Hundreds of Bay of Plenty ducks are helping scientific research into their populations and habits by getting "blinged up" with bright, shiny bands on their legs.
As part of its annual research programme, Fish & Game puts the small metal bands on the ducks' legs to help gather crucial data such as the birds' movements, productivity, population sizes and survival rates.
Each band has a unique number which is recorded in the national bird banding database administered by the Department of Conservation.
When a band is recovered the number will show where and when it was originally banded and how long it has lived and travelled.
