The dodo bird is an extinct flightless bird species that lived on the island of mauritius, in the indian ocean. written records as well as fossil remains indicate that human behavior is directly responsible for the dodo bird’s eventual extinction. there are three main ways in which humans contributed and accelerated this extinction.

First, the dodo bird was exhaustively hunted by sailors looking for an easy snack. the dodo was the perfect target. because the dodo bird’s natural environment lacked any significant natural predators, dodos were innately trusting and were fearless of people, making them an easy prey. this feature, combined with lightlessness and inability to escape the hungry sailors, further contributed to their eventual demise and extinction.

Another way in which human action directly contributed to the extinction of the dodo bird is deforestation. early sailors and settlers of mauritius cleared large areas of forest for the construction of settlements. deforestation destroyed the natural habitats of the dodo bird and eliminated resources the dodo depended upon for sustenance. the destruction of the forest habitats forced dodos into to smaller and smaller areas meaning that they were also forced to compete with each other for resources to survive.

A third impact humans had on the dodo is disease. sailors, in addition to bringing along their appetites, carried pathogens to which the dodo had no immunity. when these diseases were introduced into the previously isolated dodo environment, the result was a rapid decimation of the dodo bird. the dodo had no time to develop resistances and thus disappeared almost overnight.
