A bright green insect hunter with a long bill and triangular starling-like wings. Adult has a bright blue throat, orange-brown crown and nape, and long trailing central tail feathers. Sexes are alike. Juveniles have a paler blue throat, no orange-brown coloration, and no long tail extensions. Often hunts from exposed perches such as telephone lines or snags, on which it rubs its venomous quarry so as to disarm it.
