Explanation: DO NOT click on the above photo UNTIL you have taken the quiz!

Four different species made these cavities that all appear generally alike ... oblong holes carved for the purpose of nesting and/or foraging.

This is a lesson in convergent ecological behavior ... how such organisms in diverse locations, ecosystems, and taxonomic groups can serve as similar ecosystem engineers, creating similar habitat structures.

Need I say it? Nature can be surprising and always amazing.
