Calling all Birding the Net fans, let's see if you learned anything. Below are photographs of all the birds in Audubon's social media exercise. How many can you identify? Answers are at the bottom. If you want to share your score, feel free to post it in the comments (be honest!). And if you didn't play Birding the Net, this might also be a good test of your identification skills. Good luck!
