I think the small birds would get it before the big, aggressive ones. And then I also saw large flocks of seagulls 15 miles inland, over the coastal mountains. Those are not small birds either, and they are wild and aggressive. They leave 3-4" diameter spots of shit on your vehicle. Nasty, filthy birds. For some reason, one came at me while I was coming home from work one day. I just slapped it away while it was airborne. Do birds get rabies?
