Birds of prey rarely attack house sparrows because of where they primarily hang out, mostly in public or residential areas. But it's not just animal predators. Nature has a way of keeping the population of a species in check, whether by predators, disease, climate, habitat, and other environmental factors. When you introduce a species into a new environment, sometimes (not always) it isn't subject to the same stresses and is able to propagate without bound, like house sparrows.
