An inside look into hatching Caribbean flamingo chicks

Hatched just before Dollar Day in 2011, chick Buster was our first Caribbean flamingo baby in more than two years.

Bird keeper Marnie Bacon guest-blogs on Zoohoo! 

Dallas Zoo’s summer Dollar Day in 2011 was a hot and crowded one — and one our bird department will never forget. Spotted in the ZooNorth flamingo pond was a hours-old Caribbean flamingo chick. The little one hatched that day, making it the second Caribbean flamingo chick to hatch at the Dallas Zoo in more than 20 years. We named the first chick Buster, and our Dollar Day girl Georgia (after George Washington on the dollar bill, of course). We were so proud to have hatched these chicks, and today, they’ve come a long way.

Today, Buster is fostering his own chick.

This year’s Caribbean flamingo breeding season started the same as previous years — with a lot of hard work by the keepers to get the birds’ nesting area ready. Our close observations of the flamingo flock’s behavior year after year resulted in the knowledge of the ideal conditions needed for a successful season: building a moat, tilling the soil, and keeping the area desirable for flamingos to nest build.

This year, the birds built 30 nests and laid more than 20 eggs. To safeguard the eggs, we carefully collected all of them to be artificially incubated and provided the adults “dummy” or artificial eggs to incubate.

With colonial nesters, like flamingos, we have the opportunity to allow pairs that may otherwise lay infertile eggs, the chance to foster rear chicks. This year with our flamingo flock, there were four fertile eggs produced, two of which came from the same biological pair. Flamingos will only rear one chick at a time, so one pair that laid infertile

eggs was selected and provided the opportunity to raise a chick. But there are more than 60 flamingos in our habitat — so how do we choose?

Dallas Zoo’s successful breeding season has brought four new chicks to the Caribbean flamingo pond!

There are various factors that go into the decision process. Whether or not the pair is incubating a dummy egg, the timeframe in which the egg is hatching, and the behavior of the adults are all the main factors. It always makes us a bit nervous providing the opportunity to new parents, as we don’t know how they will do — but careful monitoring and proper surveillance by keepers ensures that the process goes smoothly!

This year, after weeks of relentlessly defending their nest mound, Georgia and her mate welcomed a very special chick who, coincidentally, hatched on Dollar Day. Buster and his mate were also carefully selected as a foster pair and are also now the proud foster parents to a chick that hatched on July 6.

Six years after that fateful Dollar Day, things have come full circle and these two birds now have chicks of their own! Come out to the Dallas Zoo and see these babies, and our two other chicks, grow up in the Zoo North flamingo pond.

Bird fostering: How zoos pull out all the stops to save animals from extinction

Dallas Zoo Assistant Supervisor Marcie Herry gives San Antonio Zoo Senior Keeper Serenity Hyland one of two kori bustard eggs to be raised by the San Antonio Zoo.

What does it take to ensure the survival of a genetically valuable bird? Sometimes it means flying halfway across the country to pick up an egg and bring it back to Dallas to be fostered by a different set of parents.

This temperature controlled container was used to safely transfer the egg to the San Antonio Zoo

That was the case this spring bird season when a lappet-faced vulture egg was laid by a mom at Disney’s Animal Kingdom in Florida. The mom, unfortunately, didn’t have the best track record caring for her young. Luckily, the Dallas Zoo has a great set of lappet-faced vulture parents that could act as foster parents—yes, there are foster parents even in the animal kingdom!

Fostering like this and even hand-rearing are options that Association of Zoos & Aquariums institutions have to consider for new births or hatchings to conserve and save wildlife.

The lappet-faced vulture hatching is just one example of the decisions the Dallas Zoo deals with every spring with 700-plus birds on grounds, spanning more than 100 different species—many of which are endangered, declining, or near threatened.

When the parents aren’t available, sometimes zookeepers step in as the foster parents, like with a new kori bustard hatchling this spring. We’re hand-rearing one of these, and another two kori bustard eggs were picked up by the San Antonio Zoo, where they have the space and manpower to raise these chicks.

Eggs sit in an incubator at the Dallas Zoo

In other instances, zoos even cross-foster between similar species if the same species is not an option. For example, a lappet-faced vulture chick may be reared by a white-backed vulture and vice versa. This is done very carefully, and only in the right circumstances.

