Scientists make worrying discovery after studying bird behavior across North America: ‘They can’t move fast enough’

By Jenny Allison – The Cool Down

A new study from Yale University that tracked the movements of 406 species of North American birds revealed a troubling pattern: Even the fastest birds can’t outfly the dangers of the warming planet.

The study was published in the journal Nature Ecology and Evolution, and it tracked the movements of these species over two decades alongside corresponding temperature changes in their regions. 

Even when birds relocated to cooler areas in response to rising temperatures, researchers found, they couldn’t escape the heat.
