A devastating blow to conservation efforts: Avian flu has claimed the lives of two endangered whooping cranes near Saskatoon, marking the first time this deadly virus has been detected in the wild population of these majestic birds.
This tragic discovery underscores the ongoing threats faced by these already vulnerable creatures. The news comes from Saskatchewan, where wildlife officials confirmed the presence of avian influenza in the deceased cranes.
Scientists are deeply concerned, as these are the first confirmed cases of avian flu in the wild whooping crane population. But here's where it gets controversial: The whooping crane population, once numbering around 10,000 birds in Canada, was brought to the brink of extinction in the 1940s, with only 15 individuals remaining. Over-hunting and habitat loss were the primary culprits.
The first crane was discovered in October. A wildlife biologist, Mark Bidwell, found the scavenged remains of the crane in a field about 90 kilometers east of Saskatoon. The second crane was found about 100 kilometers northwest of the first.
Conservation efforts, including collaborations between American and Canadian scientists, have helped the whooping crane population rebound to approximately 560 wild birds. These birds belong to the Aransas-Wood Buffalo population, which migrates to the Gulf Coast of Texas for the winter and returns to Canada each spring to breed.
Bidwell believes the cranes likely contracted the virus from sharing habitat with other birds, such as geese. The virus attacks infected birds' tissues, leading to neurological damage and death. Trent Bollinger, a professor at the Western College of Veterinary Medicine and regional director and pathologist at the CWHC, confirmed that these are the first two confirmed cases of avian influenza in North America’s wild whooping crane population.
And this is the part most people miss: The discovery of these two deaths is especially alarming. In September, a captive whooping crane in a Wisconsin breeding program died from avian flu. Bollinger and Bidwell urge the public to report any sick or dead birds to the CWHC reporting line and to avoid touching the animals without proper protective gear.
