blood parasites of blue grouse (dendragapus obscurus) in western north america.three hundred thirty-three blue grouse (dendragapus obscurus) were examined for blood parasites from 11 sites: southern yukon territory, southeast coastal alaska, northern and central interior british columbia, south coastal british columbia, northcentral washington, southcentral oregon, northwestern california, eastcentral nevada, northwestern colorado, and westcentral montana. three species of protozoan parasites (leucocytozoon lovati, haemoproteus mansoni, trypanosoma avium) and a splendidofi ...19911920670
interspecific variability of prevalence in blood parasites of adult passerine birds during the breeding season in alaska.blood parasite prevalence based on microscopic examination of stained blood smears was determined in adults of 11 passerine bird species sampled during their breeding season (may and june 1997-98) in interior alaska (usa). these species included primarily nearctic migratory species such as the dark-eyed junco (junco hyemalis) and neotropical migratory species such as the blackpoll warbler (dendroica striata), alder flycatcher (empidonax alnorum), swainson's thrush (catharus ustulatus), northern ...200111272501
blood parasitaemia in a high latitude flexible breeder, the white-winged crossbill, loxia leucoptera: contribution of seasonal relapse versus new inoculations.we measured seasonal changes in the prevalence of haematozoa (leucocytozoon fringillinarum, haemoproteus fringillae, and trypanosoma avium) in free-ranging white-winged crossbills, loxia leucoptera, over 1.5 year in fairbanks, alaska, usa. this prevalence was low during early winter. l. fringillinarum prevalence increased in late winter/early spring, in the absence of vectors, suggesting relapse of latent infection. by contrast, the prevalence of t. avium and h. fringillae did not increase until ...201019849885
