This is a List of adaptive radiated Hawaiian honeycreepers by form; these are the Hawaiian honeycreepers, especially the extinct forms, lost through late-European colonization. (These are adaptive radiative equivalents.)
Hawaiian honeycreepers are a group of small birds endemic to ... Their great morphological diversity is the result of adaptive radiation in an insular environment.
The Hawaiian honeycreepers form a large, highly morphologically diverse species group of birds that began radiating in the early days of the Hawaiian archipelago. While today only 17 species are known to persist in Hawaii (3 more may or may not be extinct), there were more than 50 species prior to Polynesian colonization of the archipelago ...
Most of the members of this family listed here are "Hawaiian honeycreepers". These endemic birds were formerly placed in their own family, Drepanididae. The wide range of bills in this group, from thick finch-like bills to slender downcurved bills for probing flowers, have arisen through adaptive radiation , where an ancestral finch has evolved ...
The Hawaiian honeycreepers are generally specialists both in diet and in habitat. This has left them very vulnerable directly and indirectly to the generalist invaders that have been introduced to the islands. [6] Other birds have provided direct competition for resources with the honeycreepers as well as brought disease (such as avian malaria).
Paroreomyza, along with Oreomystis (although their alliance is disputed), [2] is the second most basal genus of Hawaiian honeycreeper to survive to recent times, with the most basal being the recently extinct poʻouli (Melamprosops phaeosoma), with Paroreomyza and Oreomystis having diverged from the rest of the lineage about 4.7 million years ago.
The Oʻahu ʻamakihi (Chlorodrepanis flava) is a species of Hawaiian honeycreeper in the family Fringillidae. The male is rich yellow below, sharply contrasted with greenish upper parts. Females are duller and have two prominent wing-bars. It has a total length of approximately 4.5 inches (11 cm).
Plants got to Hawaii via the three W's: wind, bird wings or waves. After arriving, they evolved to take advantage of a variety of new habitats. A single colonizing ancestor often changed or developed into many new endemic species; this is known as adaptive radiation. There are more than 10,000 species of endemic Hawaiian plants, birds and insects.
