nce in a lifetime, you meet a remarkable person—one who impacts your life or your organization and leaves an indelible mark on the world around him. Conrad Prebys was that person for San Diego Zoo Global (SDZG). It is the generosity of philanthropists that allows organizations like ours to grow. Not only did Conrad’s generosity help us grow and thrive, it ushered in a new era of philanthropy at SDZG. Conrad was a humble man with a deep, heartfelt laugh that was contagious. One of his most endearing qualities was his ability to captivate people with his stories. During a breakfast meeting, he regaled me with memories of the joy he found in the animals at the Zoo during his early years in San Diego, before he’d hit his stride. He said this with such exuberance and sincerity that I knew we shared a common passion. So, it wasn’t too long before we invited Conrad to be a donor. His first question was, “what is the largest gift the Zoo has received to date?” Once we told him, he responded that his goal was to give the largest gift ever received. He did. And he kept on giving, along with his partner, Debbie Turner. As a self-made man from modest beginnings, it delighted Conrad to have the opportunity and the wherewithal to give to something that meant so much to him. This spirit of philanthropy—giving from the heart—has benefited tens of millions of visitors to SDZG, as well as the animals that gave Conrad so much enjoyment. It also inspired others to give. Conrad taught us that it doesn’t matter how large or small a gift is—it is the spirit with which it is given that matters. We feel a great loss at Conrad’s passing on July 24, 2016. When you visit Polar Bear Plunge, Elephant Odyssey, or Australian Outback, take a moment to remember Conrad and the incredible legacy he has left for our children, our children’s children, and the animals he adored.

The Best Nest Whereâ&#x20AC;&#x2122;s the best place for an egg to hatch? That depends on the bird. ILLUSTRATIONS BY AMY BLANDFORD SDZG ILLUSTRATOR

TEXT BY DONNA PARHAM STAFF WRITER

BOBBING ALONG A floating mass of aquatic plants provides the perfect platform for a pair of red-necked grebes. Anchored to nearby vegetation, the nest is situated to protect eggs and chicks from mammalian predators.

GROUNDED For the semipalmated plover, the best nest is little more than a shallow depression in sand, among rocks, or in sparse vegetation. A female lays three or four mottled eggs that are pointed at one end. This pyriform shape keeps the eggs from rolling away.

HIGH AND DRY A flamingoâ&#x20AC;&#x2122;s single, chalky white egg hatches atop a pile of mud. Both male and female construct the tall nest, heaping and packing soft mud into a volcano-shaped mound. The high nest protects the precious egg from changes in water level. 8 / ZOONOOZ / SEPTEMBER 2016

HANDYMAN Using strips of palm, rice plants, or grass, a male baya weaver knits together a hanging nest with an entrance tunnel. SOFT AND STRETCHY With spider webs, a female hummingbird binds together twigs, moss, soft plant fibers, and bits of leaves and lichens. The tiny, cup-shaped nest is soft and spongy, stretching and expanding as chicks grow. APARTMENT COMPLEX A sociable weaver nest is a busy place as year-round shelter and warmth for up to 200 birds, with separate entrances and chambers for each family unit.

ADOBE Ovenbirds build a sturdy, enclosed nest of mud mixed with plant matter.

REUSERS In some places, burrowing owls dig their own burrows, but they more commonly settle into a burrow abandoned by a ground squirrel or other rodent, badger, skunk, armadillo, or tortoise. The female owl stays underground with her eggs and chicks, while the male hunts and feeds the family.

COOL AND DRY A monogamous pair of Gila woodpeckers work together to excavate a nest cavity in a dry cactus or palm. The pair reuse the same nest for several years.

Vultures play a vital role in the environment: they are part of the all-important cleanup crew.

hey are not acclaimed for a dulcet song or vibrant plumage. They don’t mimic voices or build fancy nests. They don’t snatch their meals from roiling rivers or hover like helicopters in front of flower blossoms. They have a significant “ick factor” attached to their smelly diet of carrion, and just the word “vulture” engenders fear or revulsion in the hearts of many. In short, vultures don’t get much love. But vultures do plenty to earn their keep in their respective ecosystems, from much-needed tidying up of dead stuff to actually removing pathogens from the environment in ways no other animal can. As the ultimate low-impact consumer, vultures soar thousands of feet above the Earth in search of a tasty carcass. They form strong pair bonds, and both parents help raise the young. Some have wingspans wider than a bus. Many species have colorful faces and beautiful feathers. Looking at them with fresh eyes, there’s a lot to love about vultures!

