On the other hand, I've read that birds (and rodents) have thrived because of humans. We've killed off or limited the range of their predators. Many birds do well in cities, and unlike ground animals, they aren't stymied by all our roads and highways.
So while the number of species of birds is likely much smaller, in terms of absolute population there might even be in increase.
This is nothing to be proud of though. We might be to the planet what the coronavirus is to humans.
