Recycle your old string lights at the Dallas Zoo, and help protect wildlife this holiday season

Reduce your impact this holiday season by recycling your old string lights!

Collection bin is located at the Zoo’s front entrance throughout Dallas Zoo Lights and will remain until January 13.

Are you tangled up in holiday lights? Don’t know what to do or where to turn? Fear not! Bring us your old string lights, and we’ll keep them out of landfills by recycling them responsibly. Many string lights are made with copper and other precious metals, which are harvested through mining in places like the Democratic Republic of the Congo where critically endangered gorillas and okapi live. Recycling these metals reduces the need to mine for new materials, which causes animal habitat destruction and other harmful effects to our environment.

There are so many reasons to recycle, but here are a just few ways that recycling benefits the environment and will help us Create a Better World for Animals:

  • Less waste sent to landfills provides more habitat space for wildlife.
  • Reduces the risk of waste making its way into places it shouldn’t, like the ocean, where animals can accidentally ingest it or become tangled.
  • Allows us to reuse materials without having to harvest new ones, including copper and plastics.
  • It takes less energy to recycle materials than to create new ones.

What do we do with these old lights? They go to our trusted metal recycler where they’re broken down and the parts are recycled individually.

 *Only string lights will be accepted for recycling; please do not bring other items like flood lights, extension cords or light hooks.

Heeding the call: Earthwatch expedition to save chimpanzees

Cristina P. in Uganda on her Earthwatch expedition to BCFS.

Primate keeper Cristina P. guest blogs on ZooHoo!

In August of 2016 I received an unexpected call from the Dallas Zoo’s HR director. She informed me that I had been selected as one of the finalists for an Earthwatch Fellowship, and 9 months later I was on my way to an adventure I will never forget.

Our group met up at a hotel in Entebbe, a city on the Northern Shores of Lake Victoria, 23 miles from the national capital Kampala, Uganda. We had only 5 participants in our team – 3 from Australia, one from Switzerland, and myself. Being in a small group allowed us to really form personal connections, and I am so grateful to have had the opportunity to meet people from around the world, including the great people of Uganda.

Chimps gathered near our cabin in the forest.

We left for the Budongo Conservation Field Station (BCFS), and 6 hours later we arrived to the most remote location I had ever been. The nearest town was 45 minutes away, I was not going to be in communication with anyone via phone or internet for the next 10 days, and primates were my new neighbors. I could not have been more excited.

We were surrounded by groups of blue monkeys, red-tailed monkeys (also called guenons), baboons and black and white colobus. We saw many bushbucks (a brownish-red hoofed stock) as well as a few genets and civets at night. We heard the nightly calls of the tree hyrax.  Birds were abundant in the area making it a great spot for bird watchers. The butterflies were the prettiest I had ever seen.

BCFS has been around since 1990, and over the years, researchers have noticed that some of the fruit trees (which provide the chimps’ natural food source) have been producing drastically fewer amounts of fruit. The local villagers also believe that chimps and baboons have been raiding their crops more frequently. Could the decline of fruit availability be causing the increase in crop raiding? Could the fruit decrease be caused by global warming? Is this simply part of a natural cycle of the forest? The area had been exploited for many decades by the British for mahogany, so there’s also a theory that maybe as the forest regenerates and trees get taller, there is less sun getting through to the shorter fruit trees, thus affecting their development.

BCFS tries to look at every piece of the puzzle, so many of the tasks we performed were for the purpose of furthering this research. One day we set up mist nets in the forest to catch birds and catalog them, since they are important in spreading seeds (they were released after we were done with measurements, banding and pictures). BCFS field assistants monitor types of leaves and fruit levels on around 1,400 fruit trees in the area, so we assisted in data collection for that project as well.  But most importantly, we observed 2 troops of chimpanzees, which was an experience like no other.

We observed this chimp enjoying a snack.

Some days, we’d start walking before dawn so we could find the chimps as they were waking up. One of the groups, called Sonso has been studied since the beginning of the project and is fully habituated, which means they see the people as part of their environment and do not mind human presence. The second group, Waibira, has been studied since 2011 and are still in the process of habituation. For the purposes of minimizing disease transmission and our safety we were told to keep a distance of approximately 23 feet to the chimps. The only problem with that was the animals don’t know that rule and at times came pretty close to us. It was fascinating to be so close to an animal that is so strong and powerful, yet they seemed to just go about their day as if we weren’t even there.

