Behavior
The American Goldfinch is gregarious during the non-breeding season, when it is often found in large flocks, usually with other finches. Flocks generally fly in an undulating pattern, creating a wave-shaped path. During the breeding season, it lives in loose colonies. While the nest is being constructed, the male will act aggressively toward other males who intrude into his territory, driving them away, and the female reacts in the same way toward other females. This aggressiveness fades once the eggs have been laid.
The American Goldfinch does not act aggressively toward predators within its territory; its only reaction is alarm calling. Predators include snakes, weasels, squirrels, and Blue Jays, which may destroy eggs or kill young, and hawks and cats, which pose a threat to both young and adults. As of 2007, the oldest known American Goldfinch was 10 years and 5 months old.

Famous quotes containing the word behavior:
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
“One never gets to know a person’s character better than by watching his behavior during decisive moments.... It is always only danger which forces the most deeply hidden strengths and abilities of a human being to come forth.”
—Stefan Zweig (18811942)
