Why We Puzzle

by

Raise your hand if you like to do puzzles.

There are lots of different kinds – jigsaw puzzles, word puzzles, logic puzzles, math puzzles, etc, etc. Remember the Rubik’s Cube fad? Or perhaps you are mechanically-minded and like to figure out how things come apart and go back together. Maybe you’re more of a physical person and you like to do actual obstacle courses. Video games are really electronic puzzles, and we know how popular those are.

There was an increase in humans doing puzzles this last year during the pandemic and lockdowns. I’ve read a few articles about why we humans like to puzzle, and the explanations generally include things like: puzzles provide us with a sense of control, and when we solve a puzzle our biology rewards us with a chemical hit of dopamine. There’s some intriguing research showing there’s more than just a dopamine surge going on in our brains when we we are working on puzzles.

We, as primates, are hardwired to solve problems. We often do it all day long, and even choose to do it in our leisure time.

Why am I talking about this?

At the sanctuary, we provide the chimpanzees with food puzzles. A few of them have been featured in recent videos, like Honey B and Willy B acing Anna’s inspired Slinky Madness puzzle and the video that J.B. shared last week of Honey B  fishing out a peanut from a boomer ball puzzle.

On both of those video posts on social media, there were a couple of comments that questioned whether the chimpanzees were being led to frustration with these puzzles. There was even the notion that the puzzles were cruel.

A long-time blog follower, Dan Oksiuta, responded wonderfully to one such comment by saying, “While the puzzles & caging may appear unnecessarily frustrating, it is reasonable to assume they experience the same emotions of accomplishment & satisfaction as humans completing a difficult task. Treats probably taste better, too.”

Thank you for that, Dan!

The food that we include in food puzzles is a really minuscule amount, and it’s outside of their regular meals, so they aren’t choosing to solve puzzles out of hunger. They have a similar drive as we do and receive similar intrinsic rewards for solving puzzles (plus the sweet reward of a peanut isn’t nothing).

For those who have been following the sanctuary for a while, you already know that Jamie is a chimpanzee who often prefers to use a tool to get food instead of having it handed to her. Jamie’s brain seems especially wired for problem solving.

Just like humans, not all chimpanzees are the same. I don’t think I’ve ever done Sudoku and really most of my puzzling and problem solving is more of a practical nature (i.e. “how can I fit just one more houseplant on this table”).

Burrito used to be pretty bad at solving food puzzles, giving up rather quickly. As the years have passed, though, he’s gotten quite accomplished at puzzle solving. Even in the early days, when his puzzle solving wasn’t what it is today, he was eager for the nightly enrichment.

Negra, who is not known to exert extra energy for much of anything, delights in all sorts of food puzzles; in fact it’s a rare evening when she’s not clapping for her caregivers to hurry up with the distribution of the night enrichment. She might prefer the easier enrichment, like peanut butter in between the pages of magazines, but she’ll engage with even the more challenging puzzles before bedding down for the night.

An aside, take a look at our Enrichment Database for examples of the food puzzles as well as the more generalized enrichment we provide.

Boredom is the ever-lurking nemesis for primates in captivity. It can lead to depression and all sorts of strange behaviors. Providing ways for primates to problem solve is one way to keep boredom at bay.

Actually, you could consider forages to be giant food puzzles. When we spread out food, sometimes hiding it, the chimpanzees have to locate and gather their food, and they are in somewhat of a competition with the others in their group. This is an important skill to have and develop when you are a species that must find ripening fruit in the jungle.

Images or videos of chimpanzees in captivity foraging for food, especially if they are outdoors, rarely if ever results in people commenting that it must be frustrating or questioning why we don’t just hand them food (we do that type of serving too). I think it comes back to our superficial, knee-jerk perceptions of animals in captivity. We want to see them in “natural environments”, not necessarily because that’s what they like the most or what’s the most enriching, but because that’s what makes us feel the best.

So, food puzzles hanging on caging just doesn’t sit right with some people. We hear you. We don’t think chimpanzees should be in captivity either, but they are. I wrote a little post called What is Natural a long time ago that addressed something similar.

