Common Nighthawk Identification

The Four Keys to ID

  • Size & Shape

    Common Nighthawks are medium-sized, slender birds with very long, pointed wings and medium-long tails. Only the small tip of the bill is usually visible, and this combined with the large eye and short neck gives the bird a big-headed look.

    Relative Size

    Slightly smaller than an American Kestrel; larger than a Purple Martin.
