Chickadees make their chickadee-dee-dee call using increasing numbers of dee notes when they are alarmed. They also have a gargling call, often given aggressively when a lower-ranking bird gets close to a higher-ranking one; also exchanged between members of a pair. Black-capped Chickadees make a high pitched see as a high-intensity alarm call, often when a fast-approaching predator is detected. When chickadees hear this call, they freeze in position until they hear a chickadee-dee call signifying all clear.