The thing is, a chimpanzee working on a food puzzle indoors in captivity is a good thing, as long as they also have access to the outdoors, live in a social group, and have a wide variety of other ways to alleviate boredom and do the things they are hardwired to do. It’s as least as natural as a human solving a Sudoku puzzle on their couch.

Here are some photos from today of chimpanzees problem solving:

Foxie with a purpose:

Jody with her forage haul, heading back to the greenhouse:

Jody experiencing the sweet rewards of a successful forage:

Willy B is still the only one of his group of three who will venture into the open Courtyard. Mave and Honey B are more comfortable inside and in the Chute. We’ll be thinking of ways to help them look at the outdoors differently and are hopeful that their expanded space will help, but, in the meantime, we make sure the spaces they do spend their time in have lots of things for them to do.

The next two photos aren’t great, but they show that we put some lettuce on top of the Chute for Mave and Honey B while Willy B went into the Courtyard to get his lettuce.

The photo below is of Mave up high in the Chute pulling the lettuce through. She spends a lot of time with this food puzzle, which we’ve just recently introduced:

Honey B really likes to “groom” pebbles out of our boots. There’s no food reward, but she clearly gets a lot of satisfaction out of this task.

J.B. put lettuce at the top of the structure to entice Willy B to do some extra climbing in the Courtyard.

Sometimes it’s fun to watch other people work. Here’s Mave and Honey B watching J.B. painting murals on the other side of the window.

 

Odds & Ends

by

Every so often, I get that dreadful warning that my phone’s memory is almost at capacity. I have a certain degree of confidence I am not the only one here who constantly takes pictures with their phone, thinks “This would be great for the blog,” then forgets about them when our day to write a blog comes around. There is just so much that happens that it’s hard to share every single photo we take, especially those taken on our phones of these by chance instances.

So without further ado, here are some of the photos that have been sitting in my phone’s memory bank:

Mave relaxing. I had at one point thought to write a blog about primate feet, specifically the differences between ape feet. The furthest I got was getting this photo of Mave’s foot to show just how similar and different they are compared to ours.
Foxie food peering at Negra, hoping she was in the mood to share her breakfast even though she had already eaten her own. Spoiler: Negra was not in the mood to share hers.
Speaking of food peering, Willy B peering at Honey B wondering why she was so excited. On this day a couple of weeks ago, we served a very ripe jackfruit. Willy B had zero interest in it at first and threw his to the ground in protest. Honey B on the other hand, knew exactly what it was and ate hers in a haste and collected as many of the ones Willy B discarded as she could. There may have been some buyers remorse on Willy B’s end, though he ended up taking some of the corn Honey B discarded. Seemed like a fair trade.
When cleaning the playroom, if I am near a certain window scrubbing, I usually get a little surprise from Burrito, who seemingly appears out of no where. One day, I figured out just where he pops up from.
Mave. Just Mave. Does this photo really need any further explanation?
Burrito enjoying his breakfast oranges sitting in a cube chair.
Foxie hanging upside down, laughing in one of the Front Rooms. Play is usually her tactic for me when she doesn’t want me to close any of the doors. In this case, she didn’t want me to close the Front Rooms to allow us to clean.

Honey B decided her red skateboard needed some adjustments to it.
Barn Kitty waiting for a staff member to arrive at the sanctuary in the morning to feed him.
In case you didn’t know, Barn Kitty is a semi-feral cat who has called our barn home from time-to-time. So we have a little area in the barn for him to use or not use. It’s his choice.

There is one photo from today. Spring is officially here! And to celebrate this wonderful season, Jamie has decided there needs to be a couple more patrols around the Young’s Hill before she will allow the staff to close it up for the night.

And if you haven’t heard, we will be participating in the Global Primatology Virtual Conference hosted by Central Washington University and the Primate Awareness Network. We are scheduled to present March 25th (this Thursday) at 4:00PM PST. Be sure to also check out some of the other amazing speakers!

