Big News For Big Birds

Condor in Flight

Condors are certainly big news at Oakland Zoo right now with the recent arrival of the first two birds at the newly-opened Steve and Jackie Kane Condor Recovery Center. As you may know, condors are the highly endangered cousins of the vultures that you see in the skies all over California. And like vultures, condors play a vital role in the ecosystem by feeding on the carcasses of dead animals. When these animals are shot by hunters or ranchers, the lead pellets in turn are ingested by the condors. It takes only a tiny fragment of lead to make a condor very ill. These lead-poisoned birds need medical care in order to survive, which is where the zoo comes in. For the past three years we’ve been working with the Ventana Wildlife Society near Big Sur, California, an organization that has been leading conservation efforts to save the California condor for decades. When a sick bird is spotted in the mountains around Big Sur, it’s carefully captured by Ventana’s condor vets and conservationists and brought to our facility. Once here, it’s treated by specially-trained Oakland Zoo veterinarians who provide treatment for the condor until it is healthy enough to be released back into the wild. And you’ll be happy to know that one of the aforementioned birds has already gotten a clean bill of health and has been returned to her home!
But there’s more to our condor program than medical procedures. In April, a small group of young zoo volunteers had the opportunity of attending a special camp about condors. Held at the research facility within the Ventana Wilderness Area, Condor Camp is a 4-day program that lets people observe and participate in the conservation work being done by the Ventana Wildlife Society. This was the first time kids from the zoo (both Teen Wild Guides and Teen Assistants) had the chance to participate in this exciting program. Over the four days they went on a night walk, spotted condors that were feeding on dead seals and sea lions at the Pacific Ocean, and visited the feeding slope and re-release cages used by the staff. They also got to check out the Condor Cam, the remotely-controlled video camera that allows visual monitoring of the birds from the research center. But most exciting, the kids got to use the radio antennas and other equipment to locate the condors, some of whom regularly migrate between Ventana and their other stronghold at Pinnacles National Monument.

And then there’s Condor Class. An educational program for middle and high school students, this half-day class held at Oakland Zoo is an on-site version of the new interactive Field Biology Workshops. The 20-30 students (from science classes at a variety of local schools) get the chance to use the high-tech tools of biologists, such as telemetry equipment and GPS units to track the birds, which all have ID tags and their own individual radio frequencies. The students practice with this equipment by finding hidden stuffed animals, study condor data gathered in the field by biologists and make scientific recommendations for the birds’ welfare based on that data.
So as you can see, there’s a lot of condor activity going on at Oakland Zoo these days. Although the birds here aren’t available for public viewing, you can be sure they’re receiving the medical care they need to get them back out in the wild as soon as possible, thus helping to ensure their continued success in returning from the brink of extinction!

Celebrate Earth Day with a Party for the Planet!

by | March 25th, 2014

Imagine you and your family and friends on a beautiful spring day dancing to live music, building with pine cones, learning to juggle,  meeting your next feline or canine family member and having a ball all while helping the planet? This is how Oakland Zoo celebrates Earth Day!Earthday 2007_123

Humans around the globe have been celebrating their connection to and reverence of the planet for centuries. It makes sense that our modern society would create a day such as Earth Day: a special day set aside to appreciate and take action for our one precious planet. Earth Day was first officially celebrated in the United States in 1970, and is now celebrated in nearly 200 countries each year.

Oakland Zoo also feels that the Earth is indeed something to celebrate, and therefore we produce one of the largest Earth Day events in the East Bay.  This year our event is on Saturday, April 19th and we are calling it a Party of the Planet.

Earth Day fits our mission perfectly: To inspire respect for and stewardship of the natural world while creating a quality visitor experience. What could be more inspiring than making a genuine connection with over fifty visiting organizations who work to help animals and the environment?  Other inspiring experiences will include creating with natural objects in the Create with Nature Zone and making beaded necklaces that help the lives of people and chimpanzees. Quality experiences will be had by all, such as a full day of educational shows in the Clorox Wildlife Theater with live animals, the Jug Bandits Band and Wildlife Action Trivia. Quality fun will be bountiful the meadow with our giant earth ball, circus antics, face painting and a real trapeze show with Trapeze Arts.

Other highlights of Earth Day include: a free train ride with donation of used cell phone or ink cartridge, voting for your favorite conservation project at the Quarters for Conservation voting station, Oakland Zoo docent and eduction stations, and of course, visiting our resident animals.

