Pretty Fly for a Shy Guy

January 19, 2022 by Kelsi

This is Mave.

And this is Gordo.

Today we continued introductions by doing a one on one with Mave and Gordo. It has been a while since either chimp has done an intro, especially Gordo. He just never seems to be around when we shift for intros, but today he just waltzed into the Mezzanine and I closed the door. Gordo and Mave have met before through other intros, but today was the first time they both were really interactive with each other! When they saw each other they immediately met at the mesh to start grooming. I was waiting for a natural break between them to open the door, but I think they could have sat and groomed each other for hours. Eventually, we opened the door and they greeted each other warmly, but separated for some time. Gordo is a shy guy, so we decided maybe they need alone time. We stepped into the foyer to watch on the camera and within a few minutes they started grooming and playing. Gordo has always seemed to admire Mave from afar so we just assumed in intros that they would interact a lot, but the first few times they would greet and groom each other and then they wouldn’t interact very much after. This intro is such an improvement to their other meet ups and they spent the whole afternoon together.

We Meet Again

January 18, 2022 by Chad de Bree

There were a lot of familiar meetings today.

First, Honey B and Lucky had a meeting with each other. Though things started off slow when they came together, they did eventually did start playing.

As some of you know, Honey B can be dialed to 11 when she plays, Lucky is usually at a 7 on a good day.

All-in-all, their meeting was pretty positive and they seemed to enjoy each others company.

On the other side of the building, the weather finally provided us a break to be able to shovel parts of Young’s Hill. After a few hours of digging out Young’s Hill from the Snowmageddon snowfall by Sam, Anna, Diana, and J.B., Jamie and her group were finally able to go out onto Young’s Hill!

Here are some bonus photos from the day:

Honey B(adger) Don’t Care

January 17, 2022 by Anthony

As many of you know, we’ve been working around Honey B’s odd preferences this winter. She’s a strong-willed individual who voraciously defends her zone of control (which Willy B will attest to). Whatever everyone’s plans are for the day, she has a tendency to shake them up.

Today, Honey B brought more of that same energy.

As she frequently does, Honey declined to shift into the playroom and greenhouse after we cleaned them this morning. Instead, she opted to remain in her beloved front rooms, thus preventing us from servicing them all simultaneously. She watched indifferently as the others rushed out into the larger enclosures.

We’re not sure why Honey B chooses to stay in the smaller rooms; we’ve discussed several hypotheses, all of them equally plausible. Perhaps she prefers cozy spaces, enjoys watching the caregivers clean around her, or appreciates a few moments of seclusion from the other chimps. It’s also possible that she simply likes to introduce a little neutral chaos into our otherwise organized routine. We’ve seen her do just that on multiple occasions.

Whatever her reasoning may be, it’s interesting to watch how this mischievous chimp spends her time apart from the group. Today, she literally hung out in Front Room 7 as I swept, sprayed, scrubbed, rinsed and squeegeed the adjacent areas.

For the first few minutes, Honey B playfully swung on the firehose vines and made an earnest effort to dismantle the fasteners holding them together. Then, she found a toy brush to sweep some nut shells into a small pile. After that, she made a nest in the corner and lounged peacefully as I added fresh blankets and enrichment items to the other rooms.

As far as chimpanzee personalities go, Honey B is definitely on the more human-oriented end of the spectrum. Fortunately, she is also relatively well-adjusted to sharing space with familiar chimps. When I reunited her with her companions after cleaning the rest of their spaces, Honey B politely greeted Mave and Willy B before carrying on with her business elsewhere. All the residents of that wing enjoyed lunch service in their usual configuration and then dispersed out to the playrooms and greenhouses for some afternoon grooming.

Now, as I’m putting the finishing touches on this blog post, I keep glancing over at the new monitors that show our security camera feed. Honey B was just playfully interacting with Terry across the double barrier that separates their respective greenhouse enclosures. I could tell that it was going well by Terry’s exuberant bounces and head nods. They’ve come quite far from their first meeting, during which Honey B went all “honey badger” on poor unsuspecting Terry.

Whether she’s being asked to shift to another area or being introduced to a new friend, Honey B never lets things get boring around here.

P.S. If you didn’t get the “honey badger” reference and are feeling adventurous, you should do a YouTube search about them. I’m referring to the 2011 video with 98 million views. I’d post the link but the language used in the title is absolutely NSFW and thus not safe for the blog either…

For the Chow!