Unfortunately, “mass poisoning events” in Africa are sounding a death knell for many of these big-bodied scavengers. “People’s perceptions can be a roadblock to saving less ‘cute’ species,” said Jenny Tibbott, senior bird keeper at the San Diego Zoo Safari Park. “But without enough vultures around, who’s going to ‘do the dishes’?”

SOAP OF THE SAVANNA Vultures have earned the term “soap of the savanna” due to their critical role in maintaining healthy ecosystems. By consuming about 70 percent of all available carrion, vultures prevent the spread of diseases like rabies, anthrax, tuberculosis, and botulism. They are immune to the toxins, and their stomach acids are unrivaled! Water sources and soil are less prone to contamination with vultures around, and both wildlife and humans reap health benefits from their “service.”

species rebound, along with hunters using alternative ammunition. San Diego Zoo Global has worked with other organizations to gradually coax this species back from the edge of extinction. In the 1990s, India experienced a dramatic decline in vulture populations, which was eventually attributed to diclofenac, an anti-inflammatory drug used by veterinarians to treat pain in cattle. Hundreds of vultures would descend on a single cow carcass, and cattle recently treated with diclofenac proved fatal for the birds. Without these scavengers cleaning up the carcasses, opportunistic scavengers like crows, rats, and dogs took up the slack, which led to an increase in disease-carrying feral dogs—up to 7 million by some estimates. Since dogs came into much closer contact with humans than vultures ever would, the natural disease

SHOUT OUT International Vulture Awareness Day will be celebrated at the Safari Park September 3 to 5, 2016, with special keeper talks and animal encounters. Soar on over!

PATTERN OF POISON Yet over half of the 23 vulture species—which include California and Andean condors—are threatened or endangered. Africa is home to 11 vulture species, and 7 species are on the brink of extinction. As social birds, vultures are prone to rapid decline from mass poisonings, because a large group of birds can be killed at one time from the same poisoned carcass. The current crisis is not the first time vultures have been under siege from poisons in their environment. In the 1980s, the California condor had dwindled to just 22 birds, largely due to ingesting toxic lead bullet fragments in carcasses left behind by hunters. It has taken decades of collaborative conservation efforts to help this

California condors are a conservation success story, despite ongoing hazards to free-flying birds like ingesting microtrash (inset) and lead bullet fragments in their food sources.

barrier was compromised. It is thought that dogs feeding on disease-ridden carcasses were at least partly to blame for the rabies outbreak estimated to have killed 48,000 people between 1992 and 2006 in India. Fortunately, the country has banned the use of veterinary diclofenac, and it is hoped vulture populations there will stabilize. The recent rapid vulture decline in Africa is tied to the poaching epidemic. Known as the “ranger’s best friend,” the vultures’ circling flight, which is visible for miles, indicates a fresh carcass on the ground below. Vultures are the harbingers of the latest slaughtered elephant or rhino, thus giving rangers a valuable clue. Unfortunately, poachers are also privy to this, and many have started poisoning animal carcasses after they have taken the tusks, horns, and body parts they want. When vultures then descend to feed, dozens of birds are destroyed at a time—along with other scavengers like hyenas and jackals—leaving fewer to “announce” the poachers’ presence. Another threat to vultures is indiscriminant poisoning by farmers. In retribution for livestock being taken by carnivores like lions, farmers leave a poisoned carcass to kill the returning predator. But that tainted cow carcass also attracts

12 / ZOONOOZ / SEPTEMBER 2016

scavengers, and it is just as deadly to vultures as a poisoned elephant corpse left by poachers. Other threats to vultures include habitat loss, collisions with power lines and wind turbines, and the use of their body parts in religious rituals. Additionally, large vulture species have a slow reproductive rate. They reach sexual maturity at five to six years of age, and once they find a suitable mate, the pair only raises one chick every one to two years.

