The Louisiana Pine Snake Species Survival Plan is one of more than 30 field conservation projects in 50 countries around the world supported by Woodland Park Zoo. Here is an update from the field by one of the conservationists working to return Louisiana pine snakes to the wild… Posted by: Steve Reichling PhD, Memphis Zoo Curator and Woodland Park Zoo conservation partner Repatriating the Louisiana pine snake to the eastern portion of its historic range, 50 years after its extirpation, progressed further this August with the release of three more hatchlings. These are especially important snakes because they are carrying externally attached radio transmitters which will allow us to keep tabs on them, at least for a short while, and thereby learn a little about how they are adapting to their environment. Early in the morning, I met staff biologists and rangers who work in the Catahoula District of Kisatchie National Forest, which is where our reintroduction is taking place. The potentia

Posted by: Rebecca Whitham, Communications With five chicks hatched in April, we were thrilled with the breeding success of our endangered Humboldt penguin colony in just the first year of their new exhibit. Well, now there’s even more to cheer. Two more penguins just hatched at the start of August! The keepers regularly weigh the chicks to ensure they are achieving acceptable weight gains. At the weigh-in today, the 12-day-old chick came in at just over 1 lb and the 9-day-old chick at 0.6 lb. They looked healthy and it seems their parents, 18-year-old mother Cujo and 20-year-old father Oedipus, are properly caring for them in their off-exhibit nesting burrow. The parents are among the oldest penguins in the zoo’s colony and also the most genetically valued breeding pair at the zoo. As part of our work in the Species Survival Plan for the endangered Humboldt penguins, ensuring such genetic diversity is critical to the stability of the population. The two chicks will stay under the car

Posted by: Rebecca Whitham, Communications The endangered snow leopard is elusive and hard to study in the wild. So researchers with the Snow Leopard Trust , a Woodland Park Zoo conservation partner , are testing with us a new method of luring these felines to research sites—Calvin Klein Obsession for Men. Today, we tested the appeal of the cologne on our 1-year-old cubs Gobi and Batu, and their mom Helen. We installed a camera in the snow leopard exhibit and sprayed the cologne around the area of the camera in hopes of capturing stop-action images and measuring the reaction of the cats to the lavender, spice and woody elements of the cologne. The results? Well, we wouldn’t quite call it an obsession, but the cats are definitely interested in Obsession. The cologne proved to be a strong attractant…eventually. It just took the cats several minutes before they caught the scent and became interested in it, rubbing up to the areas where the scent was splashed. The novelty of the camera in

Posted by: Jim Bennett, Marketing His ultimate vision is to construct a semi-closed system aquaponic operation behind the zoo’s Rain Forest Food Pavilion, raising trout and cycling the waste to grow herbs and salad greens. The herbs would be used in Lancer Catering’s food service operations; the trout as treats for the zoo’s penguins. And no packaging or shipping would be needed to get the food to market. Far fetched? I talked to executive chef Brandon Bretz and general manager Maureen Gulley of Lancer Catering, Woodland Park Zoo’s food concession partner, about how they help the zoo source food locally to minimize their carbon footprint . While aquaponics is an amazing vision worth exploring for the future, what Lancer does right now is remarkable in its own right. Fish served at the zoo’s Pacific Blue Chowder House is sourced locally from Ballard Seafood using updated guidelines from Seafood Watch . Produce is also brought in from local growers via Charlie’s Produce. Bretz doesn’t j

Posted by: Rebecca Whitham, Communications Yesterday our 3-year-old, female red panda underwent a full physical examination by our animal health team as part of our preventive care program for all animals at the zoo. The routine check-up included a weigh-in, blood work and radiographs. The healthy red panda came in at 27 pounds. As part of our efforts in the Red Panda Species Survival Plan, this female will be paired with our 6-year-old male in an off-view area for their upcoming breeding season in the winter. Since these two have never had any offspring before, their genes are particularly valuable to maintaining genetic diversity in the red panda population. In the wild, fewer than 10,000 red pandas remain in their native habitat of bamboo forests in China, the Himalayas and Myanmar. Their numbers are declining due to deforestation, increased agriculture and cattle grazing, and continuing pressure from growing local populations. We can all do our part to help reduce our impact on wil

