A family of birds commonly called the Hawaiian honeycreepers is unique to the Hawaiian
Islands, which are located in the Pacific Ocean far from major landmasses. The honeycreepers have
similarly shaped bodies and are about the same size. They differ sharply, however, in plumage color
and beak shape. Each species of honeycreeper has a beak that is adapted to the type of food it eats
and occupies its own niche. A niche is the role of a particular species in a community regarding
food, space, reproduction, and how it interacts with nonliving parts of its environment.
The honeycreepers are thought to have evolved from a single ancestral
species that came to the Hawaiian Islands millions of years ago. The pattern of evolution shown by
the honeycreepers is known as adaptive radiation. Adaptive radiation is one example of divergent
evolution, a pattern of evolution in which species that were once all similar to the ancestral
species became more and more distinct. Divergent evolution occurs when species begin to adapt to
different environmental conditions.
