Blood parasites of American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus) in Florida, U.S.A.
Blood films from 46 fish crows (Corvus ossifragus Wilson) and 42 American crows (Corvus brachyrhynchos Brehm) from Florida, U.S.A., were examined for blood parasites. Haemoproteus picae Coatney and Roudabush, Haemoproteus danilewskii Kruse, Trypanosoma avium (Danilewsky), and microfilariae of an unidentified filarioid were identified from both species of crows. An unidentified species of HaemoprotAuthorsRobert J. Dusek, Donald J. ForresterSerological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii Amakihi
Six of seven Hawaii Amakihi (Hemignathus virens) with chronic malarial infections had no increases in peripheral parasitemia, declines in food consumption, or loss of body weight when rechallenged with the homologous isolate of Plasmodium relictum 61 to 62 days after initial infection. Five uninfected control amakihi exposed at the same time to infective mosquito bites developed acute infections wAuthorsCarter T. Atkinson, Robert J. Dusek, Julie K. LeasePathogenicity of avian malaria in experimentally-infected Hawaii Amakihi
The introduction of avian malaria (Plasmodium relictum) and mosquitoes (Culex quinquefasciatus) to the Hawaiian Islands (USA) is believed to have played a major role in the decline and extinction of native Hawaiian honeycreepers (Drepanidinae). This introduced disease is thought to be one of the primary factors limiting recovery of honeycreepers at elevations below 1,200 m where native forest habiAuthorsCarter T. Atkinson, Robert J. Dusek, K.L. Woods, W.M. IkoWildlife disease and conservation in Hawaii: pathogenicity of avian malaria (Plasmodium relictum) in experimentally infected Iiwi (Vestiaria coccinea)
Native Hawaiian forest birds are facing a major extinction crisis with more than 75% of species recorded in historical times either extinct or endangered. Reasons for this catastrophe include habitat destruction, competition with non-native species, and introduction of predators and avian diseases. We tested susceptibility of Iiwi (Vestiaria coccinea), a declining native species, and Nutmeg MannikAuthorsC. T. Atkinson, K.L. Woods, Robert J. Dusek, L.S. Sileo, W.M. IkoEpidemic pox and malaria in native forest birds
Studies by Warner in the 1950’s and van Riper in the 1970’s identified disease as a potential limiting factor in the distribution and abundance of Hawaii’s native forest birds. Mosquito-transmitted protozoan and viral infections caused by malarial parasites and pox virus were especially significant. Both organisms were introduced to the islands after the arrival of Europeans and are thought to havAuthorsC. T. Atkinson, R. J. Dusek, W. M. IkoAvian malaria fatal to juvenile I'iwi