To further walk the talk, Oakland Zoo will be hosting our monthly Creek Crew clean up of Arroyo Viejo Creek on the grounds from 10:00 AM – 1:00 PM.DSCN1072

We are thrilled to welcome the following organizations to join us this year: 96 Elephants, Africa Matters, All One Ocean, Amazon Watch, Amboseli Trust for Elephants, Animal Rescue Foundation, Aquarium of the Bay, Bay Area Air Quality Management District, Bay Localize, Bay Area Puma Project, Budongo Snare Removal Project, the Borneo Project, California Department of Fish and Wildlife, California Wolf Center, Circus Moves, Cheetah Conservation Fund, Create with Nature Zone, East Bay Co-Housing, East Bay SPCA, Eco-Viva, Go Wild Institute, Handsome in Pink, Kids for the Bay, KQED, Marine Mammal Center, Marshall’s Farm Honey, Mickaboo Companion Bird Rescue, Mickacoo Pigeon and Dove Rescue, Mountain Lion Foundation, Mountain Yellow Legged Frog Project, Northern Light School, Oakland Veg, Pachas Pajamas, Performing Animal Welfare Society, Pesticide Free Zone, Project Coyote, Rainforest Action Network, Red Panda Network, Reticulated Giraffe Project, River Otter Ecology Project, Samasheva, Save the Frogs, Savenature.org, Stopwaste.org, Sulfur Creek Nature Center, San Francisco Seafood Watch Alliance, Uganda Carnivore Program, Trapeze Arts, Ventana Wildlife Society, WildAid and the Western Pond Turtle Project.

You will need a full day to experience all this inspiration and fun! We hope to see you out there on April 19th!

It Takes A Village: Hope for Mountain Lions

by | March 3rd, 2014

What a primal joy to awake each morning on the east side of the Bay Bridge in the beautiful Bay Area and know that somewhere up in the hills, quietly walking, sleeping, purring or chirping, caring for cubs, or hunting –  are lions. Lions! Known as mountain lion, cougar, puma and panther, the elusive “cat of one color” has inspired more names—40 in English alone— than any other animal in the world. The mountain lion is the biggest wild cat in North America and has the largest geographic range of any carnivore in the Western Hemisphere.  Mountain lions can be found from the Yukon to the southern Andes. Here in the Bay Area, lions are known to roam the Santa Cruz Mountains, and varies ranges in the East Bay, near me.

Chris Wilmers, a professor of environmental studies at the University of California Santa Cruz, is leading a team of scientists on the so-called Bay Area Puma Project, which hopes to tag mountain lions to study their movements, range, habits and physiology.

Chris Wilmers, a professor of environmental studies at the University of California Santa Cruz, is leading a team of scientists on the so-called Bay Area Puma Project, which hopes to tag mountain lions to study their movements, range, habits and physiology.

Our mountain lions are much different than African lions in that they are solitary and maintain territories that average 100 square miles in size. Males are highly protective of their large domains and will fight to defend it. A fortunate mountain lion can live a 10-12 year life in the wild. They eat deer and other small mammals which helps keep ecosystems balanced and healthy.

The status of mountain lions is very much in question. Though true populations in the United States, Mexico, Central and South America is virtually unknown, experts estimate 30,000 in the United States. Per the Mountain Lion Foundation’s sources, the California’s statewide population of mountain lions is approximately 4,000 animals and dropping.

As mountain lion habitat is increasingly fragmented and movement corridors are blocked by human development, more sightings and encounters with mountain lions are causing challenges.  Mountain lions are being killed more often by cars and depredation permits (issued when livestock or pets are attacked), and increasing news reports of mountain lion encounters are driving growing public concern for both people and the cats.

As the Conservation Director at Oakland Zoo, I work very closely with wildlife conservation issues all over the world, and habitat loss and the resulting human-wildlife conflict is a challenge we all share, whether that is elephants, tigers, African lions or our own apex predator. I have learned that it takes all stakeholders coming together to truly offer hope for these species.

Now, for the good news: in the Bay Area, mountain lions have friends. One of these friends is the Bay Area Puma Project, who is bringing their international cat research expertise home to the East bay with the aim of understanding these cats and improving our local co-existence with them. Oakland Zoo supports these efforts (they were our Quarters for Conservation project in 2013) and is excited to share their expertise with our public on March 5th at our Conservation Speaker Series event, Saving the Puma.

