We now move into a new bird of prey species: the falcons, and our first falcon is the one you find on a Canadian stamp. Why? Just look at the North American distribution of this bird from the All About Birds website:

The Gyrfalcon (Falco rusticolus) (gyr- is pronounced as in: jeer) ranges over the whole of Canada, but just because it is largely Canadian in North America doesn't mean it cannot be found elsewhere in the world.