Regardless of what it takes to ensure a chick’s survival, the Dallas Zoo and other AZA-accredited zoos are doing everything it takes—from hand-rearing to fostering internally or even delivering eggs and chicks to zoos hundreds of miles away—to save animals from extinction.

The next time you peer out into the flamingo pond and see a unique species of bird, remember—it might have been raised by mom and dad, or it may have taken a different path, like being raised by humans, foster parents, or even a different species altogether.

Happy first birthday, Ajabu: Looking back on a year of milestones for our baby elephant

2017_Mar_18_DallasZoo_0722_Ajabu_mud_better

It was 7 a.m. on Saturday, May 15, 2016 – the Zoo was just waking up and keepers were filing in, when two elephant keepers shook the barn with squeals of joy as they discovered a little grey bouncing baby boy. Just hours before, elephant Mlilo had delivered a 175-pound, 3-foot-tall calf to our somewhat surprise.

The baby, already standing, nursing and totally unfazed, would be the first African elephant calf born in a U.S. AZA-accredited Zoo in more than two years.

The keepers quickly executed their, “Surprise! A baby’s been born!” procedures to ensure the vet and animal care teams were immediately aware of the newborn.

Baby Ajabu at just three days old.

Baby Ajabu at just three days old.

But, the one who knew exactly what she was doing, Mlilo, took it all in stride. She’d been growing this baby for nearly two years, and her maternal instincts were alive and kicked in right on cue. She was born for this.

Two months prior, Mlilo arrived aboard a chartered 747 jet from drought-stricken Swaziland, Africa, as part of an intricate airlift to save her and 16 other elephants from being culled. This, in turn, saved her AND her beautiful baby boy.

Our animal experts suspected Mlilo was pregnant, but all hormone testing came back inconclusive. Regardless, we were very careful with Mlilo’s day-to-day care, and were able to create the positive conditions surrounding Ajabu’s successful birth.

Estimated to be 15 years old, Mlilo arrived here thin and underweight, but better nutrition in just the few weeks leading up to her delivery helped her gain 300 crucial pounds. And over the course of the next five months, we allowed mom and baby much time to bond privately, and grow together, while we worked to “baby-proof” the Giants of the Savanna habitat.

As we celebrate this precious baby’s first birthday, we look back on the moments that truly take our breath away. And if you weren’t a fan already, we’re certain that over the past year, this rambunctious boy has made you fall in love with his vulnerable species.

We insist you binge watch:

  1. Captured on the barn cameras, Ajabu’s birth; mom’s gentle nudge encouraging baby to stand; his first steps; his first time nursing, will forever remain one of those “pinch us, we’re dreaming” moments. (And yes, utter disbelief caused much pinching.)
  2. That time newborn Ajabu wouldn’t let mom sleep, and Mlilo obliged with his antics Every. Single. Time. #MomGoals
  3. When baby Ajabu took his first dip in a kiddie pool and we thought there was nothing cuter. (We were quickly proven wrong. See No. 4.)
  4. Baby boy received his first ball and played so hard that food and water were the only things that could tear him away. Priorities.
  5. Another major first, the day Mlilo and Ajabu explored their “baby-proofed” habitat This was an unforgettable moment.
  6. Then seeing it all come full circle as baby Ajabu and Mlilo ventured into our largest habitat with other herd members.

Hmm, can you still call a 4-foot-tall, 800-pound, one-year-old elephant a “baby”? Actually, don’t answer. He’s our baby and always will be.

Ajabu, whose African name means “wonder,” “amazing” and “extraordinary” is a remarkable ambassador for his troubled species, inspiring guests daily to help find answers to the grave crisis elephants face in Africa. He represents so much.

He’s here because we took a chance, a major one. And the way children light up when they see his tiny trunk, his perfect ears, and hear his little trumpets – it’s unexplainable. Ajabu plays such a key role in inspiring our next generation of wildlife warriors to save species from extinction and ensure we never know a world without the majestic, powerful African elephant.

Happy first birthday to our baby boy Ajabu. You mean more to us than you will ever know.

And a thank you to Mlilo. You’re the kind of protective, playful, and present mother all moms wish they could be. Here’s to a very Happy Mother’s Day, mama Mlilo.

Nests 101: Building a home out of ANYTHING

IMG_2819 Wattled Crane on nest CS

Bird keeper Eric Lutomski guest blogs on ZooHoo!

