Abstract/OtherAbstract:
Abstract The Socorro dove Zenaida graysoni, endemic to Socorro Island, was last reported in the wild in 1972. Fortunately, the species has been propagated in zoos in Europe and the USA, and plans are underway to reintroduce it to its native habitat. This will be the first known attempt to return a bird species extinct in the wild to its ancestral island. In order to assess the disease threats the Socorro dove may face, the avifauna of Socorro Island, with a specific focus on Socorro ground doves Columbina passerina socorrensis and mourning doves Zenaida macroura, as well as Socorro doves in captivity, were screened for blood parasites of the genera Plasmodium, Haemoproteus, Leucocytozoon and Trypanosoma spp. We found Haemoproteus spp. in 17 (74%) of 23 Socorro ground doves, 23 (92%) of 25 mourning doves and 3 (14%) of 21 northern mockingbirds, all other bird species did not show infections. Here we report the phylogenetic analysis of 19 distinct lineages of Haemoproteus spp. detected in birds of Socorro Island and compare their evolutionary relationships to parasites detected in the avifauna of the Galápagos Islands, continental Latin America and Europe. Microscopic examination revealed one mourning dove infected with Plasmodium (Haemamoeba): thus underscoring the importance of using both PCR and microscopy when analyzing bird blood samples for hemosporidian parasites. This study confirms that the Socorro dove will most likely be exposed to Haemoproteus spp. that currently infect mourning doves and Socorro ground doves of Socorro Island. A monitoring program for both birds and vectors should be implemented to establish the prevalence of Plasmodium, and as a necessary conservation measure of critically endangered birds on the island.