January 14, 2022 by Kelsi

This morning Negra thought we should all go back to bed! Sometimes, no amount of peanuts is worth it, but chow… chow can be motivating!

Negra tried really hard to keep her eyes open.

But the grogginess had overcome her.

Yet, she still tried her best to wake up! She could hear the smoothies being blended and the chow being counted!

For the chow Negra blinked her eyes open!

But alas she closed her eyes again!

One bonus of Rayne with a mouth full of chow!

Jump Jump

January 12, 2022 by Kelsi

As we have discussed many times, Cy is an avid reader. With some kind donations of Shutterfly gift-cards we finally made Cy his book! The pages were filled with Mave’s group, Jamie’s group, the cattle, and of course lots of spreads of Willy B. Cy is constantly flipping through magazines and we have never seen him so startled that he jumps, but when he saw the pictures of the cattle he jumped out of his skin! The first time he even made me jump! Eventually, Rayne took care of it for him and ripped the book up. She is a true friend! Since Cy’s new book didn’t work out, we are running dangerously low on magazines. Cy has been dying to get his hands on some People magazines! If anyone has clean magazines they could spare, we (Cy) would greatly appreciate it!

Let’s Talk About Enrichment

January 11, 2022 by Chad de Bree

Taking care of chimpanzees is more than cleaning enclosures and serving them meals. There’s a lot more that goes into it. We also ensure the chimpanzees are well mentally. This is usually through the form of enrichment. Enrichment is a way to provide mental stimulation and promote natural behaviors. In layman’s terms, enrichment is a way to try to curb boredom. When animals become bored, some abnormal or stressed-related behaviors can start to develop.

Here, we try very hard to keep all 16 residents enriched to the best of our abilities. But what does that look like? Traditionally in the animal care field, enrichment comes in a few staple categories:

Cognitive
Physical Habitat
Social
Food
Sensory

Cognitive enrichment is the form of enrichment you have seen here many times. These are the food puzzles the chimpanzees get throughout the day. These are the toys some interact with. This is a way for the chimpanzees problem solve and give them a level of control of their environment. With the food puzzles, its a way to problem solve a situation in order to achieve the reward.

Foxie strategizing how to extract the peanuts in the Boomer Ball. Each chimpanzee has their own way of extracting the peanuts from these. Some shake them until the peanuts eventually fall out. Some try to fish them out with a tool. While some, like Foxie, tries to dig them out with her fingers.

Jamie wearing a Troll Scarf. We never tell the chimpanzees how to interact with their enrichment or tell them to wear clothes. That would defeat the purpose of sanctuary. With Troll Scarves though, Jamie usually likes to wear them around.

Burrito plays with a giant orange ball. Burrito particularly loves rolling these around and making as much noise as possible with them.

Physical Habitat is the how the enclosure is set up. Not only should an enclosure probably look visible appealing for the chimpanzees, but it should be functional as well. Young’s Hill has a plethora of structures the chimpanzees can climb, swing, and sit on to look out on to the surrounding areas. In the indoor enclosures, firehose is a great addition to their physical habitat.

Lucky is a big fan of lounging around or sitting on the firehose when she is inside.

In the two new playrooms and greenhouses currently occupied by Willy B’s group and Cy’s group, there are two artificial trees the chimpanzees can climb up and relax on their platforms.

Social enrichment is the relationship the chimpanzees have with others, chimpanzees and humans. It can be enriching to interact with a chimpanzee from another group, even if it is just through the window.

As you know, we have been in the process of integrating Cy and Willy B’s group into one. Though these times can be stressful, seeing some of the chimpanzees come together and form bonds is the most heartwarming feeling a caregiver can get.

Just yesterday we were serving dinner and Cy and Willy B were both unusually absent. I went to find them, and found them at the new window to each other in the Greenhouses.

Food can be exciting and enriching, but food on it’s own is just something you eat to satisfy an empty belly. What can make food more enriching is introducing new foods or presenting it in new ways. We are continuously trying to find new foods to introduce to the chimpanzees. We also try to present the food in different ways. Besides hand serving we also set up forages. Typically when the weather is nice, we set up forages on Young’s Hill. This promotes a chimpanzee’s natural behavior to move around and search for their food.

Jamie grabs all that she can as she searches Young’s Hill for food.

Another type of forage presented in an exciting way is the parties we throw.