A chimp is observed with injuries from being caught in a snare.

We also had the chance to assist the snare removal team. In this particular area, chimps are not hunted for bush meat. Instead the targets are bush pigs, blue and red duikers, and bushbucks. Unfortunately though, chimps inadvertently get caught in those, and about 25% of the animals in this area have a snare-related injury. One particular female had gotten caught by a snare 3 different times! They have even been observed trying to free one another from the snares. It was also noted that there was no difference in how the injured chimps were treated by their troop and they seem to eventually adapt to their new reality of missing fingers, toes, etc. Unfortunately some are not so lucky and do end up dying from their injuries. Occasionally the BCFS veterinary team will sedate an injured chimp and remove a snare if the animal is left behind by its troop.

On one of our last days we visited a nearby village to interview the local farmers and learn about the impact that chimps, baboons, and small monkeys have on their crops. Years ago, BCFS helped them identify what kinds of foods would be least appealing to the animals and provided them with seeds, which were then planted near the forest edge. They do this in the hopes that the animals might keep walking further out to search for foods they like better. The farmers depend on these crops, not only for income, but also to feed their families.

Leaving BCFS was bittersweet. I still miss seeing the chimps and all the people I met! But since I’ve returned from Uganda, I have a renewed hope that there are people out there doing amazing things every day to save these animals from extinction.

World Gorilla Day: Celebrating gorillas by celebrating our littlest one

Baby Saambili’s has grown so much since her birth on June 25, 2018!

World Gorilla Day marks the 16th anniversary of the Dian Fossey Gorilla Fund International’s Karisoke Research Center, which is the longest running field site dedicated to gorilla research and conservation.

In honor of this special day, we sat down with Assistant Great Ape Supervisor Tamara Jochem to talk about how much baby Saambili has grown since her birth on June 25, 2018.

Today is not only about celebrating these magnificent animals – we are also reminded of the very serious threats they face in the wild. YOU can make a difference! Read on to get the inside scoop on all things Saambili and learn a few simple actions you can take to help support gorillas conservation efforts everyday.

How much has Saambili grown and changed physically since she was born?
We don’t know exact numbers because she’s with mom 24/7. But she has a lot of extra skin that she’s ready to grow into. She also has a little belly and lots of muscles in her arms and legs. She’s a stout little thing! And her teeth started coming in about a month ago. We think she’s got about six teeth on the bottom and four on the top, so far.

Will she go through teething, like a human baby?
Yep, she will. She’s handling that pretty well, based on our observations. She will chew on her fingers, or anything she can fit in her mouth – lettuce, kale, broccoli – and she might get a bit fussy from time to time.

Hope supports Saambili’s bottom while walking on her knuckles.

Tell us about the relationship between Hope and Saambili.
Gorilla babies are born already able to cling, so she’s been able to hold onto Hope’s hair since the beginning. Hope is a very attentive mother, so most of the time she is either supporting or holding on to her baby. She has started to put Saambili’s bottom in her hand, and Hope will walk around on her knuckles. Within the next month or two, we will probably start seeing Saambili start to ride on Mom’s back. Saambili needs a little more strength and coordination for that because the hair on Hope’s back isn’t as long. And eventually Saambili will start to crawl and move around on her own independently.

When do we think she might start walking?
Right now, she can definitely stand up on her own if she’s holding on to something, so she has the strength in her arms and legs. She wants to crawl, we can tell. But mom is being very cautious and protective. At this point, it’s kind of up to Hope.

What kind of interaction has she had with the other members of her family troop at this point?
When she was first born, Subira (her dad) immediately came over and inspected her. He put his lips on her very gently, and touched her gently. Periodically, he will come over and look at her. As she gets older and becomes more mobile, that’s when she’ll really start interacting with some of the other members. They may “babysit” or play with her. She may jump around on them, essentially using them as a playground. We’re obviously not to that point yet because she’s still so young.

Megan gently inspects baby Saambili.

But the other two females has shown a lot of interest in her. Megan has shown the most interest – she’s the youngest in the group, and she’s grown up in family troops her whole life. For the first few weeks of Saambili’s life, Megan was constantly following Hope around because she wanted to look at the baby. And she would hold Saambili’s hand – she’s been very gentle.

