Change

by

I don’t think a day goes by at the sanctuary right now without significant change of some sort. Learning behaviors and personalities from new chimpanzee friends, seeing new behaviors with long-time chimpanzee friends, new areas for chimpanzees and humans to access and former ones temporarily closed off, new procedures and protocols, new ideas, new volunteers and interns for autumn, scheduling changes, and even, well, things like one minute someone has their ear and the next, they don’t. Change, expected and unexpected, is always occurring, just on a more obvious level these days. And now, on this last official day of summer in the Northern Hemisphere, we seem to have moved straight ahead into autumn. (Though in my book, I’d be thrilled with nine months of autumn).

I think as humans, or at least as this human, we often expect, or at least prefer some things to remain the same, predictable. But even though we celebrate things such as the transitions of one season into the next, if we’ve been paying any attention at all we’ve seen all the tiny every day things that lead us ahead into the next phase of life. With breaths of fresh air, new inspiration, new beauty to appreciate, new beings to love.

The chimpanzees last day of summer was a cool, rainy one here. It worked out well enough as they were all busy supervising the many humans working hard to expand their outdoor habitats which will be bringing new experiences to them in the days to come. Along with hopeful new friends and family when we soon begin introductions. Always changing, always growing.

The evening air is filled with the slowing song of crickets and frogs while the dark of night is increasingly alive with geese calling as they pass overhead on their way south. The chimps are all tucked into their blanket nests for the night, I suspect milling over their own thoughts and anticipation of change. May your hearts be as full from the beauty and bounty of summer as you’ve helped the chimpanzees’ to be, as you listen to the last sighs of summer rustle the changing leaves of autumn.

I had these photos of beautiful Foxie saved to share with you, which just happen to be pre-ear biting incident.  She’s still just as beautiful. 🙂

Honey B’s Style

by

As highlighted in a recent post, Honey B is already known for her intelligence, energy and creativity. Not only is she an engineer and a philanthropist, but she is also a fashion enthusiast.

Yesterday, she decided that the cloth headbands we provide as enrichment are better suited as waistbands. Interestingly, she isn’t the first chimp to have this innovative idea! As caregiver Kelsi showed us last month, Annie has been wearing headbands around her waist for years.

It would be tempting to suspect that Honey B learned the behavior from Annie, which would be great evidence of cultural transmission between groups of chimpanzees. In the wild, chimpanzee communities across Africa have cultural traditions (i.e., their own ways of doing things) that spread among individuals via social learning. Chimpanzee cultures are rich and fascinating, but may be disappearing. This year, scientists published a paper about the negative effects that human activity may have on the cultural diversity of wild chimpanzees. As chimpanzee numbers dwindle and we degrade and fragment their forested habitats, their capacity for culture catastrophically decreases.

Although the process of cultural transmission certainly exists among groups of captive chimpanzees, it has been difficult to document and is seldom reported. In the case of Honey B and the waistband, it seems unlikely that she learned it from Annie. Annie only wears the improvised belt for a few days or weeks and then ignores them for the rest of the year, and she had already stopped wearing this summer’s edition before Honey B and her friends arrived from Wildlife Waystation last month. It is possible that one of the many videos we showed to the new trio features a scene of Annie sporting the headband-waistband look, but it’s more likely that they both just have similar taste in enrichment and utilize what we give them in novel ways.

With that being said, it will be interesting to see if any behaviors do cross over from one group to the next! Chimpanzees are brilliant and creative, and never stop surprising us.

 

Summer’s End Begins

by

The rain today did not feel like a passing summer shower. It felt like summer’s end.

Besides the rain, many smaller changes have become evident this weekend. As the temperature dipped, the mountains shrouded themselves in chilly fog and gray drizzle. The larches are abandoning their greenish hue in favor of warmer tones. The bucks that inhabit the woods around the sanctuary are showing off their new antlers, while this spring’s fawns are losing their spots and grow more independent by the day. The tourists in nearby Roslyn are sporting flannels and hoodies, not sunglasses and flip flops (and our staff and volunteers had to say a sad goodbye to this year’s edition of the Roslyn Farmer’s Market). In neighboring Ellensburg, new students are flocking to campus to begin classes next week; a handful of them will compose our next cohort of interns starting at the end of this month. The air itself seems to call for coffeehouse folk music and pumpkin spice everything. Autumn has made its first appearance of its three-month residency.

Meanwhile, the chimps are embracing the cooler surroundings in their own way.

Jamie spent this morning huddled under a makeshift tent of blankets, taking in the crisp morning air and watching the caregivers go about their morning rounds. She even snoozed for a bit before breakfast (as did Annie, in the background).

