Signals and Songs
Bird communication – through beautiful songs and extraordinary patterns of color – makes everything possible, from deterring predators and intimidating rivals to impressing potential mates. There's an owl that can expertly camouflage itself against the bark of a tree to avoid discovery, a bird family that raises the feathers on their heads as they greet each other, and a multi-vocal bird that can imitate sounds ranging from a the click of a camera shutter to the sound of a chainsaw. With their varied methods of survival and communication, these birds show how it takes a little creativity and at times quick thinking to overcome obstacles to the best of their ability.