Here are some photos from 2021 Jamieween!

Sensory enrichment includes those which allow the chimpanzees to utilize their sense of touch, smell, auditory, and vision. We try to provide them with novel ways to utilize these senses.

One of the touch enrichment we use is play sand. Here you can see an imprint of Honey B’s foot in the sand box. Every so often, we would see Honey B, Jamie, and some of the others just grab a handful of sand and let it sift through their fingers.

As some know, Willy B loves screen time. This is one way we provide him with both a visual and auditory enrichment.

While Sam showed Willy B some videos, I showed Honey B and Mave some videos of our friends at Center for Great Apes.

Is everything we do a hit? No. Is what is good for one group good for the other? No. Do we continuously try to find ways to ensure every chimpanzee is enriched based on their personal preference and likes? Absolutely! Though this can be a very challenging task to cater enrichment for 16 very different personalities and likes, it is absolutely worth it. It is part of the job I personally love.

Work Hard, Display Hard

January 10, 2022 by Anthony

Originally, I planned on writing a blog post for today by following my classic recipe of egregiously bad puns, unnecessary history/science lessons, and some recent photographs of the sanctuary and its residents. In particular, I was going to share a series of images that would convey to everyone just how much snow we have piled around us after “Snomageddon” (and how hard we’re working to keep our paths and entrances clear). I’ve still included those photos here, but Willy B actually stole today’s blog with some mischievous behavior.

Before I elaborate on Willy’s exploits, I’ll have to provide a little context. In the newer wing of the Chimp House, the two former Wildlife Waystation groups reside in two sets of enclosures that essentially mirror each other; this layout enables each group to have access to a playroom, greenhouse, and either the mezzanine or front rooms for most of the day. We try to briefly close the chimps out of each area for daily cleaning, sometimes requiring us to play a weird version of Rush Hour to get things done. Lately, I’ve been experimenting with different strategies when I’m responsible for operating doors and shifting chimps around, and I have had some luck with a new shifting pattern in recent weeks. With all that promise, it was only a matter of time before I fell on my own sword.

This morning, everything initially went well and all the chimps shifted for breakfast. Amid the second round of shifting, during which Honey B usually decides to employ the filibuster to stall our caregiver agenda, it was actually Willy B who derailed my plans.

I had just successfully rotated Honey B, Mave and Willy B into the clean front rooms and invited the six chimps in the neighboring group to cross over from one playroom to the other. In that moment, Willy grabbed one of the bulky rocker toys in Front Room 5 and started drumming on it, causing the whole building to quake with every hit.

Chimps are generally quite preoccupied with their neighbors and are susceptible to social contagion (scientists call this combination the “Neighbor Effect“), so you can imagine the pandemonium that can evolve from one chimp’s abrasive behavior. In today’s case, the whole sanctuary stopped what they were doing to monitor Willy’s incessant banging with the utmost concern. With so much to be worried about, the six chimps in Cy’s group milled around the accessible spaces, occasionally responding with short outbursts of their own while completely ignoring my invitation to switch playrooms. Still, Willy B kept beating on the available surfaces at the expense of our eardrums.

It’s known that chimpanzees display for various reasons (to influence their group members, advertise their fitness, express their emotional state, cope with tension, etc.), but its difficult to identify a clear motive for any single occurrence of this behavior. Thus, we can’t know what caused Willy B to ceaselessly drum on the furniture today, but we can attest that he continued to do so for the better part of an hour while we all tried to stave off headaches. Perhaps his ultimate goal was simply to spice the morning up with a bit of mayhem.

Eventually, we were able to entice Cy’s group out of the messy playroom long enough to close it off, but it took quite a while to get to that point. Even once we had safely unlocked the enclosure, we had to clean them to the rhythm of Willy’s clamor. We expected that the display would culminate in some sort of conflict within the social groups, but Mave rescued them all from that fate. Amid a break in the commotion, Mave hooted, bounced over to Willy B, and pant-grunted right in his stoic face. Perhaps Willy had wanted that acknowledgement all along, or maybe he was simply growing tired and Mave had seized the opportunity to interrupt in the only way she knew how. Either way, the submissive pant-grunt punctuated the relentless drumming that was holding us all hostage, bringing Willy’s uproar to an end.

In addition to the embedded video, I’ve included the aforementioned photographs below. Be safe and have a good week, everyone!
