Even the most geographically remote species can't avoid the climate crisis.
Some animals are adapting to the climate crisis in a very visible way: they’re altering the shape of their bodies.

Bigger ears, longer tails, and lengthier legs can make it easier for different species to regulate their body temperatures when the heat spikes.
A study published November 12 in the journal Science Advances documents the altered bodies of birds living in the Amazon rainforest over the course of 40 years.

The Amazon has become significantly hotter and drier. These changes are largely attributed to human activity.
“These birds don’t vary that much in size. They are fairly fine-tuned, so when everyone in the population is a couple of grams smaller, it’s significant.”
Shrinking birds have been observed elsewhere, too.
The researchers say that further analysis may uncover similar trends across the globe.
