Reviews of "How to Study"

I just want to thank you for a great tutorial. I'm a beginning birder, so the quick & easy approach is the one I usually do. But, I found the fanatical/professional level enlightening. Thank you for recommending the websites you use, especially xeno-canto. I'm terrible at recognizing different songs and calls. Xeno-canto should help. Please let me know when you put together more tutorials.
