TPW TV – Owls Underground

Burrowing Owl

Hey! Outta my burrow, you skunk!

This is Passport to Texas

Birds don’t get much cuter than the burrowing owl. And you won’t have to stay up past your bedtime to see one.

One of the great things about these owls is [unlike most owls] they’re out during the day; they’re active day and night.

The week of July 31, get to know this small sandy colored owl with long legs during a segment of the Texas Parks and Wildlife TV series on PBS. Alan Fisher produced a story that looks at how this species, threatened and endangered in some part of North America, survives its dwindling habitat in El Paso.

So, they’re a species of concern here because of habitat loss. Burrowing owls don’t tend to dig their own burrows from scratch. They will occupy burrows left from prairie dogs or ground squirrels or other burrowing animals. So, as those animals get pushed out burrowing owls lose their habitat as well.

Fisher also talks with Texas Parks and Wildlife biologist Lois Balin, who creates artificial owl nest borrows fitted with video surveillance systems.

Having the cameras underground, gives the biologists a lot of new tools. It’s pretty awesome.

Not surprisingly, says Fisher, the cameras are revealing much about the hidden lives of burrowing owls, from the number of eggs and nestlings, to prey items, and even visitors.

The skunk discovery is the rather astonishing discovery. Skunks are going into the burrows and occupying them, and in some cases preying on the owls.

To find out how the burrowing owls fare, tune into the Texas Parks and Wildlife TV series on PBS the week of July 31. Check your local listings.

Owl Nest Boxes

What would you call a wooden box intended for owls?

02- It would be called an owl box.

I really need to start making these questions harder. Ornithologist, Cliff Shackelford says man-made owl boxes are a “stand in” for what nature provides.

07-What these owls would do is look for a cavity in a tree–a hollow in a tree–and that’s what this box is replacing.

The Barn Owl and Eastern Screech Owl are two wide-ranging owl species in Texas, with different needs.

15- They use different size boxes. The Barn Owl is much larger than the Eastern Screech Owl. And you can go online on the Parks and Wildlife website; we have blueprints on how to make these boxes for these birds. Or you can just go online [to other sites] and find other blueprints and make them [the nest boxes] to your
liking.

Owls make some people nervous because they are raptors and have strong hooked beaks and sharp talons, but Cliff Shackelford says, fear not.

14-The good thing about owls: they’re good neighbors to have because they eat a lot of rodents. Screech Owls eat a lot of roaches. The wood roaches. The big ones that are outside. So, it’s good to have owls, because they’re keeping these things that we consider pests in check.

Cliff says owl boxes work best in areas where you have good tree cover. I have a link where you can find the measurements for nest boxes and bird houses
appropriate for common species at passporttotexas.org.
