Crows can identify themselves in mirrors, use tools, and prepare for the future, all of which are mental abilities found in humans and other mammals but not most other birds.
This ability might be linked to the fact that they have a colossal number of brain cells involved in the processing of information.
Felix Ströckens and colleagues from Germany's Ruhr University Bochum examined the brains of common ostriches (Struthio camelus), brown warren fowl (Gallus gallus domesticus), racing homer pigeons (Columba livia domestica), and three members of the human species.

Crows and ravens are well-known for their dark coloration and noisy "caw" sound.
They are sophisticated birds who utilize tools to solve complicated abstract issues and communicate a lot.
Their richness is paralleled by their ability to live in a variety of environments across the world.
They are, in fact, one of the most common families of birds on the globe.
Crows and ravens, which are members of the bird family Corvidae, which also includes jays and magpies, have seen fast worldwide expansion, in contrast to other members of the family, which have remained primarily within single continents.
While their flying abilities were critical to their survival, according to research from Washington University in St. Louis, large bodies and big minds also played a part in crows and ravens surviving in the new climates they inhabited.
When they think about processes of global diversification, it is crucial to examine not only the ability to reach new places but also the ability to withstand once there, said Carlos Botero, assistant professor of biology at Arts & Sciences.
According to the findings, crows and ravens differentiated quickly and extensively because they were particularly adept in adapting to numerous environments, as cited by ScienceDaily.
The neocortex is a compound found in the brains of sentient animals such as humans. This is meant to help with the analysis of detailed cognition.
Corvids, for example, lack this framework. Instead, they have evolved tightly packed clusters of neurons that provide them with equivalent mental capacity, according to BBC Future.
In the study led by Joan Garcia-Porta, a colleague in the Department of Genetics at the University of Barcelona, the authors demonstrated that crows' and ravens' incredible ability to hugely grow and expand from around the planet was influenced by a specific variety of symptoms.
Using specimens from museums in Europe and the United States, the researchers discovered that they have longer wing lengths, larger body sizes, and larger relative brain sizes than other Corvids.
Some animals may appear to be smarter than others, with humans at the top of the metaphorical food chain.
To be sure, people rely far too heavily on intelligence to get through. However, this does not imply that we are the greatest at every mental endeavor.
According to Dakota McCoy of Harvard University, chimps have stronger short-term memory than humans.
While intellect may assist a species in doing things necessary for life in its own habitat, other creatures survive in different ways.
