Posted by: Peter S. Miller, Zookeeper “Is it safe to come out yet? Not yet, maybe tomorrow.” These are the thoughts that might arise in the brain of a Louisiana pine snake hatchling. It is a chance decision that could mean your life or death in the wild. Such is the beginning of life for an endangered Louisiana pine snake. Next thoughts: hide or eat. When your serpentine undulations would signal a nearby predator that a tasty meal has just emerged from a clutch of eggs under the soil, stealth is critical…but so is breakfast! As the old adage goes, “eat or be eaten.” The Louisiana pine snake, Pituophis ruthveni , is a species under threat from habitat alteration of its native longleaf pine forest in the southeastern United States. This species has just increased its numbers on planet Earth by two, thanks to hatchlings that emerged late this summer at Woodland Park Zoo’s Day Exhibit. This accomplishment might not sound like much, but when your species is rare in the wild and

Posted by: Carolyn Sellar, Zookeeper In February we blogged about the departure of gorilla Naku from Woodland Park Zoo to start a new family in Milwaukee. Here’s an update on how she’s transitioning! The entertaining and rambunctious Naku, a 10-year-old female western lowland gorilla , went to Milwaukee County Zoo at the end of June to begin a new family with Cassius, Milwaukee’s 25-year-old resident male. She had a very smooth flight there and after her standard quarantine at the zoo, she was transferred to their gorilla unit where introductions are now in progress. The introductions have been going very well and Naku is now part of a group with both Cassius (shown above) and another female named Femelle. She spends all day with both the other gorillas, and for now spends the night just with Femelle, but soon they will all be spending the night together. In fact, it is often difficult to separate Naku from Cassius! She must be smitten! If things progress the way they ha

Posted by: Rebecca Whitham, Communications Exciting news—we’ve made the very first sightings of our Matschie’s tree kangaroo joey! At six months old, the joey is just now beginning to emerge from its mother’s pouch. First the keepers spied only the joey’s ear poking out of the pouch, but within a few days, its whole face emerged. Joey’s face emerges. Photo by Wendy Gardner/Woodland Park Zoo. Born the size of a lima bean in December 2010, the joey has been developing unseen inside its mother’s pouch where it gets nourishment and protection. Tree ‘roo mother, four-year-old Elanna, has been cleaning the joey and providing excellent care. The two are living adjacent to father Huen in a quiet outdoor exhibit behind the scenes at the zoo where keepers can closely monitor the progress of mom and joey. Mother Elanna feeds while joey remains protected in pouch. Photo by Wendy Gardner/Woodland Park Zoo. This rare birth, part of the cooperative breeding Species Survival Plan program fo

Posted by: Rebecca Whitham and Gigi Allianic, Communications Over the past two years, we have all watched snow leopard cubs Gobi and Batu grow and explore—from their precious first weeks , to their big debut , their first birthday and their participation in a smelly study to help track wild snow leopards. But now we’re preparing to say goodbye to Gobi, our male juvenile who is 2 years old and ready to move on to a new home at Rolling Hills Wildlife Adventure in Salina, Kansas. Gobi—who got his name from more than 35,000 votes cast by zoo fans —has been recommended to move as part of a cooperative breeding management program known as the Snow Leopard Species Survival Plan (SSP). SSPs work to ensure genetic diversity and healthy populations. The SSP does not have immediate plans to breed Gobi, but this is an appropriate age for him to make his departure following the natural course of how snow leopards live in the wild. Snow leopards are essentially solitary animals and it is

Posted by: Carolyn Austin Sellar, Zookeeper This is the third entry in our new Animal Spotlight series... For as long as many of you may remember, Pete the male silverback gorilla, has headed up our Gorilla Group 1 . This year Pete turned 43 and is the oldest male gorilla at Woodland Park Zoo. Despite having some of the typical complaints of old age, including arthritis and yes, even developing a bald spot (I know hair loss for a male can be embarrassing), Pete is in relatively good health considering his age. The average life span for gorillas in captivity is late 30s to early 40s with females living longer than males. In the wild, it is roughly 30-35 years. The longest living captive gorilla on record was 55 (a female). Although Pete is well into his golden years, he is still going strong. He has always been, and continues to be, the gentleman gorilla and always says “Thank you, tastes good!” by way of his grunts of contentment while he eats. When Pete first came to Woodland Park Zo

