Oil Industry Lowballs Bird Deaths: Study

Annual death rate related to tailings ponds at least 30 times higher, ecologist says

new study says birds are likely dying in Alberta oilsands tailings
ponds at a rate that is at least 30 times higher than that suggested by
the oil industry.

The results add weight to arguments that depending on the industry to
monitor its own environmental impacts isn't working, said Kevin
Timoney, an ecologist who co-authored a paper on the subject with
Dalhousie University biologist Robert A. Ronconi.

The paper was published Tuesday in the Wilson Journal of Ornithology.

"We need to have credible scientific monitoring," said Timoney, who is based at the firm Treeline Ecological Research.

Bird deaths are currently tracked by industry employees, who report
the number of carcasses found. Using that method, the industry reported
that on average, 65 birds died each year from tailings pond exposure in
northeastern Alberta between 2000 and 2007.

"It's basically ad hoc," said Timoney, who decided to take a
different approach for the tailings ponds of Suncor, Syncrude and Shell.

started with counts of dead birds taken from formal shoreline surveys
of tailings ponds in the Athabasca tarsands region of northeastern
Alberta done in the 1980s to get an idea of deaths per square kilometre.
Those surveys remain relevant because methods of deterring bird landing
haven't changed much since then, Timoney said.

The surveys were combined with studies looking at how many birds out
of the total number that flew over actually landed and were "oiled" on
the tailings ponds.

Timoney then factored in reports of bird deaths obtained from the Alberta government through freedom-of-information legislation.

Using averages for the mortality rate of oiled birds and adjusting
for the increased size of tailings ponds over the last two decades,
Timoney came up with what he says is a more reasonable estimate for bird
deaths in the 120 square kilometres of ponds he studied.

1,973 deaths a year

14-year median, including raptors, songbirds, shorebirds and gulls, is
1,973 deaths every year, although the deaths for any given year ranged
from 458 to 5,029. That's more birds than died in the April 2008
incident that saw Syncrude convicted of charges under the Wildlife Act
earlier this year.

And the actual total is probably higher than that, said Timoney. His
study, which was funded by Dalhousie University, didn't account for
birds that landed and were oiled at night or that simply sank under the
surface of the ponds.

The total mortality is unlikely to have much overall impact on the
millions of birds from dozens of species that migrate through the
Athabasca watershed, one of the continent's main flyways.

However, Timoney pointed out, some populations, such as endangered
whooping cranes, are vulnerable to a single catastrophic event. As well,
oiled birds that escape take the contaminating materials with them to
their summer or winter habitat.

Government should monitor: researcher

Timoney said the disparity between official estimates and his results is disturbing.

"Industry-reported data on bird deaths are problematic as they are
not systematic, repeatable and statistically robust," the paper says.
"Government should assume responsibility for development of systematic
monitoring and research on tailings pond bird landing, oiling and
mortality rates."

Alberta Sustainable Resource Development Minister Mel Knight points
out that oilsands operators are required to have deterrence and
monitoring systems in place for all kinds of wildlife. But he
acknowledges there's room for improvement.

"I would not argue at all with the study with respect to the fact
that there could be better work done on monitoring, and we're going to
work to do that," he said. "At the end of the day, we'll come to
appreciate the advice that is being given to us, and we'll use it."

Alberta Premier Ed Stelmach defended his government's record on bird mortality rates.

"I stand by what we are doing. We're constantly improving, trying to
reduce bird mortality, in the oilsands, and this is with respect to our
tailing ponds," he said.

"When we get into dry tailing ponds, I'm sure that we won't have any of the same issues we have with bird mortalities today."

Timoney's is not the first independent study to question official figures on the environmental impact of the oilsands.

Last December, one report suggested hydrocarbon emissions are nearly
five times greater and twice as widespread as industry figures say.
Another suggested that tailings leakage from storage ponds is also
underestimated. A third suggested that if deforestation and wetlands
removal are considered, greenhouse gas emissions from oilsands
development are about 25 per cent higher than government and industry

Greenpeace Canada championed Timoney's study.

"Last week we learned from one of Canada's most respected scientists
that government and industry claims around toxins in the Athabasca River
are completely false. This week, we learn from Dr. Timoney, another
respected scientist, that actual bird deaths from toxic tailing lakes
are at least seven to 77 times higher and possibly substantially higher
than industry has reported," Mike Hudema, the agency's climate and
energy campaigner said in a statement.

"We can no longer let the fox guard the hen house. It has become
glaringly obvious that we can't trust the government to give us accurate
information on the [oilsands] industry."
