Way back in 2010, we replaced a bunch of caged windows with chimp-proof glass. On the greenhouse (what we used to call the outdoor area) side of things, this created deep window sills that the chimpanzees appreciated right away.

Missy was using her private cubby time to sift through some nut and seed shells:
While Burrito decided to get REALLY comfortable in his sill:
