The American Tree Sparrow is a common winter visitor in backyards all across southern Canada and the northern United States. Despite its common name, it forages on the ground, nests on the ground, and breeds primarily above treeline in the far North.

Small songbird.
Rusty brown crown and eyestripe on gray head.
Dark spot in center of unstreaked breast.
Two white wingbars.
Tail rather long.

Size: 14 cm (6 in)
Wingspan: 24 cm (9 in)
Weight: 13-28 g (0.46-0.99 ounces)

Other Names
Bruant hudsonien (French)

Cool Facts

During the summer, the American Tree Sparrow eats nearly 100% animal matter (mostly insects). In the winter it eats none, turning then to eating entirely seeds and other plant foods.

No one knows just how many American Tree Sparrows exist. But they breed across a vast expanse of northern Canada and Alaska, approximately 100 million hectares (247 million acres). If the area is about 10-20% filled by tree sparrows, and they have 1-ha territories, as is the case near Churchill, Manitoba where they have been well studied, then approximately 10 to 20 million pairs should be breeding.

A study found that the American Tree Sparrow seems to prefer to look for predators out of its left eye. This preference may be because the right hemisphere of the brain is dominant for processing visual information. Oddly, the Dark-eyed Juncos examined in the same study preferred to look out of their right eyes.
