A survey of adult Canada geese, Branta canadensis, at Kortright Waterfowl Park in Guelph, Ontario, Canada, showed that 20% of the geese sampled passed small numbers of coccidial oocysts throughout the winter months (October 1975 to February 1976). Four species of coccidia, Eimeria hermani Farr, 1953, E. magnalabia Levine, 1951, E. truncata (Raillet and Lucet, 1891) Wasielewski, 1904, and Tyzzeria parvula (Kotlan, 1933) Klimes, 1963, were identified from the samples examined. A hitherto undescribed Isospora sp. was found in 5% of the fecal samples. It is named Isospora anseris and described as a new species. In the spring goslings were found to be passing E. hermani oocysts between the 8th and 13th day of hatching.
