Behavior
These birds are permanent residents, but sometimes they move south within their range, and even outside of it, in the fall or winter.
During the fall migration and in winter, chickadees often flock together. Many other species of birds – including titmice, nuthatches, and warblers – can often be found foraging in these flocks. Mixed flocks stay together because the chickadees call out whenever they find a good source of food. This calling-out forms cohesion for the group, allowing the other birds to find food more efficiently. When flocking, Black-capped Chickadees soon establish a rigid social hierarchy. In such hierarchies, males usually rank over females, and older birds over juveniles.
Black-capped Chickadees sleep in thick vegetation or in cavities, usually singly, though there have been suggestions that they may occasionally roost clumped together. The sleeping posture is with the bill tucked under the scapular (shoulder) feathers.
This bird scratches its head with its foot over the wing. It can bathe in water, dew, or snow; Young chickadees have been observed dust-bathing.
Their flight is slightly undulating with rapid wing beats. Flight speed is about 20 km/h (12.5 mph).

Famous quotes containing the word behavior:
“Children can’t make their own rules and no child is happy without them. The great need of the young is for authority that protects them against the consequences of their own primitive passions and their lack of experience, that provides with guides for everyday behavior and that builds some solid ground they can stand on for the future.”
—Leontine Young (20th century)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
