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.

The Christmas Tree in Texas

The custom of decorating trees for Christmas took root in German villages during the sixteenth century.

A lot of Germans, as you know, settled Texas. And they brought a tradition with them of the tabletop Christmas tree.

Cynthia Brandimarte is program director for Texas historic sites.

When you look at interior photographs of Texas houses, you see many tabletop Christmas trees ornamented for the season, particularly in German households in the late nineteenth century Texas.

Ornaments were handmade then, and small gifts often dangled from branches. Eventually, the tabletop conifer gave way to larger trees that became “floor models,” and the decorations sometimes mirrored the day’s events.

You saw more and more seven or eight feet trees that were placed on the floor. And because we had just ended the Spanish American war in victory, there was a fashion in the early part of the twentieth century to decorate trees with a few American flags here and there. We have photographic evidence for that.

If you celebrate Christmas, we wish you a joyous holiday season. And if you do not, then it’s the perfect time to immerse yourself in nature, because Life’s Better Outside.

Quail and Turkey Outlook for 2017-2018

Last quail season, bobwhite were at an all-time high thanks to a few years of great weather in a row.

We saw something we hadn’t seen in over 10 years, and it was quite special. And what comes up, must come down.

Robert Perez is Upland Bird Game Program Leader.

This past winter and spring we had average winter rains. Average spring rains. And so, we did have some quail production over the summer—that wasn’t phenomenal. But what we did have was so many birds that are still alive from last year that they carried over to this year. So, hunters can expect—in the bag—a lot of adult birds.

The season for Bobwhite, Scaled (blue) and Gambel’s Quail runs through February 25, statewide.

Scaled quail were phenomenal as well. Way out west in the Trans Pecos. There will still be great hunting opportunities out west at our WMAs.

If turkey’s more your bag, Perez says Rio Grande Turkey season is looking good.

Rio Grande turkey hunting in Texas is top notch. Populations in our state are at an all-time high. We’ll have two year old, three year old birds. Maybe not so much production this past year—a little bit below average—but, overall, Texas populations of Rio Grande turkeys are just through the roof.

Refer to the Outdoor Annual for seasons and bag limits for all upland game birds.
