Impacts of Introduced Avian Diseases on the Decline and Extinction of Native Hawaiian Honeycreepers

How is avian pox and malaria impacting native Hawaiian honeycreepers? USGS scientists in Hawaii conduct surveys, develop new diagnostic tools, and test management strategies to understand the impacts of these introduced vector borne diseases on native Hawaiian wildlife.

Effect of Malaria on Experimentally Infected Hawaiian Birds

USGS scientists build on the research of ornithologists in the 1800's and 1950's to show whether native Hawaiian birds are in fact highly susceptable to mosquito-transmitted avian diseases such as pox and malaria. The results help explain current population patterns and could potentially aid resource managers in selecting birds for restoration in More...

Seasonal Prevalence and Transmission of Avian Pox and Malaria in Hawaiian Forest Birds

Many native Hawaiian forest birds have become endangered and extinct, possibly due to introduced avian diseases. Scientists use genetics, long term studies, and sentinel chickens and canaries to learn the prevalence and impacts of malaria and avian pox on native Hawaiian forest birds.
