A note from Jack:
Some excitement this morning on the nest. I was about to go our for a little break at around 10:00. I looked out and saw some movement just below the nest. Upon further investigation, I saw that a squirrel was in the branches just below the nest. I continued to watch as the squirrel moved closer to the nest. About the same time the male hawk did a fly by but didn't come to the tree. As the squirrel came closer to the nest the female on the nest must have heard the squirrel and she became really big with her wings spread and I can only guess that she voiced her complaints as well. The last I saw, the squirrel backed off. I will let you know if anything else happens.
