Birds Evolve Different Body Temperatures in Different Climates

During the northern hemisphere summer of 2022, yet another round of extreme heat waves roasted Eurasia, North America and northern Africa – a stark reminder that these conditions are becoming the new normal.

These events can have a devastating impact on wildlife. For instance, reports of large-scale deaths of birds have become regular in recent years, as we’ve seen in Patagonia, Argentina and Spain. These events underscore the need to understand the ability of birds (and other animals) to tolerate extreme heat. This information will be essential for predicting where and when future mortality events could occur. It can also tell us which species will be most affected.
