Falcons make sharp, high-pitched calls that most people describe as screeches , “kek-kek-kek” chattering, or thin “kee-kee-kee” notes, often repeated quickly when they’re excited or alarmed.

How to Imagine the Sound

  • Think of a shrill, whistling scream rather than a musical song.
  • Many falcons give a rapid “kek-kek-kek-kek” or “ki-ki-ki-ki” when defending territory or reacting to danger.
  • Young, hungry birds often sound like a long, drawn-out wail or “screea” begging call.

Common Falcon Calls (Simple Breakdown)

  • Alarm / territorial: harsh “kack kack” or “kek-kek-kek” bursts, very urgent and repetitive.
  • Hunting / territory marking: sharp, high “kee kee” notes, sometimes in quick series.
  • Courtship / pair communication: softer calls like “ee-chup” or shorter, creaky notes used between partners near the nest.
  • Juvenile begging: loud, insistent wailing or “ghiii-ghiii” style cries when they want food.

Little Real-World Example

If you were standing near a peregrine falcon nest and a stranger walked too close, you’d likely hear a rapid, intense “kek-kek-kek-kek!” as the adult circled and called out in alarm.
