Chimpanzee Sanctuary Northwest
Hope. Love. Home. Sanctuary
Ya’ll, let me tell you that taking care of chimpanzees in captivity is a job full of stress and worry. But Burrito here, even when you know he can be the instigator of drama, shows us why we do what we do. Enjoy the video and take Burrito’s outlook on life to heart.
We caregivers often talk about Terry’s kind and easygoing personality. He’s not without occasional bursts of machismo, but these emotional tempests quickly subside to reveal his true gentle nature. It’s always a pleasure to be in Terry’s warm presence, and he seems to hold us caregivers in equally high esteem.
Today, I sat near Terry while he industriously processed a paper braid stuffed with seeds and raisins. It’s always nice to see the chimpanzees engaged with their enrichment, and we value opportunities to share those moments with our readers and supporters. On that note, here’s a clip of Terry’s sweet face for you all to enjoy!
It’s been a busy day. Rather than write a detailed blog post, I’m sharing a simple portrait of Annie that I took earlier this afternoon.
Annie was lounging on the elevated platform in her group’s greenhouse enclosure. The chimpanzees who live on that side of the building have been closely watching J.B. and the Sage Mechanical crew as they put in another full day renovating Young’s Hill. I thought her expression (or lack thereof) made for a good portrait. I also included some alternate versions of the image, each edited in a unique way. Let me know if you have a favorite edit!
My “preferred” version:

Jamie is always aware of what the humans are up to and doesn’t shy away from sharing her opinions.
I love Jamie’s dominant personality and respect her autonomous attitude, but satisfying her desires for choice and control is a continuous challenge given the limitations of her captive environment. I am grateful that her outspoken honesty provides some insight into how she perceives her world, allowing us to tailor our caregiving to her preferences. Not all chimps express satisfaction and displeasure quite like she does, accepting a new piece of enrichment with a deep grunt or telling us not to close a door by waving her arm at us. This candid rapport between Jamie and human is extremely beneficial when we engage the chimps socially; Jamie can say “go ahead” or “not now” in her own special way and still be understood.
Jamie demonstrated her forthright demeanor as I was photographing the chimpanzees in her wing of the facility earlier today. I saw her sitting on the bench in Front Room 4, a small indoor area with a good amount of natural light. I saw that she had a single raisin daintily held between her lips and approached to take some photos. Before raising my camera to my face, I pointed to the bulky device and politely asked “Can I take your portrait?” I’m not sure if Jamie understood my request word-for-word, but she nodded eagerly in response. I pressed the shutter over and over again as she patiently stared back into the curved glass of my 85mm lens for what felt like minutes. We exchanged another friendly nod before I moved on to a different location.
I passed Jamie’s perch again as I circled back to the foyer and presented the camera to her again. This time, she ignored my inquiry and just stared back. I had just lifted the viewfinder to eye level with my finger and taken the first two exposures when Jamie suddenly threw her arm up in my direction. I took it as a casual but clear signal that patience for my creative exploits had waned and her participation in the photo shoot was over.
If you’re wondering where Jamie got the raisin…
It was simply a gorgeous early autumn day today. A perfect day for J.B. to lead a big crew of volunteers. It’s so exciting to see the new outdoor habitats coming together, including trees that were recently planted and transplanted bamboo on both sides!
I was sitting with Gordo yesterday while he was gazing at his side of the hill, The Bray. I think he knows it’s for him and his friends.
Jamie and crew definitely know they will be getting a new space, and they have been watching with great interest.
Well, at least some of them have. Jody had other priorities when I was filming today.
Today’s blog is centered around a short video of chimpanzees extracting food from enrichment puzzles.
All of the chimps are given enrichment activities and items every day, but we’re giving additional enrichment to Willy B to keep him entertained while in recovery. So far, his favorite activity has been to tease grapes, walnuts, and other coveted snacks out of the transparent puzzle feeders. These specialized devices were purchased by our supporters from a helpful company, WildlifeToyBox.com. We’re always in need of more durable enrichment items, so Chad has set up a wish list on their site. You can see this special list by clicking here.

Thank you all for your continued support of the sanctuary!
I recently discussed the behavioral training program in this blog post: “Are the chimps trained?”
The post summarized our efforts to improve the chimps’ lives by promoting cooperative behaviors. However, I neglected to mention one of the simplest and most important behaviors of all: recall.
In plain terms, recall behavior is approaching another individual’s location when they call you. Those of you who care for a domestic dog may already know the importance of reliable recalls, especially if your surroundings allow them to be off leash sometimes. In fact, recalls are often the first thing that companion animals learn, either intentionally or by accident, and that’s a good thing.
The chimpanzees are not pets, but we practice this behavior with them to ensure they cooperate when we need them to vacate an enclosure.
This ability is especially important when the chimps have access to outdoor areas such as Young’s Hill and the three greenhouses. Although they are enclosed in a mesh snake fence that prohibits easy entry, snakes and other wildlife occasionally find their way inside the perimeter and end up face-to-face with gangs of screaming chimpanzees. In these situations, caregivers need the chimps to leave the snake alone so it can be safely translocated back outside. Other scenarios that would also necessitate a recall include nearby wildfire, dangerously strong winds, a sudden drop in air quality, or an unexpected problem with the electrified fences.
The chimps in Jamie’s group mobbing a snake in 2018:
Caregiver Grace relocating a non-venomous snake last summer:
A non-venomous racer that Caregiver Chad relocated away from the Chimp House:
As with the behaviors mentioned in the other post, we encourage cooperative recall through the process of operant conditioning using only positive reinforcement. To initiate a recall, one caregiver rings a loud bell and yells “recall!” This combination of sounds serves as the cue for the desired behavior: shifting from the space they’re in into the space closest to the caregiver. When everyone chooses to shift into the preferred enclosure, a second caregiver closes the doors separating the areas. Once the doors are safely closed, the first caregiver marks that as the correct behavior using the clicker and rewards each chimp with a banana.
We give whole bananas every time to ensure the chimpanzees associate the cue and its corresponding behavior with the universally-loved food item. It’s likely that some individuals will occasionally choose not to participate in recalls, in which case we’ll have to “up the ante” with a reward of even higher value.
So far, we’ve had good success getting entire groups of chimpanzees to come in from their outdoor habitats. Earlier today, we asked the chimpanzees in Cy’s group to come into the playrooms so we could rescue a garter snake that had wandered into The Riverview Greenhouse. The entire squad came back inside without objections!
Lucky keeping an eye on the elusive serpent before the recall signal:
Willy B also received banana reward; he is still recovering from his recent procedure but heard the bell and probably would have cooperated if given the chance!
Willy watching the commotion while eating his complimentary snack:
Of course, one way for a chimp to beat the system is to voluntarily stay close to the Chimp House, ready to receive a free banana for staying exactly where they already wanted to be.
