Sibley Birder's Trivia

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 400 questions 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 questions 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.
