What birds were a genuine threat to early humans? As far as I know, birds have mostly been more of a nuisance (carrion birds) or prey.

Havent read that book, but there has been several species of very large birds living during our time: https://en.wikipedia.org/wiki/List_of_largest_birds#Largest_...

I can imagine a 2m tall bird of prey would be a frightening thing to an early human.
