When I’m filling the feeders the chickadees sometimes give what seems like a friendly chick-a-dee-dee-dee which I always interpreted as a “hurry up, food is here”. Then when a Chickadee stops by my feeder they make a tseet, tseet “hello”, picks out a seed and zips away. And the soulful sweeeties chickadee parents call to gather their fledglings is one of the sweetest sounds of summer.
Black-capped Chickadees have a lot of vocalizations, adults can produce at least 16 different calls. Young chickadees usually produce 3 types of calls to beg for food, to talk to their parents, or alert them they are in distress.
Chickadees are well known for their distinctive calls which sound like chick-a-dee-dee-dee. Scientist are just beginning to decode some of the meanings. They increase the number of dee notes when they are alarmed, give a gargling call, often aggressively, when a lower-ranking bird gets too close. And a high pitched see is a serious 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.”
Further studies in communication in birds may provide insights into the evolution of structural complexity of human language.
