Most residential and rural dwellers don鈥檛 enjoy rats, mice and ground squirrels setting up shop on their property, so they often resort to poisons to control the rodent populations. While those products succeed in getting the job done, they can also be deadly for birds that prey on rodents.
When a rodent eats a poison such as a second-generation rodenticide, it can still survive for several days before it succumbs. In its compromised state, the rodent becomes even more vulnerable to sharp-eyed raptors like barn owls. The owl eats the poisoned rodent and in short order becomes poisoned itself, leading to debilitating illness or death. Hibbert Lumber in Davis, CA, who donated the wood used in this video, in 2015 after they removed second-generation rodenticides from their store shelves completely. To see that happen on a large scale, the organization has been working with consumers and policy makers.
An owl box is a great alternative to poisons because it draws barn owls into your neighborhood and puts them in charge of your pest control. Not only are you not harming raptors; you鈥檙e actively supplying them food!
The box is divided into two chambers so that babies can be nurtured on one side without risk of falling out of the tree. The other side has an entry/exit hole for the grown owl. There鈥檚 a hatch on the babies鈥 side so that the box can be cleaned out during the season when owls are least likely to be there 鈥 usually around October and November in Northern California, where the swag外流 School of Veterinary Medicine鈥檚 is located.
Build your own owl box! Just follow the steps in the video above.
