The use of tool by animals is surprisingly rare. This is similar to the fact that all birds, even first time breeders within a species build identical nests.

to have and raise children. In the case of Acorn Woodpeckers, they are cooperative breeders (as with many other polygynandrous species), which seems to predispose species to polygynandry. Alpine Accentors, on the other hand, are not cooperative breeders and females typically have very little to do with each other. Davies et al.
