This Barn Owl could hear my heart beating.
The Barn Owl has excellent low-light vision, but its ability to locate prey by sound alone is the best of any animal that has ever been tested. It can catch mice in complete darkness in the lab, or hidden by vegetation or snow out in the real world.
A barn owl will eat at least 10,000 rodents a year. For every owl that dies prematurely from poisoned rodents, 10,000 extra rodents are free to multiply.
If we don’t want the rat population to explode we must STOP USING RAT POISONS.
All poisons kill the predators as well as the “so called pest.” In the long run your problem becomes harder to manage.
The food chain if allowed to thrive will keep the balance.
As we always say, “No Poison Is Safe.”
