People don't like hearing this, but outdoor cats are the largest source of human-caused bird deaths. They kill Billions of birds every year in the US, especially ground-nesting birds.
Nothing wrong with being skeptical. It's a meta-analysis, so it sources it's data from other papers. You would probably need to go through it's references to drill down into the data.

Is there a lore reason why Hawaii bird extinction peaked back then? Hawaii didn't become a state until 1959, so shouldn't it peak in the 60s?
