Climate （氣候） change is influencing animals in a lot of different ways.Scientists have noticed a common trend （趨勢(shì)） across all kinds of animals：they're getting smaller — physically smaller in size.
    Scientists have studied many different animal species from wild sheep to woodrats over the past 40 years.But they paid more attention to the North American songbirds.In 2019，researchers at the University of Michigan published a set of data （數(shù)據(jù)），which showed that the body sizes for quite a few species had actually shrunk （縮小）.
    But when Justin Baldwin，a graduate student at Washington University took a closer look at the data and he noticed something different.Birds with larger brains are shrinking at slower rates （比率） than birds with smaller brains.
    Baldwin and his team had a feeling that birds' behavior might be playing a role. "In birds，species with bigger brains seem to be smarter and can change their behavior based on their environment.That means that they might be able to protect themselves from increasing temperatures.Bigger-brained birds，for example，might adjust （調(diào)整） their behavior and stay in the shade when it's hot，" says Carlos Botero，an assistant professor.
    Baldwin's team found it was still true even after controlling other factors like generation time and mutation （變異） rate.But Botero also says， "Though these bigger-brained bird species can temporarily （臨時(shí)地） protect themselves from warmer temperatures，it doesn't mean they are able to fit in with any kind of change forever."
