Senior Zoologist Dana I. and Assistant Bird Supervisor Nathan C. guest blog on ZooHoo!
We arrived in Kimberley, South Africa on Tuesday, March 12, after a long journey from Dallas. We were greeted by our fellow AZA colleague, who’s been taking care of the flamingo chicks for the last few weeks. We were immediately taken to the Kimberley SPCA, where the chicks are being cared for, to jump in and quickly learn the ropes. The SPCA has the youngest of the 1,800 chicks rescued from the Kamfers Dam. All of the chicks are doing well!
first group of older chicks were brought in from the initial rescue. This group
is already feeding themselves and, because of the specially formulated food
they’ve been eating, they are starting to turn a bright pink/red a little bit
earlier than normal. We are continuing to weigh these chicks every few days to
make sure that they are continuing to gain weight and are staying healthy.
second set of chicks came from a later trip to the Kamfers Dam. After the
initial rescue, dogs disturbed the flamingo colony remaining at the dam and
caused more flamingos to abandon their nests. Volunteers went in and collected
the abandoned eggs, and now there is a group of 18 chicks. These chicks are
still being hand-fed three times a day at 8 a.m., 4 p.m. and 10 p.m. Every
morning the chicks are weighed so we can determine how much food to feed them
for the day. We also make sure the little chicks get plenty of time outside for
some all-important sunshine and exercise.
On Thursday we got a chance to go out to Kamfers Dam and see the flamingos that are still there. There is still a large colony of adults raising an estimated 5,000 chicks. They are being monitored but continue to do well.
Baby gorilla playdates will be endless this year at the Dallas Zoo! We are welcoming our second baby gorilla born in 21 years – and the second born in just the last year.
Our 13-year-old critically endangered western lowland gorilla Megan quietly delivered the infant in the early morning on Thursday, March 7. This is Megan’s first time raising a baby and both are doing well; Megan has been very attentive, and the baby is nursing often and is keeping a strong grip on mom.
This birth brings another new wave of excitement for the Dallas Zoo – this is the first time we’ve cared for two baby gorillas at the same time in almost 50 years. Nearly nine-month-old gorilla Saambili (born June 25, 2018 to mom Hope) now has a half-sibling playmate, and she’s already shown much interest in the newest addition.
“Gorilla conservation is a
huge part of Dallas Zoo’s mission – we’ve been unwavering in our commitment to
save them in the wild, and now we’re contributing more than ever to their
protection in human care,” said Gregg Husdon, Dallas Zoo’s President and
CEO. “We’ve gone from not having an infant
gorilla for two decades, to now having two babies back-to-back, and it truly
shows the dedication and perseverance of our world-class animal experts.”
Mom Megan was paired with silverback Subira (also the father to Saambili) on an Association of Zoos and Aquariums’ (AZA) Species Survival Plan breeding recommendation in hopes of increasing the western lowland gorilla population in North America. Subira has proven to be an excellent father to Saambili, and he’s recently been observed giving her special attention and playtime during this quiet period for the troop.
the most ideal social situation for our troop – both of our babies will be able
to learn, grow, and play together,” said Linda King, Dallas Zoo’s Primate Supervisor.
“This is also a big moment for mom Megan who has been extremely interested in
Saambili since day one. She now has the wonderful opportunity to raise a baby
of her own.”
The Dallas Zoo cares for ten gorillas, including the bachelor troop who live on the south side of the Gorilla Trail, and the family troop who live on the north side. All six family troop members have remained behind the scenes so Megan and her baby can bond privately. Zoologists will take their cues from Megan on her comfort level and readiness to explore the habitat. A moniker and the baby’s gender reveal will come within the coming weeks.
to the Dian Fossey Gorilla Fund International, there are approximately 350,000
western lowland gorillas left in Africa. The population decline is contributed
to habitat destruction, poaching for bush meat, animal trafficking, and disease.
to the Congo Basin, western lowland gorillas are the smallest of the subspecies
and the least critically endangered. There are roughly 3,800 Grauer’s gorillas,
880 mountain gorillas, and 300 Cross River gorillas remaining in the wild.

