The new cases bring the total count to three cases of Avian flu in the territory. The two ravens were found dead just a few days apart, on Oct. 26 and Oct. 28.

A wildlife pathologist in Saskatoon says his lab is testing several skunks and fox kits showing neurological signs that could be caused by avian flu. The transmission to mammals is not a surprise to Bollinger, who said cases have been showing up in the United States. There are other viral diseases - such as distemper and rabies - that cause similar symptoms in these species.

Alaska State Veterinarian Dr. Robert Gerlach said they have now confirmed avian flu in several bald eagles on Unalaska in the Aleutian Islands, several Canada geese in the Anchorage area, and a Canada goose in Delta Junction.

"We had an unusually large number of calls about skunks that were acting strange or being found dead and it was all within the area where we had confirmed that the avian influenza virus was present in the snow geese," Dr. Margo Pybus, a provincial wildlife disease specialist with Fish and Wildlife Alberta Environment and Parks, said. "We believe that the skunks are feeding on the dead geese and they are getting enough virus that it’s actually affecting the skunks."
