The "Starling-proof" Flicker box that we built and hung did not attract the species it was designed for, so I decided to change things up a bit and hung the Troyer that I built in that spot. I saw a Downy checking it out and packed it tightly with wood shavings in case she wanted to excavate a roosting spot. Then, a differently looking beak showed up and started to get to work. A House Wren! It started taking the shavings out, one by one, hyperactively, and now has begun to bring sticks in. Wrens have nested in that spot before and I am happy to see them back. I don't want to tinker with the door to restrict access to larger species now, so we will have to see if the Troyer style works out. At least with the camera I can monitor precisely.⁠
