Question: what caused the dodo bird to become extinct

title: Dodo
text: Like many animals that evolved in isolation from significant predators , the dodo was entirely fearless of humans . This fearlessness and its inability to fly made the dodo easy prey for sailors . Although some scattered reports describe mass killings of dodos for ships ' provisions , archaeological investigations have found scant evidence of human predation . Bones of at least two dodos were found in caves at Baie du Cap that sheltered fugitive slaves and convicts in the 17th century , which would not have been easily accessible to dodos because of the high , broken terrain . The human population on Mauritius ( an area of 1,860 km or 720 sq mi ) never exceeded 50 people in the 17th century , but they introduced other animals , including dogs , pigs , cats , rats , and crab - eating macaques , which plundered dodo nests and competed for the limited food resources . At the same time , humans destroyed the forest habitat of the dodos . The impact of the introduced animals on the dodo population , especially the pigs and macaques , is today considered more severe than that of hunting . Rats were perhaps not much of a threat to the nests , since dodos would have been used to dealing with local land crabs . 

Answer: answer: Due to the fact of having no fear of humans and its inability to fly, dodo was an easy prey for sailors. The introduction of dodo eating animals, in addition to destroying the forest habitat of the dodos also helped cause the bird to become extinct.
