Animals can be pretty smart sometimes. That’s common knowledge to anyone who owns a dog, or even a cat. But everyone’s favorite pets aren’t actually the brightest ones in the animal kingdom. They’re actually kind of dumb in some ways when compared to creatures like the elephant, pig, or even octopus. There’s also another group of animals that can be surprisingly intelligent – birds. While most of them are famously feather-brained, there are some species out there who display almost human-like intelligence. Case in point, a recent study found that corvids – that is ravens, crows, and others like them – possess the ability to analyze their own knowledge, something we’ve thought only humans are capable of. Maybe we’ll cover that in a future story.
