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

Wondering how Northern Cardinals raise their young? Both parents share the role of feeding their nestlings a diet of insects just like the family in this video. It takes about 9–11 days for the young to leave the nest—and once they do, the male may continue to feed them while the female begins their next nesting attempt of the season.
