Click here for an older post called "Titmice and chickadees cache food for winter survival" to read more about this unique ability.

For an article from Lehigh University that explains how this works in a little more detail, click here. In the article, Colin Saldanha talks about how the bird's hippocampus expands by about 30% in autumn due to the creation of new nerve cells. In the spring, the chickadee's hippocampus returns to normal size.
