"summary",
"A new study published in the journal Science analyzed nearly 500 bird species across North America and found that three-quarters are declining across their ranges. The study used citizen science data from eBird to model changes between 2007 and 2021, revealing dramatic declines in areas where birds were previously thriving. The researchers found that former strongholds for bird species are no longer safe, particularly in grasslands, drylands, and the Arctic. The study suggests that global heating and habitat change may be contributing factors, but the exact reasons are still unknown."
