Snow bird, usually a descriptor for northerners who’ve moved south, is used here in reference to birds like Snow Geese. Flocking to North Carolina spots like Lake Mattamuskeet between November-February, Snow Geese prefer such areas because of land and water availability of plants like corn as well as the temperate winter weather.
Several species of birds’ native to the western part of North Carolina change locations for the winter; some migrate south to warmer climates while others, such as the Dark-eyed Junco, head down to lower elevations.
