Thanks for your question about the hawk in your backyard. I wish there was a picture so I could see what species it is.
While I can’t say for sure that anything is wrong with it or not, another possibility might be that it is an immature bird. In my opinion, some immature birds that have recently fledged aren’t very smart and haven’t yet learned to be wary of people. I have walked right up to immature woodpeckers at my bird feeder and they just stayed there looking at me. So that could be the case with your hawk.
In the future, unless it appears injured in some way, I wouldn’t interfere with it.
