Keep them guessing

Foxie loves playing chase with her caregivers. To start a game, she passes one of her dolls to us and then runs or spins away. As she waits for us to catch up, she takes a big gulp of water from the fountain and holds it in her mouth. Is it because all that running…

Negra’s nest

The other night, while doing chimp counts during closing rounds, I climbed a ladder to look in the loft and found Negra building this magnificent nest.

The great thaw

We’re nearing the end of the chimps’ ninth winter here at CSNW and while chimpanzees aren’t naturally cold weather animals, they have adapted quite well.

Further down, Burrito and Foxie paired off, each using one arm to groom while the other wrapped around their…

Visiting Hours

Health care workers know that emotional support from friends and family can play an important role in the healing process. So while Negra might be on restricted activity for a few days, she still gets regular visits from her family. Then again, who needs family when you’ve got a constant stream of peanuts, peanut butter,…
