First, the bad news: The U.S North American Bird Conservation Initiative just released its State of the Birds 2025 report, and the birds with the most dire losses continue to be grassland birds, a 43% decline since 1970.
Why do I want to go birdwatching at a landfill? Only because I want to see multiple kestrels, harriers, Bald Eagles, meadowlarks, sparrows (maybe some rare ones, if I’m lucky).
