INTERESTING FACTS

  • The Vaux's Swift is the smallest swift in North America. They have more varied calls than others in their genus.
  • It is named for William S. Vaux, a member of the Academy of Natural Sciences and a friend of John K. Townsend, who first described the species. The name is pronounced "vawks," not "voh."
  • They roost communally, by the hundreds or sometimes thousands, presumably to conserve heat. They let their body temperature drop and become torpid on cold nights, reviving in the warmth of day.
  • A group of swifts are collectively known as a "box", "flock", "screaming frenzy", and "swoop" of swifts.
