Historically, in our foothills there would have been a lot of oaks and sycamore that we have removed. Cavities in trees are what many species use to nest in, which we get rid of in an urban environment. So this is reintroducing a resource to the environment that would have been there historically.

LA Audubon Society Endorses Barn Owl Box Program


Los Angeles Audubon Society endorses CLAW's Barn Owl Nesting Box Program.  Read the full endorsement here

This program is an excellent opportunity to educate the public about the deadly effects of second-generation anticoagulant rodenticides on birds and to encourage nesting of a native raptor.

Enhancing The Urban Forest

The Barn Owl Nesting Box Program is part of CLAW's work to end the use of rodent poison (rodenticide) in Los Angeles and beyond. Rodenticide is extremely dangerous to the health of our urban/wildlands interface communities -- and the precious wildlife who share them with us.

How does this work? 

Just one barn owl can consume more than 3,000 rodents a year.  Barn owls are already naturally helping to control rodent populations in vineyards, farms and ranches, in California and across the world. Luckily, barn owls have a high tolerance for humans and often choose to nest in proximity to us, making perfect neighbors even in an urban setting--such as the barn owl populations already living right here in Los Angeles. 

About Barn Owls

  • Barn owls are one of three species of owls native to Los Angeles.   
  • Barn owls are a permanent source of rodent control without pesticides or chemicals.
  • The largest prey a barn owl can take is a rodent so they are no threat to pets. 
  • The more barn owl boxes we place in a community, the greater the odds the owls will find and use them - second and third generation owls will return to these nesting cavities.
  • Barn owls can lay two clutches a year.

Become A Barn Owl Host

  • Our boxes are paid for by tax-deductible donations. If you choose to donate the entire cost of a nesting box ($200.00 or more), we will promptly begin the process of getting you your box.
  • We ask you to visit ten of your neighbors to ask them not to use poisons of any kind for rodent control. Your own neighborhood must be poison free for at least three months before a box can be placed. This will prevent your owl from succumbing to secondary rodenticide poisoning.  Download Barn Owl Box Program flyers to share with your neighbors.
  • Once the three-month poison-free period has passed, your nesting box can be installed. We will provide you with mounting instructions. You may choose to mount it yourself or through the services of a CLAW endorsed expert.




  • You will need to clean the box once a year or have a professional do the cleaning. 
  • You may be asked to monitor the box once a family of owls takes up residence for a nesting season, which can take place up to twice a year. The rest of the year, the owls stay in the area but don't need the box. 



Owls alone won't solve your rodent problem but please don't use poison.  Use traditional rat traps or electric zappers and hire an abatement specialist rather than an exterminator.  For more abatement practices and alternate solutions, click here.  

CLAW would like our neighborhoods to join in creating an environment where these birds can thrive.  We have already begun delivering boxes to Laurel Canyon and Pacific Palisades and hope to come to your community soon.
