I took this class last semester. I found it extremely easy because the prof KNOWS it's supposed to be a bird course and he says this many times.
I only went to about 3 classes, but didn't find them useful so I stopped going and only showed up for the tests and exam.
My study pattern was to look over my notes for about 1-2 hours the day before each test. Overall, I got an 11. It's multiple choice and most of the questions are very simple. He says he wants you to understand the basics and will never ask for specific dates or anything.
