Enrichment

The Gang Goes Counterclockwise

by

Chimpanzees thrive on routine.

Of course, we don’t want every day to be exactly the same for them. As caregivers, we strive to provide the chimps with an enrichment program that balances variety and predictability, which is a never-ending challenge. The result is that we work hard each day to facilitate a range of new experiences for the chimpanzees within the framework of a regular schedule. Knowing what’s going to happen next helps the chimps to plan ahead, make choices, and be agents of their own comfort and happiness.

Jamie enjoys boomer balls, an enrichment device that we prepare once every few weeks. The chimps get some form of enrichment device each morning, but the type varies from day to day.

With so many new events occurring at the sanctuary, sticking to a familiar routine also seems to help the chimps adjust to each change. For example, even though Jamie and the Girl Gang are now residing in a previously unfamiliar area of the Chimp House, we still provide them with their favorite enrichment items at the same time each morning, serve their meals on the same schedule, and open the hydraulic gate each day so that they can explore Young’s Hill.

Fall at the sanctuary (Note: there’s a wild Nutmeg hidden in the background)

We’ve had some perfect fall weather for the past few days, and the Girl Gang (Annie, Foxie, Jamie, Jody and Missy) have been eagerly spending time outdoors. Just this weekend, J.B. and a group of committed volunteers built a new multi-level wooden structure on Young’s Hill. As Kelsi noted yesterday, the females were quick to investigate this new addition to their habitat. Even though nobody modified or enhanced the structure overnight, the girls needed some extra time today to reacquaint themselves with the new tower.

Annie warms up in the sun.
Foxie surveys the landscape from the highest perch.
Jamie conducts what appears to be an OSHA inspection.
Jody squats on the fresh grass growing around the tower.
Missy hangs out on the lower deck of the multi-tiered platform.

The new structure is located near the entryway into the chute. Now that they’re in the new area, Jamie and the others access Young’s Hill via the chute and therefore begin their patrols over on the southeast corner of the enclosure. Even though their patrols no longer start over by the Greenhouse door, they still walk in the same clockwise direction as they have since they first started exploring the Hill almost a decade ago. I have never seen them patrol in a counterclockwise direction. Just a few days ago, I jokingly asked J.B. if we could try to get Jamie to walk counterclockwise around the Hill with us. He dryly answered “No. You can’t do that.” We agreed that Jamie has a routine and it would be a crime to disrupt it.

So, when I opened the hydraulic door and the chimps hustled out of the chute onto the Hill, the unthinkable happened.

*** Imagine that the iconic jingle from the It’s Always Sunny in Philadelphia title card is playing right now ***

Anna and I were quite stunned when all five of the females started plodding their way uphill along the southeastern boundary of the enclosure. Missy led the charge, of course, but Jamie seemed a bit apprehensive about the whole thing. She started to follow the others, then fell behind, and was soon looking back at Anna (who was watching the events unfold from outside the electrified fence).

Sure enough, Jamie returned to the bottom of the slope and began to patrol in her normal clockwise pattern, gesturing at Anna to follow along. She encountered the others about halfway up the northwestern boundary and it was hella awkward. As Jamie trudged past each of the others, they had to stop and greet each other with a touch and a chimp kiss. Then they all just stood there, lined up along the fence, and watched her defiantly continue up the slope on her own.

Jamie passes Missy…
…and Annie…
…and Jody…
…and then leaves everyone behind…
…including Anna.

Jamie seemed a little off after that, because she abandoned her patrol, ditched Anna in favor of the Twister, and cut straight through the bamboo forest on her way back to the chute. Jamie can handle wildfires, social integrations and even snakes, but going counterclockwise around the Hill is too much.

This exemplifies the power of routine. Some chimps, such as Jamie, have personalities that seem to thrive on discipline and repetition. She likes to be in control. She did three patrols today, walking at the same pace in the same clockwise direction using the same path. The other four females, who tend to be more easygoing, didn’t seem scared by the idea of hiking the trail backwards.

Of course, there is the possibility that Jamie, like Derek Zoolander, cannot turn left. Let’s not rule that out.

New Space

by

While we are on a bit of break with the introductions, Jamie, Missy, Jody, Annie, and Foxie are spending their time in the new Phase 1 area of the building. Foxie was with Burrito in there for about a week, but Wednesday was the first time the others got to go into that space (and the chute too!).

I wasn’t able to get any good photos of them in the chute (or when they went on patrol on the hill) today, but here they are enjoying the new indoor rooms:

Then grooming upstairs in what we are referring to as the mezzanine:

Willy B and the Tale of the Slinky

by

Willy B’s wild side is out and we have proof! Willy loves slinkys as we may have talked about before, but today he took it to another level. He was wearing it around his ankle and kickin’ his legs, he was wrapping himself in it, and he was flipping upside and flinging the slinky around! If you don’t believe me just check the video out for yourself. If you weren’t smitten with Willy B enough, get ready to love him even more! We are so glad to have these 3 new additions at Chimpanzee Sanctuary Northwest and it is so fun to get to know Willy B, Honey B, & Mave more and more everyday.

 

Jamie Project Day!

by

Everyday we have a different theme for enrichment. For example, yesterday was cover the floor day where we literally covered the floor with items such as blankets, toys, and forage! Today just so happened to be Jamie project day! There are so many different projects Jamie enjoys, most have to do with construction, power tools, the gator, and so on. So we settled on a few things, some reading material, a new tool set, and a new puzzle too! Our kind donors donated new toys off our Amazon wish-list!

Jamie seemed quite pleased with these new tools, but Jamie really had her eye on the tomato garden!

Jamie brachiated her way over:

And than sauntered by to tell me know it was time for tomatoes:

Meanwhile Annie, Jody, and Burrito groomed each other and stared off toward the chute:

Yesterday the chimps also got wood wool, which they made beautiful nests with. Each nest was different, some intertwined, some on top, and some not used at all (also very messy):

Jody enjoyed some morning sun:

Mave and Willy B spent a little bit of their day grooming each:

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.

 

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.
