Out here we normally see three types of chickadees, boreal, mountain and the one in the picture, the Black-capped Chickadees. We see them year around, even during the cold Rockies winters. How can this tiny 10 gram birds survive during a period when many of us humans complain. They start getting ready during the fall, storing much of the seeds they come across in various locations, to come back to during the cold winter days. To remember all these location, their brains grow when it's time to store food, increasing the volume by as much as 30% and when the winter comes to a close, their brains shrink. These birds are more than just a pretty little things.
