Birthday Parties and Easter Fun

Ambassador Days, Carnivores, Cheetahs, Community

This week was a fun and eventful weekend for the carnivores here at the park. On Friday, our two tiger girls, Riya and Kemala turned 7! We celebrated with the girls by giving them one of their favorite summer treats, blood popsicles. They even got some fun birthday decorations with some of their favorite meat snacks hidden inside.

On Saturday, our two ambassador cheetahs, Khayam and Mchumba celebrated their 7th birthday with tons of guests and their keepers. Our wonderful docents provided a cat friendly birthday cake (which they loved) and tons of fun paper mâché (all safe for the animals) and birthday decorations to play with. We shared the love with some of the other cheetahs, including KJ and Rhino.

On Sunday, we celebrated Easter with all our animals by providing Easter baskets, made by our docents, and giants Easter eggs filled with snacks. Check out some pictures of our animals enjoying their enrichment! And a special thank you to all our wonderful volunteers who created all these specials treats and enrichment.

Meet Dumai

Carnivores, Creature Feature

Say hello to Wildlife Safari’s newest Sumatran Tiger, Dumai. Dumai came to us in January from Point Defiance Zoo in Tacoma, Washington. He was born and raised at PDZ and stole many hearts there over the last six years. Dumai is such a great new addition to our team and we are very excited to have him.  He is such a loveable guy and very easy going.

He was brought to us as part of the Species Survival Plan (also known as the SSP). He was recommended as a mate for our two female Sumatran tigers, Riya and Kemala. What is the SSP? It is basically like match.com for endangered or vulnerable species. This programs has each individual’s genetics on file and pairs them with a match that will produce the most unique genetics. This prevents any in breeding or one male or female from producing all the offspring. This is helping save wild populations. The Sumatran tiger is one of the most endangered living species of tigers. They only live on the island of Sumatra and are facing many challenges. One of these challenges is small population size, in turn leading to in breeding. This leads to many other health concerns. Zoos can help save this species by having a backup genetic pool. By making sure our population is healthy and diverse, the goal is we can possibly AI females in the wild with our genetics in order to prevent more inbreeding from happening, which will help keep the wild population healthy. Come see Dumai and our two females in the cheetah drive through.

Snow Zone!

Carnivores, Cheetahs, Elephants, Ungulates


This past week, Wildlife Safari was transformed into a winter wonderland when the park experienced the most snow in recent history. Although the park had to close for the time, the animals sure had fun experiencing some snow and enjoying extra browse from fallen trees. Animals that are more sensitive to cold temperatures were not left out for the full day, only in short segments in order for keepers to clean inside holdings and for them to enjoy the snow. All animals in the park have access to heat lamps and covered shelter if needed. Even our smallest cheetah and dog duo got to pop outside for a few minutes to experience their first snowfall! The park is working hard to clear snow and any debris and getting ready to reopen the park!


Know Your Spots

Carnivores, Uncategorized

Whenever I am at a zoo I always hear kids and adults alike call animals by the wrong name. The most common mistake I hear is whenever they see a cheetah, leopard, or jaguar, people assume it is a cheetah. The hardest ones to tell apart are the leopard and jaguar because they have very similar spots and body build. Though in the wild it is easier because they live on different continents. These cats have many features and behaviors that differentiate them from each other, although, in the case of the cheetah and leopard, they live in the same place. In this post I have listed out key differences between these three beautiful big cats so you can educate those around you while visiting your favorite zoo.

 

Cheetah

  • Body: lean and lanky
  • Weight: 80-100 lbs
  • Speed: 70 mph
  • Hunt during the day and solitary
  • Life span: 8-10 years (in the wild)
  • Largest cat that purrs; can’s roar
  • Lives in Africa
  • Circular spots

Leopards

  • Body: more stalky than cheetah; less than jaguar
  • Weight: 66-176 lbs
  • Speed: 36 mph
  • Hunt at night and solitary
  • Life span: 12-17 years (in wild)
  • Roars; can’t purr
  • Lives in Africa
  •  Rosette spots

 

Jaguars

  • Most stalky of the 3
  • Good swimmer/enjoys the water
  • Life span: 12-15yeas (in wild)
  • Lives in South America; solitary
  • Weight: 100-250 lbs
  • Rosette spots with spots in them

 

Is it a brown bear or it is a grizzly?

Carnivores

To really answer this question, let’s start by looking back at some brown bear taxonomy (the branch of science concerned with classification, especially of organisms) history, shall we?

