This is an example is spatial learning behavior used to navigate. Dung beetles orient themselves in relation to star patterns and light polarization to remain moving their balls in a straight line.
This is an example of fixed action pattern behavior to avoid danger. If a cat encounters an unexpected long, green object, it will leap and escape the area. An expert speculates this is designed to avoid snakes.
This is an example of mating behavior (sexual selection) to raise the chances of reproducing. Bulls will compete with one another by clashing antlers in an attempt to raise their "ranking" of strength among females. This is a desirable trait and increases the likelihood of them mating.
This is an example of communication behavior through sound and vibration. In the event of danger, an elephant will produce a higher-frequency sound and a lower-frequency vibration that is picked up by others who then evacuate.