Over in the new wing, things went similarly. Lately, the new three have been chilling out in the new archway tunnel almost constantly. However, today’s weather made the uncovered chute less appealing and the trio spent more time grooming and nesting in their sheltered indoor spaces. From her secluded corner in one of the bedrooms, Mave made sure to keep looking out the window at the surrounding pastures, passing rail cars and two-lane highway far below.

Because of the drizzle and dew, we only scattered a small portion of their lunch on Young’s Hill. Even so, the seven long-term residents made the best of the conditions and found all of the carrots and walnuts that Level II volunteer Dusty placed among the tall grass and wooden structures. Of all the chimpanzees, Annie seemed to enjoy foraging in the damp prairie grass, always watching her surroundings for potential competitors and new opportunities to obtain more food.

Today’s only drama was centered around corn. Erin and Miranda, two of our dedicated Level III volunteers, served breakfast and lunch, respectively. All went smoothly until Jamie decided to get upset every time one of the lower-ranking females received an ear of corn-on-the-cob. Either she was being possessive (likely) or she’s terrified of things on cobs (slightly less likely). She kept her eyes on everyone else while she munched on her own corn, as well as poor Foxie’s.

Annie, Foxie, and Missy all processed their remaining corn and potatoes with trepidation, frequently pausing to monitor Jamie’s expression.

Missy even had a swollen eye this morning. It was not a grievous wound by any means, but served as a potential artifact of recent conflict within their social group (Note: Missy didn’t seem to care and even made J.B. playfully chase her around the Hill in the rain).

Only Negra and Burrito were left out of the corn fiasco. Negra opted to sift through her chow bags from the safety of her fleece blankets, while Burrito spent more time gazing over at the adjacent tunnel and neighboring chimps.

 

Great Expectations

by

We caregivers have been incredibly busy lately, but we make a point to read comments on our social media content and we attempt to respond appropriately whenever possible. Lately, most of our followers, donors and volunteers have been overwhelmingly focused on one topic in particular: social integrations. More specifically, everybody wants to know about our plan for introducing the three new individuals (Honey B., Willy B. and Mave) to our existing social group of seven resident chimpanzees. Diana described the situation eloquently in her recent post, which is a “must-read” for anyone trying to follow the action here at the sanctuary.

Willy B. and Mave listen to the other group of chimpanzees in the adjacent Playroom.

As stated previously by the other staff, the incoming trio are about to clear their four-week quarantine period and we are formulating a loose plan to begin the introduction process. All members of our care staff are experienced in chimpanzee care and management, but we have never conducted a merger of two social groups in this unique facility or with these individual chimpanzees. Therefore, it is impossible to write a detailed, step-by-step description of our introduction plan. We are committed to remaining flexible and open-minded from start to finish, and will make whatever changes are needed to ensure the safety and well-being of all chimpanzees throughout the process. As with the outdoor tunnel, The chimpanzees will let us know how they feel about each step and we will adjust our plan to reflect their choices. At this point in time, all we can say is that we have scoured the written literature on chimpanzee social integrations, consulted with experienced personnel from other facilities and organizations, and aggregated our own observations in order to make the best decisions for these individual chimps.

The existing scientific reports of first meetings between unfamiliar chimpanzees have somewhat helped us to set our expectations. Chimpanzee social behavior is by far the most thoroughly studied of all wild primates, and there are substantial bodies of work on their behavior in captivity as well. What we see around the sanctuary is often paralleled by what scientists have seen at other locations and in other populations of chimpanzees. To illustrate this point, let’s consider Burrito’s behavioral changes since the new three entered his world, both audibly and visibly.

Burrito Chimpanzee stomps around the Playroom.

In general, Burrito has been more alert and agitated than usual. He has conducted more forays onto Young’s Hill to monitor the section of fence closest to the new expansion, spends more time gazing towards the neighboring enclosures, and creates more noise by drumming and throwing objects around the Chimp House. He has been uncharacteristically late for some meals and even skipped a couple courses entirely. During these absences, we hear him getting rowdy by the Playroom windows, usually within sight of the three new arrivals who can watch the spectacle from the safety of their outdoor tunnel. Once his displays and hoots reach their inevitable crescendo, he leaps towards the window and stares intently, apparently waiting for a response. When he does show up tardy for meals, he has been swaggering up to the Greenhouse deck and then charging through the females, scattering them and causing a ruckus. This is an edgier version of Bubba than we have seen previously.

Burrito looks out of the Playroom window after completing a display.

