The variety of snowy owls that glide above the Arctic tundra is in alarming decline because the birds face a gauntlet of threats. But the raptor’s path to authorized safety strikes at a sluggish tempo.
The enduring birds of the North are threatened by habitat loss as floor cowl turns into thicker and prey turns into harder to seek out. Collisions with automobiles, buildings and energy poles throughout migration are additionally inflicting numbers to dwindle.
The chook’s inhabitants is round 14,000 and dropping at greater than 30 per cent per decade.
It was assessed as threatened due to the “steepness of the decline in its numbers,” mentioned Syd Cannings, a retired biologist who served on the Committee on the Standing of Endangered Wildlife in Canada.
A scientific evaluation of declining inhabitants doesn’t routinely set off authorized safety. Researchers, federal, Indigenous and native governments perform in depth consultations on conservation efforts after a species is deemed threatened – a course of that may stretch on for 2 years or extra.
However the clock begins even earlier the place the committee’s scientists spend not less than two years finding out knowledge to find out a species’ standing, leaving the animals – on this case the snowy owl – susceptible for years earlier than conservation actions can take impact.
It may possibly take two years or extra within the North from the time an animal or chook is assessed as being threatened to being formally listed below federal regulation, Cannings mentioned.
“It takes so lengthy as a result of the federal government is being, I assume, very cautious,” he mentioned. “They do not need to simply say, ‘OK, growth. It is threatened,’ as a result of that has an impact on folks.”

Session is underway, says federal authorities
The committee meets twice a yr – within the spring and late fall – however the federal surroundings minister is given a duplicate of the report simply every year, Cannings mentioned. Then the minister then takes it to cupboard, which makes the ultimate resolution.
“It takes so much longer than a number of us would love.”
The committee’s evaluation is step one in a multi-step course of below the Species at Threat Act, mentioned Eleni Armenakis, spokesperson for Atmosphere and Local weather Change Canada, in an e mail.
The committee gave the surroundings minister its evaluation of the snowy owl on Oct. 16, she added.
The minister responded on Jan. 16 by extending session timelines to satisfy land claims obligations, Armenakis mentioned. “This session is underway.”
World risk inflicting decline in Arctic birds
The snowy owl, Cannings mentioned, is an umbrella species and an indicator of environmental well being, so if the chook is in bother, then different natural world aren’t doing properly both.
Snowy owls are discovered throughout the treeless Arctic tundra the place they largely feed on lemmings and geese. However they’re additionally recognized for travelling nice distances and are among the many most nomadic of birds, shifting round broadly searching for meals.
The primary risk confronted by the chook is a gradual change in its habitat introduced on by a warming world, Cannings mentioned.
“So many locations it used to nest are actually lined in shrubs,” he mentioned. “It is dropping all its productive lemming searching grounds on the southern fringe of the Arctic tundra. And the owls are having fewer and fewer locations to nest.”
Different threats going through the snowy owl embody avian flu, with knowledge compiled by Canadian Meals Inspection Company exhibiting not less than 15 instances since 2021.
They’re additionally hit by automobiles as they go down south from their properties, collide with buildings, get electrocuted by energy strains or are poisoned from consuming prey uncovered to rodent poison.
“There isn’t any single smoking gun to say what is definitely inflicting the decline in these chook numbers,” Cannings mentioned.
“Sadly, on this case, it is not one thing like stopping searching or, or one thing easy … that individuals can resolve both on their very own or the federal government can resolve to do one thing to assist. It is a extra difficult factor. It is a world risk.”
‘This hyperlink to the far North is a part of our tradition’
Cameron Eckert, director of the Yukon Chook Membership, mentioned the “perplexing query” surrounding a species just like the snowy owl is what steps ought to be taken for its conservation.
Sea ice is altering quickly and unpredictably and lemming populations naturally rise and fall in dramatic cycles — each of which affect snowy owl populations in methods which are properly past human management, he mentioned.
At the same time as the federal government works to chop greenhouse fuel emissions, local weather change is already having extra pronounced impacts on biodiversity, he added.
He mentioned the snowy owl has a charisma that resonates with folks in a approach many different species don’t.
“It carries this concept of a chook touring all the way in which from the Excessive Arctic to southern Canada for the winter,” he mentioned. “This hyperlink to the far North is a part of our tradition.”
