The mystery surrounding dozens of paralyzed birds that were discovered in B.C.'s northeast has deepened after veterinarians ruled out West Nile virus but found wing and leg fractures.But that's not all. CBC also reported:
Last month, dozens of paralyzed ravens and crows were dropped off at a Dawson Creek rehabilitation clinic, sparking concerns about West Nile, which can also affect humans.
Despite efforts to save them, all 30 birds eventually died.
Animal experts are trying to figure out what may have killed dozens of black birds that fell from the sky in Winnipeg's North End on Wednesday [August 7, 2013].
Conservation officers have picked up more than 50 dead birds near the intersection of King Street and Dufferin Avenue, while the Winnipeg Humane Society took in 11 birds that were still alive.
Erika Anseeuw, the humane society's director of animal health, said all the living birds were reasonably bright and active, although they cannot stand or fly.
The birds will be euthanized and sent to a pathology lab for autopsies.
Anseeuw would not speculate on what exactly may have killed the birds, but she suspects they may have accidentally gotten into something.
"My suspicion is this is what it's going to be rather than any kind of apocalyptic foretelling of birds falling from the sky," she said in an interview with CBC Radio's Up to Speed program.
Possible factors may include exposure to disease or toxins, Anseeuw said.
"Possible factors may include exposure to disease or toxins." Isn't that what we heard about the bees?
