They were hanging around earlier this week. I ran down to the local place that carries live mealworms in hopes of convincing them to stay, and later that day they cleaned out the mealworm feeder. So I placed a bulk order for live mealworms, and put another bunch from the local store in the feeder.
Course, I haven’t seen the Bluebirds since. But I know they’re in the area, so I’ll keep at least a few mealworms in the feeder and keep an eye out!
