The Clements Checklist of Birds of the World. This is one big-ass birding checklist! I had no idea when I ordered it how big and all-encompassing it would be. It’s nothing but the list. Of every bird known in the world. The Amy Farrah Fowler in me squealed with delight over the idea of such an organizational undertaking. Then, I realized how few birds I have actually seen in the wild and how many I need to see, how many I’ll probably never get to see. Sigh.
