Re #2 - Crows make so many different sounds!

I "think" (since I don't have the ability to tag) that I have had a pair who had two babies who are currently regular visitors. There was a new baby this year. I remember when the two babies were young and hung out in the back yard. You could see their cute young bird head shapes and watch their their games. One would carry sticks around in a way that made me think that she was "playing house." The chickadees and oak titmice that come bring their babies, looking sleek and plump while the parents look bedraggled, but they became a pair again soon after.

When I put out food, the new kids often come first. They will pick up the food and wait for the parents. When they show up the parent takes it.  The kid the goes into the feed me posture and call, then the parent feeds back to them.
