Intelligence
In a paper published in 2009, researchers found that mockingbirds were able to recall an individual human who, earlier in the study, had approached and threatened the mockingbirds' nest. Researchers had one participant stand near a mockingbird nest and touch it, while others avoided the nest. Later, the mockingbirds recognized the intruder and exhibited defensive behavior, while ignoring the other individuals.

Famous quotes containing the word intelligence:
“... perhaps there exists only one intelligence from which the world sublets, one intelligence toward which each person, from the depths of his individual body, directs his gaze, as in the theater where, though each has a seat, however, there is only one stage.... But if it we all shared the same intelligence, [Bergotte] would, upon hearing me express [my ideas], remember them, love them, smile at them....”
—Marcel Proust (1871–1922)
“A German immersed in any civilization different from his own loses a weight equivalent in volume to the amount of intelligence he displaces.”
—José Bergamín (1895–1983)
“Since an intelligence common to us all makes things known to us and formulates them in our minds, honorable actions are ascribed by us to virtue, and dishonorable actions to vice; and only a madman would conclude that these judgments are matters of opinion, and not fixed by nature.”
—Marcus Tullius Cicero (106–43 B.C.)
