Was I ever wrong about fledging date!!! Two were gone some time yesterday, and I totally missed it. By the time I looked at the rewind today, only a few hours of dark were available and only two were left in the nest box. They are Blue band S over Black band 65 and 66, on left legs. From feathering, I'm guessing that #65 is the youngest because the most white baby feathers.
#66 made the jump at about 7:00 AM. #65 isn't quite ready, and a parent dropped off lunch about 12:30. I think it was the female (larger) and she didn't stay at the box. A few minutes later, another parent stopped by and looked for all the world like "Where's everybirdie?" I'd say this was the male.
Have not see the fledglings, and this camera does not move. So good luck to all, fly high, and have great lives as soaring Spartans.
