First Occurrence of the Grey Fox, Urocyon cinereoargenteus, in New Brunswick: a Climate-change Mediated Range Expansion?

Donald McAlpine, James D. Martin, Cade Libby


The first occurrence in New Brunswick of the Grey Fox (Urocyon cinereoargenteus), a threatened species in Canada, is documented based on a 4.3 kg subadult male trapped in the southwestern corner of the province. This is an approximate range extension of 135 km from the most northerly Maine occurrence and may reflect a larger North American range expansion underway since 1930-40, perhaps in response to warming climate.
