Many Accipitridae and Strigiformes hunt and feed on house sparrows. These include Accipitridae, Falco columbarius, Nyctea scandiaca, Otus asio, and many others. Known predators of nesting young or eggs include Felis silvestris, Canis lupus familiaris, Procyon lotor, and many Squamata. House sparrows avoid predation by foraging in small flocks so that there are many eyes watching out for potential predators.
