Threatened wildlife including turtle doves and skylarks could benefit from a scheme which has been launched to create natural habitats at solar farm sites.
Alberta's energy regulator is investigating the deaths of 30 blue herons at a Syncrude Canada oil sands site in the northern part of the Canadian province, the agency and company said on Saturday.
The Alberta Energy Regulator said it sent investigators to the Syncrude Canada Mildred Lake site, which is about 40 km (25 miles) north of Fort McMurray.
In 2010, Syncrude was fined C$3 million ($2.29 million) for negligence in the 2008 deaths of 1,600 ducks in a toxic tailings pond, a case that fueled international concern about the environmental impact of developing Canada's oil sands.
