Adult upperparts are black in the male and gray in the female. The male has bright orange patches in the tail and wings; female's patches are yellow. Underparts are white with orange patches on the sides of the breast in the male, yellow in female. Voice is varied but is usually a high series of single or double "see see see" or "seeta seeta seeta" notes, with an up-slurred or down-slurred wheezy note at the end. Call is a musical "chip." Redstarts flit among tree branches, drooping their wings, fanning their tails and leaping into the air to catch insects.
