The redstart is one of the most active and graceful of American warblers. The Blackburnian warbler has a bright orange throat. Two other warblers are named for their colors. The ovenbird has a dull orange stripe on its head, a white breast marked with black, and an olive-green back. It is named for its ovenlike nest.
Warblers help farmers by killing insects that destroy fruits and strip trees of their leaves.
Warblers search in tiny cracks in the bark and in fruit buds for insects that might escape larger birds. Warblers make up the subfamily Parulinae in the family Emberizidae. The American redstart is Setophaga ruticilla. The ovenbird is Seiurus aurocapillus. The yellow warbler is Dendroica petechia, and the yellow-rumped is D. coronata.
