We had a baby HB yesterday that came to the feeder, then flew close to the ground and between two square planter boxes on the porch and appeared to be practicing aerial maneuvers. He would fly one way, pause and then do a snap 180, fly back, pause and then another zip 180 rapid turn. It did for for maybe 45 seconds and then flew off. No question it was learning how to fly. Very cute and never saw that before.
We went from almost no visits prior years to a banner year last year with thousands of visits and hopefully what is a repeat of that this year. I think the attention to changing and keeping fresh food in the feeders regardless of how many showed up has helped. Not totally sure but think you just have to keep at and they will come.
