Finding the Wily, Wild Houston Toad!

While many of us are enjoying these cool, winter evenings indoors in front of the TV with our favorite snack, Houston toad researchers are bundling up, grabbing a thermos of coffee and hitting the road to find the  elusive Houston toad! After the first heavy rain of the year, often near the end of January, Houston toads are hitting the ponds to look for mates.  The Houston toad spends the majority of the year in shallow burrows to escape the extreme Texas temperatures (a process called estivation); therefore the best opportunity to find and count toads is during their breeding season when they are out and about.

Though some toad biologists slip on a pair of rubber boots and put on a headlamp to look for Houston toads using sight, most researchers search for toads using sound. Sound? How does that work? The Houston toad males have a very distinctive advertisement call, which is the call that they use to tell female toads “Hey, lady! Check me out! I’m over here!” In fact, all species of frogs and toads have a distinctive call that they use to get the attention of the opposite sex. Interestingly, it is not just the males that do the calling. In some species, including another local frog species called the gray tree frog (Hyla versicolor), the females will both call and counter-call (which means to call back) to the males.

To find calling toads, researchers set out in their cars after dark to literally “listen” for Houston toads. The areas that are visited have been previously identified as suitable habitat for the Houston toad, or are locations where Houston toads were either found or heard in the past. The surveys follow a very systematic pattern with dozens of stops, and they often take hours to complete. This year, for the first time in several years, five Houston toad counties are being surveyed at once lead by research teams from Texas State University and USFWS. Fingers crossed that we’re going to find some wild toads!

Another way that researchers find wild Houston toads is through the use of a recording device called a SongMeter. A SongMeter is specifically designed to detect the auditory calls of wild animals.  To detect Houston toads, SongMeters are placed in trees near ponds and are programmed to record sounds during the course of the night. These devices can record two weeks’ worth of sound data! A software program is then used to find the particular waveform that correlates to the Houston toad call. Of course, every Houston toad “hit” found by the software program has to be verified by human ears, which requires hours of listening time.

So over the next couple of months while you’re enjoying your favorite evening TV show, take a moment to think about the field researchers braving the chilly, wet Texas nights on the hunt for the Houston toad. Each toad found (or heard) tells us more about the health of the wild population and gives us another critical piece of information concerning the natural history of this rare species. Good luck toad folks and Godspeed!

This morning, we humanely euthanized our male, 20-year-old jaguar, Kan Balam. Due to the tremendous care provided to him by his keepers and our veterinary team, Kan Balam lived well beyond his expected lifespan. Jaguars expected lifespan in the wild is between 12-15 years.

The carnivore staff and veterinary team made the decision after his quality of life began to decline. Quality care and continuous advances in veterinary medicine extends animals’ lives longer than ever, with most felines in human care living well beyond previous generations. Because of this, all cats, including domestic house cats and jaguars, often spend a significant phase of their lives as older animals, and are at a higher risk for geriatric complications.

Soft kitty, warm kitty, little ball of fur; happy kitty, sleepy kitty, purr purr purr #RIP #bigbangtheory

I know he lived a lot longer due to the excellent care he got at the Zoo.

Is this the one that had the limp?

This was my daughters favorite critter at the Zoo. We always went to say hello to him before anyone else whenever we went. When she was 7 years old we sent a post out to out neighborhood on Halloween saying Paisley was asking for pocket change donations in lieu of candy for Halloween and all amounts would be donated to Kan thru the zoo. She raised over $40 in coins! I still have the letter from the zoo thanking her for her donation. He was a sweet boy and will be missed. 😔

I saw him limping about 2 weekends ago. The first time we walked by he was fine. When we walked by on the way out he was limping and moaning pretty loudly. I wondered what happened but I figured his keeper already knew or would find out shortly. Super Sad. He was always a lively one.