Hope doesn’t mind this?
No, Hope deals with Megan really well. If Megan gets too rough or if the baby needs to sleep, Hope will just move Megan’s hand away or turn her body so Megan can’t see Saambili. Megan is very persistent, so Hope spends a lot of time dealing with that. Luckily, Hope is a very socially-savvy female, so she knows how to handle all of this. Sometimes you’ll see Hope holding Megan’s hand. That’s not necessarily because they’re friends, she’s just saying “stop touching the baby.” What we’re seeing from Megan is a very normal level of interest from a young female, though.

And Shanta is very interested in the baby, too – she’s even cleaned her a few times. With Shanta being the lower-ranking animal in the troop, she isn’t able to spend as much time with the baby – although we think she would like to.

With Subira, it’s really up to him on what role he’ll play. Silverbacks are the protectors of the family, but every silverback is different. A lot times they’re just sort of a jungle-gym. So if they’re napping, the baby might jump onto them from things, hit them, run around, or pull their hair. We suspect Subira will be really tolerant of all those things, which will be oh-so-cute to watch.

What is the biggest threat that Saambili’s wild counterparts face?
Habitat loss and being hunted for bushmeat. Mining and other agricultural and farming activities are taking away food sources and habitat for gorillas in the wild. And then there’s poaching, where snares are often used. Even if they don’t get caught in a snare, gorillas can lose an arm or die from infected wounds. There are actually some troops in the wild that have learned to recognize snares and undo them, which is great.

Baby Saambili is very curious and ready to explore!

How can the general public help protect gorillas?
Be conscious when you’re buying wood or paper products. Make sure you’re buying rain forest-friendly and sustainable products that are made from recycled materials so you’re not contributing to deforestation.

You can also bring your old cell phones, tablets, MP3 players, etc. to the Dallas Zoo, and we’ll recycle them responsibly!

These electronics require the mineral coltan, which is mined in Africa – the natural habitat of critically endangered gorillas and other species. Deforestation and mining associated with coltan production have impacted and displaced gorillas, forcing them dangerously close to extinction. Recycling these devices and extending the life of electronic devices (do you really need a new mobile phone as soon as your contract is up?) reduces the demand for coltan mining.

Celebrating International Vulture Awareness Day at the Dallas Zoo

Help us #SaveOurScavengers

 

Known as “nature’s clean-up crew,” vultures have a pretty dirty job. But they play such a vital role in their ecosystems, and they help out humans too! Unlike other birds of prey vultures are scavengers, which means they eat carrion (aka, dead animals). This helps prevent the spread of diseases such as rabies, anthrax, cholera, botulism, and tuberculosis, which can often be found in those animal carcasses.

What a thankless job. Luckily, vultures are equipped with adaptations that help them thrive in this role.

  • Vultures’ highly acidic stomach acid and super strong immune system allow them to eat decaying and potentially infectious meat that would make most other animals sick.
  • Some vulture species rely on keen eyesight to locate their food; others rely on their keen sense of smell to search out hidden carcasses by detecting gasses that are released during decomposition.
  • Vultures will vomit up semi-digested food to ward off predators, or to help lighten their weight if they need to escape from a predator quickly.
  • Many species of vultures have bald heads – there is speculation that this helps them stay clean, but this may also help them with temperature regulation.

Unfortunately, these amazing birds are under siege when it comes to survival.

  • 16 of the 23 vulture species in the world are considered threatened, endangered, or critically endangered.
  • Vultures have been disappearing from Africa at an alarming pace over the last 30 years, having declined between 62-95% across the continent.
  • Globally, vultures are the most endangered group of birds.

Vultures are being poisoned by the thousands, especially in Africa and Asia; sometimes indirectly by farmers who poison large carnivores that threaten their livestock. The vultures consume the poisoned carcasses, and die as a result. More alarming is that poachers have begun intentionally poisoning the carcasses of poached animals to kill off vultures who may give away their location to authorities.

Which is why the first Saturday of September is now known as International Vulture Awareness Day, to help raise awareness about vultures and the conservation issues they face around the world.