This change in Burrito’s behavior is evidence of what some primatologists have called the neighbor effect. In their 1996 study of chimpanzees housed at a large research facility, Dr. Kate Baker and Dr. Filippo Aureli observed captive chimpanzees to determine whether noise from neighboring groups had an observable effect on each individual’s behavior. To summarize their findings, chimpanzees tended to perform more pant-hoots, displays and outright physical aggression when neighboring groups did the same. Aggression outside of social groups was related to aggression within groups. For captive chimpanzees, rowdiness and instability are apparently contagious. Right now, we are witnessing a similar pattern of behavior here at CSNW.

Willy B. watches Burrito from across the yard.

Other aspects of captive chimpanzee behavior have been studied at facilities around the globe. For example, recent studies have investigated how chimpanzee behavior varies in relation to temporary space restrictions, permanent relocations, different enclosure types, and atypical rearing histories. One study even asked whether chimps find music enriching (results: “meh”). Most of these papers were produced from data collected at no more than a few facilities, and many publications are mere case studies of single groups of chimpanzees. Each facility is unique and groups of chimpanzees can vary greatly depending on social structure, cultural variation, and context. Thus, even though there is a good deal of information out there, it requires a good deal of sifting and speculating to apply it to our chimpanzee residents here at the sanctuary.

Missy Chimpanzee monitors the neighboring chimps.

In a couple of situations, we have invited graduate students to conduct noninvasive applied welfare studies at the sanctuary. We are definitely not a research facility and do not profit from scientific investigations, but collecting systematic observations can generate information that can then be used to optimize our care of the chimpanzee residents. Central Washington University (CWU) is located in nearby Ellensburg and contains the nation’s only Graduate Program in Primate Behavior, so a handful of committed CWU students have helped us to answer key questions about the Cle Elum Seven. Most recently, a collaborative team led by Jake Funkhauser published his analysis of the sanctuary’s chimpanzee social network and dominance hierarchy. This report, although only based on a summer’s worth of observations, produced insight that has proved valuable as we prepare to add three new individuals into the mix.

Foxie Chimpanzee expressed her arousal and uncertainty during one of Burrito’s displays.

Additionally, we recently hosted Chimp Haven’s Director of Behavior and Research, Amy Fultz, who observed the chimps and inspected the facility. Amy has coordinated countless introductions between unfamiliar chimpanzees and numerous mergers of large social groups, thereby developing an immense body of knowledge and wisdom that she was generous enough to share with our team. Even as she gave us some useful tips and relayed some incredible stories, she also emphasized a few points that we already knew: that each chimpanzee is a unique individual, that each facility offers its own advantages and challenges, and that any introduction between two groups can take a surprising turn at any moment. It’s best to have a plan, of course, but the plan will inevitably change as we acquire new information about the chimps and their preferences.

Burrito Chimpanzee watches his neighbors through the caging of the Greenhouse.

Even with a wealth of available data and input from various sources, we know that this is unfamiliar territory for these ten chimpanzees and is a big step for our team as well. Ultimately, we will put these two groups together in our own way, the CSNW Way, which will be whichever way works best at that moment in time. For now, our staff is continuing to observe how the chimpanzees react to each small change in their environment and we will continue to share those moments with you whenever possible. We certainly appreciate all of your interest and support as we help the new three to acclimate to their new home, new lifestyle, and new neighbors, who will hopefully become their seven new friends. Shortly, we hope to have some updates for you all!

Won’t You Be My Neighbor?

by

It’s been a few weeks since Honey B, Willy B and Mave arrived from Wildlife Waystation, but it’s only been a few days since the Cle Elum Seven got their first glimpse of their chimpanzee neighbors.

The new arrivals get to access the outdoor tunnel (left) that will soon connect to the Young’s Hill enclosure.

As a staff, we’ve already noticed and discussed interesting patterns of behavior between the two groups. For example, Jody and Willy B have been spending considerable time staring at each other through the window. The three new arrivals have remained relatively composed and seem to be calmly sizing up their new acquaintances, while the seven original residents seem to be more excited. There was a huge mess by the windows in the Playroom this morning, indicating that the chimpanzees spent a lot of time looking outside at the adjacent tunnel.

The Playroom was trashed this morning.

Today was a bit unusual because we needed to briefly close off the outdoor tunnel and Young’s Hill for two separate maintenance projects. This meant that the groups were temporarily unable to see each other. Instead, Willy B. spent some time in front of the Howdy Door and made some noise to advertise his presence. On the Playroom side, Burrito and the others put on a concert of displays, screams and hoots.

For the seven original residents, checking in on the new cohort of chimps has taken up a lot of their time and effort, but has not completely derailed their usual activities. They enjoyed a lunch forage on Young’s Hill once the maintenance was complete, and Missy dominated the field by gathering up all the celery and bringing it into the Greenhouse.

Also, naps happened.

