As the number of avian flu cases in B.C. climbs into the summer, the provincial SPCA is advising British Columbians to pause bird feeders and baths.
But not everyone agrees.
Since January, 44 wild birds in B.C. have been tested for highly pathogenic avian influenza (HPAI), with nationwide spikes in the disease occurring late May and early July. Between February and June, a bald eagle, wood duck, Northwestern crow, great blue heron, peregrine falcon and two great horned owls around the province have tested positive.
In Greater Victoria, one Canada goose near Rock Bay and another by View Royal were tested for HPAI in June.
91裸聊视频淭his strain is thought to have come from migrating birds,91裸聊视频� said Andrea Wallace, BCSPCA wild animal welfare manager, adding that it first entered Eastern Canada from the U.S. before 91裸聊视频渜uickly spreading across the country and into B.C.91裸聊视频�

91裸聊视频淲aterfowl can actually carry the disease and not show any signs of illness,91裸聊视频� Wallace said.
She called bird feeders, which can attract fowl and other animals and quickly grow unsanitary, a 91裸聊视频済reat recipe for disease spread.91裸聊视频� Not only do feeders cause unnatural wildlife congregations, they also transfer disease when birds eat below them on the ground where their feces accumulates.
A bird bath regularly scrubbed, disinfected and refreshed likely poses little issue for birds, Wallace noted, but most people don91裸聊视频檛 put in that level of care.
All bird species can contract HPAI, but Ann Nightingale of the Rocky Point Bird Observatory explained waterfowl, shorebirds and raptors that prey and scavenge along the water remain at highest risk.
But Nightingale said temporarily removing bird feeders and emptying bird baths is unnecessary, explaining that HPAI hasn91裸聊视频檛 traditionally been an issue for wild birds in North America and primarily affects chickens and other domestic flocks.
91裸聊视频淚t91裸聊视频檚 devastating to poultry farmers to lose tens of thousands of birds to this flu,91裸聊视频� she said.
The Canadian Food Inspection Agency, in a statement to Black Press Media, said waterfowl and other wild birds aren91裸聊视频檛 normally affected by HPAI, but are 91裸聊视频渘atural reservoirs of influenza viruses91裸聊视频� and can transmit the disease to domestic birds. HPAI can reach birds via infected poultry and contaminated manure, litter, clothing, footwear, vehicles, equipment, feed and water.
91裸聊视频淲ild birds are believed to be responsible for a number of these outbreaks,91裸聊视频� the statement read, referencing the 91裸聊视频渦nprecedented number91裸聊视频� of HPAI cases affecting farmed birds across Canada, most recently in Quebec.
While the agency only listed biosecurity practices for farmers, maintaining high sanitation standards and keeping poultry and wild birds separated were dominant themes.

She recommended residents move bird feeders around their property, clean them more thoroughly and often, avoid spilling contents on the ground and consider not refilling them for several weeks to prevent bird clusters. Birds sick with HPAI may appear sluggish and extra fluffed up and, as Nightingale put it, actually look sick.
With some bird feeders taken down earlier this year in response to the outbreak. many bird watchers were disappointed, she added. 91裸聊视频淚t was sad this spring the number of people who were saying they missed having the birds in their yard.91裸聊视频�
Asked how long this outbreak might last, Wallace replied, 91裸聊视频渢hat91裸聊视频檚 the million-dollar question and we really don91裸聊视频檛 know.91裸聊视频� The BCSPCA hadn91裸聊视频檛 expected to still be hearing of new HPAI cases by this point.
