I know there are at least 2 still there, possibly the third one also.
I see “Mom” or “Dad” flying away from the nest with a ball of white, every now and then. I believe this is the babies droppings. When I had the orphan baby wrens for a night, it was easy to clean up after them. The droppings were like a small bag of white. Nature has a great way of taking care of itself.
I can see the nest from my easy chair. I have to keep a close watch if I want to see them leave.
I really like these little Wrens. They are not as pretty as the Indigo Buntings or the Painted Buntings, ( I have one coming to my feeder now) that spend the winter here…but they are still a cute little bird and fun to watch.
