The Scissor-tail is often seen perching on a telephone wire with its extraordinarily long tail held out in a horizontal position. Like a kingbird, it erects its crest, emits harsh cries, and fiercely attacks hawks, crows, or other large birds that invade its nest area. In spring, they put on a wonderful aerial courtship display. With their long scissor-like tail, they can maneuver and "sky-dance" gracefully. Nearly all of their food is captured on the wing; included in their diet are many insects harmful to agriculture.
