There are many possible causes of owl mortality besides rodenticides.
Testing a fresh owl carcass for cause of death can be quite expensive. For
example, the Animal Diagnostics Lab at LSU charges $169 for a necropsy,
plus accession and shipping fees. Want to test for anticoagulant
rodenticides? $67. Want to look for the neurotoxic rodenticide Bromethalin?
$34. How about West Nile Virus? $53. Avian influenza? $46. Etc. As you
can see, costs mount quickly, which explains the scarcity of tested
Regarding anticoagulant rodenticides (AR), we at Urban Raptor
Conservancy are collaborating with PAWS Wildlife Center on the first
systematic study in raptors in Washington State. We are testing recently
dead hawks and owls for AR exposure. This is an expensive study. We are
applying for grants and gratefully accept private donations as well. For
