In California, researchers have found that birds in San Francisco Bay have slowly been getting bigger over the last 27 to 40 years.
This is strange because as climates get warmer, animals tend to shrink in size over the years.
The theory is that larger animals conserve body heat better.
One of the researchers said:
"We had the good fortune to find an unexpected result—a gem in research science, but we were then left with the puzzle of figuring out what was going on."
Which we're sure must be fun for the scientists.
They came up with several reasons why this might have happened, from more fat stores because of increasingly common server weather events to changes in plants that could have altered the birds diet.
Regardless of the reason, scientists feel good about the result. One said:
"It gave me a little more hope that these birds are able to respond—hopefully in time—to changes in climate."
So the birds can survive climate change. We wonder how humans will fare.
