Is it possible, or has it ever happened that one species of animal could make extinct another species of animal?


I am not referring to humans. I am wondering if one species of animal ever ate so much of another species of animal that it made it extinct. I am trying to find out if only humans have that distinction.

    You can't just take humans out of the equation, since we are animals. In the great ape family, specifically. Feral/ abandoned cats is one I can think of since you don't want humans, though we top the list

    Yes. I've heard stories of pet cats allowed outside killing so many endangered birds that they went extinct

    Yes - link gives examples of extinction caused by Man.

    Yes there are countless cases. 

    The Dingo is a canid [dog] brought by humans to Australia, but  they are attributed to many of the extinctions in the continent, they also depleted the tasmanian tiger population, completely eliminating them from mainland Australia [they competed for the same niche]. 

    Tasmania kept many native Australian animals alive until recently because they were isolated from Dingoes and the rest of Australia. 


    When North and South American continents collided roughly 3 million years ago, many animals crossed and many more went extinct. 

    The decline in terror bird species is attributed to the arrival of carnivora from north America.

    Yes. Humans have caused the extinction of many species. There are other ways for 1 species to make another extinct in the wild, and it is called competitive exclusion. If two species have similar requirements, then either one of them will become extinct or one or both may evolve to be less similar. When South America collided with North America starting about 5 million years ago, many marsupials have become extinct in a event known as the Great American Faunal Interchange.  Many species of placental mammals, including cats, foxes and camelids migrated from North America to South America and the result was the extinction of large numbers of marsupials. 

    Also, the introduction of the brown tree snake onto the Island of Guam has resulted in the extinction of man birds on that island, as the snakes ate the birds to extinction. The introduction of goats onto the Galapagos Islands have caused he extinction of many giant tortoises on those islands.

    Yes, there are many examples. The predator doing the killing is usually not native to the area but introduced like cats, dogs and rats. The Stephens Island wren ( Traversia lyalli ) was only found on that New Zealand island. The lighthouse keeper's cat killed ten of them in 1894 and they were extinct by 1900. The Macquarie Island parakeet and the Macquarie Island rail were extinct by 1900, exterminated by cats and rats introduced by sealers. The kakapo, a flightless New Zealand parrot is extinct on the mainland due to rats taking the eggs. Some years ago, an island was cleared of rats and cats and the remaining kakapos were released there and are surviving well but they will probably never be reintroduced to the mainland. There are many other examples.

    Yes.  It happens all the time.  Introducing pigs, goats, rats, mongoose, brown tree snakes, predatory snails, dogs, and cats to islands have caused a lot of extinctions.

    If you're looking for a more natural event, when North America and South America became connected, animals flowed both ways.  Lots of extinctions occurred, and South American marsupials were almost completely outcompeted, due to the influx of North American placental mammals.

    Approximately 99% of all species that have ever existed are extinct.