Other advocates are the Mountain Lion Foundation, the East Bay Regional Park District, and the California Department of Fish and Wildlife, to name a few.

On New Year’s Day, Senate Bill 132 went into effect, which allows the California Department of Fish and Wildlife to work with nongovernmental groups in capturing, tranquilizing or relocating the animals. With this new bill, and the new and improved policies of the California Department of Fish and Wildlife, wardens and their supporting organizations will capture or scare off mountain lions unless they pose an imminent threat to people or public safety. Oakland Zoo is honored to help with this progressive effort.

In fact, Oakland Zoo has embraced mountain lion conservation in many ways. As we join forces with the California Department of Fish and Wildlife, we are committed to both participate in response to mountain lion conflict calls, and to offer care for a mountain lion in need of recovery before it is hopefully released back into the wild. We are also assisting the Bay Area Puma Project with their vital research and launching various outreach and education programs to create greater mountain lion awareness.

What a joy to look out into those hills and feel thanks to working alliances, our own conservation village, there is hope for a peaceful co-existence with our very own native lion.

Oakland Zoo & Local Conservation

by | February 25th, 2014

As a leading presence in a community that attracts more than 700,000 visitors each year, Oakland Zoo strives to bring attention to important concerns in the field of wildlife conservation. For many years, the Zoo has demonstrated its ability to move forward in addressing these concerns. As one of our guiding principles, this commitment to conservation can be seen right here in Oakland, where we’ve initiated a variety of programs within the Zoo and surrounding Knowland Park to help preserve native species of plants and animals. Through our docent program, community outreach, and ongoing Conservation Speaker Series, we’re able to provide the public with relevant messages about species, alert them to the various conservation projects that the Zoo is involved with, and give practical tips on how they can help. Like the roots of a tree, these local efforts branch out in a regional and state-wide scope. Partnering with conservation organizations throughout California, Oakland Zoo supports projects that provide maximum results with the available resources.

Oakland Zoo’s commitment to native species and wildlife is showcased in several programs currently underway:

Western Pond Turtle Head-start Program: The Western Pond Turtle is the only native aquatic turtle in California. Oakland Zoo, in conjunction with Sonoma State University and the San Francisco Zoo, began the first Western Pond Turtle head starting program in California. Through a combination of raising and releasing hatchlings, research, in-field studies, and education, this partnership seeks to further understand and support the reintroduction of this shrinking population. To date and through this conservation effort, Oakland Zoo has helped reintroduce more than 500 Western Pond Turtles into the wild.
Biodiversity Center: A new Zoo facility focused on conserving California species. In August of 2013, this 2,000 sq. ft. complexwas opened and is dedicated to small animal research, rescue, and rehabilitation while incorporating educational programming and interpretive messages on how to conserve native wildlife. The California Biodiversity Classroom will educate visitors on the crucial interdependence of plants, animals, people, and the environment as well as the importance of becoming responsible stewards of California’s rich natural heritage through hands-on, interactive scientific research activities including “citizen science” projects, habitat restoration, and field biology workshops.
Mountain Lion Response and Care: Oakland Zoo, working in partnership with various agencies, including the California Department of Fish and Wildlife, provides support to respond to mountain lion conflict incidences in the Bay Area. The Zoo offers the program staff expertise, capture and dart equipment, and a state of the art veterinary facility to care for and rehabilitate a mountain lion until its release back into the wild.
Mountain Lion Research: Through a partnership with the Bay Area Puma Project, our skilled staff is working in the field to better understand the behavior of mountain lions with the goal of learning to better co-exist with this apex predator.
California Condor: As part of the California Condor Recovery Team and in partnership with Ventana Wildlife Society,  Zoo staff members are trained in field research and the vital medical treatments these awe-inspiring birds need to recover from lead poisoning. The Zoo has built The Steve and Jackie Kane Condor Recovery Center, a facility specifically designed to treat the massive sized birds, where chelation treatment on the birds can be conducted by our veterinary staff. Oakland Zoo’s Education Department  has also developed extensive student programming around this highly endangered species, which includes field studies and classroom research.
Mountain Yellow–Legged Frog: In partnership with  with Vance T. Vredenburg, Ph.D and San Francisco State University, this program involves the support of field work, conservation efforts and treatment procedures to save this species of frog from Chytrtid Fungus. Through research focusing on resistance to the fungus, the future goal is to breed and reintroduce captive bred froglets back to their natal lakes and streams.
Butterfly Conservation Initiative: Oakland Zoo, a founding member of the BFCI, has contributed to its success in a number of ways, most notably with the debut of its Barbara Robbins Memorial Butterfly Garden in May 2003.

