Northern Cardinals, scientifically known as Cardinalis cardinalis, are mid-sized songbirds renowned for their bright red plumage and beautiful melodies. Known for their distinctive crest and black 'mask' on the face around the bill, they present a striking contrast to most other birds. Male Northern Cardinals boast brilliant red feathers all over, while females flaunt a more subdued palette of browns and grays with hints of reddish hues. One common trait among both sexes is their sharp, stout beaks which come in handy for cracking seeds—their primary food source. While they're primarily found across eastern and central North America, these non-migratory birds have expanded further westward over time due to milder winters. Versatile in habitats, Northern Cardinals can thrive anywhere from woodlands to backyards. Their enchanting song—often described as a clear whistling featuring several repeated notes—is another defining characteristic that makes them unique among avian species. This makes the Northern Cardinal not just visually appealing but also music to one's ears!
