Every Monday we encounter this magpie which is a regular year after year and starts early in the season. Attacks on our way out to Whittlesea after climbing up from Arthurs Creek and not so much a problem as we start the downhill and can get away. The real problem is on the way back and it attacks as we are climbing and are really slow. Sitting ducks. We counter this be staying together as he tends to go for the lone rider, even if you're off the front. Not particularly aggressive, but persistent.