“They say an elephant never forgets. What they don’t tell you is, you never forget an elephant.“
In the early 1900s, an estimated 3-5 million elephants
thrived across a vast range in Africa. Today, there are only about 415,000
African elephants remaining in the wild, and their range has been reduced by
nearly half. They have suffered from massive amounts of poaching for their highly
prized ivory tusks. The demand for ivory was so steep that in 1989, an
international trading ban was put into place. However, illegal poaching
persists and results in the deaths of approximately 96 elephants every single
If current trends continue, it is entirely possible that they will be extinct in our lifetime, which is why we are on a mission to support elephants in the wild. This week, the Dallas Zoo has set a goal to raise $10,000 through grassroots fundraising to support conservation efforts in the wild. Read on to learn more about these amazing animals and what you can do at the Dallas Zoo to help!
Dallas Zoo’s herd
The Dallas Zoo’s award-winning Giants of the Savanna habitat is home to 8 magnificent African elephants. The “Golden Girls:” Jenny (42), Gypsy (37), Congo (41), Kamba (39) and the Swazis: Tendaji (approx. 15), Mlilo (approx. 15), Zola (approx. 15) and baby Ajabu (2).
The design of the Giants of the Savanna habitat was based
on field research and allows our elephants to be more active as they look for
food, water, and companionship, just as they would in the wild. Treats are
occasionally hidden in trees or in niches around the habitat, and elephants
exercise their trunk muscles to find those treats or to reach high-hanging hay
nets. They travel over small hills, into waterholes, and along an off-exhibit
pathway for additional workouts.
The Dallas Zoo elephants also have the luxury of their behind-the-scenes barn. The innovative barn is optimized for climate control – with radiant floor heating and padding in the winter months and movable walls that provide cross-ventilation in the summer heat. This barn also has a community room with 7-foot-deep sand floors used to bury food and toys, since the elephants are accomplished diggers.
An elephant’s life
are well-known for their intelligence, close family ties and social complexity,
and their capacity to remember other individuals and places for years. Elephants
have strong, individual personalities that affect how they interact with other
elephants and how others perceive them.
example of this at the Dallas Zoo can be seen among the Golden Girls. Jenny,
our oldest resident, is vocal and playful. Gypsy is mischievous, eager, and
loves attention. Congo is inquisitive and enjoys exploring. Lastly, Kamba is
friendly and cautious and enjoys being around the other elephants.
The position of head
of the family is held by a female known as the “matriarch.” Matriarchs express
their dominance in both competitive and cooperative situations. The most
successful leaders seem to be confident individuals who are able to command the
respect of others through both their wisdom and their charisma.
An elephant herd
consists of one or more (usually related) adult females and their immature
offspring who feed, rest, move, and interact in a coordinated manner and are

Since January 2019, a group of dedicated conservation
interns has been learning all about African elephants – through interviews with
keepers, behind-the-scenes tours, and tons of research. It all culminates in
this special Conservation Week (March 9-16), when we will be engaging Dallas
Zoo guests to promote awareness about elephants and inspire conservation
This is an exciting time for us, as we get to show our months of hard work and dedication to the conservation of elephants. We have also worked countless hours ensuring that we are getting different departments of the zoo engaged and excited for the upcoming week of fun, information, and memorable experiences.
How YOU can help
way you can help elephants is to NEVER
purchase ivory or anything made from parts of elephants. Also share this
information with others around you so that you can help spread awareness and
begin the cycle of change.
A group of Dallas Zoo interns, including myself, have
organized a jammed-packed week full of fun events and conservation engagement.
We hope you join us at the Dallas Zoo during Swing Break through
March 17 to help us create a better world for animals.
We’ve set ambitious goals for Elephant
conservation, and we need your help to reach them:
$10,000 for elephant conservation – Help
us reach this goal by purchasing elephant swag from us at our Campaign Station
in the Zoo, or by attending any of the events during Swing Break.
