INTERESTING FACTS

  • The Bridled Tern was long thought to be a casual visitor to the North American coast, but as more birders travel out to the Gulf Stream, it has become evident that they are fairly common 20 or 30 miles offshore.
  • They may be establishing a breeding population in the Florida Keys.
  • A group of terns are collectively known as a "ternery" or a "U" of terns.