Sorry to hear about your loss. We also lost a jaguar(melanistic variety) at Reid Park Zoo about a year ago. Nikita was 21 years old and was euthanized due to health-related issues. Sad, but they have a GOOD life at the zoo! No predators, a steady food supply, medical attention, loving kindness from her keeper(s) and admiration by the public. Geriatric animals have unique problems and we are blessed to get to know them as long as we do.

Jaguar habitat is in the Zoo or Jungle's? ??or is only entertainments for person's? ??$$$$$$$!.Sorry animals the person's don't love you ..

Thank you Houston Zoo for taking such good care of him and all the animals! I've been going to this zoo since I was little bitty. I always enjoy it.

Dunno if the Zoo staff considered him a pet but he was certainly a family member, and because of that i offer this: RainbowBridge Author Unknown Just this side of heaven is a place called Rainbow Bridge. When an animal dies that has been especially close to someone here, that pet goes to Rainbow Bridge. There are meadows and hills for all of our special friends so they can run and play together. There is plenty of food, water and sunshine, and our friends are warm and comfortable. All the animals who had been ill and old are restored to health and vigor. Those who were hurt or maimed are made whole and strong again, just as we remember them in our dreams of days and times gone by. The animals are happy and content, except for one small thing; they each miss someone very special to them, who had to be left behind. They all run and play together, but the day comes when one suddenly stops and looks into the distance. His bright eyes are intent. His eager body quivers. Suddenly he begins to run from the group, flying over the green grass, his legs carrying him faster and faster. You have been spotted, and when you and your special friend finally meet, you cling together in joyous reunion, never to be parted again. The happy kisses rain upon your face; your hands again caress the beloved head, and you look once more into the trusting eyes of your pet, so long gone from your life but never absent from your heart. Then you cross Rainbow Bridge together....

Aww. When interning in the carnivore dept he was one of my faves. So smart! Ashley remember when Angie was teaching him to do the moonwalk after Michael Jackson passed?

Sending love to the keepers that are broken hearted right now. And thank you for all the care you’ve given.

Beautiful jaguar ....so grateful for the Houston Zoo keepers and veterinary team that gave their time and efforts to share this awesome jaguar with us for so many years.

He was well-cared for and most of all well-loved. My heartfelt condolences to those missing Kan B as well as me. What an amazing ambassador for his kind. What a beautiful old gentleman. Thank you for loving him into old age and giving him peace.

What a great long life he lived because of his excellent care at the zoo Thoughts go out to his keepers and the entire Houston Zoo staff

Thank you for doing what was right and kind for Kan Balam even though it was hard and painful for you. That’s true love for an animal. ❤️

RIP Kan Balam. You have given the visitors so much pleasure just watching you over these years. You were taken care of by top notch professional handlers, etc.

I'm so sorry for your loss. Thanks for taking such great care of him so he was able to live a long life. My thoughts are with his keepers and all who adored him. <3

Aww I’m so sorry for the loss, I’ve seen him many times, he was absolutely gorgeous! I’m glad that you guys were able to make him comfortable, sometimes the best thing we can do is let them be at peace. Will miss this handsome guy; play hard at the Rainbow Bridge friend, day hi to my cat, Junior for me!! Much love to the HZI staff!!

Jaguars are one of my favorite and he seems like a sweet boy. I'm so sad but I'm happy he can be painless and be free now. RIP❤️

The Houston Zoo staff has lost several animals this year and I am sure each one is so hard to go through.

I am soo sorry for the loss of this handsome fella Kan Balam. May he rest in peace and run free or any pain over the rainbow bridge.. My heart and prayers go out to each and every one of the staff at the Zoo.

Katie Rose Buckley-Jones I won’t ever forget the time you asked him to bring something and he ripped off a piece of cardboard and tried to hand it to you ❤️ thank you for introducing me to him. Sending you guys many hugs

So sorry to the keeping staff for your loss i cant imagine how youre feeling :( his old age is a testimony to the amazing care he received

I will miss him. The last time I saw him he looked tired, and it appeared his foot was bothering him.

Sad to hear of this. Thanks for taking such good and compassionate care for him and the other animals.
