler. Bellbird (korimako) and kererū are also being sighted. There is evidence the New Zealand falcon (kārearea) and kaka may also become more regular visitors to Hamilton.
