The "Kent" Call

Listen for the ivory-bill’s distinctive nasal tooting call
The Ivory-billed Woodpecker’s call note is a nasal sound reminiscent of the tooting of a toy horn. Some people refer to it as the “kent” call because it sounds as though the bird is saying, “kent, kent, kent.”

The only definitive recordings of Ivory-billed Woodpeckers were made in 1935. These recordings help researchers know what to listen for as they sort through calls from the Big Woods.

White-breasted Nuthatches have a call that is similar, but less powerful. Blue Jays also sometimes make sounds that resemble the calls of Ivory-billed Woodpeckers. Researchers use computer programs to analyze the acoustic properties of the sounds and classify them as most similar to the calls of Blue Jays, White-breasted Nuthatches, or Ivory-billed Woodpeckers.
