Behavior
Like all swifts, the Chimney Swift is incapable of perching; instead, it clings to vertical surfaces.
The full population migrates seasonally in large flocks, but in mild winters some may overwinter in Florida. This species has occurred as a very rare vagrant to western Europe, Great Britain or Pribilof Island, Alaska.

Famous quotes containing the word behavior:
“The civilizing process has increased the distance between behavior and the impulse life of the animal body.”
—Shoshana Zuboff (b. 1951)
“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)
“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)