VULTURE CULTURE Over the years, San Diego Zoo Global has worked with 18 of the 23 vulture species. California condors are perhaps the best-known success story, with 207 chicks hatched at the Park and 136 birds released in California, Arizona, Utah, and Baja California, Mexico. San Diego Zoo Global has also played a key role in the breeding and reintroduction of the Andean condor. The first hatching of this species in the US took place at the Zoo in 1942; since then, 29 chicks have hatched at the Zoo and 42 have hatched at the Park. We have collaborated with other zoos to release 80 birds into the wild, mostly in Colombia. Safari Park visitors can see breeding pairs of the critically endangered Ruppell’s vulture and hooded

vulture, as well as the endangered lappetfaced and Egyptian vultures. Breeding these birds in zoos helps to study the species while creating assurance populations that could potentially be reintroduced. Researching and monitoring vultures is a vital step in finding solutions to the current population declines. San Diego Zoo Global supports Ruppell’s vulture research in East Africa; and we are working on wind turbine mitigation in Baja California for the California condor program. Unintentional vulture poisoning by ranchers or farmers is a complicated issue, but that too is being addressed with the help of community conservation groups. San Diego Zoo Global works to combat wildlife trafficking and assists the U.S. Fish and Wildlife Service with communication efforts concerning these crimes, which take a terrible, far-reaching toll on all kinds of wildlife, including vultures.

An Egyptian vulture uses a rock to crack open an egg. Below: The American black vulture patrols highways for easy roadkill meals, but can also fall victim to vehicle strikes.

“Vultures play a key role in maintaining balanced ecosystems,” said Jenny. “As more people become aware of the threats vultures are facing, we can hopefully turn the tide on this crisis.” Without vultures as part of a thriving cleanup crew, ecosystems would become disease-ridden and unstable. And that’s not healthy for any of us.

rominently displayed signs mark the area as a “Quiet Zone,” but the boisterous calls of exotic species sporadically pierce the peaceful surroundings. A blue-bellied roller Coracias cyanogaster breaks into what sounds like raucous laughter. The adamant call of a long-toed lapwing Vanellus crassirostris prompts Andrew Stehly, an animal care supervisor at the San Diego Zoo Safari Park, to interpret: “He’s telling us to ‘keep moving.’” It’s a good sign; the pair inside gets protective when incubating eggs. They have successfully raised three chicks this year, and keepers are hoping for another clutch.

The Safari Park’s Bird Breeding Center (BBC) spreads across nearly four remote acres of Safari Park property. Michael Mace, curator of birds at the Safari Park, explains the goals of the BBC: “This is a place where our dedicated keeper staff conducts behavioral research, assists other zoos around the world with bird information, and raises birds for release into the wild.” Currently, the BBC team breeds 77 species, including 16 endangered species, with 3 of those critically endangered. One, the Guam kingfisher Todiramphus cinnamominus, is extinct in the wild.

SENSITIVE SPECIES “We work with some rare and sensitive species,” says Michael, including birds that haven’t reproduced well in managed care, such as the Storm’s stork Ciconia stormi. This second-rarest stork in the world isn’t well understood, and the BBC is the only place it has successfully reproduced outside of Asia.

work with a wide variety of species, from tiny finches to saddlebill storks that are five feet tall,” says Michael. Enclosures are furnished with water features, live plants, secluded areas for nesting, and a variety of nesting materials—whatever it takes for the birds to feel comfortable.

FINDING SOLUTIONS Creativity plays a role in the success, too. It can be a challenge to figure out just what a species needs, but it’s one that Andrew is always up for. “The more rare and challenging the bird, the more I like it. Anytime we can breed something for the first time, that is something big for us.” It’s often a big deal for other organizations, too. Accredited zoos around the world send birds—especially species that haven’t been successful reproducing elsewhere—to breed at the BBC. In fact, 47 of the species breeding at the BBC represent cooperative efforts managed by both North American and European zoos. “Many of the birds raised here will go to other zoos around the world,” says Andrew. “The protocols we’ve developed for raising these species go with them to other institutions.”

