Adaptive Evolution of Hawaiian Honey Creepers

Where do Hawaiian Honeycreepers live?Hawaiian honeycreepers are located in Pacific Ocean. They can only be found on the Hawaiian islands.

What is evolution? Evolution is the change of the gene pool of a population from generation to generation by processes like mutation, natural selection, and genetic drift.

The process of Evolution

How many different species are there?At least 56 species of Hawaiian honeycreepers known to have existed, although, all but 18 of them are now extinct.

What are Hawaiian Honeycreepers?Hawaiian honeycreepers are most famous for their adaptive radiation. They can only be found on the Hawaiian Islands. It went from one species to at least 54 other species.

What do they eat?Hawaiian Honeycreepers eat almost anything that is edible. They mostly eat nectar, insects, spiders, slugs, land snails, fruits, seeds and seed pods, tree sap, seabird eggs, and flesh of dead animals.

Each species evolved special feeding habits and a special beak shape to fill a different niche found on the specific island within the Hawaiian

This picture shows the different way the Hawaiian Honeycreepers beaks evolved.

One example of an Hawaiian Honeycreeper bird would be 'I'iwi, also known as Scarlet Hawaiian Honeycreeper.

Why are Hawaiian Honeycreepers evolving?As Honeycreepers adapted to their environment conditions on the Hawaiian Islands eventually their diet had to change. Their bill shapes changed from to something more convenient to their new lifestyle. Their songs and even feather color changed. Honeycreeper changed over time as they moved island to island.

Facts about 'I'iwi Hawaiian HoneycreepersIt uses its long sickle shape beak to search for nectar. It also feeds on insects and larvae. 'I'iwi usually breads from February to September. 'I'iwi was valued by hawaiians because of there orange-red feathers. They are common on many islands, but O'ahu and Moloka'i and are no longer found on Lana'i. The decline of the amount of 'I'iwi are due to the loss of habitat as their forest homes are being cleared out. And because of the disease Avian Malaria.

Which Island has the biggest impact on their evolution?Out of the whole Hawaiian archipelago it is believed that Oahu has the biggest impact of the Hawaiian Honeycreeper evolution. Oahu enables more adaptation and speciation for the Hawaiian honeycreepers.

FactsHoneycreepers fall within a clade exhibiting a generally high evolutionary flexibility in bill morphology.The magnitude of bill variation among the honeycreepers is similar to that of the entire passerine radiation, this dramatic morphological radiation represents an extreme manifestation of a general clade–specific ability to evolve novel morphologies.Clade – A group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics.Morphology - The study of the forms of things, in particularPasserine – RadiationMorphological – The relating to or concerned with the formation of admissible words in a language.Manifestation – An event, action, or object that clearly shows or embodies something, esp. a theory or an abstract idea: "manifestations of global warming".Magnitude - The great size or extent of something: "the magnitude of the task"

What is adaptive radiation?Adaptive radiation is the evolution of many species from one ancestor.
