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. ...
... Icelandic Rock Ptarmigan (Lagopus muta, hereafter ptarmigan) are an ideal host species to study parasite aggregation because they have been subject to intense research as a game bird and have provided large numbers of replicates for ecological studies (Morrill et al., 2021;Nielsen et al., 2020;Stenkewitz et al., 2016); additionally, their parasite fauna are exceptionally well known and can be sampled with standardized protocols (Skírnisson, Thorarinsdottir & Nielsen, 2012;Stenkewitz et al., 2016). Parasites infecting ptarmigan from a focal population in northeast Iceland comprise a diverse set of ecto-and endoparasites, for which prevalence of several species correlates with host health indices and/or host population densities (Stenkewitz et al., 2016). ...
