Leucocytozoonosis in Canada Geese at the Seney National Wildlife Refuge
A history is given of the Seney National Wildlife Refuge and the losses of goslings of Canada geese ( Branta canadensis ) recorded since inception of the refuge in 1935. Since 1960, when more reliable data became available, losses have been extensive every 4 years. Gosling deaths are attributed to the infection with Leucocytozoon simondi . The blackfly ( Simulium innocens ) is considered to be the prime vector in the transmission of this blood parasite to goslings.
