The ABA checklist 8.0 was released yesterday! This update includes Hawaiian birds and syncs up with the AOS checklist that was released in July. I have updated Birdathon to include the new ABA Checklist, which completes the last big task planned before announcing Birdathon to the world. More information on the ABA checklist is available on the ABA blog.
So hello, world! Birdathon is ready for you. Well, hello birding world anyway :-).
