I had to make a new post this is what they look like in the desert , the ones for use are sand blasted .
Part of the skeleton of a dead cholla stem, showing the reticulate pattern of the woody support tissues.
The dense branches of living chollas frequently are used as sites for nest-building by desert birds such as the cactus wren and curve-billed thrasher. The dead remains and fallen segments of chollas also are used frequently by desert wood rats (Neotoma species) for covering and protecting the entrances to their nests.