IMG_8272-GoldenTaveta Weaver-CBEveryone knows birds build nests, but not everyone realizes just how many different kinds of nests there are! Nests can be as small as a teacup or as large as a dinner table and can be plainly out in the open or carefully hidden away.

Nests are constructed from all sorts of materials like carefully woven fibers or large tree limbs. Sometimes birds use even unusual materials, like saliva for glue or spider webs for camouflage. Many birds don’t make nests out of anything at all—their eggs are instead laid in burrows underground, inside a hollow tree or log, or even on a well-shaped ledge of rock.

Here at the Dallas Zoo, letting birds build their nests is a very enriching and stimulating experience. It lets the birds perform their natural behaviors like location selection, material gathering, and nest construction.

_MG_1200-Spoonbill chick and mom-CBIn many species, building the nest is part of courtship between males and females and is important for breeding success. Ideally, all birds at the Zoo would be able to build their own nest, but sometimes they get a bit of help from the zookeepers.  It can be anything from extra grass or sticks to mesh platforms for support structures.  We want to ensure that eggs or chicks don’t fall out of the nests.

Large birds like vultures, eagles and storks don’t like to nest on the ground, so keepers provide them with elevated platforms and lots of sticks of many shapes and sizes that the birds can weave together to form their nests.

Songbirds and other small birds, like jays and pigeons, prefer their nests to be bowl shaped.

Many birds like hornbills, lorikeets and cranes nest in tree cavities or other secluded locations like burrows or tall grasses, so keepers provide boxes for them so they can nest in privacy.

So next time you visit the Zoo, take a careful look! Is there a nest hiding in any of the exhibits? Where are they? What birds might be using them? Remember that you can take this knowledge home with you and build your own nest box for the birds in your neighborhood. (Bird Houses are nest boxes, too!)

A hugely successful year with AAZK

Russell Pharr, elephant keeper and president of the American Association of Zookeepers Dallas chapter, guest blogs on ZooHoo!

IMG_6203 SFRTwenty-sixteen was a very successful year for the Dallas American Association of Zookeepers Chapter!  We hosted a huge range of great events and, while having an amazing time, helped make the world a better place for animals.

Join us as we take a look back at 2016:

Bowling and Sailing for Rhinos

IMG_6113 SFRThis was our 25th year participating in the 26-year-old Bowling for Rhinos program, and our fifth year partnering with Alley Cats in Arlington.  In addition to bowling, arcade games, miniature golf, and laser tag, we debuted a BFR photo booth, had a bowling pin decorating contest for the second consecutive year, and hosted our first-ever takeover on Dallas Zoo’s Facebook to help promote the event!

Most importantly, Bowling for Rhinos in Dallas raised $18,000 – 100% of which goes directly to save rhinos, cheetahs, and other animals in Kenya and Indonesia. Nationally, AAZK chapters in the U.S. and Canada raised over $600,000 – an all-time record!

Our one-of-a-kind Sailing for Rhinos event raised $6,000 to help AAZK causes. We continued our partnership with Corinthian Sailing Club and had great weather once again for one of our favorite events.

Labor Day Book Sale

Our annual book sale broke records this year, raising more than $2,000 over three days of selling used books, DVDs, and other items donated by the Dallas Zoo community. Profits were split between the Okapi Conservation Project (the okapi was our 2016 “featured animal,” decided by a staff vote in our second annual AAZK March Madness contest) and the Bat World Sanctuary in Weatherford, Texas. Our book sale continued a partnership between Dallas AAZK and the Zoo’s Enrichment Committee as we sold animal-painted magnets and bookmarks, and allowed us the perfect platform to introduce tote bags with our chapter logo printed on them!

Painting with a TwistOther Conservation Events

Our first-ever painting event, the Painting With a Twist for World Giraffe Day in June, not only raised $1,300 for the Giraffe Conservation Foundation, but also provided a fun way to honor the memory of Dallas Zoo’s own, late Kipenzi.

Our first-ever Salamander Saturday event in May helped raise funds and awareness for some of nature’s less-appreciated creatures. Our contributed funds also helped the Foundation for Conservation of Salamanders to offer a Texas-specific grant for researchers working on salamanders (and we have some amazing endemic species here)!
