The article, SOCIAL OR STINKY? NEW STUDY REVEALS HOW ANIMAL DEFENSES EVOLVE, by the University of California – Davis is about how animals defend themselves against carnivorous animals. The researchers found out that animals that are active in the night and under threat form others use “noxious spraying,” while those are active during the day and fear from from “birds of prey….live in social groups” to defend themselves against predators.
“Noxious scents” is most effect at night when vulnerable animals unexpectedly find out predators near them. At night, they may even “stumble upon a predator.”

On the other hand, social animals live and stay in groups during the day to protect themselves. This means “more eyes on the sky.”
In addition to this, social animals use other defense techniques like “calling out a warning” to their peers and “mobbing together to bite and scratch” threats.
