I'm riding south on Burrows Road in Tempe yesterday about 3pm, slowing down for the red light before the right turn into Ricketty Street toward Sydney Airport. As I get to within 30-40 meters of the intersection, something or someone nudges/pokes me behind my left shoulder. What the ..? What the hell was that? I pull straight to the side and look around. There's no-one there, not even any cars following me. There's no breeze. I feel around behind my shoulder for flaps on my jacket that are loose. Can't feel anything. How bizarre. I rev and start to pull back into the lane. NUDGE! Very concerned, I stop again, get off the bike, take off my helmet and jacket. I examine the jacket closely, but nothing is amiss. There's still no-one around, very few cars, and no nearby bushes that some nutter could be jumping out from behind to poke riders as they go past. But I felt something, so what to do? I have no idea, so I stand there for several seconds, completely confused. Out of ideas, I get back on the bike, and start to move. NUDGE! Now I'm doubting my sanity. Could yesterday's off have affected my brain somehow? Hope not! And I don't believe in ghosts, particularly not ones who spend their time outdoors around industrial estates on bright sunny days. I angle one mirror toward my shoulder where it's occurring, hoping to catch a glimpse of something, and slowly accelerate toward the intersection. After a couple of seconds the mirror is filled with movement – NUDGE – and I see a mass of black and white feathers disappearing upward. It's a damn MAGPIE! One with a particular thing for motorcyclists, but amazingly seems to only go for ones who are moving. He/she never touched me when I was stationary or off the bike. I laughed so hard when I realised – it would have looked so funny to anyone watching, with my futile attempts to work out what was going on. Maybe I'll go back there and get a friend to film a recreation for YouTube or Funniest Home Videos.
