This morning one of the babies was on the concrete under the casaport. I watched the parents pay close attention to it and its siblings.
I tried to put it back in the nest with its siblings, but it did not work out. I had expected them to just hunker down. They did not and instead jumped out the nest. OOPs! Well the one I put back stayed. The other two flew off. LOL. So I am sure they were fine. I expect the one I “rescued” was the runt and will leave very soon.
