Animals that I would rate as being probably above bear intelligence are:
1 - Corvus birds ( crows, ravens, etc ).
2 - Whales and dolphins.
3 - humans ( with exceptions ).

Great research Brobear. I liked how you put crows on the list. People don't relaize how smart crows actually are.

Hey brobear, sorry for not being able to merge topics on time (had 2 finals to study for and a HARD final project), but now I am free of school responsibilities!
My list goes like this, and each number rank might be multifaceted with multiple animals
1. Humans/dolphins/apes and primates/bears
2. Elephants/felines/corvids (maybe)
3. Pigs
4. Canines
and etc...
But still. intelligence is nearly impossible to quantify; it has many types and even those types are hard to quantify.

www.iflscience.com/plants-and-animals/crow-brains-reveal-secrets-their-intelligence/ Crow Brains Reveal Secrets of Their Intelligence. Crows are well known for their intelligence. In fact, the entire Corvidae family is renowned for being the smartest of all birds and some of the smartest of all animals. The secret to their superior intellect has been located in their brain for the first time, according to a new study from Lena Veit and Andreas Nieder from the Institute of Neurobiology at the University of Tübingen. The paper was published in Nature Communications. Corvids like crows and ravens have been known for their intelligence long before much research was given to the subject. In addition to being one of the few animals capable of using tools to find food and solve problems, they have complex social structures. Information is shared within the murder so that group decisions can be made. They have incredible memories which allow them to recognize human faces. This is bad news for the people that aren’t well liked by the birds, because word can spread and the crows will dive and attack faces. Unfortunately, because bird brains are so different from mammalian brains, not a lot has been known about how decisions are made and where avian intelligence actually comes from. For the study, the crows were trained to perform a series computerized memory tests. An image would flash on the screen and then disappear. Next, two more images would appear. One was the same as the first while the other was different. Some portions of the test required the crows to find a match with the first image and other sections wanted the image that was different. After a brief training period the crows were able to do the test effortlessly, even when unfamiliar images were used. While the crows were busy selecting images, researchers were mapping the birds’ neurological function. They discovered that there was a great deal of activity in the nidopallium caudolaterale, which is somewhat analogous to the human prefrontal cortex. This is the region of the brain where higher-thinking occurs and executive decisions are made. The researchers also noticed activity in different areas based on if the crow was supposed to pick the item that was the same while a different area was used when the selected image was supposed to be different. After a while, the researchers could use the bird’s brain activity and see what it was going to select before the bird had a chance to submit its choice. Because bird brains are so different from mammalian brains, there aren’t a lot of shared structures from before the divergence over 300 million years ago. Even though the structure isn’t the same, there are a lot of similarities in the decision-making cells. The researchers speculate that the intelligence seen in mammals (primates, specifically) and that found in birds could very well be a product of convergent evolution.

www.elephantsforever.co.za/elephant-intelligence.html Elephants continue to fascinate both scientists and general observers alike. They are recognised as being among the most intelligent creatures on earth. In fact, some enthusiasts believe that their intelligence rivals that of human beings. Aristotle even said of elephants: "The beast which passeth all others in wit and mind". Proportionally, the elephant's brain is the most sizeable at a mass of just over 5kg. Although the largest whale is 20 times the body size of an elephant, its brain is just under twice the size. The need for such a large and complex organ becomes clear when we consider the behaviours and abilities of these animals. Elephants are capable of a range of emotions, including joy, playfulness, grief and mourning. In addition, elephants are able to learn new facts and behaviours, mimic sounds that they hear, self-medicate, play with a sense of humour, perform artistic activities, use tools and display compassion and self-awareness. Part of the reason that elephants possess such a superior level of intelligence is the structure of their brain. Their neocortex is highly convoluted, as it is in humans, apes and some dolphins. This is generally accepted to be an indication of complex intelligence. The cortex is thick and comprises many neurons. The elephant is one of the few creatures (along with human beings) that is not born with survival instincts, but needs to learn these during infancy and adolescence. The brain is specially designed to accomplish this sort of life learning. Elephants and humans have a similar lifespan, and plenty of time, approximately 10 years, is allowed for them to learn before they are considered to be independent adults. The lessons learnt include how to feed, use tools and understand their place in their social structure. Elephants capacity for memory and emotions is remarkable and is due to the well-developed hippocampus. This is also the area responsible for emotional flashbacks and is the reason that elephants experience Post-Traumatic Stress Disorder. The insight and intelligence of the elephant is particularly note-worthy in their ability to mourn their dead. This behaviour has only previously been noted in humans. In fact, recently deceased elephants will receive a burial ceremony, while those who are already reduced to a skeleton are still paid respect by passing herds. The burial ceremony is marked by deep rumblings while the dead body is touched and caressed by the herd members trunks. Intelligence is also manifested in the elephant's ability to self-medicate. When a pregnant mother is due to give birth, she will chew on the leaves of the tree from the Boraginaceae family to induce labour. Another ability that indicates superior intellect is elephants ability to play and display a sense of humour. Games include throwing a stick at a certain object, passing an object from one animal to another, or squirting water out of the trunk in a fountain. Elephants in zoos have even been seen stealing onlookers caps and hiding them in playful teasing. The ability to mimic sounds is another indication of the impressive intelligence of these beasts. Elephants have been recorded mimicking passing trucks and even the sounds made by their trainers. Often, the elephant manages to articulate certain sounds so that they bear a strong resemblance to the spoken word. Elephants are able to use tools or implements to accomplish a task they cannot perform on their own. They have been observed digging holes for drinking water, then moulding bark from a tree into the shape of a ball and placing it on top of the hole and covering it over with sand to avoid evaporation. They also use sticks to scratch their backs when their trunk can not reach and have been known to drop rocks on electric fences to damage them. The elephant's problem solving abilities are another impressive facet of their boundless intelligence. Incredibly, the elephant is able to change its behaviour based on a given situation. Bandula, an Asian elephant in captivity, had learnt how to release the complex hook on her shackles and would then assist her fellow "inmates" to escape from theirs. Self awareness is yet another indication of the vast capacity for thinking and intellect that exists in the elephant. They can, in fact, recognise themselves in a mirror, something that is extremely rare in the animal kingdom. These capabilities are merely touching the tip of the iceberg of what is the elephant's capacity for insight, thought and discernment. And it is this capacity that continues to captivate researchers and onlookers alike in their eternal quest to understand the mystery of the elephant psyche.

