SUNDAY:  When we got back home at 12:30 lunchtime there was a lot of activity at the nest on our back porch.  The Mother bird had apparently just fed the two babies, and she was fluttering around the area.  The larger of the babies was sitting on the edge of the nest flapping wings fast.  I thought we were about to witness the leave-taking, but the little guy just settled back into the nest next to his sibling and stayed that way for the rest of the afternoon.  We went out again for a couple of hours in the afternoon, and I expected, of course, the bird to have flown the nest by the time we came back home.  I was wrong again.  The older sibling seems to be caring for  the younger one.  We’ll see what happens in the nest tomorrow.  The older baby is clearly ready to fly away.  It can flap its wings with as much strength as an adult bird does.  This afternoon it sat on the edge of the nest and demonstrated its strength by flapping its wings vigorously
