Birda automatically creates a number of time and location-based life lists so that you can easily keep track of your sightings and progress. If you choose to input your home location, then you will get a Home list (40m radius) and a Patch list (10km radius). We’ll automatically add the birds you log within these radiuses. This privacy zone is also there to provide an extra layer of comfort and means the exact location of sightings at, or close to, your home are hidden to everyone except you.