Posted by: Rebecca Whitham, Communications Zoo Corps teen interns Garrett Brenden and Ariel Thompson stood at the edge of a pond in a south Puget Sound protected wildlife area yesterday and released from their hands something precious…hope for the endangered western pond turtle. Garrett (shown above) and Ariel have been working alongside zookeepers to raise 76 western pond turtles behind the scenes at the zoo as part of a headstart program to recover their wild population. Turtle hatchlings are collected from the wild then raised here until they are around 2 ounces—large enough to escape the mouths of bullfrogs and large-mouth bass—giving them an edge on surviving in the wild. Each summer, we take trips to several protected wildlife areas and release these headstarted turtles back into the wild where we continue to monitor them. Since starting the program in 1991, we’ve seen the population of western pond turtles grow from a dangerously low 150 to now 1,500—a positive sign that this c

Posted by: Kathryn Owen, Education When it comes to enjoying fresh fruits and vegetables, what could be better than being able to pluck a ripe tomato or crisp head of lettuce out of your very own garden? For Woodland Park Zoo’s gorilla troops , fresh-off-the-vine produce is just that accessible. In the winter they may be dining on evergreen elaeagnus leaves, and in the summer they may be stuffing themselves with grape leaves and tender vines. A wide variety of animals at the zoo enjoy fresh produce from the zoo’s browse program, which provides fresh leaves, stems and flowers for gorillas, red pandas, colobus monkeys, orangutans, elephants, tree kangaroos and many others. You and I use the term “browse” to mean sampling and exploring—like browsing the shelves of a bookstore in search of something appealing. But the term also refers to the plant materials eaten by browsers—that is, herbivores or plant-eaters that eat the leaves, stems and flowers right off the tree or bush instead of gra

Posted by: Bobbi Miller, Conservation While we celebrate the hatching of our new red-crowned crane here at the zoo, our Partner for Wildlife Sergei Smirenski of Cranes of Asia reminds us of just how precarious the balance between habitat and population is in the wild. Recently he told us of a devastating fire that burned through 90% of Muraviovka Park, a protected area of critical crane habitat in the Russian Far East. The Amur region of Russia is an important nesting ground for the endangered red-crowned crane. Muraviovka Park was established in part to protect the diminishing wetlands which serve as a critical habitat for the crane, with an estimated population of only 2,700 left in the wild. Due to an ongoing drought, fires started by hunters or nearby farmers can present a potentially habitat destroying event that takes an already endangered species even closer to the brink. And that is exactly what happened on the afternoon of May 2 when smoke appeared on the horizon. According

Posted by: Ric Brewer, Communications If you've been to our Tropical Rain Forest building, you have no doubt been drawn to the lustrously-maned little monkey from Brazil, the golden lion tamarin . But did you know that these primates are ambassadors for one of the most well-documented and inspiring stories of conservation success in the wild? It goes back to the late 1970s, when population surveys conducted in tamarins' shrinking rain forest habitat located along a sliver of coastal Brazil discovered that these vibrantly colored primates were in severe decline: only 200-600 still existed in total and with the continued destruction of their habitat, their extinction looked imminent. But a consortium of zoos , including Woodland Park Zoo, banded together to captive-breed and release genetically diverse golden lion tamarins back into Brazil, along with creating habitat protection plans to ensure there would be places for them to grow their population. Woodland Park Zoo contributed

Posted by: Ric Brewer, Communications Did you ever wonder what it takes to provide food for the nearly 1,100 animals at Woodland Park Zoo? How does the zoo provide nutritionally balanced and natural diets that range from hundreds of pounds a day of hay for the elephants, oryx, gazelles and other animals to nettle leaf powder for our Partula snails? Where does it all come from? With nearly 300 different animal species, our staff works hard to provide all the animals with the opportunity to display natural behaviors, which includes replicating as closely as possible what they would eat in the wild. But there's even more to it than finding just the right veggies, fruits and other foods. When planning the diets for our animals, three factors are taken into consideration: 1) what is the best, nutritionally balanced diet for this particular species? 2) are those foods available? 3) can we find this food locally? What is the impact on our carbon footprint? Are we always able to make all

