I'm presuming this is the same hawk we see occasionally. It has been 2 months since I last saw him (her?).
There was a Blue Jay who would pop down from the pine tress and sit about 10-12 feet away, stare at the hawk for 5-10 seconds, then pop back up into the pine trees. And repeat maybe 30 seconds later. He (she?) must've done it or 9 times, the hawk never paid any attention.
