Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists.

a) Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
b) If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
