Going to public school in Wisconsin, I remember being taught about fragmentation and how it let brood parasites like cowbirds have better access to the nests they sneak their eggs into, which leads to the death of lots of chicks from other species. Wisconsin still has lots of forest, but with so many roads and fields cutting through them, they just can't support the same level of wildlife.