2,500 personal pledges – Stop by
our Saving Elephants Campaign Station to take a pledge for pro-wildlife
behaviors that benefit elephants.
Please support our efforts of raising funds for elephants
so we can continue making a positive impact for the lives of the most majestic
Animal Care Supervisor of Birds and the Artificial Nest Development Project Coordinator for the Association of Zoos and Aquariums (AZA), Kevin Graham, guest blogs on ZooHoo!
After spending a day at the African penguin artificial nest manufacturing facility, it was time to head to Addo South African National Parks (SANParks) to meet the Marine Ranger team. This entailed an arduous drive along a pitted dirt road to the departure point for the helicopter that would ferry all of us across the ocean to our first penguin colony, Bird Island.
The artificial nests destined for this round of installation on Bird Island had arrived the day before, or at least most of them had. As is often the case, the reality of a situation doesn’t always match up with the plan that was put into place.
The group arrived at the “helipad,” a flat clearing in the middle of the massive sand dunes that’s used to land the helicopter and sling equipment over to the island. The artificial nest team members met the Addo SANParks Section Ranger, the island Colony Manager and a team of marine rangers and other local staff for a rules briefing. Bird Island is a destination that very few people have the opportunity to visit – it’s not accessible to the public at any time, and in normal circumstances the only people lucky enough to spend time on it are either rangers or field researchers that have received authorization. Our strong working relationship with Addo SANParks over the years allowed the nest project to do something that is extremely rare – bring a large team of non-locals to the island to work.
The team boards a helicopter to travel to the remote Bird Island.
With all of the gear, supplies and equipment ready, we had nothing left to do but eagerly await the arrival of the helicopter. The pilot has worked closely with Addo SANParks for quite a long time and is extremely helpful with access to the island. The only ways to get to Bird Island are via helicopter or by a boat trip that can range from two to five hours each way, depending on water conditions.
Several flights would be needed to transport the nests and the remaining supplies to the island, with the weight slung in a cargo net beneath the helicopter. The maximum weight capacity for the airlift on a calm day is only about 550 kilograms, the equivalent of 37 completed nests. We had 300 nests ready to be transported, in addition to the necessary supplies to survive four days on an island with little in the way of amenities. We estimated that we’d need approximately 10 trips across to carry all of the people, supplies, nests, and equipment.
The forecasted calm weather gradually turned into high winds after a couple trips across the ocean, which caused excessive air turbulence. This meant that fewer nests moved per airlift. The wind also didn’t cooperate on the next couple of days, so the remaining nests weren’t able to be transported until Friday, Feb. 22. Unfortunately, this was the last day the artificial nest group was slated to be on the island. On the plus side, the Marine Ranger team from Addo SANParks was trained in the assembly method for the nests and are familiar with the process of placing the nests correctly.
Members of the artificial nest team worked from early morning to the end of the day on any and every task that needed to be accomplished during our four-day stay on Bird Island. This included assembling the 35-pound artificial nests, carrying them into the colony from the boat house on the far end of the island, updating and maintaining the precision electronics used to monitor the nests, cleaning up marine debris, surveying for sick and/or injured birds, removing the older, ineffective nests from many years ago, GPS tagging of the new nests, and documenting the work. With the help of the dedicated Marine Ranger team from Addo SANParks, the nests were assembled and moved into place for the penguins to begin using. Since we had the equipment and knowledge, the nest team members also were able to work on the desalination plant for the island, which had been broken and unusable recently.
A penguin quickly makes use of one of our artificial nests.
In the long run, the four days of work went off mostly without a hitch, and everything that was intended to be finished was accomplished.
And, if you’re wondering if all of this is worthwhile… within 24 hours of the new nests being put into place, the occupancy rate was already 57%. In a massive surprise to all of us, one overly ambitious hen even laid an egg in a new nest less than half a day after it was placed. The feeling of awe is overwhelming, watching her look for somewhere she could safely incubate her egg and potentially raise a chick. It’s even more so when we realize we’ll provide thousands of birds this same opportunity of safely raising their offspring during the course of the project.
