Acanthis is a genus of small songbirds belonging to the finch family, known scientifically as Fringillidae. These birds are primarily found in the northern regions of North America and Eurasia. Acanthis species are characterized by their conical bills, which are well-suited for cracking seeds, and their vibrant plumage, often featuring shades of red and yellow. The most recognized species within this genus include the Common Redpoll and the Hoary Redpoll. Acanthis birds typically inhabit open woodlands, tundra, and scrub areas, where they forage for seeds and insects. Their social behavior often leads them to form flocks, especially during the winter months.
