Bird populations in the United States and Canada have dropped by 29% since 1970, signifying 2.9 billion birds lost in almost 50 years, according to a new study.The scientists involved in the study warn that like a canary in a coalmine, birds reveal environmental health. This steep loss of bird populations, including some of the most common birds like sparrows and finches, shows that human impacts on the continent's environment mean it can no longer support the wildlife systems it once did.Normally, it's hard to track animal populations this way. But birds are much easier to monitor. The study combines almost 50 years of data, including information collected by citizen scientists and weather radar data of migratory birds from 143 stations across North America. Observations by people were shared with the North American Breeding Bird Survey at the US Geological Survey, the Canadian Wildlife Service, the Audubon Christmas Bird Count and Manomet's International Shorebird Survey."Citizen-science participants contributed critical scientific data to show the international scale of losses of birds," said John Sauer, study co-author at the US Geological Survey. "Our results also provide insights into actions we can take to reverse the declines."The study was published Thursday in the journal 1315

A Black city, with a Black mayor (who marched with us), and many Black owned businesses. 100% peaceful demonstrations.

California will be the first state to require public colleges and universities to offer abortion medication at campus health centers. The new legislation was signed into law by Governor Gavin Newsom.
