Deleting an unsubmitted checklist in eBird Mobile
Go to the home page, and then to My Checklists. All of the lists that you've entered in eBird Mobile can be found here. If you're using an iOS device, at this point all you have to do is swipe left, like you would with a text or email—and press Delete! Easy as can be. For Android, press-and-hold on the name of the checklist, and it will pop up a window that lets you delete the list. WARNING: Make sure that your list is marked as "Accepted", otherwise deleting it will irrevocably remove those data from eBird. There will be warnings about this in the app as well.
