Thanks for looking, commenting, and ID-ing, I appreciate it. I was guessing Harris hawk, but it's good to get confirmation from REAL birders, LOL. I keep an AZ bird guide book right by the back window, but I'm still not great, LOL. Thanks again. Nature is wonderful isn't it? Happy gardening! Grant

I agree, immature Red-tailed Hawk. BN

The big birds are most likely Turkey or Black vultures; the hawk probably a Cooper's hawk. :)

You can't disturb a nest once it has eggs in it. If you at all prevent a hawk from raising it's young, it's called a 'take'. The hawk may or may not abandon the nest and the young may or may not get the food they need to grow and if any of the disturbance is your doing, US Fish & Wildlife will be secretly filming you and trying to build a case. Many people get on a 'witch hunt' over hawks and 'their rights'. It's a small minded neighborhood thing because many view the hawks now as cool thanks to nest cams. My advice is to remove any tall trees that would be an ideal nesting site if budget allows, or make them unappealing before nesting season by paying a tree climber to add a fake racoon or fake owls that move, or other bright, big objects that move such as huge balloons with eyes, large shiny pinwheels with tape that flashes in the breeze. Add several so as to overwhelm the hawk as it first approaches it's old nesting area. It may not stop the hawk from coming to the area but may pursuade it to nest elsewhere. Just make sure that the type of hawk you're trying to encourage to move isn't considered endangered in your area. Your local game commission may have that information. A pic provided to them will be helpful. I know red shouldered hawks are becoming more scarce due to red tail hawks taking over good hunting and nesting grounds. Just check with your local authorities before taking any action.