Now that the initial shock of seeing unfamiliar chimps has passed, the Cle Elum Seven seem to be monitoring their neighbors just as they keep tabs on the surrounding pastures, the volunteers, the tomato garden, and the refrigerator. The caveat is that these three new additions to the environment are also chimps, which means they are fully capable of responding right back.

Willy B + Jody

First, the photos that go along with the story in today’s blog are not going to win any awards. But the story is good, so I hope you’ll forgive my quick cell phone pics.

Second, if you are new to the sanctuary and the photos make you wonder why the chimps are in cages, please read this blog post that answers that very question!

Speaking of questions, I know there are SO MANY questions about how we are going to go about doing the introductions between the seven and the three. We still have a lot of questions ourselves that we have been mulling over. It’s daunting and scary and incredibly exciting all at the same time.

We’ve talked to a few different people who each have experience with hundreds (hundreds!) of introductions of chimpanzees, and each of them has a different general system they use and a philosophy behind it. On Tuesday, one of these very knowledgeable people, Amy Fultz from Chimp Haven, came out in person to talk to us about introductions. It worked out perfectly that she was here when the groups got the first good look at each other.

We are taking in all of this information and combining it with the data that Jake Funkouser recorded and analyzed of the social networks of the seven chimpanzees, and combining that with what we are observing of the new three and their interactions with the seven at a distance.

We also will let the chimpanzees dictate the process once we start. All that is to explain that we cannot share with you the step by step details before they happen because it’s not that kind of process and we are not there yet. We do plan to share details with you after the fact, though!

So, that brings me to today’s story about a connection/attraction between Willy B and Jody that is continuing to develop. It actually started before the three arrived at Chimpanzee Sanctuary Northwest. When J.B. and I were at Wildlife Waystation, we showed some videos of Jody to Willy B on my cell phone, and he immediately moved in to get a closer look,  paying more attention to the Jody videos than videos of any of the other chimpanzees.

Now they get to see each other in person every day, and Willy B continues to show an interest in Jody. And now we can say that the interest is mutual.

This morning, Jody made a special foray onto the hill and stood up just to get a glimpse of Willy B who was at the end of the chute:

Willy B returned the glance:

When Jody was heading back into the greenhouse, Willy B climbed to the highest spot in the new chute to have the best view:

Jody noticed his new position, and climbed up high on the caging in the greenhouse and made a low moan vocalization. Jody is famous for her various low-moans, most of them associated with food, and all of them indicating that she is happy.

With Jody’s cute hand wave/reaching out that J.B. included in the video yesterday and today’s friendly overtures to Willy B, our predictions about Jody being inviting towards the newcomers seems spot-on, unlike our inaccurate predictions of how Burrito would react to the sight of unfamiliar chimpanzee people.

Burrito, by the way, continues to be obsessed with the new three and spends most his day hanging out by the windows just waiting for them to appear.

Can you imagine how strange and exciting it must be to see new chimpanzee strangers for the first time after over a dozen years?!

A Tale of Two Pineapples

by

“A day wasted on others is not wasted on one’s self.” – Charles Dickens

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Volunteers Miranda and Elizabeth prepared breakfast this morning, with the centerpiece being a pineapple-strawberry-protein smoothie. The chimps ate their raw fruit and then drank every last drop of the bright pink smoothie. Of course, we couldn’t just throw the prickly pineapple tops into the Vitamix and we didn’t want to toss them in the compost bucket, either. Because the weather was so pleasant this morning, we ended up hiding the pineapple tops out on Young’s Hill at lunch, along with a forage spread of beets, carrots and potatoes. The chimps gathered themselves (and their dolls) and headed out to forage with gusto.

Of all the chimps, Jody is known for her expertise as a forager. We predicted that she would find at least one of the hidden treasures among the grass.

Surprisingly, Annie was the first to find a pineapple (the one that had been placed on a structure in the middle of the Hill). She triumphantly carried it back down the slope to the Greenhouse.

Negra found the second one since it was hidden in her favorite spot (a straw-lined cabin ear the bottom of the slope). She also carted her pineapple and vegetables back to the shade and shelter of the Greenhouse.

Annie’s pineapple wasn’t hers for very long before Jody casually took it from her. Annie didn’t seem to mind, though.

Jody reclined on the lower deck and relished every spiny leaf of the pineapple top. She held it lovingly and slowly picked it apart.

Neggie was a bit more industrious. Her mechanical breakdown of the pineapple top was quick and purposeful. She ripped off each spine and chewed it to a pulp before spitting it on the deck below. She soon had a pile of peels and discarded wadges at her feet, then chomped into the juicy core.

Jamie was not interested in either pineapple, preferring to eat beets and supervise from afar.

Burrito, meanwhile, ate anything and everything that he could find.
