> Grassland species have suffered the biggest declines by far, having lost 717 million birds. These birds have probably been decimated by modern agriculture and development.
This has been known for a while. I remember hearing a piece on NPR about this maybe a decade ago. The problem is actually that we have been working hard to reforest, and haven't left grassland. Everything is either forest, or developed, with very little in-between. One of the proposed solutions was to simply not mow 100% of your yard. Leave some bit of it unkempt. There's a local monastery that does this, and there are birds there that I haven't seen anywhere else in the area, so I think there's something to the strategy.
