Evidence for Haemosporidian Parasite Infections in Spectacled Eiders ( Somateria fischeri) Sampled in Alaska, USA during the Breeding Season.

We assessed hematozoa infection in Spectacled Eiders ( Somateria fischeri) at two areas in Alaska, US. No Haemoproteus or Plasmodium species were detected. Leucocytozoon prevalence was 6.5% for adults across sites and 41.9% for juveniles sampled in the Arctic, providing evidence for local transmission. All Leucocytozoon haplotypes were previously detected in waterfowl.
