Dead birds near South Saskatchewan River suspected to be victims of avian flu
Dec 14, 2022 | 5:13 PM

MEDICINE HAT, AB – An outbreak of avian flu that came to our province in April has picked up once again and Alberta Fish & Wildlife officials believe it has reached our city.

Hatters began spotting dead and sick-looking Canada geese and mallard ducks along and near the South Saskatchewan River last week and reporting them to the province’s environment and parks office in Medicine Hat.

“We suspect that this might be again another reflection of the avian influenza outbreak,” says provincial wildlife disease specialist Margo Pybus. “The birds are concentrated on open water areas and you know they’re a little stressed because they’re trying to over-winter here and that’s probably triggered the virus to start to be a little more virluent or have its effect and killing the geese and the mallards.”...

Okotoks seeing an uptick of avian flu in geese
Written by Harrison O'Nyons Monday, Nov 06 2023, 1:30 PM

Cases of Highly Pathogenic Avian Influenza (HPAI) have seen a rise in Okotoks.

The H5N1 bird flu strain was first detected in Canada in 2021 and saw outbreaks in poultry flocks in 2021 and 2022, leading to culls in some areas.

Katrina Terrill, acting executive director at the Alberta Institute for Wildlife Conservation (AIWC), said this year they've mainly seen it affecting migratory birds.

"We are seeing it in a lot of bird populations, and it seems particularly this year, a lot of geese populations."

It's been spreading much more in the United States, likely due to the more accommodating climate and higher density of poultry populations, with upwards of 61 million birds affected by HPAI.

The AIWC keeps medical records of animals taken in, and while the spread hasn't been as bad this year, they've noticed an uptick in confirmed HPAI cases in Okotoks and Airdrie...

Early signs of avian influenza impacting waterfowl in Lethbridge
By Sarah Jones Global News
Posted December 20, 2023 9:04 pm
Updated December 20, 2023 9:05 pm

Last winter, hundreds of birds died from avian influenza in Lethbridge and according to experts the risks associated with the deadly virus are starting to re-appear.

Dr. Everett Hanna at the School of Environmental Sciences at Lethbridge College says, “We’re just starting to see I think the prevalence or at least the effects of the disease on waterfowl’s sort of spiking.”

Hanna says the infection typically spreads when there’s a conglomerate of birds together, when the weather is tough and when there is poor access to food.

The Government of Canada estimates that nearly 10,922,500 birds in flocks have been impacted from the avian flu as of Dec. 14, with 1,858,000 birds affected in Alberta alone.

However, Hanna says this past spring wasn’t as bad as some people had anticipated in terms of deaths, and indicates the summer was also quite quiet, which is typical for that time of year. The fall is when they tend to see a spike in cases.

“This year, it’s been very dry,” said Hannah. “Very warm without the expectation of October I guess. So, we haven’t really seen that stress yet so we’ll see what will be written in terms of this year’s story. Certainly, last year, this time we saw a real cold snap, a couple of them, but one in particular this time last year, really nailed the birds pretty hard.”

Local birder, Ken Orich is a volunteer for the Christmas Bird Count and says he’s already come across numerous dead birds or ones showing early signs of infection around Lethbridge...
