We’re bird quiz-aholics. If there’s a bird quiz online, chances are we’ve taken it. We pore through bird photo Flickr pages and cover up species names to quiz ourselves. On our laptop, you’ll find folders labeled “Wren Calls” and “Warbler Chips,” from which we frequently pop-quiz each other.
Say, which wren’s scold is this?
Okay, is this a Hermit or Black-throated Gray chip note?
