Cats and dogs can solve relatively complex problems, but they can't make and use tools. In this respect, you could say a crow is smarter that Fido and Fluffy. If your pet is a parrot, its intelligence is as sophisticated as a crow's. Yet, intelligence is complicated and difficult to measure.
Results showed that the dogs, having larger brains to begin with, had more than twice as many neurons in their cerebral cortex as the domestic cat, with around 530 million cortical neurons to the cat's 250 million. (For comparison, there are billions of neurons in the human brain.)
Crows are some of the smartest creatures in the animal kingdom. They are capable of making rule-guided decisions and of creating and using tools. They also appear to show an innate sense of what numbers are.
A crow is supposedly as smart as a 7-year-old. Here's how scientists figured that—and other facts—out.
The total number of neurons in crows (about 1.5 billion) is about the same as in some monkey species. But because they are more tightly packed, communication between the neurons seems to be better, and the overall intelligence of crows may be closer to that of Great Apes such as the gorilla.
The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8. The largest brains in the family Felidae are those of the tigers in Java and Bali. It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates.
Corvids are highly social, curious (exploratory) and opportunistic, with exceptional long-term memory. They are renowned for their problem-solving ability in the lab and in the field.
In the human brain, the cerebral cortex contains around 21 - 26 billion neurons, while a cat's cerebral cortex has about 300 million neurons. Experts believe that a feline's intelligence is comparable to that of a 2-year-old human.
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
The American Crow, however, is just the smartest in a whole family of whip-smart birds. They're in the family Corvidae, which consists of ravens, rooks, jays, nutcrackers, magpies, jackdaws, choughs, and treepies.
Crows are the smartest birds in the United States, with an intelligence level that may even be comparable to that of humans. In fact, some research has shown them to be smarter than some apes and only a little bit less intelligent than humans.
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.
Cats have an incredible ability to remain calm and display signs of empathy and cognition. As a display of intelligence, a cat going to space is almost hard to believe - sure, many dogs and chimps have been to space over the years, but taking an animal as brilliant as a cat is quite the feat!
Many feline behaviorists as well as child psychologists seem to agree that the intelligence of an adult cat equals that of a 2 to 3 year old child.
The Australian magpie is one of the cleverest birds on earth. It has a beautiful song of extraordinary complexity. It can recognize and remember up to 30 different human faces. But Australians know magpies best for their penchant for mischief.
The five native species of Corvids (crows and ravens) in Australia are the Australian Raven, Little Raven, Little Crow, Forest Raven, and the Torresian Crow. They are all quite similar – ravens being perhaps slightly larger – and some can be difficult to tell apart in the field without close scrutiny.
Magpies have shown the ability to make and use tools, imitate human speech, grieve, play games, and work in teams.
They can remember a person's face for up to 10 years! And kitties become seriously attached to their humans, so in case you were wondering, yes, your cat remembers and misses you when you're gone for a few weeks, and they absolutely mourn when a trusted companion drops out of their life.
With repeated introductions, cats come to know that it is themselves in the mirror, but the capacity of immediate self-recognition does not seem to be innate in the feline species. This capacity, however, does seem to exist in at least three species of more evolved mammals: bonobo chimpanzees, elephants and dolphins.
Studies on dog cognition do not support the idea that dogs view humans as bigger dogs, for example, and it's likely cats behave similarly, Griggs says. Rather, cats view us as social companions and a “valuable resource” — i.e. as a provider of food.
7. African Gray Parrots. African Gray Parrots are thought to be one of the most intelligent species on the planet, rivaling even apes. Some researchers have suggested that these parrots have a reasoning ability akin to a three- or four-year-old human child.
Chimpanzees. Chimps are our closest relatives in the animal kingdom, so it's unsurprising they display intelligence similar to that of humans. Chimps fashion spears and other tools, display a wide range of emotions, and recognize themselves in a mirror. Chimps can learn sign language to communicate with humans.
The experiments showed that the human and chimpanzee brain organoids were remarkably similar in many ways including in the mix of cell types and in how these cells were arranged.
