Redpolls are small, brown-streaked finches found across Canada and the northern United States. These flocking birds move quickly between fields, forested areas, and backyard feeders. During their migration, flocks may swell into the thousands.
Their diet consists primarily of seeds from the trees they frequent, but they will also eat grasses, wildflowers, and insects. Although they nest in trees, the nests tend to be low to the ground. In the far north they may build nest on logs, ground cover, or rocky outcroppings. This northern bird may even roost under the snow in tunnels during the harsh winter to stay warm.