Posted by: Carolyn Sellar, Zookeeper Introducing a new series to the blog... Who is: a rowdy 10-year-old gorilla ; with ears that stick out; a female in silverback Pete’s troop ; who is leaving soon to start a new family? Our girl Naku (aka Nakunator or Naki, as her keepers sometimes call her)! This spring Naku will fly to Milwaukee, the land of cheese, breweries, and Laverne and Shirley. There she’ll be introduced to some new gorillas in hopes of starting a brand new family, including handsome resident male gorilla, Cassius, and female Shalia, who is also arriving new to Milwaukee, coming from Toronto. Naku’s 10th birthday was a very significant gorilla birthday. Her first double-digit birthday is a milestone that means she is mature enough physically and emotionally to become part of the cooperative breeding effort known as the Gorillas Species Survival Plan . This timing corresponds to the age at which wild gorillas begin to venture off to look for a new group to belong to, or begin

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 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: 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: 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

Posted by: Rebecca Whitham, Communications Recently, jaguars Nayla and Junior had their first chance to spend time together in their outdoor exhibit, the award-winning Jaguar Cove. The two are being introduced for potential breeding as part of a Species Survival Plan effort to maintain a healthy population of this endangered species. But first, these usually solitary animals have to get to know each other... (Tip: Turn up the volume to hear an explanation of the jaguar behaviors you are seeing.)

Posted by: Ryan Hawk, Photographer A few weeks ago, on a rainy, rainy day, zookeeper Kimberly Cooper and I hopped in the zoo’s Prius and traveled to the off-road back areas of Fort Lewis to release the last few of this year’s batch of about 450 Oregon spotted frogs . In the first year of the recovery program at Woodland Park Zoo, the endangered frogs were raised on zoo grounds to be given a head start in the wild. It’s one of several species recovery programs the zoo participates in locally. Zookeepers like Kimberly raise the frogs from egg to adult in order to increase their odds of survival in the wild. The work takes place behind the scenes in a quiet corner of the zoo’s 92 acres . Watch the release in this short video. Woodland Park Zoo participates in the recovery program in collaboration with partners including Northwest Trek , Oregon Zoo , Cedar Creek Correctional Facility, and the Washington Department of Fish and Wildlife . And each of these groups were represented as we re

Posted by: Rebecca Whitham, Communications For the first time in three years, Woodland Park Zoo is once again home to the Matschie’s tree kangaroo ! This endangered species is endemic to Papua New Guinea and is known for its bear-like head, bushy tail and marsupial’s pouch. Huen, an eight-year-old male, is a little shy when it comes to the camera, but we snapped this photo of him while he was perched up in a tree. Huen arrived from Singapore Zoo in March and can now be found living in the Day Exhibit. As one of the newest conservation ambassadors at the zoo, Huen represents the inspiring work of the Tree Kangaroo Conservation Program , founded and based here at Woodland Park Zoo. You might remember the big news we shared earlier this year when Woodland Park Zoo’s Tree Kangaroo Conservation Program celebrated a milestone with the passage of Papua New Guinea’s first ever national Conservation Area , preserving 187,800 acres of forest habitat for the endangered Matschie’s tree kangaroo an

Posted by: Walter Dupree, Animal Collections Manager On June 23, Woodland Park Zoo became home to another significant addition…a bouncing eleven-month-old female giraffe named Tufani. She came to us from Dickerson Park Zoo in Springfield, Missouri. For those that remember, this is the same zoo that sent us Olivia, our other female giraffe . In fact, Tufani and Olivia are half sisters. And no, they don’t seem to recognize each other, but with giraffe, you never know. Like Olivia, Tufani is a Rothschild’s giraffe also known as Baringo or Lado giraffe. Although she is not a Reticulated giraffe like our males, the Association of Zoos & Aquariums’ Species Survival Plan manages them as one sub species so we have future breeding recommendations already. But don’t expect to see any infant giraffe running on the savanna anytime soon as our girls are still a bit young. If you’ve never seen a giraffe shipment before, it’s an interesting undertaking. I bet a few of you are wondering how we ge

Posted by: WPZ Field Conservation staff Southeast Asia is home to the world’s smallest bear species, the Malayan sun bear . These little bears face big threats throughout their range, especially from forest destruction, illegal hunting, and the capturing of small cubs for pets. Luckily this unique bear has a champion and protector in Siew Te Wong , a Malaysian researcher and Ph.D. candidate at the University of Montana. Woodland Park Zoo has helped support Wong and his field work in Sabah, Borneo for several years. As one of the very few people studying the sun bear, Wong has uncovered many fascinating aspects of sun bear ecology. Sadly, though, his research also brought him first-hand experience of the inhumane treatment of sun bears kept as pets. Wong’s deep concern for these animals has inspired a new and ambitious project: the creation of the Bornean Sun Bear Conservation Center , a partnership between the Sabah Wildlife Department, the Sabah Forestry Department and nonprofit LEAP
