Join sound recordist Greg Budney in our Video of the Week and learn about one of the first sounds of spring: the wonderful whistled song of the Northern Cardinal. Both male and female cardinals sing, and their songs bringing a cheerful sound to the gray days of late winter and early spring. | Cornell Lab of Ornithology

Cardinals are easy to attract to backyard feeders throughout their range—especially when sunflower seeds are on the menu.
