An owl kills its prey by driving its razor-sharp talons in deeply. The prey (usually a field mouse, rat, snake or squirrel) then dies quickly from a punctured (whatever it is). The pressure a Great-horned Owl or Barred Owl (both seen in north Texas) exerts with its talons is a phenomenal 250 pounds per square inch (“psi”). Compare that to the pressure I (an ordinary male) can squeeze with – around 80 psi. Maybe 90 if I’ve had a good breakfast.
However, YOU could kill an owl just by using a poisonous/chemical rodent killer. Many brands of rodent poison aren’t finished when they kill a rodent; any creature that eats the rodent’s carcass (often an owl) is poisoned too. That’s a shame since an owl may kill and eat dozens of pests per day – at no cost or danger to you.
