“There is the mammal way and there is the bird way.” But the bird way is much more than a unique pattern of brain wiring, and lately, scientists have taken a new look at bird behaviors they have, for years, dismissed as anomalies or mysteries –– What they are finding is upending the traditional view of how birds conduct their lives, how they communicate, forage, court, breed, survive. They are also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own: deception, manipulation, cheating, kidnapping, infanticide, but also ingenious communication between species, cooperation, collaboration, altruism, culture, and play.

Some of these extraordinary behaviors are biological conundrums that seem to push the edges of, well, birdness: a mother bird that kills her own infant sons, and another that selflessly tends to the young of other birds as if they were her own; a bird that collaborates in an extraordinary way with one species—ours—but parasitizes another in gruesome fashion; birds that give gifts and birds that steal; birds that dance or drum, that paint their creations or paint themselves; birds that build walls of sound to keep out intruders and birds that summon playmates with a special call—and may hold the secret to our own penchant for playfulness and the evolution of laughter.
