Black-capped Chickadee 12/23/17

Cheerful and curious, Black-capped Chickadees have developed numerous adaptations for surviving the frigid temps of winter. They become omnivorous, they cache food, they can lower their body temps at night, and they have several roosting cavities to choose from when it’s time for bed or whenever they need a cozy spot to ride out a spell of dirty weather. Roost cavities are much smaller than nest cavities, most commonly they are small cracks or holes in trees (esp. birches), and need only be large enough and sheltered enough to keep out wind and precipitation.
