The new door

by

On Sunday, the chimps got to use the new door for the first time. We do our best to keep things interesting around here, but the facility itself doesn’t change that often, so the chimps are always very excited and very curious to see the improvements. 

Anytime there is a major change, whether in the social group or in their environment, the chimps like to reassure each other and seek comfort amidst the excitement. You’ll notice a lot of greeting, hugging, and submissive behavior in this video (Foxie kissing Burrito, Jody greeting me with a “genital bounce”, Annie kissing Jody, Annie and Missy submitting to Burrito who is off-camera). 

We serendipitously discovered that the chimpanzees appreciate having fire hoses hanging just outside the door. The hoses were there previously, but once we installed the door, many of the chimps used them to climb from the door up to the the platform outside without setting foot on the wet ground. That’s one of the strange things about caring for ex-lab chimps (any captive chimps, really). Wet ground is a fact of life for free-living chimps, but it can be unpleasant and even terrifying for individuals who have spent a lifetime indoors. We used to place tractor tires outside so that Foxie could use them as stepping stones, but now we’ll have to hang some more fire hose by the other door.

Displaying

by

Given that we share around 99% of our DNA, it is not surprising that chimpanzees and humans have much in common. Both species, for example, are very territorial. We might not think of ourselves as territorial creatures, but imagine how you might feel if you looked out your living room window and saw a stranger standing in your front yard peering in at you. Free-living chimpanzee communities will defend their territories, sometimes violently, against intruders from neighboring communities. (Sound familiar?)

One of the ways chimpanzees express their territoriality is through a display. During a display, a chimpanzee stands bipedally (upright); swaggers back and forth; makes a lot of noise by banging or throwing objects; and exhibits pilo-erect hair (hair standing on end). All of these behaviors serve to make the individual appear much bigger and more intimidating than he or she really is.

Defending a territory isn’t the only reason a chimpanzee might display; displays can also be associated with dominance. Jamie, who is the most dominant member of the Cle Elum Seven, displays several times a day. (Although it is almost always male chimpanzees who display in free-living situations, it is not uncommon for females to display — and to be dominant — in captivity.) Jamie displays to defend her home, to exert her dominance, and even, it seems, to alleviate boredom.

Below is a video of one of Jamie’s displays. You’ll notice many of the behaviors I described above. Despite spending the last three decades in the most unnatural and impoverished situations, it seems Jamie has figured out just how to be a chimpanzee.

A new game

by

Missy and Annie are playful in the morning, sometimes chasing each other all over the playroom before we even turn the lights on. Lately, they have been playing a new game: chasing each other while balancing on the catwalk railing. I finally caught them in the act the other day. Good thing they have opposable toes….

More construction!

by

We spent the last two days installing the new pneumatic door that will allow the chimps to go from the front rooms directly to the outdoor area. The door is in, but there’s a little more work to be done before the chimps can have access to that area. Hopefully we will be able to post photos of the chimps using their new door this weekend.

I’d like to thank the very generous – and very patient – donors who made this project possible. It took a little longer to complete than I had anticipated, but thanks to you, the chimps will soon have more freedom to move around the sanctuary as they please.

Missy and her raisin board

by

We included raisin boards in this morning’s enrichment, and Missy demonstrated a new technique for fishing the raisins out (at least one that I haven’t seen before). Rather than trying to pry the raisins out or poke them out the other side, she would insert the chopstick and push it all the way through, like she was sewing with a big needle. It seemed to work well, except for when her tool would get stuck, in which case she would just break it off and start over with a smaller stick.

Negra

by

When you take care of chimpanzees in a sanctuary, your whole life revolves around trying to make them happy. You live for those moments when they are food squeaking over a good meal, or playing a wild game of chase around the outdoor enclosure. For some members of the Cle Elum Seven, we’ve begun to take these moments for granted. When does Missy not want to play chase? And is there ever a moment when Foxie is not playing with her troll dolls?

But for some chimps, its harder to tell when they are happy. Negra has one speed (slow) and a limited number of activities that she engages in (eat, sleep, groom, gaze out the window). Perhaps its due in part to her personality; some folks just live life at a different pace. But you can’t help but wonder how much of it is due to 35 years of confinement in a laboratory.

Determining what effect a lifetime of stress in the laboratory has on chimpanzees is currently the work of two researchers, Debra Durham and Hope Ferdowsian. Debra and Hope are conducting a large-scale study of post-traumatic stress disorder (PTSD) in ex-laboratory chimpanzees. This summer, we participated in interviews with the researchers to look for indications of PTSD in the Cle Elum Seven.

Debra recently penned an Op-Ed for the Orlando Sentinel (see Drawing Ourselves into the Lives of Chimpanzees), in which she comments on the improvements they have seen in Negra. And, as fate would have it, the article’s publication coincided nicely with this video we took of Negra playing with Missy right before Jamie’s birthday party. (My favorite part of the video? When Negra grabs both or Missy’s ears and shakes her head back and forth 🙂

Its not likely that Negra will ever be rambunctious like Missy, or acrobatic like Foxie. Usually, I take comfort in the fact that when Negra chooses to put a blanket over her head and stare out the window, at least she has a choice. But she does have her playful moments, and according to Debra and Hope’s research, she is still showing signs of improvement.  So we can all look forward to seeing Negra pull Missy’s legs and ears more and more in the days to come.

On the radio

by

Arik Korman, the director of 102.5 KZOK’s The Bob Rivers Show, recently visited the sanctuary. Arik has shared a podcast full of great questions, a dramatic intro and some terrific audio of the chimpanzees food grunting (in the beginning) and Jamie displaying (toward the end).

You can learn more about the sanctuary and chimpanzees by listening to the podcast linked to below or hear it broadcast on KZOK this Sunday in the 6am hour, KJAQ in the 7am hour and on AM 1090 in the 11am hour.
