A lot of us, when tracking wildlife, search for footprints only.

You know, the tracks, themselves, are the easy part as far as determining something’s been there.

East Texas wildlife biologist, Heidi Baily says the tracks alone tell only part of the story.

In my experience, one of the toughest things for a tracker to learn, is to just take a step back and look at the scene as a whole rather than zooming in on one or two tracks. Sometimes it really helps to step back and look at where the animal’s been going, and what he’s been doing. You get a whole lot bigger picture as opposed to just kind of a snapshot and being able to say, ‘Okay. That’s a raccoon.’

Heidi says when people start opening themselves to fully tracking wildlife—and not just the footprints—they begin to experience the outdoors in new ways.

A lot of times, you may not see wildlife, but tracking just puts it in your mind that you’re surrounded by wildlife whether you see it or not. And, it really gets your brain to churning trying to put yourself in the mind of that animal. It’s a real treat, and a good time to get outside and enjoy it to the fullest.

Wildlife Tracking

When it comes to wildlife, there’s more of it out there than meets the eye.

Some of them are fairly secretive. A lot of times, we never even see the animal. Looking at the tracks and sign are the only way that we’re able to determine that the animals are present.

Heidi Baily is a wildlife biologist in east Texas. She says tracking is a skill she uses when conducting wildlife surveys.

Wildlife tracking is getting out there and looking for not just the tracks or the imprints left by the feet of the animal, but it’s also getting out there and looking for chew marks on a particular plant. Or, maybe scat—which is the highfalutin name for animal poop. Or a feeding sign, or anything that reveals that something has passed through.

When tracking wildlife, Heidi says, it helps to think like the animal you’re tracking.

The best trackers are the ones who can put themselves in the mind of the animal, and be able to determine where it’s been, what it’s doing and where it’s going. That’s the fun part of the wildlife CSI of it: almost becoming the animal.

Tracking isn’t for wildlife biologists only. Heidi Baily says anyone can track wildlife, starting in their own backyard. Find field guide and tracking app information at

Vulture Fun Facts

This is Passport to Texas

Vultures get a bad rap: maybe it’s because they aren’t “pretty birds”, or because they eat road kill. Non-game Ornithologist, Cliff Shackelford, says they deserve our respect as they are a helpful, interesting species.

Vultures have a role to play, what we call ‘ecosystem services’. These are benefits to us; it’s unfortunate that our cars hit animals—but think about what’s left behind. The vultures are cleaning up all the mess and we have to commend them for that.

How do vultures eat decaying carcasses and not get sick?

Vultures don’t get sick because they have certain bacteria and other flora in their guts that help them break down these carcasses.

Although a migratory species, vultures live year-round in Texas. When road kill freezes up north, those vultures travel south.

Because of our location, we not only host a lot more vultures in the winter season, we see a lot more passing through in the spring and fall migration.

Vultures are social birds and roost together, preferring the tall structures that allow an easy entrance and exit.

They like cell phone towers, rocky outcrops and ridges, an old tree that’s standing up really high. They like the tallest roof in the area.

Yet, they nest on the ground under fallen trees, and are excellent parents. Now that you’re better acquainted, we hope you’ll give vultures a little respect.

Some people call them buzzards, but Cliff Shackelford says the correct ornithological name for the large black birds that dine on road kill is: vulture.

We have the turkey vulture and the black vulture.

Shackelford is a non-game ornithologist with Texas Parks and Wildlife.

And the best way to tell them apart when they’re perched and sitting on that dead deer carcass on the roadside, is: look at the color of the head on the adults. The black vulture has a gray head and the turkey vulture, a red head.

Vultures circle high above the land in search of a meal.

The turkey vulture uses the sense of smell, and they’ll smell their prey. The black vulture, though, uses sight, they’ll look for prey, but they’ll also cheat. They’ll also look for where the turkey vultures are circling—[and decide] I’m going to bump in line. And with their numbers, usually the black vulture can overcome the turkey vulture and get the first little bites.

More fun facts: vultures poop on their legs to cool off, and when threatened, they vomit.

This is a defensive mechanism. They don’t have fangs like a rattlesnake; they don’t have claws like a bobcat. So, their best defense is to throw up what’s in their stomach that was lying on the road for the last three days. And guess what? You’re going to turn away; it’s a great defense.

How to Behave Around Alligators

With more alligators spotted by the public in residential areas, you might think you’d be better off selling your home. The fact is… there’s no need to panic if and when you see a gator in your neighborhood.

We’re just trying to help people put it in perspective. People will begin to see more and more alligators in the future and not every alligator is going to be a problem.

Greg Creacy is a wildlife biologist based in Bastrop. He says horror movies and attacks by the more dangerous, and non-native crocodiles have caused people to be afraid of Texas alligators.

The number of attacks by alligators in the US each year is less than injuries and fatalities from dogs, scorpions, snakes and sharks…all of those are much more dangerous to people than alligators.

So what do you do if you see an alligator? Keep a safe distance from them and keep pets away from them. Don’t swim in an area where there are alligators…and don’t feed them.

Because people have fed that alligator they’ve broken down their natural fear that alligator has for people.

Find more information on living with alligators on the Texas Parks and Wildlife Website.
