070 SPRING SONG - YELLOW WARBLER
Yellow Warbler - Black Hills, South Dakota. In mid-May, a yellow warbler sings its clear sweet song from a perch near a quiet spring-fed stream in the southern Black Hills. During a brief period in late spring, a continuous parade of warblers and other songbirds migrate through or return to nest in the Black Hills region, clustering in shrubby areas along secluded river and stream valleys before heading to nesting territories. Yellow warblers will build nests out of milkweed fibers, grasses, spider's silk and down from willow seeds, in the fork of a shrub or small tree. After chicks are fledged, the warblers will begin their migration southward as early as late July.
