Just wait till they hit you ... usually on the back or side of the head.
That's why I put magpies in my list. For about 2 months of the year, out of nowhere these relatively large birds will swoop cyclists, often nailing them on the head. There's a reason we wear helmets!! But sometimes they hit so hard they can dislodge the helmet or draw blood with their beaks or claws.
And yes, cyclists here use various techniques to ward them off. One of the most popular is cable ties (zip ties) attached to the top of the helmet. A lot of cyclists do that, although most I've seen only attach a few ... not as many as in the photo.
