A modest thicket of trees along a street can be the perfect place to hear one of the earliest bird songs of spring: the Fox Sparrow. You can hear their loud, spirited songs from dense vegetation throughout much of the U.S. The easternmost birds have the rufous color of a Red Fox. Others found further west are a mix of brown, rust and gray. The stocky sparrow reveals itself by vigorously kicking the leaf litter with both feet. Learn more at BirdNote.org.
