We always have a resident red-tail hawk that lives in the woods. This year there were at least two juveniles. For the last few weeks we have been listening to the young screeching for their mother. I am thinking it is their call when she is out hunting for their food or just because they can!
One is so vocal we have named her/him Crybaby.
The first picture is of the adult.
Now you can see the difference of the juvenile. He does not have the red-tail or other colorings yet.
