Northern Beaches bird lovers are being asked to participate in the annual Aussie Backyard Bird Count, which starts today.

The count is organised by BirdLife Australia, a not-for-profit founded in 1901, which is dedicated to the conservation of Australian birds and their habitats through advocacy, field work and targeted research.

Last year, the survey which relies on everyday Australians volunteering to count birds in their favourite outdoor space, saw 3.4m birds counted over the week.

To start counting, register at Aussie Backyard Bird Count. Download the app on your smartphone or tablet and follow the field guide. Alternatively, submit sightings online.

Participants need to commit 20 minutes per day in a favourite outdoor space and may complete as many 20-minute counts as desired until Sunday, 25 October.

BirdLife Australia says everyone can take part and it is the perfect activity to unwind from anxieties and stresses.

There is an opportunity to win prizes, national totals will update in real time, and the app will allow participants to see species spotted in their local area.

BirdLife Australia says the data will help to protect almost 900 bird species and their habitats in Australia.
