Hawaiian Honeycreepers
Hawaiian honeycreepers are a group of songbirds endemic to the Hawaiian islands, all descended from a single species that arrived from the mainland six to seven million years ago. They are considered a dramatic example of adaptive radiation, a phenomenon in which a single species rapidly diversifies into many different ones. At one point, there…

Avian Malaria
One of the major threats to Hawaiian honeycreepers is a deadly, mosquito-borne disease called avian malaria. Similar to malaria that infects humans, the disease is caused by parasites that enter honeycreepers’ bloodstreams when they are bitten by a disease-carrying mosquito.

Endemic Species
When a species has a native range that is confined to an isolated patch of land or body of water, it is known as an endemic species.
-
Adaptive Radiation
When a single ancestor species rapidly evolves into many different, specialized species, this is known as adaptive radiation.
