I was swooped by a magpie that made no noise ie no clacking of beak or wing noise and so took me by complete surprise. He made contact below my helmet. Luckily I was wearing a headband under my helmet as contact was made with his beak and I suspect he would have broken the skin otherwise. A friend was also swooped by the same offending magpie and he made contact with her helmet and head numerous times. Avoid riding along this stretch of road if you can.
This guy is defending a few blocks it seems. Chased me about 150m with at least 10 swoops. Often makes contact, and doesn't care if you're looking at him. Only seems to attack cyclists.
Might be a couple in the area, or just one super aggressive one.
Walking down Roslyn Street close to home and was attacked from behind. The bird smacked into my head really hard using its full force. It then flew onto a tree in my driveway and sat there.
