Discover the fascinating lives of Australian birds
Hi, I’m Kirsty Costa.
I’m the host of Weekend Birder, Australia’s most listened-to nature podcast.
Birds are part of our daily lives. They share our spaces, from backyards and local parks to suburban streets, waterways and beaches.
Weekend Birder brings their stories, behaviour and science to life, revealing just how much is happening around us.
Whether you’re completely new to noticing birds or you’ve been birdwatching for years, this website is for you.
