What traits do the prey animals shown here have in common that help them survive

Adaptation—the modification of an organism or its parts—is a basic principle of evolution. An adaptation is an inherited characteristic that helps an organism survive and reproduce in its environment. Birds show the same diversity of lifestyles as mammals, but they also show some unique adaptations

Camouflage, highly developed senses, warning signals, and different defensive weapons and behaviour's are all used by prey animals for survival.
