I will give it a try. Thank you. I don't want to harm the bird in any way I'm just scared of being injured. Last year a few towns away from me there were several Hawks that were swooping down at joggers and most of them suffered concussions and other injuries. My son is only 3 so if that hawk hit him ugh I can't even imagine!

But why would a hawk attack ? There must be some reason. Nobody reported it to the local authorities?

I have no idea why, especially since everything I've been reading online seems to say that they don't attack when a human is around but this one is without a doubt swooping at me! If it's just trying to scare me it has certainly done so. I called the local animal control to report it and there response was there hasn't been any similar reports in my area so they will make note of my complaint and if they receive more complaints from this area they will come out to take a look.

Yes , there've been reports of hawks attacking people, but only when walking too close to their nests. I also read that some fancy pigeon breeders will hang something shiny like mirrors, CDs or similar near the coops and feeders, as the glare will disturb a hawk's vision. I myself I placed a CD at my window, we have plenty red tailed in NYC, and one had tried my windowsill where I put seeds occasionally. It's been working.

You're not willing to hurt the hawk, but you are willing to live in terror and possibly the allow the hawk hurt you, your child, or your newborn. Is that right?

I like birds and have had parrots and parakeets as pets, but they are just birds. I refuse to live in fear of what a bird might do. I live on a golf course in the country. Crazy animals are the reason I have weapons. For crazy birds I have a reasonably powerful, small bore, air rifle. These things are accurate enough to repeatedly shoot a quarter at 20 yards. Head or neck shots on birds are pretty easy if they sit still for a few seconds. I'm getting ready for the return of the crazy swallows. I tolerated them for two springs, but last year was the end. Messiest birds around and get a little crazy when you get close to their nests...which are made of mud and are attached to your house.

Some hawks (notably Coopers and Redtails) will swoop to defend a nest area. Hanging some CDs or cloth streamers around the porch for the duration will distract them from you. Hardhats also help.

"Boekweg described how the Cooper’s hawks attacked each of the victims.
The hawks will usually swoop from behind and slap the back of the
victim’s heads with their wings and then fly off."

You can ask your state Fish and Wildlife to remove the nest after the nestlings are fledged and gone if the birds are persistent. Two years is definitely persistent.

Buy some inflated balloons at the dollar store. Tie some on porch railings and other obvious spots. Move balloons around to different trial locations if needed. I use this method to stop birds from pecking on my ripening tomatoes every summer. Hopefully this method will work for you.

You definitely have nesting hawks in the neighborhood. This isn't an unusual problem anymore with the urbanization of some species, notably Red-shouldereds, Mississippi Kites, and rarely Cooper's or Red-taileds. Lazy-gardens had the best advice above- you're going to need the nest removed after the young fledge (federal law protects active nests).

All the Cooper's and red-tailed hawks have come to NYC then We have an amazing high number of them , especially the red-tailed

I'm slow to the party, but I wouldn't use a fake owl to scare away hawks. I've helped our local raptor expert band Cooper's hawk chicks, and to catch the parents, he uses a stuffed owl next to a mist net. The hawks dive the owl like crazy! Putting one on your deck may be more likely to incite them than scare them off (assuming there is a nest nearby).

.....yes, but only when the nest is there. Otherwise a hawk would not go close to an owl, specifically the great horned, being one of her few natural enemies together with other larger raptors. Obviously it also depends on the size of the hawk.

I noticed the date of your post.... you're likely dealing with a hawk with a nest nearby, which is the only time they ever do these warnings. People get too close to the nest and, just like any of us humans would do for our babies, they go into protection and defense mode. They're not trying to hurt you, but to keep you from hurting their young. Once hatched the adults won't care anything about you. A red-tailed hawk will fledge about 42 days after hatching, but the adults will protect the nest during incubation as well. Just be patient.... they're not trying to hurt you. Find out what kind of hawk you're dealing with and steer clear of their nest and nest tree. And trust me, they gave warnings long before they started dive-bombing.

NOTE: All hawks and owls are federally protected under the Migratory Bird Treaty Act (16 USC, 703-711)... bald eagles are protected also. Even vultures are protected by Federal law.
