Did you know?
Females make all the same vocalizations and calls as the males—except for one: Females do not sing the "true" song—the song that identifies a male on his territory.
People have always believed that singing birds are happy birds. It may be scientifically true! A study shows that birds have higher levels of endorphins (the all-natural, feel-good chemicals our bodies make) when they’re singing.