“Sometimes we get really genetically valuable individuals—birds that have never bred,” says Andrew. As much as possible, the keepers manage breeding according to the best genetic matches. But, like people, some birds are pickier than others. The Guam kingfisher has proven to be a challenge. “They’re territorial, so we have to be protective when we put them together,” explains Andrew. So how do you play matchmaker to birds? First, keepers place the birds in side-by-side enclosures and observe them. “We look for positive interactions between them before we put them together,” says Michael. “If a pair isn’t compatible, we rematch them.” Once a pair has bred, and the female lays eggs, keepers hope the parents will incubate them and care for the chicks. Unfortunately, inexperienced parents sometimes aren’t quite sure what to do with an egg or a cheeping chick. Andrew says, “Sometimes we have to intervene, but we try to return the chicks to their parents.” Another option is cross-fostering: placing a precious egg in the nest of experienced parents—even a different species—that will incubate it and care for the chick.

LEAVING THE NEST The next hurdle is the fledging period, as a chick becomes independent. Some human parents welcome their grown children living at home, but the parenting style of species like the crested coua Coua cristata could be described as “tough love.” Although attentive when their chicks are young, once they decide they’ve done their part, says Andrew, “Coua parents encourage their fledglings to leave the nest, so they can lay another clutch of eggs.” That’s a nice way of saying that the parents forcefully chase their chicks out. Coua chicks fledge after just 10 to 12 days, so according to Andrew, “The challenge is that it happens so suddenly.” Keepers found a solution by relocating chicks to a “howdy enclosure” attached to but separate from the parent’s enclosure. Here, the parents can continue to feed and care for their chicks until they reach that potentially risky farewell stage—and then just stop. Using this approach, keepers were able to produce the first crested coua raised in North America, and provide crested couas to other AZA-accredited zoos.

CHALLENGES BRING REWARDS Where habitat is secure, BBC-bred birds like Guam rails and light-footed Ridgway’s rails (for-

merly clapper rails) Rallus obsoletus levipes have been released into the wild. Lead keeper Kristina Heston has participated in releases of the light-footed Ridgway’s rails. “Some of the chicks we’ve raised here have even reproduced in the wild,” she says. In fact, the population of the local wetland species has tripled, in large part due to the efforts of the BBC team. Kristina admits to a special fondness for this species. Endangered and particularly shy by nature, they are difficult to observe, but Kristina keeps close tabs on her charges. Discreet monitoring cameras allow her to observe the natural behavior of the bashful birds without disturbing them. “We see more natural behavior on the video monitors than when the birds see us watching them,” she says. “We get to watch them grow up and then release them locally in marshes— which is very cool,” she says. “One of the most significant benefits of having this off-exhibit collection is that the experience we’ve gained has translated directly into success with endangered species,” says Michael. As one of the most comprehensive off-exhibit bird breeding facilities in North America—and one of the largest in the world—the BBC contributes greatly to San Diego Zoo Global’s vision to lead the fight against extinction.

ALTERING THE FLIGHT PLAN

The New Course for Bird Ambassadors at the San Diego Zoo and Safari Park

or a wild bird, even the friendliest skies can suddenly turn turbulent. Obstacles such as injury, illness, or human interference can cause an unexpected change in life’s route—and it’s often not in the right direction. But for some fortunate fliers, like the rescued ambassadors at the San Diego Zoo and Safari Park, plotting a new course can help their wild brethren by deepening the understanding and respect that people have for nature.

GOOD AS GOLD(EN)

With her 6-foot wingspan, intense gaze, and confident personality, Tonka, the Safari Park’s 18-year-old golden eagle, is worth her weight (9 pounds!) in gold when it comes to impressing visitors. Her story was almost over before it started, however. She was found injured as a fledgling near a trail in the Angeles National Forest in 1998. “We believe she fell out of a cliffside nest,” says Janet RoseHinostroza, an animal training supervisor at the Safari Park. “She was found with a broken hip, and her immature plumage meant she was young.” The hiker who discovered her contacted a park ranger, and Tonka was

taken to a wildlife rehabilitation center. She recovered completely from her injury, but became imprinted on humans in the process, making her unsuitable for rerelease into the wild. “She considers people ‘mouse dispensers,’” Janet explains. “She can’t be returned to the forest, because if she got too hungry or thirsty, she would seek out people for help. That’s not a good situation.” Due to her status as a protected native species, the California Department of Fish and Wildlife keeps close tabs on Tonka. They check in each year to see what she is contributing as an ambassador for her species, and to ensure she has a great quality of life.

