True or false- Many dinosaurs (the ancestors of modern birds) had feathers.

If you answered "true," you just won a point playing this ultimate ornithology trivia game. Sibley Birder's Trivia offers 400questions that will test your bird knowledge over five rich categories- Bird Identification, Bird Anatomy and Physiology, Bird Names, Bird Behavior, and Birds in Culture. The types of question vary- Q&A, true or false, and multiple choice. Each card offers two questions in a category, one easier and one harder. Players can choose which one they want to answer; the easy question is worth one point, while the hard one is worth two. If you answer the easier one correctly, you can move on to the harder one.

Some of the questions about identification are illustrated with Sibley's vibrant bird portraits drawn from his authoritative work, The Sibley Guide to Birds, Second Edition. You can play in teams, one-on one, or alone by pulling random cards to test your knowledge. No matter how you play, in the end, everybody wins as they learn hundreds of fascinating facts about birds.
