There’s a solar panel on the roof of the birdhouse that collects enough energy to power the glow-stick at night to encourage birds to check it out. The simplicity in design is wonderful and all. The stick is not just a standing stick, but it’s a wayfinding device, bla bla bla. But I say take this idea one step further and have the solar panels charge up enough energy to power a big “MOTEL” sign on the bird house.
