If you submit a photo of bird when you’re adding a sighting, by default it will appear to other users of the app in the Explore section's Photo Feed.
To add a private photo to a sightings:
If you would like to keep your photo private, tap the photo after you’ve added it
Select "Keep Photo Private"
The photo will have a filled in eye next to it indicating the photo is now private to you
You’ll still be able to see this photo in your My Audubon section, but, it will be hidden from Photo Feed
*Note: Please keep in mind that photos in Photo Feed show up with your username and your chosen location name for the sighting with the photo, but no specific location data.
