It will soon be added to population figures as part of the Great Kereru Count which starts today.
A Great Kereru Count spokesman said the project was focused on learning more about kereru numbers around New Zealand.
People could make a record of any kereru they spotted throughout the week and submit their reports online or through an app.
Last year, Dunedin had the second-highest level of participation in New Zealand, with 1080 observations made and 2613 kereru counted.
This year was the eighth and final year of the count.
The information gathered would help researchers understand where kereru lived, their numbers and how best to protect them, the spokesman said.
The count will run from September 17 to 26.
