To sniff out the undisputed Hawaiian honeycreeper
, Pratt had an assistant place specimens of dead honeycreepers and a Poo-uli in opaque cloth bags.
The adaptive radiation of the Hawaiian honeycreepers
(Fringillidae: Drepanidinae), with 21 genera and more than 50 species, is the largest avian radiation on an oceanic archipelago (Pratt et al.
The breeding biology of an endangered Hawaiian honeycreeper
, the Laysan Finch.
Bock (1979: 65) later placed Ciridops at the base of the red-and-black group "which may be representative of the founding stock of the Hawaiian honeycreepers
Genetic evidence for the origin and relationships of the Hawaiian honeycreepers
These behaviors are common to other Hawaiian honeycreepers
(Lepson and Freed 1997, Lepson and Woodworth 2001, Pratt 2005).
While habitat restoration is critical to the species' recovery, such efforts will take decades to benefit this highly specialized Hawaiian honeycreeper
and allow it to recolonize areas within its former range (Scott et al.
Smithsonian scientists and collaborators have determined the evolutionary family tree of the Hawaiian honeycreepers
using one of the largest DNA data sets for a group of birds and employing next-generation sequencing methods.
Annual epizootics of avian pox (Avipoxvirus) and avian malaria (Plasmodium relictum) likely led to the extinction of some species and continue to impact populations of susceptible Hawaiian honeycreepers
Among the larger Hawaiian Islands, palila are the sole surviving species of an extraordinary guild of about 21 species of Hawaiian honeycreepers
(an endemic subfamily of finches) that specialized on seeds or small fruits.
The endemic passerine avifauna of the Hawaiian Islands, particularly the endemic Hawaiian honeycreepers
(subfamily Drepanidinae) is often heralded as an outstanding example of adaptive radiation, equal to Darwin's finches from the Galapagos Islands in terms of diversity of bill types and number of species that descended from a common founder.
Some Hawaiian honeycreepers
have a highly coevolved relationship with the plants and moth pollinators upon which they feed.
Immunogenetics and Resistance to Avian Malaria in Hawaiian Honeycreepers
(Drepanidinae)" and "Newly Emergent and Future Threats of Alien Species to Pacific Birds and Ecosystems" deal with two of the major current threats facing Hawaiian avifauna.
The threats limiting Hawaiian honeycreepers
are not as pervasive in limiting 'Oma'o distribution and abundance.
For example, many of the "little green" Hawaiian honeycreepers
sing trills that are easily compared (Pratt et al.
