If this was a wild mammal of any appreciable size, animal control would have already shot it... Curious that we seem to tolerate birds being pissed at us for ... but for many other animals we bring out the murder machines.
It's for the same reason that we have dog catchers, but not cat catchers. Birds are not considered a possible threat to your safety, just a minor nuisance.
However, if you had an ostrich running at people like that, we might make an exception...
