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:
“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)
“To be told that our child’s behavior is “normal” offers little solace when our feelings are badly hurt, or when we worry that his actions are harmful at the moment or may be injurious to his future. It does not help me as a parent nor lessen my worries when my child drives carelessly, even dangerously, if I am told that this is “normal” behavior for children of his age. I’d much prefer him to deviate from the norm and be a cautious driver!”
—Bruno Bettelheim (20th century)
“In abnormal times like our own, when institutions are changing rapidly in several directions at once and the traditional framework of society has broken down, it becomes more and more difficult to measure any type of behavior against any other.”
—John Dos Passos (1896–1970)