These animals listed are the only animals I would place above bears - not written in any particular order. Equally with bears are ( IMO ) elephants and the great apes.  |

Remember Big Cat Diary - en.wikipedia.org/wiki/Big_Cat_Diary There was this one episode that I can not forget. The day was exceptionally hot. There was a lone male African lion. There were two carcasses, neither one really large ( antelopes ). There was a fairly large distance between the carcasses, but the lion wanted them both. His problem, jackals. The lion just ran from carcass to carcass trying to keep the jackals away from them. Not far behind both carcasses were some trees and shade. The man, a park ranger, stated outright that "lions are not known to be smart animals." The lion could have carried both carcasses into the shade to eat comfortably and peacefully. But instead he exhausted himself out in the hot sunshine running from carcass to carcass. |

The intelligence of crows are truly underrated. |

Measuring intelligence is not simple. Can't be measured by a measuring tape or in a measuring cup. Simply from my own observation of cats, I don't see them ( as a whole ) being particularly smart animals. But then, I'm not trained in any field of biology either.

I also heard that lions are smarter than tigers because they are more social. I definitely place dogs above cats. Also, the wolf is smarter than his domesticated descendants. Edit and add: I watched a documentary on wolves once which made the statement that while lions in Africa are successful group hunters, the hunting strategies of wolves are often far more complex. |

Heck yeah I place wolves above big cats too. In fact I think the wolf is the number 2 smartest land predator under the bear. I think the bear is number 1 as smartest predators.

news.nationalgeographic.com/2017/11/dog-cat-brains-neurons-intelligence-study-spd/ Are Dogs Smarter Than Cats? Science Has an Answer A team of researchers counted the number of neurons in dog and cat brains and found one had twice as many as the other. Dogs, it turns out, have about twice the number of neurons in their cerebral cortexes than what cats have, which suggests they could be about twice as intelligent. This finding was provisionally accepted for publication and will soon publish in the journal Frontiers in Neuroanatomy. A team of researchers from six different universities in the U.S., Brazil, Denmark, and South Africa contributed to the research. One of the study's authors is noted neurologist Suzana Herculano-Houzel. For the past decade, the now Vanderbilt professor has been studying cognitive function in humans and animals. To get as precise a measurement as possible, she starts by counting neurons, a special type of nerve cell found in the brain that transmits messages. "You take the brain and turn it into a soup," she said, matter-of-factly, as the first step to finding these neurons. From there, she said, you end up with a number of suspended nuclei from neuron cells that allow the researchers to estimate the number of neurons present. Why Use Neurons? "Neurons are the basic information processing units," said Herculano-Houzel. "The more units you find in the brain, the more cognitively capable the animal is."

www.pnas.org/content/113/9/2532 Results: We tested one to nine individuals in each of 39 species (mean = 4.9 individuals; median = 5) (Table S1). Of 140 individuals tested, 49 individuals (35%) from 23 species succeeded at opening the puzzle box (Fig. 1A, Table S1, and Movie S1). The proportion of individuals within each species that succeeded at opening the box varied considerably among families, with species in the families Ursidae (69.2% of trials), Procyonidae (53.8% of trials), and Mustelidae (47.1% of trials) being most successful at opening the puzzle box and those within the family Herpestidae (0%) being the least successful (Table S1). Total brain volume corrected for body mass varied among the species that we tested, with Canid and Ursid species having the largest brains for their body mass and Viverrid, Hyaenid, and Herpestid species having the smallest brains for their body mass (Fig. 1B and Table S1)

CATs are not smart animals. How often have I stepped on a cat because they can-not figure out that when a person is busy doing something ( example - hanging out laundry ) that persons feet are in constant motion. If the cat is stepped on a half-dozen times, it still stays underfoot. They just don't learn. Here, my daughter has cats. She started with one, which is fed in the open front porch. We are now feeding an untold number of cats. The same cats are forever coming inside when the door is opened. There is nothing for them in the house. Once inside, they want out. But, you put the cat out, next time you open the door, here he comes back in, just to want out again.
There remains no slightest doubt in my mind that dogs are much smarter than cats. There also is no lingering doubts that bears are much smarter than dogs. What dog would ever conceive of the idea to back-track, carefully placing each foot into another footprint, while walking backwards, so as to fool someone following him? What dog might conceive of the idea of placing his feet upon logs, stumps, etc. where there is no snow, to hide his tracks by not making any? The bear is probably the only animal other than a human to ever do this.

I lived with a white cat with green eyes named Marika, she does not like being touched by strangers but she has learned to respect me. Have to be careful as she gets in your way at times. |

We all here know that bears are smarter than big cats. I put the tiger above the ion when it comes to smarts. I remember watching a animal experts say out his own mouth that tigers are smarter than lions. Seem like lions are pretty dumb.
