Many birds are already in dramatic decline from threats like forest fragmentation, southern deforestation, windmills, and cellphone towers. I doubt they’ll be able to kill off black birds and seagulls, though.

In New Zealand, The Seagull has become an endangered species, even though there are lot of them. "Because it's a species that's quite long-lived it can take 100 years before you see a significant change in the numbers. As long as the adults aren't being killed, it will be a long, slow decline. Seagulls can live up to 30 years."
Per tower or in total? I don’t understand how a spinning turbine is safer than a tower, so if you’re talking about it in total then how many extra bird lives will be lost when the number of wind turbines increase drastically?
The theory goes that, as birds have excellent eyesight and use it to navigate, they're more likely to avoid a huge slowly rotating object than a very narrow pointy one.
Sadly, I think it’s a variety of factors pecking away at them from all directions, so to speak. Habitat loss, loss of food stocks, urban, suburban, agricultural and industrial pollution, more buildings to fly into, intentional killing, pets, climate change, and probably even more. Essentially being a bird isn’t working out for them right now.
They fly into it and die since giant metal structures are not found in nature. Makes sense, right? Tens of thousands of birds can die in one night on one tower during migrations.
