Summary: Bird species that spend more energy on their young have larger brains than those with less parental care.
Abstract: Big brains are useful, but they need time and energy to grow. So why do some animals have big brains and others don’t? We looked at 1,176 bird species to see how different things affect brain size. We found that parental provision had the largest impact on brain size. This includes egg size and caring for and feeding babies. We think parental care allowed larger brains to evolve. And not just among birds! This could also explain why human brains are so big!
