One hundred rock ptarmigan (Lagopus muta), including 30 each of juvenile males and females, and 20 each of adult males and females, were collected in October 2006 in northeast Iceland to study their parasite fauna. Fourteen different parasite species were identified: 6 endoparasites (including the protozoans Eimeria muta, Eimeria rjupa; the heterok...

... The first week of October was chosen as our reference point to (1) control for seasonal changes in spleen and bursa size, as well as parasite measures (e.g., John 1994; Þórarinsdóttir et al. 2010;Akbar et al. 2012), and (2) sample the Ptarmigan population at the onset of winter because winter survival determines population change (Garðarsson 1988). Ptarmigan are free-flying wild birds; consequently, individuals could not be selected at random, but were collected by conventional walk-up hunting. ...
... The species associations we study are Icelandic Rock Ptarmigan (Lagopus muta, hereafter ptarmigan) known to be infected by 17 species of parasite, of which this study focuses on 12 (three endoparasitic species: two nematodes and a coccidian; and nine ectoparasitic species: five mites, three lice, and one fly; Stenkewitz 2017). Details of the chosen parasite species including their taxonomy, life cycle and life history, and degree of specialization are provided elsewhere, as are the rationales for their choice (Skirnisson et al. 2012, Stenkewitz et al. 2016. Briefly, the chosen parasite species were well represented parasitic fauna that could be identified to species (i.e., they were not exceedingly rare parasites, those for which ptarmigan could be considered accidental hosts, or parasites that were insufficiently described taxonomically-for those parasites, see Nielsen et al. 2020). ...
