Urban Migration

As the first snow hits the ground, a cast of characters returns to the stage for the seasonal show of urban household bird-feeding in the backyards of this small Ontario town.

Numerous bird species (and squirrels, chipmunks, etc) have come to rely upon the generosity of humans in the form of sunflower seeds, grains, and suet to make it through the cold days ahead.

In one hour on a Spring day in one small backyard a total of 22 species appeared. And now the first of them – a female cardinal, has returned.
