You think that's bad? At Brisbane airport (popular ride) there's one that starts in June and keeps going till January. It's a real [censored] too. It doesn't just attack near it's nest (if it has one)... it keeps attacking for about a hundred metres or so along a flat where you can be doing about 40km/h. I think it's a bit long long (pigin for mental).
Yeah, we had a different one just outside lismore that would divebomb till mid december. I don't know how he did it coz he only had about 3 flight feathers left, he was that ragged and would flap around for ages trying to swing around for another pass.
