The common redpoll (Carduelis flammea) reaches 13 centimetres long and is a frequent winter visitor to backyard bird feeders throughout southern Canada. During the breeding season, the common redpoll can be found in subarctic forests and tundra. While its body is various shades of brown, a red cap and black chin are notable. Male redpolls will also develop a rosy-coloured breast. Gardens with trees that produce catkins, such as birch or alder, as well as offerings of sunflower seeds and mixed birdseed will help attract these wintertime visitors from the far northern reaches of the country.
