In a survey of the coccidia of 362 wild geese and swans from Canada and the United States, including subspecies and populations of Anser albifrons, A. caerulescens, A. rossi, Branta canadensis, B. bernicla, and Olor columbianus, the following coccidia were found: Eimeria anseris, E. brantae, E. fulva, E. hermani, E. magnalabia (syn., E. striata), E. nocens, E. truncata, E. clarkei n. sp., E. farri n. sp., and Tyzzeria anseris. Reports in the literature on the species of coccidia occurring in wild and domestic geese and their prevalence and geographic distribution are summarized with particular reference to North American flyways.
