Thousands of double-crested cormorants and gulls in Saskatchewan may
have been killed by an outbreak of Newcastle disease, provincial
wildlife officials say.
"Sick and dead cormorants and gulls were reported in early August,"
Saskatchewan's Ministry of Environment reported Friday in a news
release, noting that as of Aug. 12 about thousands of dead birds were
found, with many others appearing sick.
The areas affected are Jackfish Lake and Meadow Lake Provincial Park,
northwest of Saskatoon.
The province said that preliminary examinations of the dead birds
suggests they were killed by the Newcastle disease virus, though
further testing is being done to confirm that.
A government scientist told CBC News Friday that it is not unusual for
such outbreaks to take place in nature.
Yeen Ten Hwang is a wildlife health specialist with the environment
ministry.
"We have a pretty healthy [and] an increasing population of cormorants
nesting in the area," she said. "And we are looking at perhaps 1,000
out of tens of thousands of birds. So in fact, in context, it's only
affecting a small population of the cormorants and gulls."
According to the province, there is no health risk to humans, although
people who see a dead bird are being told not to touch it.
The strain of the virus found in wild birds is not considered lethal to
domestic poultry, according to the ministry release.
