Feel free to share your photos and other birding-related content here. If a photo you post isn't yours, please credit the original creator! Additionally, it would be appreciated if the location of the sighting and a date were given when a photo or question is posted. You do not have to give the precise location, something like "Northern Idaho, June 2023" or even "North-Western US, June 2023" suffices.