Volunteers Behind the Scenes

by

Last week I wanted to focus on Spring Negra, which meant there were some photos that didn’t make the cut for the blog. Luckily, I just remembered them! Look no further than the end of this post for the non-Negra photos from last week’s lunch forage.

But first, a word about volunteers.

Probably everyone reading this knows that the pandemic has drastically reduced the number of volunteers that are onsite helping with the daily operations of the sanctuary. There are currently just two volunteers who have basically been additional part-time staff members, cleaning alongside us and trying to keep up with Burrito. We owe them a huge amount of gratitude for all of the hours they’ve worked.

In addition to halting our regular volunteer program, we also put the Central Washington University daily intern shifts on hold until we feel that we can safely loosen restrictions without putting the chimpanzees at risk.

Volunteers and interns have been helping in other important ways, however.

They have been making paper braids in the shed near the chimp house, proof-reading marketing material, delivering totes brimming with lovingly-rolled chow bags, organizing community outreach events like the art contest and upcoming showing at Gallery One in Ellensburg, helping write grant proposals, entering historical medical data into new software, painting mountain murals in the new playrooms (we’ll share photos soon!), helping plan virtual fundraisers (The Queen’s Brunch coming to a computer near you on June 13th), and much more.

While volunteers continue to contribute to the smooth operation and outreach efforts of the sanctuary, our all-volunteer board of directors focuses on the really high-level behind-the-scenes work that you may never even hear about, like creating policies that ensure the sanctuary as an organization can carry on the vision of helping primates for a long time to come.

This strange past year has provided a lot of lessons and new perspectives, but, no matter what, we will remain grateful to those who choose to give their time to help the chimpanzees and bovines too. The sanctuary wouldn’t be what it is today without the unpaid yet hard and important work of so many people.

Thank you all!

Here are those promised photos. This first series is, “Foxie and the Carrot”:

 

This is simply: “Missy in Profile”

And this I was going to call “Burrito with Tomatoes” but I realize that might be confusing… so perhaps, “Burrito Enjoys a Forage Break” is better:

Rejoice

by

Spring is still in its infancy in Cle Elum. The nights are cold, and we will likely see more snow, but it will be the kind of snow that is there one minute and gone the next. There’s no holding back the change in the seasons now.

This change from winter to spring is often the most dramatic. It surprises me every year. I don’t forget that the days gradually stretch in synchrony with the plants reaching for the sun, but I do forget what it really feels like. I can’t seem to conjure up the experience unless it’s authentically occurring.

I remember that the group of seven chimpanzees spend more time outside, and that we often scatter their meals out across Young’s Hill, the two acre habitat. We have thousands of photos of this. But still, watching and feeling the first forages of the season is familiar, but also new all over again.

This winter was, overall, remarkably mild. You may recall that we had a very notable Christmas celebration forage on the hill on December 19th. It was notable because Negra climbed up to the lookout for the first time in pursuit of a pineapple top. Go ahead, go re-live that glorious day.

Today we set out a lunch forage for the group of seven. Negra was the first one out of the raceway and onto the hill. She didn’t go even halfway up the hill, but she did seem to be remembering, like me, what spring feels like.

I couldn’t help but take a ridiculous number of photos of her as she sat, as she stretched to reach pieces of food, and as she walked, in all her glory, back inside. I encourage you to pause on each of the photos and remember. Remember that feeling of warmth and life and hope.

Maybe there are more pineapple climbing adventures in Negra’s future. But, even if there are not, today’s emergence was fulfilling.

 

On the other side of the building, Willy B spent some time sitting on the boardwalk.

We did a forage of a different sort by placing lettuce on top of the chute. I didn’t get any great photos of this forage, but Honey B, Willy B, and Mave all partook of the bounty, with Mave in particular getting into the foraging spirit.

In just a few months, the three will have new spaces to explore while we will work on creating their version of Young’s Hill that will be called The Bray. And six more chimpanzees will join that side of the building.

There’s a lot of hope in the air.

Morning Adventures and Afternoon Naps

by

The staff will continue our positive reinforcement training this afternoon. But before we dive into our training, here are some photos of some chimpanzee adventures and naps.

