Heading north on the Southern Expressway Bike Path just before Peppermint Grove bridge. He swooped twice. I could hear the snap of his beak but it sounded well above me. Not very aggressive.
Whilst climbing up from Greenhill Rd, right on the corner of Tanahmerah, I was swooped by 2 maggies, both of them just kept coming and coming. Managed to hit one of them with my hand as I swung it above my head.
The only bonus is I managed to PR the strava segment trying to get away from them! :)
