We had a lot of great answers for this week's mystery, in which my Screech Owl Companion co-author Scott Weston asked: What is this a picture of?

Answers included owl pellet, praying mantis egg casing, and kingfisher pellet.

The correct answer, from Mia Rose White and Jack Duhig: kingfisher pellet. (Congrats, Mia Rose and Jack.)

I love this illustration, from an antique ckidren's book in the fascinating Ridgewood Schoolhouse Museum.
