“It’s working time,” Hindmarch says as she grabs the first mouse in its transport cage and scoots it through the open door of a small cage that’s part of the owl trap. The first of these, synthesized in the 1940s, is known as warfarin – the same chemical sold in miniscule concentrations to people as Coumadin, a prescription blood thinner. The chemicals in question are known as anti-coagulants because they prevent an animal’s blood from clotting or coagulating.

We’re surprised that there’s that much of the stuff kicking around.” “There’s a lot more rodenticide in the food chain than we would have ever thought. “We’re finding this stuff all over the place,” said John Elliott, an Environment Canada scientist who co-authored the owl study published last year. The study is the latest evidence that poses an unsettling question: Are we willing to poison owls and a variety of other wild animals in order to fight rats? Pesticide readings in 15 percent to 30 percent of the others appeared toxic and seem likely to handicap owls in a variety of ways, scientists say. Six of 164 dead barn owls, barred owls and great horned owls examined in a 2009 western Canada study funded by Environment Canada had rodenticide levels high enough to kill them outright, causing fatal stomach hemorrhages. The culprit: An extra-potent class of rat poisons that has flooded the market in recent decades, designed to more effectively kill rats, a food source for the owls. Scientists know that at least some owls are dying under gruesome circumstances, bleeding to death from stomach hemorrhages in an agonizing and days-long decline. Their mission is to determine whether the decline of Canada’s barn owl is tied, in part, to super-toxic rat poisons.

Working in darkness, with the quarter-moon obscured by clouds, these two scientists are trying to figure out what an elusive, radio-collared owl is eating along this country road just beyond the suburbs that ring Vancouver. Then a few seconds later, dejected, he radios back: “No. “Are you getting anything?” research team leader Sofi Hindmarch asks over a walkie-talkie. The first rodents to die from this poison are usually found 4 or 5 days later.With the spooky glow of his headlamp illuminating an antenna in his hand, Paul Levesque stalks one of Canada’s few remaining barn owls.
