Chickens are inquisitive, interesting animals who are thought to be as intelligent as cats, dogs, and even some primates. They understand sophisticated intellectual concepts, learn from watching each other, and even have cultural knowledge that is passed from generation to generation. Dr. Chris Evans, a scientist who studies avian cognition says, “As a trick at conferences I sometimes list these attributes, without mentioning chickens, and people think I’m talking about monkeys.” Read more.
Pigs
Pigs are curious and insightful animals thought to have intelligence beyond that of an average 3-year-old human child. They are smarter than dogs and every bit as friendly, loyal, and affectionate. Scientists and scholars who have studied pigs say that pigs are the smartest animals outside of primates. Says Dr. Donald Broom, scientific advisor to the British government, “[Pigs] have the cognitive ability to be quite sophisticated. Even more so than dogs and certainly three-year-olds.” Read more.
Cows
Cows are intelligent, loyal animals who enjoy solving problems. Cows have been known to use their smarts to perform amazing feats, such as leaping over a 6-foot fence to escape a slaughterhouse, walking 7 miles to be reunited with a calf after being sold at auction, and swimming across a river to freedom. When cows figure out the solution to a problem, they have a “Eureka!” moment, according to animal behaviorists. Read more.
Fish
Fish are smart, sensitive animals with their own unique personalities. They have excellent memories and can learn to avoid nets by watching other fish in their group and can recognize individual “shoal mates.” Some fish gather information by eavesdropping on others, and some even use tools. Says marine biologist Dr. Sylvia Earle, “They’re so good-natured, so curious. You know, fish are sensitive, they have personalities, they hurt when they're wounded.” Read more.
