Chickadee language

I just learned that the chickadee’s call is modified to convey key information – in ways that humans can understand, too! It turns out “chick-a-dee” is their alarm call, and the number of “dee”s tacked on to the end of the call conveys the magnitude of danger. I’ll definitely have to listen for this the next time I get to hear them!

I knew this already. I learned something new!
