Red Tail Anyone?...

Has anyone seen our neighborhood red tailed hawks, lately? It has been a couple of months since last sighting them and they use to fly over head daily in all of their majestic glory. They were residents of our immediate neighborhood for several years, keeping an eye on all below. I heard them making a big commotion a while back when I was in the office and have not seen them since. I am feeling lost without them and I need that sense of wild around me while I live in this concrete jungle.