THE MINISCULE FALCON The kestrel, or sparrow hawk, is the smallest falcon in the US—but don’t tell that to Safari Park ambassador Rusty. As far as he’s concerned, he’s large and in charge. In 2013, Rusty landed on the shoulder of a horseback rider in Julian, and proceeded to accompany her all the way back to her home. Representatives from the U.S. Fish and Wildlife Service were contacted, and once it was clear how imprinted the little bird was, they contacted the Safari Park. Annette Russell, a lead animal trainer at the Park, works with Rusty and believes his species was a clue to his potential origins. “Kestrels are usually the first type of bird a beginning falconer will use,” Annette says. “They may be small, less than one-quarter of a pound, but they’re strong little hunters— they go after bugs, mice, and lizards.” Rusty is calm and collected during his appearances at the Safari Park, fluffing his

feathers comfortably, and vocalizing occasionally to let people know he’s watching them—and, as Annette says, to ask for his favorite bite-size treat, “meese’s pieces.” That’s exactly what it sounds like, and Rusty thinks they’re delicious.

TENACIOUS TONY Not only is Tony Hawk strong-willed, he’s also incredibly lucky. After fledging in the wild in 2009, the young red-tailed hawk contracted West Nile virus; and when a passerby discovered him, he was assumed to be dead.

Roadkill left on the side of the road can cause the same problems.” Athena adds that meeting these charismatic creatures helps people develop better conservation habits of their own. “Someone might use pesticides or insecticides in their yards, but then birds eat those poisoned bugs,” she says. “The same can happen with the use of rodent poison. By putting up owl boxes, you can attract owls to your yard, and you’ll have your own safe, natural rodent control. It’s better for everyone.” With that type of insight, and a little effort, we can help put wildlife—winged and otherwise— back on the right path.

BIG BIRD For the quirky kori bustard, there’s no business like “show” business. BY ESTON ELLIS | STAFF WRITER

They are big. They can also be loud— and they will not be ignored. They are kori bustards Ardeotis kori, the heaviest flying birds in Africa. Kori bustards are an iconic species in southern and eastern Africa, explained Michael Mace, curator of birds at the San Diego Zoo Safari Park. “This is a species people will often see if they are on safari there.” However, if you live in the United States, you are less likely to see one. The Safari Park has had kori bustards since the 1970s, but few other zoos do. Weighing as much as 42 pounds, standing nearly 5 feet tall, and boasting a wingspan of up to 9 feet, kori bustards are easy to spot. Males are about 30 percent larger than females, but both have a brown back and tail, with white and black spots near the front underside of their wings. Kori bustards are omnivores, feeding on insects, seeds, berries, snakes, mice, and lizards—and they sometimes snack on acacia tree gum.

When they do choose to fly, it’s an impressive sight. “Getting into the air takes so much power,” said Jenny Tibbott, a senior keeper at the Park. Kori bustards have remarkable strength, and their long flight feathers have huge shafts to provide the lift needed to keep this big bird airborne.

LADIES’ CHOICE

WALK ON In their native habitat, kori bustards live in grasslands and wooded savanna. They have long legs and surprisingly small feet, with three forward-facing toes that are built for walking and running. Their elongated legs carry them effortlessly through tall grass—and they prefer to walk rather than fly. “They are very terrestrial, spending most of their time on the ground,” said Andrew Stehly, an animal care supervisor at the Park. “Flying is used more as a means of escape.”

four times its size, puffs up the feathers on his chest, raises his crest of head feathers, lifts his tail feathers to reveal the white feathers underneath, points his wings to the ground, and struts. “It looks as if he has just been turned inside out,” Michael said. The resulting display is visible to birds more than one-half mile away. Even if you missed that display, you couldn’t ignore the male kori bustard’s mating vocalization. It’s a low, deeply resonating bass sound, called booming. “Our birds start booming in November and December,” Jenny said. “You can feel it in your whole body, down to your core—it carries quite a distance.”

