Similar taxa

  • Animalia: Common Nighthawk (species: Chordeiles minor)
    Lesser Nighthawks are easiest to distinguish from Common Nighthawks by the white bar on the wings. In Lesser Nighthawks the white wing bar is closer to the tip of the wing, leaving a dark equilateral triangle for the wingtip rather than the longer, isosceles triangle created by the white bar of a Common Nighthawk. Lesser Nighthawks also typically have somewhat more rounded wings than Common Nighthawks.
