The results of these studies showed that birds dream, as it turned out … In pigeons, as in humans, during deep sleep the flow of cerebrospinal fluid increases. This helps the bird’s body get rid of the “garbage” that has accumulated during the day.
The most interesting thing happens during the fast rest phase. During this time, parts of the pigeon’s brain responsible for processing visual information and analyzing flight movements are activated.
At the same time, a bird’s eyeballs constrict as often as during courtship or aggression.
Based on the data obtained, the scientists concluded that the pigeons most likely fly in their sleep and experience this process emotionally. However, more research is needed to better understand what birds dream of.