Vultures at the Dallas Zoo

We love our vultures here at the Dallas Zoo! We care for eight different species, and we take pride in educating our community about the importance of saving these amazing birds.

You may have seen our black vulture, Baldwin, strut his stuff on the Wild Encounters Stage. Baldwin has been making our guests fall in love with vultures since 2016, when he came to us from a local rehabilitation facility. Fittingly enough, his third birthday falls on International Vulture Awareness Day this year.

“We love introducing Baldwin to our guests!” says Robin Ryan, Supervisor of Animal Encounters. “He has such charisma and personality, which I think can inspire people to see vultures in a more positive way.”

We’re also celebrating International Vulture Awareness Day throughout the weekend, during our special Member Mornings events this Saturday and Sunday. Members can join us for a private Vulture Keeper Chat both days at 8:30 a.m. in front of the vulture habitat, and we’ll have special vulture-themed arts & crafts projects.

We hope you’ll join us in wishing Baldwin the happiest of birthdays. And use International Vulture Awareness Day as your incentive to help us change this species’ reputation – toss out some of the fun facts above and tell others about these crazy-cool birds.

Texans come together to save our state reptile

Although Texas horned lizard populations are increasing thanks to community efforts, there is still work to be done.

Head west on I-20, and in no time, you’ll notice large, red formations of sedimentary rock standing like mountains amid the mostly flat, arid earth and rolling plains. This is Rotan, Texas  – far from the impressive view of Downtown Dallas’ protruding skyscrapers. Here you’ll find many creatures that dominated these parts in the days of the Wild West still making their homes. However, the thousands of snakes, lizards and insects that are all well adapted to survive these harsh conditions, are no longer thriving as in those days not long ago.

Recently, a group of Dallas Zoo staff members, interns and volunteers took the drive to the Rolling Plains Quail Research Ranch to study one reptile who has made the ranch its home – the native and beloved Texas horned lizard. The facility was established in 2007 for the purpose of enhancing the abundance of the northern bobwhite, a ground-dwelling quail native to the United States, Mexico and the Caribbean. Rolling Plains Quail Research Ranch preserves 4,720 acres of land to maintain the natural brush cover necessary for quail conservation efforts. This undeveloped land is the ideal setting for the scaly Texas horned lizard. The brush cover provides shelter from predators, which is essential, as their toad-like bodies tend to slow them down.

Rolling Plains Quail Research Ranch in Rotan, Texas

“The area is managed for quail, with shortgrass and tallgrass prairie land, which is also vital to horned lizards and their prey, harvester ants. Horned lizards live in a similar niche as quail and benefit from the preservation of this land, as do many other animals,” Dallas Zoo reptile keeper, Shana Fredlake observes. “This is native habitat for these animals, so keeping it pristine helps this population stay stable and helps us observe their natural behaviors and monitor growth rates.”

Although the horned lizard was their primary focus, the group was also delighted by the company of a few tarantulas and snakes, even stumbling across a rattlesnake; a real treat for Dallas Zoo reptile supervisor, Bradley Lawrence who has a special fondness for the noisy, venomous reptile. Lawrence believes the conservation work being done today has also benefitted other reptile species native to Texas.

“Most folks in Texas will do anything they can to protect, donate and manage land for horned lizards. They don’t know it, but this helps conserve other species that are not looked on as favorably,” Lawrence shares.

Our research team studied Texas horned lizards in hopes of restoring their population.

The community’s willingness to pitch in and help the conservation of the Texas horned lizard is promising, but much work still needs to be done. Despite conservation efforts to reverse the decline of the species, the horned lizard remains state-threatened.

“The Texas horned lizard has disappeared from about 60% of its former range here in Texas due to invasive fire ants, over-collection, and habitat destruction,” Lawrence adds. Despite the numbers, he remains hopeful for the species: “They are charismatic, gentle reptiles, and everyone that sees them falls in love.”

“It makes me happy to see Texas have a state reptile and that people love this reptile,” Fredlake says. “If we can coexist without destroying every part of their habitat, there is a chance to bring them back to all parts of their former range.”

By studying population density, habitat preference, diet, sex ratios, and activity patterns, we’ve developed a greater scientific understanding of our state reptile and how to best contribute to its conservation. For more information about our Texas horned lizard conservation efforts, click here.