Restoration of Local Creek Watershed: In 2008, the Arroyo Viejo Creek restoration project included creek restoration, extensive removal of non-native plants, re-planting of native plant habitat, six new outdoor classrooms with seating made from eucalyptus trees felled at the site, interpretive signage, and a connecting trail. Currently, Oakland Zoo’s Volunteer Creek Crew meets monthly to steward this stretch of the Arroyo Viejo Creek.

Earth Day: Oakland Zoo’s “Party for the Planet” is celebrated at Oakland Zoo as a means to offer our many partners and colleagues in the environmental and wildlife fields a forum to interact with 5,000 zoo visitors on Earth Day. It is also an opportunity to build relationships that share the mission of conserving the natural world.

Local Seed Stock for Native Grassland Protection: In 2012, more than 40,000 native Knowland Park seeds were gathered in order to germinate, create a reserve, and replant areas around our new Veterinary Hospital and in Knowland Park.
Long-Term Commitment to Habitat Enhancement in Knowland Park: In 2011, Oakland Zoo developed a comprehensive Habitat Enhancement Plan for Knowland Park and the future “California Trail.” Habitat enhancement will be achieved through the control and eradication of invasive species and the subsequent re-vegetation of native ones.
Conservation Speaker Series: This series of evening lectures provides the opportunity for the public to meet and hear leading scientists and researchers in various areas of local and worldwide conservation. Upcoming topics include saving the mountain lion and California condor.
Quarters for Conservation: By involving Zoo guests in the voting process, this program allows them to choose how their money is used for conservation programs in the field, be it the Uganda Carnivore Program, helping the Reticulated Giraffe or the saving the highly endangered Mountain Yellow-Legged Frog.

Here at Oakland Zoo, we’re proud not only of our many ongoing conservation efforts but also the dedicated staff members who help support them. Among our many skilled educators, veterinarians, fundraisers, marketers, volunteers and animal care professionals, all are enthusiastic about participating in the efforts to protect these native species. One look out the window of the offices or a quick stroll through the park can reveal an abundance of wild turkeys and deer, with regular sightings of foxes, skunks, herons, egrets, hawks and many other birds. The presence of these native wild animals illustrates quite simply how two worlds often thought to be separate from one another can easily co-exist side by side.

 

 

The Lions of Oakland Zoo…Sandy & Leonard

Sandy and Leonard as cubs in 2000

 

If you’ve been to the Zoo, you’ve likely seen Sandy & Leonard, lounging around in their expansive exhibit, soaking up the sun or enjoying some animal enrichment their loving ZooKeepers so carefully laid out for them earlier that morning. Their presence is awe inspiring, to say the least. It’s hard to believe it has been almost one and a half decades since they arrived here as cubs at Oakland Zoo.  Many people don’t know the history of these two- siblings, actually- so we’d like to share their story with you.

They were the first rescued lions to be placed in a zoo by the Houston SPCA. It was July, 2000 in Crockett, Texas.  Police entered a suspect’s property on an unrelated warrant and found 14 exotic cats and a wolf. Houston SPCA seized all the animals and was given custody of them after the owner had been found to have cruelly treated the animals: depriving them of necessary food, care, and shelter. Two of the cats were 4-month old lion cubs; they were starving, dehydrated, flea ridden, and their coats were patchy and dry.  The Houston SPCA provided them with housing and veterinary care and a month later, they arrived to us, via Continental Airlines, here at Oakland Zoo.

Thus named “Sandy” and “Leonard” the two resided in our Veterinary Care Center while they gained weight and strength. At the time, the Zoo already had an established lion pride, so a separate outdoor holding area was constructed adjacent to the existing lion exhibit, called ‘Simba Pori’.

