In this discussion, tempo refers to the overall “pace” of the song, the number of notes or phrases per second. We describe this as fast or slow, and over the course of the whole song the tempo can be steady [...]
posted May 7th, 2012; last edited May 7th, 2012 –– David Sibley Like a previous quiz this one shows warblers as they are so often seen in the field – with just the underside of the body visible. Clues such as tail shape, overall size, behavior and other subtleties can be very helpful with experience. In this quiz I focus on the more objective features of plumage. [...]
posted May 2nd, 2012; last edited May 2nd, 2012 –– David Sibley This quiz shows just the bodies of five species of small drab songbirds with wingbars. In other quizzes I’ve given a big clue in the form of telling you the family of the birds in the quiz (e.g. “More Warblers”), but in this quiz your challenge is to identify the family.
This level of identification [...]

The still-unidentified Elaenia, found by Ethan and Aaron Gyllenhaal in Illinois, has provided one of the most exciting and interesting bird identification challenges in recent years. It is either a first North American record of Small-billed Elaenia, or second North American [...]
posted April 16th, 2012; last edited April 16th, 2012 –– David Sibley I was musing on the value of learning bird topography this morning, wondering why it is so important to know the greater coverts and supercilium and all the rest. The easy answer is that it gives us a framework to describe the color patterns of birds, but I think there’s even more to it than [...]
