Protecting Pelicans from Deadly Downdrafts

Winter evenings, when north winds blow, brown pelicans perish along SH 48 between Brownsville and South Padre. The highway bridge, concrete barriers, and changing tides, contribute to downdrafts that cause the birds to crash onto the roadway enroute to their roost at Bahia Grande.

It’s heartbreaking to see what’s going on there.

Over the last year more than a hundred the birds died on SH 48. Texas Parks and Wildlife Department, TxDOT, USFWS, nonprofits and citizen groups, have joined to develop solutions, says Laura Zebehazy, program leader for Wildlife Habitat Assessment at Texas Parks and Wildlife.

They’re putting up temporary signage to ask the traveling public to slow down. Be aware: there’s pelicans on the road. DPS is getting involved. There’s folks who volunteer to flag people down to get them to slow down if they know a bird is on the roadway.

Earlier, TxDOT installed poles on the bridge, which forces the birds to fly higher.

Now, they’re actually putting these flashing lights [on the poles] so the birds can see. All of these things trying to encourage the birds to move up as much as possible so, they can maybe avoid that tornado of winds that makes them fall to the roadway.

If you find yourself driving that stretch of road at dusk this winter, slow down; save lives.

The Problem With Pelicans

You’re driving the posted 75 MPH speed limit on SH 48 in south Texas. It’s winter. Dusk. You’re crossing the bridge. Suddenly, you see a pelican on the road; you barely miss it.

What happened?

In winter, what’s been happening at the Gamin Bridge—at SH 48 in Bahia Grande—is strong northerly winds come through at dusk, when pelicans are coming from the coast; they want to go roost on the Bahia Grande, [but] the way the bridge as well as the concrete barriers is engineered, it’s creating these wind vortexes that—if they don’t get high enough loft—makes the birds lose loft, and they crash into the roadway.

Laura Zebehazy, program leader for Wildlife Habitat Assessment, studies the impacts of roadways on wildlife, known as road ecology. Researchers believe the structure of the SH 48 Bridge, along with the fluctuating tide, may impact the wind, and the pelicans’ fate.

It is contributing, but now there needs to be further research that looks at what can we do to the bridge and those concrete barriers that’s the most effective to alleviate the number of pelicans that are being impacted.

We’ll learn more about that tomorrow.

Road Ecology and Protecting Rare Species

Roads provide convenient travel to work, school and home for humans—but not for wildlife.

You have habitat loss. And then that physical road can act as a barrier to wildlife. It can impact habitat connectivity. Which, then, in turn can impact genetic transfer of information between populations, and weaken the genetic background for a species.

Laura Zebehazy, program leader for Wildlife Habitat Assessment, studies the impacts of roadways on wildlife, known as road ecology.

Basically, it is where biologists, engineers, landscape architects… try to evaluate the impacts that road infrastructure has on wildlife habitat connectivity, air pollution, noise pollution, and try to find solutions to alleviate those impacts from that type of development.

Endangered ocelots that live in Rio Grande Valley brush country have died on SH 100. Recently, TxDOT, in consultation with USFWS and Texas Parks and Wildlife…, completed four wildlife underpasses along this popular route to South Padre Island.

To allow ocelot and any other wildlife in the area to move under the road between the Bahia Grande to the south, and the Port of Brownsville area up north towards Laguna Atascosa National Wildlife Refuge.

With wildlife cameras in place, TxDOT will collect data on these solutions and adjust as necessary to save this (and other) rare species.

Solution to Woodpecker Damage to Home

Pileated Woodpecker

Pileated Woodpecker

This is Passport to Texas

As a rule, woodpeckers dig out cavities in dead trees, called snags. Once construction is done—they move in. The exception occurs when they mistake your home’s wood siding, for a snag. When they do—homeowners have problems.

And it looks like cannon balls have been shot through the house. Maybe two or three; and we’ve seen some with fifteen, sixteen holes.

Cliff Shackelford is a non-game ornithologist with TPW. He says woodpecker damage occurs most often in urban and suburban areas where homeowners have removed the dead trees from their property.

What we recommend people to do with problems with woodpeckers is to put a nest box. If you’re familiar with a bluebird box, it’s just a larger version of that custom made for woodpeckers.

Find information and free blueprints to make your own woodpecker nest box at passporttotexas.org.

People can build this in a couple of hours on the weekend, and put it up on the side of the house, and in all cases that we’ve done this – it’s worked. And the woodpecker stops chiseling on the home, and goes to this next box, and is very content.

Don’t Blame the Termites for this Damage

If you live in East Texas, and have noticed strange holes in the wood siding of your home, don’t panic and call the police—call an ornithologist.

There are fifteen species of woodpeckers in Texas, eight of which are in the eastern third of Texas. And that’s where we get most of our calls of woodpecker damage.

Non-game ornithologist, Cliff Shackelford, says the pileated and red bellied woodpeckers are among the feathered culprits inflicting damage on homes with wood siding.

What happens a lot of time is that they see these houses that might be painted brown, they might have cedar siding, and this is very attractive to the birds to try to excavate a cavity. So, they’re not looking for food when they’re doing this; they’re looking to make a cavity to call home.

The pileated woodpecker, about the size of a crow, can excavate holes as big as a man’s fist—and not just in the outside walls of your home, either.

That’s right. We’ve documented pileateds going through into the sheetrock and into the room of the house. Of course, they’re very lost when they do that, they quickly go out. They’re not looking to make a mess of the house.

But they do. How to keep woodpeckers from damaging your home…that’s tomorrow.
