I love the little Black-capped chickadee. Such a tiny bird, and so busy, they don't stay still for very long. And they are smart little cookies too!

Some Cool Facts about the Black-capped Chickadee from "All About Birds" https://www.allaboutbirds.org/guide/Black-capped_Chickadee/lifehistory):

"•Every autumn Black-capped Chickadees allow brain neurons containing old information to die, replacing them with new neurons so they can adapt to changes in their social flocks and environment even with their tiny brains."
"•Chickadee calls are complex and language-like, communicating information on identity and recognition of other flocks as well as predator alarms and contact calls. The more dee notes in a chickadee-dee-dee call, the higher the threat level."

The complexities of nature are amazing! We really should contemplate the wisdom shown there! I would like to be able to do this with my brain every autumn. I would be due for some changes now! :)