Jody eating her breakfast clementine orange while looking out onto Young’s Hill.
Jody, Foxie (above) and Missy (below) take in this morning’s scenery from a platform after going out onto Young’s Hill.
Burrito later soon joined Foxie on the platform after Jody and Missy left.
Annie took some time for herself high above the bamboo on Young’s Hill. She later joined Missy and Jamie on a patrol around the parameter.
Foxie embraces one of her new Strawberry Shortcake dolls on the top platform in the Greenhouse.
Jamie embracing a cowboy boot while snoozing off. You may wonder why she doesn’t elect to lay down while taking her afternoon slumber. She is the boss you know and has to be ready to go at the drop of a hat. This photo was from yesterday, but Jamie is currently in this same position and I couldn’t get a better photo from today.

Don’t forget to vote for your favorite piece of art! The three designs with the most votes will win the People’s Choice awards! So be sure to vote before March 14th!

little random moments

by

The video above is a little bit random, but the days are a little random.

Little moments catch my fancy, like Jody with her great big eyes and Jamie and Burrito running with the Gator.

Spring is definitely in the air. The killdeer and red wing blackbirds are calling, the trees are starting to bud, the bovines are shedding their extra winter hair, and Mave is sunning herself at the top of the chute.

It’s the simple and subtle things that pull me forward towards the next day of random moments.

Unexpected Gift

by

Do you know the word lagniappe? It’s an American French (think Louisiana) word. From my perusal of dictionary definitions it refers to a bonus “something” given to a customer when they are making a purchase. It’s now used in broader terms and refers to any unexpected bonus that comes with something else.

I’m glad I looked it up! I’ve liked the sound of the word since first hearing it and sometimes it’s just floating around up there in my head for no reason. But now I realize that my understanding of the definition as simply “an unexpected gift” was somewhat incorrect.

On Thursday afternoon, J.B. headed out with the sanctuary truck to pick up the weekly produce, which was much needed because the fridges were looking quite bare with the glowing exception of a particular fruit that I believe Anthony will be writing about tomorrow.

I want to say that the filling up of our fruit fridge was a lagniappe, but that would be using that unique word incorrectly – it was just a wonderful and unexpected gift.

I digress.

In the middle of a zoom call after J.B. had left to get produce, I got a call from him on my phone. I decided I should answer it because it was strange that he was calling me just 20 minutes after leaving. I rudely existed the view of my computer camera with no explanation and took his call. Indeed, my intuition was correct. The truck had an issue and he was parked on the side of the highway. There would be no produce run that day.

Instead, after the truck was towed and I picked up J.B., he made a quick jaunt to the local grocery store to hold the chimps’ over until the truck was fixed and he could do the full produce run this afternoon.

To my surprise, one of the produce items he brought back was corn. Corn! In February! This was indeed a lagniappe. Oh wait, no – that’s using the word incorrectly again.

Nevertheless, the chimpanzees were delighted with this unexpected gift:

Negra:

Missy:

Jody got two ears because Jamie was at first very focused on the mini sweet peppers at lunch, putting her ear of corn down near the watchful eyes of Jody. Jamie was okay with Jody taking it, but decided later she did in fact want some (maybe the sounds of all of the delightful crunching by her friends made her change her mind). If you are on Instagram, go to our page to see a little video clip of Jody crunching her double lagniappe gift.

Everything worked out in the end because Foxie rejected her corn full stop. So, I gave Jamie Foxie’s ear of corn and I gave Foxie Jamie’s carrot.

Whew!

Jamie took her corn up to the top window for some private dining.

Honey B, Mave, and Willy B got their corn for dinner and it was very much appreciated by all three of them. Here’s Honey B:

Thank you for all of you Produce Patrons out there who help provide the chimpanzees with much loved and unexpected gifts of fresh fruits and vegetables!

Side note – if anyone knows of a word that actually means “unexpected gift”, I would like to know! I might send you something as a thank you for your linguistic prowess.
