House Wren hatchlings have prodigious poop output. That’s just one of the many visual discoveries I uncovered while spying on a nesting box for the past few weeks. A confession is in order: I do not consider myself a birder. And I do not keep “life lists” of bird species as so many birders do. But when any wildlife species sets up housekeeping near me, I take notice and observe. In the case of these House Wrens, they moved into an old nesting box I had installed three years ago against the interior wood frame of my arbor, a site I use as my outdoor office and an escape from city life. The nest box is less than ten feet from my arbor desk and that gave me a bird’s eye view of their life, including diaper duty. For like all newborns, things poop. Some more than others.
