Last fall, while I was in the circuit to land at Toronto Buttonville (CYKZ) airport, I was listening to the tower controller who was giving a running commentary and warning to pilots on final to watch for Canada geese that were flying back and forth over the threshold of the active runway, creating a very nasty bird strike hazard. After the controller had made the warning for the fourth time in a very short period of time, she again repeated it to me as I was short final -- in a very frustrated tone. I decided to try and lighten the frustration to her day.

Cessna Amphibian 1234:
"Can't you just give those geese a transponder code?"

Buttonville Tower:
"They won't comply!"
