Scientists are studying mountain chickadees in the Sierra Nevada for their doctoral research.
They say they use complex calls to communicate with each other and communicate a variety of information.
Scientists say calls are arguably the most important type of vocalization, at least for highly social bird species.
Calling is similar to how humans learn how to speak from adults.
The "chick-a-dee" call of the mountain chickadee contains six elements, known as notes or syllables, that can be combined in hundreds of unique combinations to say many different things.
Scientists don't fully know the meaning of each note in different contexts, it is generally believed that A notes typically contain identifying information about how important the topic seems to the caller.