Bear taxonomy went through many revisions before scientists recached the conclusion of Ursus arctos.In the nineteenth and twentieth centuries, taxonomists frequently lumped and split brown/grizzly bears into many different species and subspecies. In 1918 the separation peaked with the publication of C. Hart Merriam’s “Review of the Grizzly and Big Brown Bears of North America.” Merriam proposed around 80 species and subspecies of North American brown bears existed. Merriam’s nuanced classifications of brown and grizzly bears were based on differences in skull morphology and dentition, which he examined in painstaking detail. Merriam classified on southeast Alaska’s Admiralty Island alone, there was 5 distinct subspecies and in the Katmai region, 2 distinct subspecies as well as other living in the Cook Inlet area and on the Kenai Peninsula. But most of the species or subspecies described by Merriam were later regarded as local variations or individual variants. As of the mid 1980’s as many as 9 extant or extinct subspecies of U.arctoswere recognized in North America.

Which brings us to the age old saying “All grizzly bears are brown bears but not all brown bears are grizzlies”. Now even with all the research done by Merriam this saying still has some backing to it. Now a days there are only 3 main subspecies of brown bears recognized by most of the scientific community, Kodiak brown bears, Alaskan Coastal brown bears and Grizzly brown bears. These bears are very similar but still have their differences to classify them as different subspecies. The 2 big determining differences are size and location. Each of the subspecies are geographically and genetically isolated from the other subspecies of brown bear.

Kodiak brown bears (Ursus arctos middendorffi) which main populations are only found on Kodiak Island in Alaska are the largest of the brown bear subspecies. Now these bears are not genetically different enough to be classified as their own species but are distinct enough that they can be classified as their own subspecies because they been isolated from mainland bears for over 12,000 years. Now these bears can get up to 1,500lbs and stand up to 10ft tall. Kodiak brown bears can get this big because they live on islands and they have access to a marine-driven food resource all year round with their favorite being salmon!IMG_9376

The next subspecies, very similar to Kodiak brown bears, are the Alaskan Coastal Brown Bears (Ursus arctos gyas). These bears are known as the ABC island bears  because their populations are only found on Admiralty, Baranof, and Chichagof island in southeast Alaska. Alaskan Coastal brown bears can reach large sizes as well, they can reach up to 1,200lbs and stand around 8 ½ to 9ft tall. Just like the Kodiak brown bears, Alaskan Coastal brown bears can reach this size because of their access to marine-driven food resources all year round with their favorite being salmon too! Alaskan Coastal brown bears are unique because they are the most genetically different compared to all other brown bears. Alaskan Coastal brown bears actually share more genetic information with polar bears than other brown bears. This could be due to interbreeding with a small isolated number of polar bears during the last ice age. As more recently, scientists have found more Alaskan Coastal brown bears with polar bear DNA in the northern parts of Alaska suggesting that there has been more interbreeding recently and possibility creating a new bear species, currently known as a “Prizzie”!

The final subspecies is the most common of the three and the reason for the main question of this post, Grizzly brown bears (Ursus arctos horribillis). Grizzlies are considered the smallest of the 3 brown bears subspecies. On average, grizzly brown bears only reach up to 900lbs and 7ft tall. Grizzly brown bears are much smaller because they are inland bears with there main populations found in southwestern Canada and the lower 48 states, they do not have easy access to a marine-driven, high calorie food resource. So Grizzly brownbears must work a little harder for their food, so they don’t build up as much fat as compared to the other 2 subspecies of brown bear. Grizzly brown bears are also known for that distinct hump on their backs. That hump is pure muscles from their shoulders as is usually used as a key morphological identifier for Grizzly brown bears. Grizzly brown bears are also found to be a bit more reactive to humans being around in the distance. This doesn’t not mean they are more aggressive than the other brown bear subspecies, but it is a behavior picked up because Grizzly brown bears are in more human populated areas compare to the other subspecies who live on mostly unpopulated islands. All three subspecies have about the same temperament.

Now that you have the facts, what do you think? Is it a brown bear or is it a grizzly? Do you agree with the statement of “All grizzly bears are brown bears but not all brown bears are grizzlies?” or do you think more research needs to be done? Let us know by leaving a comment

A Day in The Life of a Zookeeper

Behind the Scenes, Carnivores, Cheetahs

No matter what group of animals a zookeeper works with, their daily tasks will basically be the same. It is a zookeeper’s job to make sure that the animals under their care are both physically and mentally healthy, which makes cleaning up after them an important daily duty. In fact, a large amount of a zookeeper’s day is spent cleaning! From hosing and scrubbing an animal’s enclosure, to washing dishes, and even cleaning toys and work areas, zookeepers do a lot of cleaning up! It may not be fun, but it is absolutely essential to the proper care and upkeep of the zoo’s animals.

