On the left, a Northern Cardinal - on the right, a European House Sparrow. QED.
Even the female Cardinal is reasonably colourful, for a girl. Their winter range is apparently spreading north-eastwards, helped no doubt by backyard feeders.
The Blue Jay needs little introduction, and no second invitation to scoff sunflower seeds on the deck - up to eight were seen at a time.
And finally an endearing, trusting Black-Capped Chickadee-dee-dee. Canada's a great place for birds - I hope to return soon.
