Imperial Oil Ltd. is reporting the deaths of 50 birds that landed on tailings areas near its Kearl oilsands project in northern Alberta.
Imperial says more than 100 birds per day, mainly grebes and shorebirds, have landed on the ponds over several days, mostly on open water.
Jon Harding, an Imperial spokesman, says some of the oily birds have been taken to a rehabilitation centre in Edmonton where they will be cleaned and assessed.
Imperial says the birds landed despite active deterrent systems including radar detection, noise cannons, eye-safe lasers, scarecrows, and long-range noise making devices.
It says the system is maintained and operated by a well-trained, experienced and dedicated team that works throughout the annual bird migration and breeding season.
Imperial says it believes exhausted birds landed at the Kearl site in spite of the deterrents because most of the natural water bodies in the area are still frozen.