And on that note, we’ll be leaving Port Elizabeth to head to the Western Cape, where we’ll work in several more colonies. But first: a very long, very hot shower for us to wash about three inches of dirt away.
But first, we worked on an incredible side project today at the penguin nest manufacturing facility in Cape Saint Francis, South Africa. I was able to inspect the work being done, and talk with the folks who have been building the nests, since the manufacturing site opened up a little over a month ago. This site is being coordinated under the watchful eye of Trudi Malan of Dyer Island Conservation Trust. This location is currently home to many tons of raw materials that are being converted into penguin nests at a rate of about 20 nests per day. While this doesn’t sound like a lot, these nests are 100% made by hand and have a very specific formulation of products that has to be prepared and a significant amount of materials that have to be worked in the exact order in order to properly build the nests.
The construction team builds the nests, which involves a very detailed process.
The team members that are building the nests have not only become very efficient and skilled at the process, they’ve also begun to understand that the project they are assisting with is destined to make an improvement in the lives of an endangered species. These team members have a strong and growing pride in the work that they are doing and it shows. For many of them, this job is helping them learn new skills and offers them financial assistance. But more than that, they see their role of building the nests as a part of a bigger picture that can potentially save the lives of birds that desperately need help.
To construct the nests, they begin with preparing the Sealmac geotextile fabric cutouts, which will be used as the skeleton of the nest construction process. These individual pieces of geotextile fabric are then thoroughly impregnated in a ceramic slurry composed of a very specific ratio of several compounds. If the ratio of compounds is out of balance by even a small amount, the overall strength and integrity of the end product can be compromised. Each piece of the geotextile fabric is layered onto the mold in a very specific sequence, which builds up the integrity of the structure. Once the numerous pieces of slurry-filled fabric are all securely in place on the mold, they cure for at least 24 hours until any further work can be done.
Dallas Zoo’s Senior Zoologist Julie Farrington also inspects the nests.
The next day the finished nests are removed from the molds and moved into the drying area to allow these completed pieces to continue curing for at least another 48 hours. Any work that is attempted during this curing time would have a strong likelihood of causing damage to the nest structure that would be very difficult to repair. Once a period of 72 hours minimum has passed, the pattern for the ventilation holes in the nest is traced onto the nest structure, and the ventilation holes are drilled. This pattern has been designed to increase the thermal venting of the nest structure on hot days and is a critical component in the thermoregulation inside the nest.
When looking at the end product of the nest, it doesn’t look like something that would be all that complicated, however there is a tremendous amount of science and research that went into the development of these penguin nests. Between the materials research; the design research; the multiple extensive rounds of testing; and finally the ongoing construction of the finished product that is beginning to be installed in colonies, this has been a very unique challenge. Recreating the perfection of Mother Nature is not an easy task, but thanks to the dedication of the nest project team consisting of members from Dyer Island Conservation Trust, Pan-African Association of Zoos and Aquaria, the Dallas Zoo/AZA SAFE, and especially those people and organizations that have believed enough in the potential of providing homes for endangered penguins, we are confident that we’ve come as close as possible.
Really early tomorrow morning (which will be really late at night for you guys in the U.S.), we’ll be departing for Bird Island to begin installing the first of the finalized nests in the colony there. Thanks to the ongoing support and assistance of ADDO SANParks, we will be transporting the nests and supplies over to Bird Island by helicopter. This saves a huge amount of uncertainty in access to the island since it’s a two hour boat trip each way in calm waters or up to a five hour boat trip each way in rough waters, which usually ends up with a large number of the team members leaning over the edge and relieving themselves of their breakfast. More to come later, assuming we survive.
There’s a whole lot more in the way of photos and videos to come, so stay tuned as I continue to update you with field notes on this unprecedented project to save endangered African penguins.
There’s so much going on at the Dallas Zoo, we had to start a blog to tell you about it all. Have an idea for a story or a question for us? Email Info@DallasZoo.com and put “ZooHoo!” in the subject line.
