One of the websites I read about Hominidae (they include gorillas and chimps
in the family, which I don't) states "All make and use nests." So I looked
for info on gorilla and chimp nests. Their nests are several tree branches
bent together to make a platform, or they make ground nests. They use them
for one night and then move on. Such a thing I would call ckana gi'enai zdani.
