Birds with big brains don’t shrink much, compared to birds with smaller brains.
in a Climate change Affect many organisms and the birds do not run. One study Published a week ago, it focused on birds’ adaptation to these climate changes. The research was conducted by experts from Washington University in St. Louis, USA.
Researchers analyzed the carcasses of tens of thousands of birds that died in Chicago, when they did not escape local skyscrapers in the process of their migration (between Canada and countries in Central and South America). We analyzed around 70 thousand birds who died in Chicago between 1978 and 2016.
Migratory birds in North America shrinkas a response to climate change. But this study shows that birds have The biggest mindsRegarding body size, They don’t shrink muchCompared to birds with smaller brains.
The analysis, published in the scientific journal Ecology Letters, specifically sought to understand and identify a The relationship between cognition and animal response to man-made climate change.
Justin Baldwin, a doctoral student at the University of Washington explained: “P Temperature rises, body size decreases. But species with larger brains regress less than species with smaller brains.”
Justin noted that many experts consider the relative size of the brain to be an indicator of behavioral flexibility in birds. This is size from the brain that it related to the ability to learnwith memory, with more stable life expectancy and population dynamics.
Therefore, a bird with a larger brain “may be able to reduce its exposure to higher temperatures, and seek out micro-habitats with lower temperatures, for example.”
However, it is not known why the bird population is declining. What is known that this Deflation can harm the birdIt is more vulnerable and easy to fall victim to a predator.
Carlos Botero, a professor at the University of Washington, added to CNN: “In this study, one of the first things that struck me is that we can actually see that Climate change is having a disproportionate impact in species that are least able to deal with environmental change through their behaviour.”
“This does not mean that climate change does not affect intelligent birds. What this suggests is that the Climate change could have a much stronger impact on less intelligent birdsBotero warned.
