This maggie attacks all year round. If you walk your bike and take your helmet off, it won't attack you I was told by locals.
If you are attacked and come off the bike take your helmet off and walk your bike to safety away from the magpie.
6pm attacked with high shrill clicking sound for a fair distance from corner Munyang and Park Streets to shops in Snowy Avenue. Also attacked at 7.30pm going opposite way but did not traverse up Munyang Street
Group of three low skimming attackers working in a team swooped constantly. I recovered geocache in the park, then got multi swooped again by the black & white team of three as I was leaving the park on bicycle.
Riding my bike on /walking/bike path in chipping norton lakes, magpie attacked my helmet and swooped several times... I changed route and went back on road and got chased again,magpie chasing me and swooping hitting helmet say 5 times.. Might have been same magpie.
