Why are dodo birds extinct

Sailors visited their island and killed some for food, but the bigger problem was they also brought pigs & rats that ate the eggs.

When humans first arrived on Mauritius Island, they also brought with them other animals that had not existed on the island before, including dogs, pigs, cats, rats, and Crab-eating Macaques, which plundered the dodo nests, while humans destroyed the forests where the birds made their homes. The impact these animals—especially the pigs and macaques—had on the dodo population is currently considered to have been more severe than that of hunting since humans did not desire the taste of the bird They are to have become extinct in 1662..

Because they all died. Just kidding, deforestization and from foreign predators being introduced to the region.
