Can nonhuman animals drive other animals to extinction?

Imagine looking up at a sky so full of birds, they block out light from the sun. Passenger pigeons (Ectopistes migratorius) used to fly in flocks of hundreds of millions, maybe even billions, of birds that took hours to pass overhead. Then, we started shooting them.

Humans began commercially hunting passenger pigeons in the 19th century, and by 1914, they were extinct, according to Audubon magazine. These birds are a prime example of how quickly and efficiently humans can wipe out even the most common species. But is it just us, or can nonhuman animals drive other animals to extinction?
