The one bird you will see almost every day at the Sanctuary is the Black-capped Chickadee. Ever wonder how such a tiny bird survives the cold winter? At birdnote.org they explain that:
“For winter survival, chickadees have three things going for them: they’re insulated, they’re active, and they have a good memory.
Thanks to a half-inch coat of insulating feathers, chickadees maintain their body temperature at 100° Fahrenheit during daylight hours, even when the air is at zero degrees. At night, their temperature drops 18 degrees, which reserves their store of fat.
Also, chickadees gather food at a terrific rate. In autumn, they stash their winter sustenance all around their territory. Their good memories enable them to find this food when the days are short and cold. It’s not surprising that the part of the brain associated with spatial memory is larger in chickadees than in many other birds.”
