I just finished my review of Molt in North American Birds. Loved it. As you would imagine, it will be a great resource to learn about molt. It's worth it just for that (perhaps even for birders outside the US and Canada, the region it focuses on). But I was surprised at how interesting and readable it was. Honestly, I was expecting it to be a little tedious and, dare I say it, boring. But there are so many fascinating details in each of the family accounts, I found myself wanting to keep reading more. Highly recommended to non-beginning birders, especially those in North America.