YOU CAN’T LOOK AWAY Kori bustards are eye-catching when they aren’t trying to attract a mate, but during mating season, the males put on a remarkable show. In the wild, males gather in a loosely formed group called a lek, competing with each other for the best display to attract a female. The male inflates his esophagus until it balloons to

Females show no obvious interest in the males’ displays, until one coyly decides to lie down near her chosen one. The male will peck gently at her head for a few minutes, followed by mating, and then the two go their separate ways. “It’s the female’s choice, all the way,” Jenny said. “When it comes to mating, the males have to wait for her to decide.” Kori bustards do not form pair bonds, and a male that has just mated may try to interest another female with his elaborate display. Males do not participate in chick rearing. For nesting, the female makes a shallow scrape in the ground, and lays one to two large, blotchy, tan-to-olivecolored eggs. They hatch after about four weeks, and the precocial chicks fledge in about five weeks.

The strutting male kori bustard puts on an impressive mating display. But even when they arenâ&#x20AC;&#x2122;t trying to attract a mate, big kori bustards are eye-catching birds.

Soon after chicks hatch from incubated eggs at the Safari Park, they go on walks with keepers— six times a day.

WHEN 585 MET 588

DID YOU KNOW? Kori bustards have been illegally hunted for their feathers, used to make fly-fishing lures for salmon anglers. However, a conservation program that provides anglers with molted feathers from birds at zoos has helped decrease poaching in the wild.

At the Safari Park, kori bustards share an exhibit in Okavango Outpost with secretary birds and storks. There are currently two adult bustards in the exhibit: female 588 and male 585. “He’s been in our collection for 20 years, but in a subordinate role, until now,” Jenny explained. In the past, when the males were in lek mode, 585’s role was that of a “wingman”—his display only served to get the other males excited enough to compete with displays. When it came to romance, 585 always came on too strong and was quickly rejected. “If the female is submitting, the male responds with gentle head pecks; but his were a little too hard,” Jenny said. However, when 585 met 588, a 13-year-old female that arrived at the Park in 2014, it seemed to be a match made in heaven—or at least in the kori bustard studbook. “When we brought in this female, I thought this is really the one for him,” Jenny said. “She’s a boss: she’s the dominant animal in this whole enclosure. She’ll challenge anyone, from one of the big storks to a secretary bird.”

22 / ZOONOOZ / SEPTEMBER 2016

There was instant kori chemistry! “She’s more confident, more tolerant, and can handle his assertiveness,” Jenny said. After they met and mated, 588 laid her first fertile eggs ever, and these were the first eggs 585 had ever sired. “He’s a wild-collected male, with a lot to add to kori bustard genetics, so we are super excited,” Jenny said.

KORI SURVIVAL It’s uncertain how many kori bustards still exist in the wild. They are listed as Near Threatened on the International Union for Conservation of Nature (IUCN) Red List. But “Wild kori bustards are continuing to decline at an alarming rate,” Michael said. One major contributor to their population decrease is collisions with high-voltage power lines. Despite their protected status, they are hunted as meat, and increased urban development has also affected their numbers. “Koris don’t do well in disturbed areas,” Jenny said. “They don’t like people, and they don’t do well with heavy equipment. They need undisturbed grasslands.”

While adult kori bustards can be prey for predators like leopards, cheetahs, hyenas, and jackals, eggs and chicks are even more vulnerable. One study estimated that 82 percent of kori bustard chicks do not survive their first year. The Safari Park participates in the Association of Zoos and Aquariums’ Species Survival Plan (SSP) program for kori bustards and has hatched 15 chicks since 2002. As part of the breeding program, when a kori bustard female lays an egg in the Safari Park exhibit, it is replaced with a dummy egg, and the real egg is taken to an off-exhibit area for hatching. The hatched chicks are hand raised, taking bits of watermelon, crickets, vegetables, and pellets from tweezers. Not long after hatching, kori bustards start walking. Keepers take the chicks on walks six times a day, and the koris closely follow the keepers’ moving legs. As the chicks grow, they are taken to the Park’s Bird Breeding Center (BBC) until they are almost full grown. There, they meet an adult mentor: a female kori bustard that teaches them what they need to know as adults. “She plays a crucial role in raising chicks,” Jenny said. As adults, the birds are paired by the SSP with potential mates at other facilities. Not many zoos care for kori bustards, because they require a lot of space and specialized care. “Koris need an area free of obstructions, because they frighten easily and may collide with objects and get hurt,” Jenny said. “I wish more facilities exhibited kori bustards, so more people could get to know and appreciate these remarkable birds.”

