What special biogeographical conditions on islands might permit the survival of flightless birds? Why has the colonization so often resulted in the extinction of such birds? The power of flight has been lost secondarily in representatives of many groups of birds; what are some possible evolutionary advantages?

Resource partitioning and abiotic and biotic factors that are benfiticial to birds. Colonization may drive species to extinction for hunting, (like the buffalo), ostriches are flightless birds, and so are penguins. Ostriches have strong legs and are able to run very fast, and penguins have a streamlined shape to help them swim.
