A very happy 36th birthday to the one and only Burrito.
Fog breaks
Waves of dense fog rolled across the sanctuary all morning.
We’d set out for walks when the fog would break but another wave would quickly overtake us. Jody was not a fan.
Missy wasn’t fazed in the slightest.
When the fog lifted it felt almost like spring. Even Negra came out to bask in the warm sun.
By afternoon the fog was gone and the sun was out to stay. Annie quickly went to work gathering snacks. She has taken a real liking to eating raspberry plants – not the raspberries, mind you, but the plants themselves. Because the ones we transplanted last fall have yet to fully root, she is easily able to take them to go.
When you catch Missy standing still, it’s tempting to think that she might be taking in the scenery or sitting for a moment in quiet contemplation. But no. She is just making sure that everyone is watching when she blasts down the hill at full bore.
Sometimes when I am walking around the hill with the chimps, it feels like someone is watching me. And asking for grain.
This morning there were still patches of snow lingering in shadowy sections of the hill. As the day wore on, they were getting harder and harder to find. By late morning, the only source remaining was at the very top of the hill. Either Annie was the only one who knew this secret or she was the only one willing to hike all that way.
Jamie the Tool User
She’s really smart.
Day Nests
At the end of each day, free-living chimpanzees build elaborate nests and go to sleep for the night. These night nests, typically built high up in the crown of a tree, are thought to serve a number of functions including thermoregulation, protection from predators and parasites, and shelter from the elements. According to one researcher who spent time sleeping both on the ground and in chimpanzee nests, they may also simply provide a more comfortable night’s rest. Chimpanzees spend considerable time selecting the proper trees and branches on which to build their nests and then weaving smaller branches and leaves together to form a mattress or basket. This investment of time and energy makes sense; after all, once they are asleep, it is only the quality of their nest keeping them from falling to the ground below.
Day nests, by contrast, are hastily constructed and typically far less structurally complex. They are also more likely to be made on or near the ground. Day nests are simply a place to relax for a moment before the group moves on to another spot.
The chimps at CSNW tend to follow a similar pattern when it comes to the elevation of their nests. Jamie and Foxie in particular regularly make their day nests on the floor of the playroom or front rooms but will make their night nests almost exclusively on elevated benches or catwalks (while Foxie doesn’t build elaborate nests like the others, she does engage in rudimentary nesting behavior). The biggest difference between the nests of the Cle Elum Seven and those of their wild counterparts is that the Seven’s day and night nests are equally complex. Perhaps this can be explained by the fact the the Cle Elum Seven don’t travel very far during the day, and thus they are free to spend as much time in their days nests as they’d like or even return to them throughout the day if they so choose.
In fact, it’s possible that Jamie’s day nests are even more complex than her night nests. This afternoon I watched her make a nest on the playroom floor. With her new favorite boots tucked into her “pelvic pocket,” she twirled fleece blankets in circles around her for several minutes, pushing and pulling each one to form the perfect shape. Then she carefully wove the ends of those blankets through nearby caging, as if to anchor the otherwise unstable nest to something sturdy. She pulled two of her new books close by, one on tractors and another on the chimpanzee children of Gombe, so that she could flip through them as she drifted off to sleep. To top things off, she pulled the last blanket over herself. With each step of this elaborate process she let out a low moan – a sign of contentment.
Jamie’s Mission
This morning, as I was putting away a squeegee, I accidentally knocked a broom off of the tool rack. I watched it slide to within inches of the playroom caging and before my brain could finish processing the thought that Jamie might be able to grab it, Jamie grabbed it.
Now, the most important thing to convey here is that Jamie really likes to stab and/or threaten to stab humans when she obtains contraband like this. So the first thing you do in this situation is take a big step back. Then you watch helplessly as she tries to knock smoke detectors off the ceiling (a real possibility) and jimmy open every door and window in the chimp house (not going to happen with a broom stick, thankfully).
But today was different. As soon as she had the broom she walked off with clear purpose and intent. And the whole gang gathered behind her as if Jamie had given the cue and the secret plan they had been hatching for weeks was finally called into action.
Their mission: To see inside the new addition.
We’ve given them glimpses into the new quarantine and introduction area connected to their playroom before, but during the construction process we’ve largely kept the door covered with a piece of plywood to protect workers from getting spit on and to keep the building heat in. Clearly we didn’t consult the chimps about that plan, and they were forced to take the matter into their own hands.
Night bags
At the end of each day the chimps are each given a “night bag” filled with nuts, seeds, dried fruit, and popcorn. Unlike the rest of their meals, which they typically devour as fast as possible, night bags are savored. It’s as close to meditation as you can get for an animal as frenetic as a chimpanzee.
The New Boot Ritual
Jamie received a new pair of boots from our wish list this afternoon. She has a specific series of rituals that must be followed when she receives a new pair of boots. First, one of the staff or volunteers must wear the boot and join Jamie on a walk around the hill. After returning, Jamie expects the boot wearer to meet her in the greenhouse for a grooming session.
Jamie begins by inspecting the boots carefully.
She encourages the caregivers to show her all of the features of the new boot, such as Velcro or zippers.
Then she begins to groom the boot with a tool – in this case, a wooden chopstick given out earlier as part of a food puzzle.
Eventually Jamie will ask to groom the caregiver herself, pointing and gesturing toward specific areas she wants to groom. Sometimes it’s a freckle, other times it’s a scab or hangnail. She also likes to untie our shoelaces with her grooming tool. Her dexterity is incredible, even when she’s holding the tool with the very tips of her fingers.
With a brand new pair of boots, Jamie will often insist on being given them immediately after the grooming session is finished. With boots that she’s had for a while, she will typically ask for them back when the staff are doing their closing rounds. But you can only give them back to her when she’s ready. If you drop them in the chute too early, she will take them out and throw them back to you (or rather, at you) from an opening high up on the playroom caging. When she is truly ready to receive them, she will wait by the chute and issue a low moan of contentment as they are dropped in. Eventually she will make her nest for the night include them or even use them as a pillow. Only then can you close up for the night, knowing that Jamie is satisfied.