Happy Birthday, San Diego Zoo! October 2 is the San Diego Zoo’s official birthday, the day that Dr. Harry Wegeforth and four colleagues met and founded what would become an icon of San Diego. To celebrate that momentous day during our centennial year, you are invited to a birthday party event at the Zoo’s Centennial Plaza SUNDAY, OCTOBER 2, 2016. Dr. Harry originally dedicated the Zoo to the children of San Diego, and this year we are following the tradition and dedicating San Diego Zoo Global to the children of the world. There will be fun birthday activities on CENTENNIAL PLAZA STARTING AT 9 A.M., a very special presentation in WEGEFORTH BOWL AT 10 A.M., chances to meet animal ambassadors and costumed characters, and, of course, a spectacular birthday cake and cupcakes (while they last!). Join us for a wonderful commemoration of 100 years of the San Diego Zoo!

The month of October is that great time of year when kids enjoy free admission all month long at the San Diego Zoo and the San Diego Zoo Safari Park! During Kids Free presented by Mission Fed, children 11 years and younger can explore their wild side by meeting our wildlife, with no admission charge, from October 1 to 31, 2016. And on weekends, there will be even more kid-focused fun with special activities.

100 YEARS OF THE SAN Part 8: Expansion, 1987-1996

hen giant pandas Basi and Yuan Yuan came to the San Diego Zoo in 1987 on a six-month loan from China, it was a monumental event for the Zoo—and for San Diego. Two exhibit spaces were constructed side by side for them, in the area that is now at the base of the Zoo’s Sun Bear Forest. It was standing room only as visitors flocked to see the black-and-white bears, and Basi and Yuan Yuan’s visit was extended because they were so popular. By the time they returned to China, they had won the hearts of more than two million visitors. A major milestone was reached at the Wild Animal Park (now Safari Park) in 1988: a California condor chick named Molloko hatched at the Park’s off-exhibit “Condorminium” on April 29. He was the first California condor conceived, hatched, and raised in a zoo setting, an important step forward for the California Condor Recovery Program. Then in 1989, the Park welcomed three members of another endangered species that would also come to symbolize the urgent need for conservation: northern white rhinos Saut, Nadi, and Nola. During the late 1980s and 1990s, the Zoo news (from top): The panda visit in 1987 was a sensation; keeper Don Sterner checks on condor chick Molloko; Polar Bear Plunge created a new home for the bears; Nola, Saut, and Nadi arrived in 1989.

24 / ZOONOOZ / SEPTEMBER 2016

Zoo began a transformation in exhibit planning and design. The new exhibit complexes were termed “bioclimatic zones”: they represented an area of the world and types of habitat, featuring animal and plant species native to that area. Moving away from organizing the zoo by showing one type of animal, like cats or bears, in the same area, the new exhibits sought to depict the diversity of life that makes up a particular habitat, and to provide visitors with a better understanding of the connections between the varied species that live there. The first bioclimatic zone exhibit to open at the Zoo was the Kopje, in 1986. It simulated the boulder-strewn areas found on the African plains, where a variety of plants, smaller mammals, and birds flourish. Tiger River then opened in 1988, representing a tropical Asian forest where tigers, fishing cats, pythons, and storks lived. Tiger River also expanded the concept of an immersive habitat experience, with innovative and interactive interpretation elements. Environmental details were a focus, with walls along walkways that looked like eroded banks with embedded tree roots, and misters that provided a humid, tropical experience. Sun Bear Forest opened in 1989, following the design concepts from Tiger River to create an Asian forest for sun bears, binturongs, and a troop of lion-tailed macaques. On opening day, the energetic sun bears had a field day, showing off just how agile, clever, and strong they were. They made short work of stripping the bark off the carefully chosen tree branches and uprooting and moving the strategically placed logs. They also dug up the square patches of sod that had not taken root yet—much to the dismay of the exhibit and horticulture staff!

In addition to success with California condors, new bioclimatic zone exhibits, and the arrival of giant pandas, the Zoological Society of San Diego was expanding in another way during the 1990s: through technology. By now the advent of the personal computer was making sweeping changes in communication worldwide, and the Zoo delved into creating its first website. This provided opportunities to reach a much broader audience with animal information and conservation messages—to communicate nationally and internationally with those who might never have been to San Diego, but might be interested in supporting the Zoological Society of San Diego’s growing worldwide conservation efforts.

