Twitchers are tape-recording more kererū, pīwakawaka, and tūī in their yards each year, according to the garden bird study.
Manaaki Whenua landcare research study has actually been co-ordinating the mid-winter resident science job for 16 years.
It was now keeping in mind longer-term patterns, such as population development slowing down.
Tūī counts increased 266 percent in the last years however that slowed to simply a 25 percent boost over the last 5 years.

Over 10 years, kererū counts reveal a moderate 83 percent boost and a boost of 10 percent over 5 years.
There were 55 percent more pīwakawaka over ten years compared to the shallow boost seen recently.
Meanwhile, korimako (bellbird) numbers have actually fallen more than a quarter in a number of areas.
Survey co-ordinator Dr Angela Brandt informed Morning Report every individual invests an hour in their garden every day throughout the study and records the optimum variety of each types they hear or see.
Since 2012, bird counts have actually been collected from almost 44,000 garden studies.
Nothing was triggering specific alarm this year, Brandt said.
In a couple of areas there were shallow to moderate decreases in the short-term for tauhou (silvereyes), korimako in the North Island and some presented types, she said.
“It’s something to watch on however we understand individuals are doing great deals of work to enhance things for birds with predator-free efforts and repair efforts.”
Participants advised handling weeds and predators, making certain bird food wasn’t available to predators and developing routines for birds to feed and nest.
This year’s study ranges from 24 June to 2 July.