Another important daily task that all zookeepers must do is prepare food for their
animals. Since most animals aren’t like humans in that there is a large range of things that we are able to eat, making diets for zoo animals can be relatively time consuming.

IMG_9368

Our 6 year old lioness, Mati

In order to keep their animals at a healthy weight and make sure that they are getting all of the nutrients that they need to remain healthy, many diets have to be carefully planned out.

For example, when wild lions take down their prey, they will gorge themselves on it and will typically end up fasting for a few days. They won’t be finding and catching prey every single day, so the fasting is kind of forced on them due to nature. However, this kind of diet is actually good for them as long as they are able to eat often enough that they aren’t starving. Fasting gives the lion’s body a chance to detox – or get rid of any harmful substances that may have found their way into the lion’s body.

Many zoos that house lions have them on a diet which is close to that of wild lions. At Wildlife Safari, our lions are fasted once a week. On their fast day, they still receive a diet, however it is mostly bone and barely any actual meat. The rest of the week, they are on diets which were developed based on the health and weight of each lion. This works very well for our lions, but other zoos may have a different diet plan for their lions. This doesn’t make them wrong, as zookeepers often have to adjust dietary details for their animals based on what they need for their health and weight.

When zookeepers are not cleaning, preparing diets, or feeding their animals, they are often educating the public! One of the greatest tools that a zookeeper has in their arsenal is their voice. By educating others, zookeepers are able to touch the hearts of people who often already care about animals, but end up caring even more after learning so much about them. This may result in individuals making decisions in their lives that can be beneficial to animals and the earth, such as recycling or donating to an organization that helps to save endangered species.

Between all of these tasks, nearly all zookeepers implement some form of training into
their daily routine. Training animals in a zoo can be extremely important. Not only is it a mental challenge for the animal being trained, but it can also make things such as voluntary blood draws possible! It is always best to try and do medical procedures on an animal while it is willing and awake rather than having to sedate them. It is much less stressful for them, and the animal will see it as a more positive experience since they always get rewarded for doing a good job.

So even though there is a lot of hard, and often challenging, work involved in a zookeeper’s daily duties, it is the best job in the world. Just being able to see the animals that they care for almost every day is enough to make zookeeping fun for those who are passionate about it.

Learning from History: How We Can Help Tigers Today

Carnivores, Uncategorized

Wildlife Safari is home to two 5-year-old Sumatran tiger sisters, Riya and Kemala. Sumatran tigers are currently one of the most endangered tiger subspecies in the world.  There are less than 400 Sumatran tigers left in their native habitat, the island of Sumatra in Indonesia.  Two other islands in Indonesia were also previously home to tigers, the Javan and the Balinese, but those two subspecies are now extinct.

IMG_2063

Before the 1900s, there were nine subspecies of tigers: the Bengal, Indochinese, Malayan, South China, Javan, Siberian, Balinese, Sumatran, Malayan, and the Caspian.  There are now 6, as the Caspian tiger has gone extinct along with the Javan and the Balinese subspecies. These three subspecies have been driven to extinction in the last 100 years, showing how rapidly the populations of tigers can decline. Hunting, habitat fragmentation, loss of habitat, and loss of prey are the main causes of extinction among tigers.

In Sumatra, the main struggles the native tigers face are habitat loss and fragmentation due to palm oil production, and poaching by hunters who value them for their furs and other parts of their bodies.  Unfortunately, there is a high demand in Chinese medicine where their eyes, bones, teeth, and whiskers are seen as having healing properties.  Laws and regulations are in place for poaching, but unfortunately, poachers are still able to hunt endangered species regardless of them.  Palm oil is used in a wide variety of different products such as makeup, food, soaps, detergents, and biofuel.  The majority of palm oil is harvested in Indonesia and Malaysia, and much of it is not harvested using sustainable sources.  As a result, the habitats of the Sumatran and Malaysian tigers are being broken up and are shrinking down as palm oil production increases.

IMG_1825

Fortunately, tigers have many organizations and individuals willing to aid them in their continued survival.  There is a lot people can do to help out tiger conservation! Supporting conservation efforts through donations, “adopting” a tiger, or even volunteering your time will help those that are trying to directly impact the conservation of tigers.  Learning more about how to purchase products that are made with sustainable sources of palm oil (or that don’t use palm oil at all) can help reduce the impact that palm oil plantations are having on tiger habitats in Southeast Asia.  Lastly, educating others about the status of tiger subspecies, conservation efforts, and how they can assist will help spread the word and hopefully inspire others to get involved!