CONRAD PREBYS A TRIBUTE TO A BIGHEARTED FRIEND

BY MARK STUART | CHIEF DEVELOPMENT OFFICER

Who wouldn’t love a kiss from Cabo the sea lion?

Debbie and Conrad enjoyed R•I•T•Z galas and the opportunity to raise funds for their favorite animals.

Conrad welcomed hugs from Churchill the polar bear.

26 / ZOONOOZ / SEPTEMBER 2016

Conrad loved coming to the Zoo. It was a home for him a long time ago when “life wasn’t at its best,” in his words. Conrad said he would watch the polar bears frolic in their exhibit and laugh, and laugh, and laugh. His first major Zoo investment was a large polar bear plush animal that he had to convince the store clerk to sell to him. Later, that polar bear would accompany him on trips around town, seated in his car, especially during the holidays when he traveled throughout the area to deliver Christmas bonus checks to his apartment managers. Conrad loved a good time. His first gift to the Zoo was to secure the best table possible for the Rendezvous In The Zoo (R•I•T•Z) gala in 2007. Debbie Turner and Conrad became R•I•T•Z gala mainstays. Debbie and Clarice Perkins chaired one of our most memorable R•I•T•Z galas— with its own improvised moon!— that provided significantly for the Safari Park’s future tiger exhibit. One of my favorite memories with Conrad was in October

2012 when he hosted “Breakfast at Conrad’s” at the Conrad Prebys Elephant Care Center. Conrad invited a group of friends to breakfast at the Zoo. We started by unveiling a neon sign that read “Conrad’s” and featured three fluorescent pachyderms. Before the breakfast, Conrad asked me what he should talk about. I responded, “How about telling people why you love the Zoo?” He did so brilliantly. He ended his remarks by exclaiming the Zoo was the “happiest 100 acres for people and animals on Earth.” Of course, he was right. At the end of that breakfast, Ernest Rady turned to Douglas Myers, the Zoo’s president/CEO, and said, “If Conrad Prebys loves you this much, I should get to know you better.” From Conrad’s introduction, Ernest Rady joined the Zoo family, contributing one of our largest gifts ever. In short, Conrad Prebys left the San Diego Zoo a much more remarkable place, and an even more world-famous institution, than he found it. He will be profoundly missed but proudly—and lovingly— remembered.

Conrad’s generosity made possible the engaging renovations to Polar Bear Plunge, created the world’s greatest elephant care center, and allowed us to build and endow the largest koala exhibit outside of Australia. He was also the first donor to invest in Africa Rocks, our biggest exhibit project ever.

Kagu Curiosity In 1942, a rare kagu came to the San Diego Zoo via the U.S. Navy—a gift from New Caledonia. A Navy chief and two WAVES personally escorted the bird to its new home. TODAY AT THE ZOO Still unusual in zoos, the kagu continues to be part of the San Diego Zoo. You can see a pair of these endangered birds in the aviary next to the Bus Tour loading zone. Look for a flash of their beautiful blue-gray color!

28 / ZOONOOZ / SEPTEMBER 2016

A KAGU ARRIVES—by Belle Benchley We are sure that many of our readers will recall a news item that was broadcast rather recently to the effect that the government of New Caledonia had presented to our famous Admiral William H. Halsey in command of the Fleet in the South Pacific, a bird called a Kagu. Perhaps this meant little to the average person, for, if anyone knew it was a bird from the news reports, it probably was to them “ just another bird” and its real significance remained vague. But to anyone connected with the bird department or the administration of a zoological garden the story was most significant. Such a person would immediately realize that as a mark of their appreciation and esteem the officials of New Caledonia were presenting Admiral Halsey one of the rarest gifts and the most precious in their estimation that they could bestow upon anyone.... So when I received a letter from my friend Lt. John Burke with copies of notes from Admiral Carney saying that he had forwarded the Kagu to Burke to be relayed to us here at the zoo in San Diego as soon as possible, our first feeling was that of jubilation and very sincere and deep gratitude to Admiral Halsey.
