There is an upscale neighborhood here in OKC, actually it is it's own township in the middle of OKC, Nichols Hills, that has so many of those birds nesting they named a park after them, Kyte Park. And yes, they are very aggressive at times. The resident joggers and such complain of getting dive bomb attacked by them. There are even bird warning signs up in the area.

A few years ago in another part of town they were setting off fireworks to try to keep them from roosting in a shopping mall. There is a pretty big flock that roosts in the few trees in the parking lot at the local grocery store this time of year. The trees look like they are in the movie "Birds." Haven't personally noticed any aggression, but park away from the doo drop zone.
