We need more owls around here

     North Texans are often surprised to learn that they have owls as neighbors. It's true, but there are fewer owls around than a decade ago. Our common owls range from the ±10” Screech Owl, through the mid-sized Barn Owl, to the large Great-horned Owl.

Barn Owl

Owls hunt at night, and feed on animals also active at night, including large insects and many species of rodents. An owl is one of the best rodent-control creatures on earth. One adult Barn Owl eats about 90g. of food a night – the equivalent of two rats.  A breeding pair and their chicks can eat about 3000 rats per year. Where rodents have been displaced by recent construction, owls (particularly Barn Owls) eat well.

     Unfortunately, the large, dead trees they like to nest in are frequently cut down and natural tree cavities are filled in, so good nesting sites can be hard to find.  Man-made nest boxes can help alleviate the problem. They can be put almost anywhere – even on the wall of a house. It should be in shade most of the day and, especially in Texas, shouldn’t face the hot, west sun.

Believe it or not I've been asked if owl droppings (“pellets”) carry disease. These are the undigestible bits and pieces of its prey, such as bones. According to the CDC, they transmit no known disease. Consequently there is no health reason for any preventive sanitation.

There's no 100% sure way to attract owls to your yard. Providing a good habitat, nest material and a nesting place are the best things you can do.
Since owls fly quietly at night, you may never know that they’re around, so they’re very good neighbors.
