epizootic necrotic enteritis in wild geese.outbreaks of a disease characterized by severe necrotic enteritis occurred among canada geese (branta canadensis), lesser snow geese (anser caerulescens), ross' geese (a. rossi), and white-fronted geese (a. albifrons) on lakes in saskatchewan and manitoba during the autumn of 1983, 1984 and 1985. ducks using the lakes were apparently not affected. lesions in the geese closely resembled those described in enteritides in other species associated with the proliferation of clostridium perfringens in ...19873625893
evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese.quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species' distribution. at cape churchill, manitoba, canada, recent declines in breeding eastern prairie population canada geese (branta canadensis interior) has coincided with increasing populations of nesting lesser snow geese (chen caerulescens caerulescens) and ross's geese (chen rossii). we conducted a spatial analysis of point patterns using canada goose nest locations and nest fate, and ...201324312520
mortality of geese as a result of collision with the ground.two incidents are reported in which groups of migrating wild geese were found dead in agricultural fields in southern manitoba during spring. in each case, the birds died overnight and poisoning was suspected; however, the birds had lesions of severe traumatic injury. the first incident, in 1985, involved about 150 lesser snow geese (anser caerulescens caerulescens); the second, in 2003, involved 62 canada geese (branta canadensis). both incidents occurred on dark, moonless nights. one possible ...200516107686
