Western Grebe recuperates on shore of Wabamun Lake after oil spill near Edmonton.
A disabled Western Grebe tries to warm himself in the sun, on the shore of the oil-soaked Lake Wabamun, near Edmonton, August 13, 2005. The Grebe loses its ability to maintain body heat when it becomes covered in the oil and needs the sun to keep warm. Alberta is eyeing charges against Canadian National Railway for not telling it that a derailment last week might have contaminated a popular lake with a hazardous chemical, a provincial government official said on Tuesday.
