Birdlife Australia's Aussie Bird Backyard Count is underway

You can use your spotting skills this week with Birdlife Australia's Aussie Bird Backyard Count.

Birdlife Southern Highlands liaison and conservation officer Christine Kelly said it was a "citizen-science initiative".

"The more you record, the better the data is," she said.

It requires participants to go out every day from October 18 to 24, and use the Aussie Bird Count app to document the birds they see.

Mrs Kelly advised people to go out to different spots every time they go out to make their observations.

"It is very important for Birdlife to have data on what's happening to common birds like currawongs, crested pigeons, minors and magpies," she explained.

The liaison and conservation officer said the database would be crucial after the 2019/20 bushfires.

"It paints a picture of recovery after the fires," she explained.

"The fires caused birds to move away for food and water, so we hope with the regeneration, that there are birds that come back."

She also explained that the app would help people identify different birds.

The Aussie Bird Count app can be found on the Apple app store and Google Play.
