What are scientists theories on the dodo's extinction?

Answer 1

As it evolved in isolation it had no fear of predators and humans. Being a flightless bird it was easy prey for non-native species and humans. Also it is believed that their nesting grounds were destroyed as well.

Answer 2

As with many animals that have evolved in isolation from significant predators, the dodo was entirely fearless of people, and this, in combination with its flightlessness, made it easy prey for humans.[47] However, journals are full of reports regarding the bad taste and tough meat of the dodo, while other local species such as the Red Rail were praised for their taste. When humans first arrived on Mauritius, 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;[48] 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. The 2005 expedition's finds are apparently of animals killed by a flash flood; such mass mortalities would have further jeopardized a species already in danger of becoming extinct.[49]

Although there are scattered reports of mass killings of dodos for provisioning of ships, archaeological investigations have hitherto found scant evidence of human predation on these birds. Bones of at least two dodos were found in caves at Baie du Cap, fugitive slaves and convicts used these caves for shelters in the 17th century-but because of their isolation in high, broken terrain, they were not easily accessible to dodos.[50

Answer 3

The Dodo bird became extinct when the Portuguses ate them all in 100 years.
