Helminths of Hudsonian godwits, Limosa haemastica, from Alaska and Manitoba.

Abstract

In total, 21 Hudsonian godwits, Limosa haemastica (Charadriiformes: Scolopacidae), were examined for helminths, 10 from Bristol Bay, Alaska, and 11 from Churchill, Manitoba. Seventeen species of helminths (9 trematodes, 6 cestodes, 2 nematodes) were collected, but only 1 trematode species, Plagiorchis elegans, was found in common between the 2 sample sites. All 17 species are new records for this host and 2 cestodes, Capsulata edenensis and Malika limosa, are new records for North America. In general, both prevalence and intensities were low, and species richness ranged from 1 to 6 (mean = 2.4). Most of the differences in the helminth faunas between the 2 sites were attributed to difference in habitats, freshwater in Manitoba versus saltwater in Alaska.
