The Dark-eyed Junco is Canada's unofficial bird of winter — when juncos appear at your feeder, you know the cold season has truly arrived. These charming, slate-grey sparrows with crisp white belly feathers and flashing white outer tail feathers are among the most common and recognizable backyard birds in the country. They forage almost exclusively on the ground, hopping and scratching through snow and leaf litter in busy flocks. Juncos breed across Canada's boreal forest and mountains, then flood southward in fall, making them a welcome and familiar presence at feeders from coast to coast all winter long.
