The birds were too intent on eating the grain someone had put out for them to bother much with people, but even so, I kept one eye on the view finder and the other one on the view, as geese can give you quite a good bite if they want to. My grandmother used her geese on the farm as watch dogs. Turkeys make good watch dogs, too, come to think of it.
This long necked swan was warning off the interloper -- for a moment, I thought they might come to wing-blows. With the temperatures in Port Credit (which is often warmer in winter than more northerly areas of Mississauga) hovering just above freezing during the day, and dipping below zero at night, the birds might be thinking it's time to start this year's family.
I hope not, as Spring is not watching the calendar this year, and is not likely to appear for at least another month. For while this type of weather perfectly suits maple syrup production (photos), it's definitely not suitable for cygnets!
