NZ Garden Bird Survey 2021 results now out!
You came, you saw and you counted. And now we can share the results of your hard work. When you headed into the gardens, schools and parks around New Zealand in July last year to count the garden birds, it was as part of the country’s longest running citizen science project – the New Zealand Garden Bird Survey. Our researchers have crunched the numbers – not an easy job with over 42,000 completed surveys since 2010 – and have tweeted the 2021 findings. Read the report: The State of NZ Garden Birds | Te āhua o ngā manu o te kāri i Aotearoa 2021 According to the State of NZ Garden Birds | Te āhua o ngā manu o te kāri i Aotearoa 2021 our researchers found: Data analysis showed positive signals emerging for four native species: Kererū counts show a 102% increase over 10 years. Pīwakawaka (fantail) counts were up 47% over the same timeframe. Tūī (kōkō) continue to increase nationally (30% over 10 years), and increasingly in Canterbury, Marlborough, Otago, and the West Coast. Silvereye (tauhou) showed a moderate increase in numbers since 2016, which means their slow decline is lessening. Things are not looking so good for starlings. Numbers continue to decline over both the five and 10 year period, although their rate of decline has slowed compared to last year. Numbers of song thrush, house sparrows, dunnock, chaffinch, and korimako (bellbirds) show little change over the past five years. There has been little change to myna counts nationally, except in Wellington where they have shown a rapid increase – 202% over the past 10 years. Manaaki Whenua researcher, Dr Angela Brandt, says the data collected over the week in July last year lets us understand how bird populations are changing across New Zealand. “What’s exciting about having so many years of surveys now is that we can see how trends are changing over time. Some species show an uptick – like kererū – or a lessening decline – like tauhou – compared with earlier reports.
“Importantly, because the survey is done every year, we could have an early warning if a species started to decline.”
The 2022 survey – not far away! This year the survey runs from 25 June – 3 July 2022, so there’s plenty of time to start learning to identify the birds that visit your garden. Saturday, 25 June – Sunday, 3 July Have you saved the date? How to take part Here’s a quick reminder of how easy it is to get involved: Visit the NZ Garden Bird Survey website to get started and download a tally sheet. Select a garden, marae, local park or school grounds. Choose any ONE day between 25 June and 3 July, 2022. Look and listen for birds on that day for ONE hour. For each species, record the HIGHEST number seen or heard at one time. Submit the results online at the NZ Garden Bird Survey website – a link to the survey form will go live on the home page from the 25 June. Resources Head over to the New Zealand Garden Bird Survey website and you’ll find all sorts of tools and resources. Use these guides to help you identify birds commonly seen around Aotearoa’s gardens, schools and parks. You can recognise birds by their colour, shape, size, sound and flight pattern.

Do you know your starling from your blackbird? What did you hear?
If you heard a strange grunting sound from the trees, would you think it’s a lost boar or a kākāpō? (spoiler alert: kākāpō and pigs sound strangely similar). Resources in te reo Māori
Added for all our kura, kaiako, tamariki and whānau taking part! And lastly… From all of us in the New Zealand Garden Bird Survey team, thank you once again for your warm and enthusiastic participation in this, the longest running citizen science project in New Zealand – we couldn’t have done it without you.
