This study, which was published in 2021 in the Journal of Ornithology showed that the two parts of the brain that make up an ostrich’s brain are different than those of other animals. Not only did the scientists conclude that ostriches have bigger brains than some other land animals, but they also determined that the specific organ that makes up the brains of ostriches is different from the one that makes up the brains of other animals. What the study showed was that ostriches, which are primarily arboreal birds, do in fact have brains that are significantly larger than those of some land animals such as mice. Luckily for them, they came up with an ingenious study that involved using billiard balls. In order to measure the brain size of different types of birds, scientists needed a way to determine which bird has a brain smaller than either of its eyeballs. So the next time you look at your favorite animal and ask what animal has a brain smaller than either of its eyeballs, you might want to know the answer.
To put it in simple terms, ostriches have bigger brains. The result of this study was published in 2021 in the Journal of Ornithology. Scientists have actually been able to measure the brain sizes of several different types of birds and they were able to determine that they did indeed differ. Of course, whether ostriches laid eggs or played with the holes in the earth, the question of the obvious question which bird has a brain smaller than either of its eyeballs still remains. Another theory is that the holes were made by prey animals as they tried to escape from predators. One theory is that the holes were made by the long-necked dinosaur that walked the earth and ate the vegetation around it. In order for this to be true, the eggs would have been buried in layers of earth that would eventually have to be recovered and interpreted. The eggs laid by ostriches must have contained more food than was visible to the eyes of the female when she was roaming the jungle. This is where the ideas of primitive nests and the importance of food storage came into play. Even though it is not clear exactly where the idea of an egg-laying organ originated, most palaeontologists believe it dates back to the time when dinosaurs started using nest boxes as their homes. For instance, it is known that dinosaurs had brains, but they were much different from the size and shape of modern birds. Although there is a lot of disagreement among palaeontologists as to the exact characteristics of the brain and how it evolved, a lot of what we do know is based on indirect evidence from fossils. If you have ever noticed that ostriches and parrots look a lot like smaller versions of their relatives such as chickens and ducks, then you are not alone in assuming that these creatures have brains similar to those of other animals. It’s amazing how little we really understand about some of the most basic features of birds.
