Grassland birds are disappearing even from areas designed to protect them
Even in protected areas, birds are disappearing from America's prairies, and unpredictable weather isn't helping. That's the takeaway from a new study by researchers at Michigan State University, Oklahoma State University and the Minnesota Department of Natural Resources.

Even within protected areas designed to safeguard them, grassland bird populations in America's tallgrass prairies are dwindling, according to a new study led by researchers at Michigan State University, Oklahoma State University, and the Minnesota Department of Natural Resources. Analyzing 16 years of bird survey data from 40 protected sites in western Minnesota, the study reveals a concerning 22% drop in the likelihood of spotting 33 monitored bird species over a 16-year period.
Despite the presence of habitat tailored for these birds, the long-term whistle of the upland sandpiper and the tuxedo-like plumage of the bobolink have faded, while the once-common birds now appear less frequent. The researchers found that even generalist species like mourning doves and red-winged blackbirds are less common today than they were 15 to 20 years ago.
While climate factors may play a role in some species' decline, the overall pattern remains consistent – grassland birds continue to disappear from these supposed strongholds, regardless of habitat size or quality. This suggests that conservation efforts alone may not be enough, particularly as climate change continues to alter conditions.
