As always, the “Just for Fun Avian ID Quiz” is brought to you by Jory Langner, our esteemed Avian Quizmaster.  And don’t expect help from the rest of us at 10,000 Birds on this quiz: we are surely as confused as you!

This quiz is quite different and is fully obfuscated.  I’d suggest relaxing, getting a cup of tea and taking a deep breath before starting this quiz.  I keep hoping that there is more than one “right” answer to my quizzes, and perhaps this quiz will be the one!

The question to be answered is at the end of the clues, and the answer will be posted on Saturday (more or less).


  1. One in mammals, instead of two in birds.
  2. One way in birds, instead of two ways in mammals.
  3. One full cycle in mammals, two full cycles in birds.


What else do you know about this subject?  Try not giving “it” away when posting your answers.  Good Luck!

Jory's first field guide-identified bird was a Northern Cardinal. This turned out to be his gateway drug into birding. In 2007 Jory became the least accomplished birder to see 300 birds in New York State in one year. He has birded the world over but maintains his birding "beginner mind", of which he is inordinately proud. Just ask him. Jory is the 10,000 Birds Avian Quizmaster, coming up with ever more diabolical ways to stump his legion of devoted fans. He lives with his wife and the possessions of his children just outside of Albany NY.
