I took this photo of Jody in a nest in the greenhouse this afternoon:
and when I looked over a few minutes later Annie had taken her place:
Sanctuary
Close friends
It’s so relaxing to watch the chimps groom one another. Grooming is often used as a way to, not only help clean up your friends, but also to strengthen bonds and friendships. Foxie and Burrito have a pretty close friendship and I caught them in the middle of a very sweet grooming session this afternoon.
Food grunts and breathy pants
One of the things that I like about the GoPro camera is that you can hear some of the sounds that the chimps are making when they are way out on the hill. In this video, you can hear food grunts from Jamie and Jody and of course a couple of Burrito’s famous food squeaks.
You can also hear Foxie’s breathy panting as she reassures Burrito. Chimps will often reassure one another with vocalizations like this, as well as through touch and embrace, when the potential for conflict exists. If there is a limited resource, like nuts and seeds spread on the ground on Young’s Hill, the chimps will sometimes try to make nice before a conflict erupts over who stole food from whom, in an effort to prevent this kind of conflict. Normally, the chimp receiving the reassurance would provide some sort of acknowledgement, but that’s not Burrito’s style – he prefers to close his eyes and pretend that uncomfortable situations don’t exist.
Blanket fort play
The enrichment at the sanctuary changes daily, and we try to come up with different things to entertain the chimpanzees. As I was picking up trolls that had clearly been bitten into (some were ripped almost in half!) I was thinking that there must have been some sort of troll forage. Jackie confirmed that they did indeed have frozen watermelon in troll dolls as a forage the day before. I started wondering what the average person must think when they hear that caregivers fill troll dolls with frozen watermelon as a fun project. It must sound so strange! But the chimpanzees really love stuff like that, and we try to take advantage of the kind of enrichment we have (and we have TONS of trolls since they are a Foxie favorite) and make it even more enriching.
Today we set up a blanket fort—we tied blankets together and made a really low ceiling for the chimps to walk under. It was sort of like the day we draped some blankets over the barrels, but this was bigger and more spread out. And it was enriching for the chimps, so I think we succeeded in our goal!
The blanket fort lasted a pretty long time, however I just saw Jody taking it down in order to nest with the blankets. She seemed pretty content with all the blankets she managed to collect since they were tied together.
Toning it down a notch
Missy probably has more energy than anyone I know, especially when she’s playing. But it’s fascinating to watch her play with Negra. Negra doesn’t play too often and is usually pretty subdued about it when she does, so watching Missy tone it down a notch in order to get to play with the Queen is really pretty special.
Bipedal Annie
Following the video yesterday, here are some shots from this morning of Annie walking bipedally. She does this a lot on Young’s Hill. It’s obviously not the primary way of locomotion for chimpanzees, although we do see it here and there. There are a bunch of theories about why bipedal locomotion evolved – maybe based on the need to look over the tall grasses as our ancestors became less arboreal, maybe the need to carry food or babies, or, the new theory JB shared with me this morning as we were watching the chimps forage on the hill – the “this just feels icky on my hands” theory. I’ll have to look that one up, but I think it might be the one that fits Annie best?!
Cattail forage
The chimps are able to find plenty of native plants to eat on Young’s Hill but they still love cattails, which only grow by the edge of the pond on the sanctuary grounds. So once and a while we cut some down and hide them throughout their enclosure.
