Why bird nests aren’t covered in poop, explained to kids

An ornithologist explains the wonders of fecal sacs.

Earlier this year, I noticed a bird nest with a single bright blue egg sitting on my front porch. A few days later, there were four eggs, and in a few more days, the eggs hatched. What I witnessed over the course of these baby birds growing up was magical, but the experience also left me with a lot of questions about what goes on in the beginning of a bird’s life.

My biggest head-scratcher: Where does their poop go?

To answer all of my questions about these hatchlings, I spoke with professor of biology and lifelong bird lover Michael Murphy about the weird and often gross things birds do to survive.
