A friend passed along a news article about a Barred Owl of Central Park that was likely poisoned when it ate a poisoned rat.
Here's the first paragraph:
"Barry, the beloved barred owl who died last month in Central Park in a collision with a truck, carried a potentially lethal level of rat poison that could have impaired her flying, a necropsy shows."
Then, two paragraphs later:
"... veterinarians who performed the necropsy also found high levels of rat poison in Barry’s bloodstream, putting her at risk for a “fatal hemorrhage” even without the collision, the report found. The vets also detected traces of a rat and fish scales inside her more than 2-pound body."
The two poisons -- bromadiolone and difethialone -- and similar poisons are often used in the 70-plus rat-poison bait stations that abound in Allendale. The Borough Council recently passed a resolution urging businesses to stop using these lethal devices.
A typical rat-poison bait station is pictured below. They also impact other wildlife and pets that eat poisoned rodents.
