| Abstract: | Amidostomum anseris, a roundworm which occurs under the horny lining of the gizzard in birds, is a widely distributed parasite in Canada geese. It is also reported from snow geese (Chen hyperborea). Although the extent of erosion of the gizzard wall by these worms is not precisely correlated with the number of worms present, it is usually severe in Canada geese when 150 or more worms are present. Gizzard worm infection is considered a contributing factor to low weights, poor condition and to losses among the Canada geese which winter at the Pea Island National Wildlife Refuge in North Carolina. The mean number of gizzard worms per bird is considerably higher for Pea Island than for areas where winter losses have not been reported. |
