The Redpoll (Acanthis flammea) is a small and hardy finch, a fascinating bird known for its resilience and charm. In older bird identification guides it is listed as the Common Redpoll, with the almost-identical Hoary Redpoll as a different species.
Recent taxonomy changes have settled on a single inclusive species in North America. These birds thrive in the cold, boreal and tundra habitats within the northern regions of Europe, Asia and North America. Their winter appearance in Carver County is inconsistent, so when they show up, it’s always a treat! Their seasonal southerly movement is tied to widespread failure in seed-crop production among high-latitude tree species.
Characterized by their petite stature, redpolls measure about 5 to 6 inches in length, with a wingspan of 8 to 10 inches, similar to Goldfinches. They are identified by their streaky brown plumage, a tiny yellow bill, and the bright red patch – or “poll” – atop their heads.
Males often display a rosy flush on their chest, adding to their vibrant appeal. Females lack the red chest. Male house finches and male purple finches may also have red breasts but are larger and have thicker dark bills.
Redpolls are well-adapted to cold climates, adding thick plumage in winter. They have a unique physiological trait: the ability to store food in their esophagus. This adaptation allows them to feed quickly and later digest the food in a sheltered location, conserving heat in frigid conditions.
These birds primarily consume seeds, particularly those of birch and alder trees. Their acrobatic feeding behavior, often observed as they dangle upside down from branches, is both efficient and entertaining to watch.
In winter, small flocks of redpolls visit backyard feeders, delighting bird enthusiasts with their sociable and energetic nature. Thistle/nyger seeds are right-sized for their tiny beaks, but Redpolls will also eat pieces of sunflower seeds that have had their shells removed.
Redpolls are not known to breed in Carver County or anywhere else in Minnesota.
Despite their northern range, redpoll populations appear stable. Observing these lively finches is a treat for birdwatchers, as their resilience and beauty embody the spirit of the wild.