Mountain Lions in Oregon: The Biggest Predator You Never See

Carnivores, Creature Feature, Uncategorized

Just how likely are you to run into a fierce predator on your hike through a state park or national forest? Most of us assume it’s unlikely. The image that comes to mind is of rainforests or savannas housing tigers, lions and cheetahs. Those are half a world away from us, but that doesn’t mean they aren’t there.

mountain lion6

With a distribution over two continents and the ability to adapt to a variety of climates, the mountain lion could be considered king of the American jungle. This species is the most widely distributed mammal in the Americas, with 30 subspecies and a bundle of common names including the cougar, puma, and panther. Mountain lions are on the bigger end of the smaller cats, weighing around 120-190 lbs. Their tan and reddish fur provide good cover in the trees and rocky mountains of both North and South America, while their classic felid jaws and claws aid in their ambush method of hunting of which there is a 70% success rate. Like most other cat species mountain lions are solitary animals, with the exception of mating and females with cubs.

Worldwide mountain lions are a species of least concern by the IUCN Redlist with an overall estimation of 30,000 individuals, but their numbers are starting to decrease. In fact, they aren’t found in the Eastern United States, after being hunted out in the last 200 years. The Pacific Northwest has a good portion of the United States’ mountain lions, with numbers around a few thousand in each state. They don’t appear to be limited by human activity, but rather by the amount of prey species available. In Oregon, the mountain lion population is estimated at 6,400 as of April 2017.

Each state monitors their populations in slightly different ways, and here the mountain lions fall under the Oregon Department of Fish and Wildlife (ODFW). Their goal is to keep the population above the 1994 level of 3,000 individuals. They also monitor the number of conflict animals in the state, or animals that cause damage to people’s property or person. These animals will be removed if necessary, and if the number of conflicts is too high or the prey species are suffering losses from too many mountain lions ODFW is prepared to adjust the population. In other words they want a stable population of mountain lions, not too many or too few.

mountain lion4

In addition to monitoring the population status ODFW sets hunting regulations for the state. Mountain lions are listed as a big game species in Oregon, and are hunted using the same tag system as other big game. Hunters can take both males and females during the mountain lion season, but mothers with cubs are off limits. In the past it was legal to use hunting hounds to tree a lion, or track and corner a mountain lion in a tree. However, using hounds for hunting a mountain lion is illegal for sport hunters, which has lowered the success rates of mountain lion hunting in the state. There is some speculation that this could have caused an increase in the population, but as of now there is no research to support the theory.

mountain lion9

That’s not to say there is a lack of mountain lion research in Oregon, not by a long shot. There have been over a dozen research publications affiliated with ODFW in the last decade alone. They include subjects like establishing more accurate mountain lion densities and population growth rates, effects of lethal control, kill rates and prey selection, and the effects on population dynamics of elk (one of their prey species). In southwestern Oregon there was a long-term study from 1992-2003 that radio collared and captured mountain lions and gathered data on home ranges, prey interactions, reproduction, and dispersal. All of these pieces of research are important to the whole picture of the mountain lion-how it lives, factors that could affect its survival, and how to best live alongside one of our biggest top predators.

So the next time you pick up your hiking boots, remember and respect the fact that you may not be as alone as you thought out there. Keep an eye out for tracks, because Oregon’s mountain lions can be seen if you know how to look.

It’s International Cheetah Day!

Carnivores, Cheetahs, Uncategorized

December 4th is a day set aside for the fastest land animal on Earth: the cheetah!  Wildlife Safari is home to 20 cheetahs, both cubs and adults!  Our youngest little ones are just over 15 weeks old and are growing larger and stronger every day.  Cheetah cubs will stay with their mothers for the first 1.5 – 2 years of their life.  During this time the mother feeds them, protects them, and teaches them how to fend for themselves.  Our four cubs, Amani, Roudy, Zigzag, and Corey, are lucky to have a mom who takes care of them very well.

The cheetah has adapted to a quick lifestyle; a 70mph lifestyle to be exact.  The cheetah’s anatomy is specifically built for speed.  They have slender bodies that allow them to be agile and accelerate from 0 – 60mph in less than 3 seconds! Other adaptations that allow this are their flexible spine, semi retractible claws, enlarged nasal cavities and lungs.

Many people mistake a leopard or jaguar for a cheetah.  However, the cheetah has a distinguishable face by their tear marks that run down their face from their eyes.  These two black stripes are the only stripes on a cheetah’s body and help refract the sunlight out of their eyes, allowing them to hunt during the morning and evening hours.  Another way to tell a cheetah apart from other cats are by their spots.  A cheetah has 2 – 3 thousand solid black spots on their bodies. These spots are to help camouflage them into their environment and to help cool them off after a run.
