Video shows unusual circling behavior of a brant goose filmed by a local hunter near Golovin, Alaska. Although the cause is unknown, this type of behavior is according to USGS, "highly suggestive" of an infection with Highly Pathogenic Avian Influenza (HPAI).

This video shot on Thursday May 19th, shows the erratic circling behavior of a Canada goose. Although the cause is unknown, this type of behavior is according to USGS, "highly suggestive" of an infection with Highly Pathogenic Avian Influenza (HPAI).

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.

The territorial government issued a public service announcement earlier this week, warning people about a highly pathogenic strain of avian influenza. N.W.T. hunters say they are worried about harvesting birds that may have the virus.

A passenger on a small commercial plane flying between Nome and Golovin reported seeing 5-6 swans all motionless, floating on a pond. The reason of the behavior is unknown.

The flu now affecting birds in Saskatchewan is a severe strain of influenza that has mingled genes from Eurasia and North America, according to Dr. Trent Bollinger, a professor at Western College of Veterinary Medicine (WCVM) and a pathologist. Bollinger said that the severity of the disease, which he says is the H5N1 strain, depends on the species.

The Canadian Food Inspection Agency say avian influenza has been detected in additional poultry flocks in southern Alberta as well as in Saskatchewan.