As the cubs grew, ZooKeepers began plans to introduce Sandy and Leonard to our four resident mature lions, Victor, Marika, Sophie and Maddie. In January 2001, Sandy and Leonard moved up to the lion night house. The introduction and integration of the lions had moderate success. The youngsters did well with our adult male, Victor, and one adult female, Marika, but the other two females did not appreciate their presence.  As with domestic cats, you never know how felines will get along! We took our cues from the lions’

behaviors and decided to manage the lions as separate groups. Over the years, in 2010, the older lions succumbed to age-related illnesses (2 from kidney disease and 2 from cancer). So, today, Sandy and Leonard have taken ownership of the lion exhibit, the night house, and the hearts of staff, ZooKeepers and guests alike.

While their beginnings in the exotic animal trade surely could have destined them to a life of cruelty, we were fortunate to have been able to provide them with a safe and forever home here at the zoo.

Conservation On-Site: The Mountain Yellow-Legged Frog

by | January 29th, 2014

As you visit Oakland Zoo this winter and spring you may notice that the animals and projects we are supporting at our Quarters for Conservation booth in Flamingo Plaza have changed.   I would like you to pay special attention to the developing partnership with the San Francisco State University Mountain Yellow-Legged Frog project.   This project teams up Oakland Zoo with San Francisco State University in bringing awareness to and supporting the recovery of this critically endangered species that is found right here in the mountains of California.

Yellow-legged_frog_Point_Reyes

Once one of the most numerous species found in their alpine habitat in the Sierra Nevada, Transverse, and Peninsular ranges they are now one of the rarest despite this habitat being found in some of the most well-managed and inaccessible areas of the state.    During some of the initial research looking into this decline the focus was on the impact and removal of game fish that were introduced to their alpine habitats, such as trout.   The Mountain Yellow-Legged Frog evolved in a habitat where such efficient predators were not common and the eggs, tadpoles, and frogs themselves became easy prey.  With the management and removal of these introduced fish species some areas showed rapid recovery of frogs.    However, some did not, and in fact the overall population continued to decline.    The emerging disease known as the chytrid fungus (Batrachochytrium dendrobatidis) was found to be the cause of this continued decline and was attacking the frogs during one of their most sensitive transitions in life, the one between tadpole and juvenile life stages.    The chytrid fungus works by attacking the keratin in the skin of juvenile and adult frogs preventing them from being able to use their skin to respirate and exchange water leading to their deaths, wiping out whole populations.   For some reason the disease does not affect the tadpoles of the Mountain Yellow-Legged Frog, but it will remain with them through the several years they spend as a tadpole.    This makes the tadpoles, along with several other frog species that are not affected, a means to not only infect their own kind with this deadly fungus, but to make it almost impossible to eliminate from the environment.

With this revelation the focus to save the Mountain Yellow-Legged Frog changed to not only manage and remove non-native fish, but to support the frogs in gaining resistance to the chytrid fungus during this transition in their life.   The support comes in the form of a bacterium called Janthinobacterium lividum.    The bacteria was discovered on the skin of a fellow amphibian, the red-backed salamander, and later discovered to also be present on the skins of Mountain Yellow-Legged Frog in varying levels.   This bacterium has the unique feature of having anti-fungal properties and when found in greater numbers on amphibian skin can help to increase resistance to the chytrid fungus.    Now, in steps Dr. Vance Vredenburg and the San Francisco State University Mountain Yellow-Legged Frog Project.   Dr. Vredenburg has been pioneering skin bio augmentation treatments using Janthinobacterium lividum to support juvenile frogs that are being rereleased or will be re-released into their habitats in both Northern and Southern California.     Through a partnership with San Diego Zoo, San Francisco Zoo, and soon Oakland Zoo, San Francisco State University is hoping to tip the balance for these frogs by collecting them as eggs from their habitat, hatching them in captivity, raise them to juvenile frogs, treating them with this anti-chytrid bacterium, and release them back into their natal ponds and streams.   It is hoped that not only will this prove to provide long term resistance to chytrid, but will be naturally passed between frogs as they naturally congregate together in the shallows off the banks of the rivers and lakes they live.

If you are interested in learning more about the plight of the Mountain Yellow-Legged Frog and supporting them as well during their most vulnerable transitions you can join us on Wednesday February 5th at 6:30 p.m. in the Marian Zimmer Auditorium at our Conservation Speaker Series event when Dr. Vance Vredenburg joins us to discuss his work with the Mountain Yellow-Legged Frog and the implications his research has to save this and potentially numerous other amphibian species worldwide.
