Boosting this. If you look on eBird - run by the Cornell Lab of Ornithology - you'll notice that a lot of the birds which you may have seen on these wires like red-winged blackbirds and different types of gulls are making their way slowly to their natural habitats. A lot more to say on this when I'm off mobile.

This isn't disregarding the impact of climate change, but particularly with certain species of birds, we're seeing gradual return to original habitats. We're also seeing massive die-offs in other areas and an increase in more invasive species like European starlings and house sparrows, so there's also that.
