Maturational Instincts
Some instinctive behaviors depend on maturational processes to appear. For instance, we commonly refer to birds "learning" to fly. However, young birds have been experimentally reared in devices that prevent them from moving their wings until they reached the age at which their cohorts were flying. These birds flew immediately and normally when released, showing that their improvement resulted from neuromuscular maturation and not true learning.

Famous quotes containing the word instincts:
“When the excessively shy force themselves to be forward, they are frequently surprisingly unsubtle and overdirect and even rude: they have entered an extreme region beyond their normal personality, an area of social crime where gradations don’t count; unavailable to them are the instincts and taboos that booming extroverts, who know the territory of self-advancement far better, can rely on.”
—Nicholson Baker (b. 1957)
