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:
“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
—William James (1842–1910)
“Gaining a better understanding of how children’s minds work at different ages will allow you to make more sense of their behaviors. With this understanding come decreased stress and increased pleasure from being a parent. It lessens the frustrations that come from expecting things that a child simply cannot do or from incorrectly interpreting a child’s behavior in adult terms.”
—Lawrence Kutner (20th century)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