Posted by: Rebecca Whitham, Communications Our not-so-tiny-anymore snow leopard cubs Gobi (now 65 lb) and Batu (now 56 lb) turned 1 year old this week! We celebrated their birthday with two incredible paper-mâché “cakes” for the cubs made by one of our very talented staff members (Thanks, Regina!). Keepers put the cakes out into the exhibit space while the cats were behind the scenes. But once the snow leopards came out, it took just seconds for them to spot and sniff the fun, new enrichment in their exhibit and pounce! The crowd of school kids and visitors encouraged them with chants, “Get it! Get it!” And they all thrilled to see mom Helen and the cubs stomp, bite, shred, and roll those cakes down the hill—leaving quite a mess behind! But what’s a birthday party without a little mess? We’ll continue celebrating Gobi, Batu and the majestic species they represent with our annual Snow Leopard Day event coming up on August 14. The cubs were born last year as part of the Species Surviva

Posted by: Rebecca Whitham, Communications The pudu is the smallest deer in the world. A baby pudu then is, well, tiny. See for yourself: This tiny pudu female was born over the weekend at the zoo and we joined the vets, keepers and members of the press today for the neonatal exam of the baby. It was a quick exam that went well, and then baby rejoined her mother back on exhibit near the flamingos in the Temperate Forest area of the zoo. You can see them out on exhibit now, though you’ll have to look closely as these small babies are often well concealed by their mothers to protect them from predation. Not familiar with this animal? The pudu, pronounced POO-doo, is the smallest deer in the world, native to South America. At the zoo, we house southern pudus, which range in the wild throughout the lower Andes of Chile and southwest Argentina. Natural habitat for the endangered pudu continues to diminish due to overpopulation, clearing of land for agriculture, logging, hunting and other h

Posted by: Bobbi Miller, Field Conservation Never heard of the Louisiana pine snake? Maybe that’s because it is the rarest snake species in North America. The Louisiana Pine Snake Species Survival Plan (SSP) is one of the newest conservation projects the zoo is helping to fund and support. The program aims to return the snake to central Louisiana after a 60-year absence. In fall 2009, scientists conducted on-site inspections of five potential release sites and eventually selected a location in the Kisatchie National Forest that would provide an appropriate habitat for the reintroduced population and its future offspring. Zoos that are participating in the SSP are helping by breeding these snakes to produce offspring for eventual release, with the goal of releasing 40 newly hatched Louisiana pine snakes in 2010. The next step is then to monitor subsets of the snakes released using radio-telemetry to learn more about how the animals are surviving, what their home range is like, and how

Posted by: Rebecca Whitham, Communications Here's the first video of the newly hatched Humboldt penguin chick. Turn up the sound to find out what the keepers are looking for during this quick checkup: And here's some exciting news--this chick now has a sibling, hatched on Easter Sunday! Penguin keepers are weighing the chicks each day for the first week after hatching to ensure acceptable weight gains while allowing the parents to raise their chicks and gain experience as parents. In zoos and in the wild, both penguin parents take turns incubating the eggs and caring for their young. It will be early summer before the penguin chicks emerge from the nesting burrows and venture outdoors into the public exhibit. We'll post updates periodically as the chicks grow. Video produced by Ryan Hawk, narration by Katie Norton/Woodland Park Zoo.

Posted by: Gigi Allianic, Communications As we shared earlier this week , Easter has delivered an early batch of eggs to Woodland Park Zoo – Humboldt penguin eggs, that is – and the first chick was discovered to have hatched on April Fool’s Day! The first penguin chick represents the first offspring for mother Dora and father PJ, both 3 years old. The second egg in their nest shows pipping activity and is expected to hatch on Easter Sunday. The newly hatched chick weighs 2.1 oz. Humboldt penguin chicks hatch with grayish brown, downy feathers, which molt into completely gray feathers when they fledge. It will be early summer before any of the chicks emerge from the nesting burrows and venture outdoors into the public exhibit for visitors to enjoy. Over the last few weeks, three pairs of Humboldt penguins have been sitting on two eggs each in the burrows specially constructed for the birds in their new exhibit. At least two of the remaining four eggs are fertile. Staff plans to cand
