This week on Earth Chat our guest is Sean Dooley from Birdlife Australia. Sean has been involved with Birdlife Australia for many years and is an expert on our local birds and ways to accurately identify them. Sean and Marie will be discussing Birdlife Australia's impressively large citizen science project, their annual Aussie bird count which has just been launched. This year's count will be from 20th to 26th October.

Last year 57,000 participants counted a total of 4,117,293 birds in a week. Go to https://birdlife.org.au/ to download information and register now for the count. The birdlife app registers your location and count. It has details of birds and their calls which is helpful in identifying birds.

Sean has written for TV comedies including Spicks and Specks. His first published book was 2005's The Big Twitch, an account of his attempt to break the Australian record for the number of birds seen in Australia in a single year. He has written for The Guardian, the Sydney Morning Herald and The Age. He is the editor of Australian Birdlife magazine.
